TruMarine® Collagen

Is TruMarine Collagen only good for skin, hair and nails?

Not even close. TruMarine Collagen is the most abundant protein in your body, found wherever there is structure: skin, joints, bones, gut lining, organ linings, hair, and nails. People take TruMarine® daily for many different reasons: to reduce joint pain, support post-workout recovery, strengthen hair and nails, improve skin hydration and elasticity, and support bone density over time.

What often surprises people is how much it supports from the inside out. Glycine, one of TruMarine®'s key amino acids, has a natural calming effect on the nervous system and supports deeper sleep. TruMarine Collagen also plays a critical role in gut health by supporting the integrity of the gut lining and in immune function, since a healthy gut is foundational to a strong immune system.

The benefits compound the longer you take it consistently.

Is TruMarine® Collagen Type 1, 2, 3?

You'll see brands marketing collagen by type as if more types mean more benefits. It doesn't. Type is simply a reflection of the source. Chicken sternum gives you Type II. Bovine hide gives you Type I and III. Marine gives you Type I, the most abundant collagen in the human body, accounting for over 90% of your body's total collagen.

What actually matters is source, purity, and bioavailability. TruMarine® is Premium Select Grade Type I marine collagen, wild-caught, single source, and clinically proven to deliver 1.5x greater bioavailability than other leading brands. Chosen for purity and potency, not categorized for marketing purposes.

Type is a category. Source is everything.

What are the benefits of withinUs® TruMarine® Collagen?

Visibly firmer, more hydrated skin. Stronger hair and nails. Reduced joint pain and improved mobility. Better bone density over time. And because TruMarine® has 1.5x greater bioavailability than other leading brands, your body actually absorbs and uses what you're taking.

Learn more here.

What makes TruMarine® Collagen superior/why choose TruMarine® Collagen?

Not all collagen is created equal.

When it comes to collagen, the source matters. withinUs® TruMarine® Collagen is derived exclusively from the scales of wild-caught fish, a sustainable and premium source. Collagen peptides from wild-caught fish scales are clinically shown to be among the purest and most bioavailable forms available. This means TruMarine® Collagen is absorbed more efficiently into the bloodstream, allowing for a lower daily serving while still delivering superior results.

TruMarine Collagen vs Bovine Collagen

If you've tried a different collagen brand before and didn't notice a difference, source and absorption are likely why.

TruMarine® is wild-caught from the deep, clean waters of the South Pacific, sustainably sourced, and ultra-pure, with a low molecular weight that allows your body to absorb and use significantly more than any bovine, porcine, or avian source.

Not all marine collagen is equal either. TruMarine® is the only Premium Select Grade marine collagen in North America, clinically proven to deliver 1.5x greater bioavailability than other leading brands. That difference shows up in your serving size. TruMarine® delivers results at just 5 grams daily. Many bovine collagens require 10 to 20 grams to achieve a comparable effect, and pills or gummies absorb even less.

You'll also see multi-collagen products marketing a blend of types as a benefit. Combining collagen from multiple animal sources doesn't multiply the benefits; it dilutes the purity. You have no way of knowing the quality of each source, how they interact, or what you're actually absorbing. A single, ultra-pure source at the right dose will always outperform a cocktail of mixed animal origins.

Collagen sourced from land animals comes from skin and bones, which absorb contaminants and impurities from the animals' environment and food supply. Those impurities affect the final product, which is why so many bovine and porcine collagens have an unpleasant odour or taste and need to be flavoured or sold in capsule form to mask it.

TruMarine is virtually tasteless and odourless and dissolves completely. That's a reflection of purity.

What certifications does TruMarine® Collagen have?

withinUs TruMarine® Collagen is verified, tested, and transparent at every step.

Every lot produces a Certificate of Analysis, meaning every batch is tested and documented before it ever reaches you. It is manufactured in Canada under strict Good Manufacturing Practices, in a sterile facility free of gluten, nuts, soy, and common allergens.

Wild-caught and sustainably sourced. Third-party tested. Non-GMO Project Verified. Kosher certified. Health Canada NPN licensed.

withinUs is B Corp certified at the brand level, meaning our commitment to quality, people, and the environment is independently verified.

Testing is not something we do to check a box. It is how we have operated since day one, and it is not something we will ever compromise on.

How do I take withinUs® TruMarine® Collagen?

TruMarine® is virtually tasteless and odourless, so it works in almost anything without changing the flavour.

Add it to hot or cold liquids, stir it into food, or blend it into a smoothie. It dissolves instantly with no gritty texture or aftertaste.

Our favourites: coffee, tea, lemon water, smoothies, juice, yogurt, and oatmeal.

Does withinUs® TruMarine® Collagen contain shellfish?

No. TruMarine® Collagen is sourced exclusively from wild-caught, sustainably sourced fish and contains no shellfish or shellfish derivatives of any kind.

Is TruMarine Collagen sourced from wild-caught fish vs farmed?

TruMarine® is sourced exclusively from the deep, clean waters of the South Pacific, wild-caught from small, independently managed fisheries committed to preventing overfishing. It is Premium Select Grade, the highest purity standard available, and the only marine collagen of its kind in North America.

Crafted into peptides using a proprietary, chemical-free method with pure volcanic spring water.

No preservatives. No stabilizers. Nothing added.

How long does it typically take to experience benefits?

withinUs TruMarine® Collagen has undergone extensive third-party, double-blind studies to ensure clinically proven results. Every person is different, and TruMarine® is not a quick fix. Clinical studies show that people taking 5 grams daily typically notice benefits within 4 to 8 weeks. But the deeper benefits, stronger bones, improved joint comfort, and long-term skin health, build over time with consistency.

This is a foundation supplement. The results compound the longer you take it.

How much TruMarine® Collagen should I take per day?

Clinical studies support 5 grams daily of TruMarine Collagen, approximately one scoop or stick pack, as the effective dose for most people. For joint health specifically, we recommend starting with 10 grams daily for the first four weeks, then dropping to 5 grams as a maintenance dose.

Taking more than 5 to 10 grams daily is not harmful, but consistency at the right dose matters more than quantity. Five grams every day will always outperform ten grams taken sporadically.

Is it safe to take withinUs® TruMarine® Collagen while pregnant or breastfeeding?

TruMarine® Collagen is a naturally sourced product with no artificial ingredients, fillers, or additives. That said, every pregnancy and postpartum journey is different. We always recommend consulting your healthcare practitioner or midwife before adding any supplement to your routine during pregnancy or while breastfeeding. They can advise based on your individual health needs and the most current Health Canada guidelines.

Is it safe for children/teenagers to take TruMarine® Collagen?

Your body's natural collagen production begins to slow in your mid-twenties, but there is no reason you can't start earlier as a preventative measure. TruMarine® is a naturally sourced product with no artificial ingredients, fillers, or additives. As with any supplement for children or teenagers, we recommend consulting with a healthcare practitioner if you have specific questions or concerns.

Are there any side effects from taking withinUs TruMarine® Collagen?

TruMarine® is a naturally sourced marine collagen peptide with no artificial ingredients, fillers, or additives. Side effects are rare. As with any supplement, some people may experience mild gastrointestinal sensitivity, particularly when first introducing it. If you have specific health concerns, are pregnant or breastfeeding, or take prescription medications, we recommend consulting your healthcare practitioner before use.

ReHydrate

Why did you include 1g of organic cane sugar in your ReHydrate?

The 1 gram of organic cane sugar in ReHydrate isn't filler. Glucose is your body's primary fuel source and plays a direct role in how quickly electrolytes are absorbed. That small amount of sugar is what enables the electrolytes to move into your cells efficiently, which is the whole point of a hydration product. It is functional, not decorative.

Is drinking water just as effective as taking an electrolyte?

Not quite. When you are already dehydrated, drinking water alone can actually dilute the electrolytes remaining in your body, making things worse. Electrolytes do two things water can't: they signal your body to retain fluid, and they restore the mineral balance your cells need to function properly.

ReHydrate replaces what water alone cannot.

Can you take ReHydrate while pregnant or breastfeeding?

ReHydrate is formulated with organic, non-GMO ingredients and no artificial additives. It is a far better choice than other electrolytes or sports drinks on the market. As with any supplement during pregnancy or while breastfeeding, we recommend consulting your healthcare practitioner or midwife before use. Every pregnancy is different, and your provider is best placed to advise based on your individual health needs.

For TruMarine® Collagen specifically, Registered Dietitian Kim McDevitt has written about her personal experience taking it throughout her pregnancies and postpartum recovery.

https://withinus.ca/blogs/livetru/taking-collagen-throughout-my-pregnancy-kim-mcdevitt-rhn.

Can children take ReHydrate?

ReHydrate is formulated with organic, non-GMO ingredients and contains no artificial additives. While our recommended serving is based on adult consumption, children can absolutely benefit from it at a smaller dose. We suggest starting with half a serving and consulting your healthcare practitioner if you have any specific health concerns.

Do you use stevia in this product?

Yes. ReHydrate uses a small amount of certified organic stevia extract to counter the natural bitterness of the electrolyte minerals. Stevia is a natural, plant-based sweetener derived from the leaves of Stevia rebaudiana with no artificial additives.

Not everyone loves the taste of stevia, our founder included. We explored every natural alternative, but adding more sugar wasn't the right choice for a hydration product, and other options either weren't certified organic or weren't approved by Health Canada. Certified organic stevia was the cleanest, most responsible choice. She drinks ReHydrate every day and doesn't taste it.

Magnesium

What are the benefits of Magnesium L-Threonate blend?

Magnesium L-Threonate is uniquely able to cross the blood-brain barrier, working in the brain directly where other forms of magnesium cannot reach.

Combined with magnesium bisglycinate for full body relaxation, it creates two magnesium pathways in one formula.

L-theanine promotes a calm, present state without sedation, bridging the nervous system response between both magnesium forms.

TruMarine® Collagen delivers glycine, an inhibitory neurotransmitter that lowers core body temperature at night and supports deep sleep, alongside hydroxyproline and proline to signal overnight tissue repair and rebuilding.

This is not a magnesium supplement. It is a recovery and restoration system.

Learn how to choose the right magnesium for you.

What is the benefit of Magnesium Citrate blend?

We have chosen to include a combination of magnesium citrate and magnesium bisglycinate in order to offer a product with maximum absorption that is easy on the digestive system.

Magnesium Citrate + TruMarine® Collagen is built for physical recovery.

Citrate is a well-absorbed form of magnesium that supports muscle relaxation, reduces cramping, and promotes restful sleep. It also supports healthy digestion and regularity. Start with one scoop and adjust from there.

Both formulas contain magnesium bisglycinate, L-theanine, and TruMarine® Collagen as the foundation. The citrate form extends that effect into the digestive and muscular systems, while L-threonate extends it into the brain.

Not sure which is right for you? Read our full comparison guide.

Does it contain a full serving of TruMarine® Collagen?

Each scoop of withinUs Magnesium contains 2.5 grams of TruMarine Collagen; two scoops bring you to the full 5-gram daily dose.

But the real answer goes beyond serving size. TruMarine in each product is doing something different depending on when you take it and what it is paired with. Your morning TruMarine Collagen supports skin, joints, and gut health. ReHydrate in the afternoon delivers TruMarine alongside electrolytes for cellular hydration and recovery. Magnesium at night pairs TruMarine's glycine with bisglycinate and L-theanine for nervous system calm, deep sleep, and overnight repair.

Taking it across multiple products throughout the day means your body is receiving consistent support from morning through to recovery overnight.

That is the withinUs stack.

How do I make it/use withinUs Magnesium blends?

Add one to two scoops into 250ml of room temperature water (you can add ice later, as some people do) or into hot water or herbal tea and stir. A squeeze of fresh lemon makes it even better. Best taken in the evening as part of your wind-down routine.

Powder vs Tablet? Which is better?

withinUs magnesium in powder form absorbs significantly faster and more completely than tablets or capsules. Your body can only use a fraction of what's in a compressed pill, and most tablets require stabilizers, fillers, and binding agents just to hold their shape. A powder dissolves directly with nothing added, and gets to work immediately.

And unlike any tablet on the market, ours delivers TruMarine® Collagen, L-theanine, and bisglycinate together in a single serving.

Does withinUs Magnesium + TruMarine Collagen contain caffeine or sedatives?

It contains no caffeine, no melatonin, no sedatives.

TruMarine® Magnesium works with your body's natural sleep processes rather than overriding them. We made a deliberate decision not to include melatonin. While melatonin is widely used, it can cause morning drowsiness, vivid dreams, headaches, and changes in blood pressure. We wanted a formula that supports deep, restorative sleep without the next-day side effects

Can I ingest withinUs Magnesium while pregnant or breastfeeding?

withinUs Magnesium + TruMarine Collagen is formulated with naturally sourced ingredients and no artificial additives.

That said, every pregnancy and postpartum journey is different. We always recommend consulting your healthcare practitioner or midwife before adding any supplement to your routine during pregnancy or while breastfeeding.

What’s in Magnesium L-Threonate + TruMarine® Collagen?

Magnesium L-Threonate is a highly bioavailable form of magnesium that is uniquely able to cross the blood-brain barrier, meaning it reaches the brain directly rather than staying in the bloodstream. This makes it distinct from other forms of magnesium, which work primarily in the body.

Our L-Threonate formula combines this brain-specific magnesium with magnesium bisglycinate for full body relaxation, L-theanine for calm nervous system support, and TruMarine® Collagen for overnight tissue repair and recovery.

Two magnesium pathways, one formula.

What are the difference between the two magnesium blends you offer?

Both formulas share the same foundational stack of magnesium bisglycinate, L-theanine, and TruMarine® Collagen. The difference is in the second magnesium form and where it works in your body.

Magnesium Citrate pairs bisglycinate with citrate, a well-absorbed form that supports muscle relaxation, physical recovery, digestive health, and restful sleep. A strong choice for those focused on body-level recovery and regularity.

Magnesium L-Threonate pairs bisglycinate with L-threonate, a brain-specific form uniquely able to cross the blood-brain barrier. The better choice if you are looking for neurological support, stress reduction, and calm focus alongside the physical recovery benefits.

Not sure which is right for you? Read our full comparison guide.

Is Magnesium L-Threonate blend hard on my stomach?

Magnesium L-Threonate should not be hard on your stomach.

This formula uses magnesium bisglycinate as its base, widely considered the gentlest form of magnesium for digestion. If you are experiencing sensitivity, try taking it with food or reducing to half a serving to start.

While everyone benefits from magnesium, why this formulation?

Most people are deficient in magnesium and don't know it. Stress, poor sleep, muscle tension, brain fog, and low energy are all common signs. Magnesium is involved in over 300 biochemical processes in the body, and most people simply aren't getting enough from diet alone.

Most magnesium supplements are of a single ingredient addressing a single symptom. withinUs Magnesium was built differently. Two forms of magnesium (L-threonate & bisglycinate as well as citrate & bisglycinate) work in two different systems, L-theanine bridging the nervous system response, and TruMarine® Collagen supports overnight repair from the inside out.

If you have tried magnesium before and not noticed much difference, the form and the formula are likely why.

Wondering about Magnesium L-Threonate and what are the benefits?

Magnesium Bisglycinate — the most bioavailable form of magnesium for the body. Supports deep muscle relaxation, nervous system calm, and is gentle on digestion.

Magnesium L-Threonate — a brain-specific form of magnesium uniquely able to cross the blood-brain barrier, working where other forms of magnesium cannot reach.

L-Theanine — promotes alpha brain waves, that calm, present state where you're relaxed but not sedated. Bridges the gap between the two magnesium pathways.

TruMarine® Collagen — delivers glycine, an inhibitory neurotransmitter that supports deep sleep and overnight repair, alongside hydroxyproline and proline to rebuild tissue while you rest.

Four ingredients. Every one of them earns its place.

Do I need to take the magnesium at night? Will it make me drowsy?

You don't have to, but evening is when your body does its deepest repair work and when the formula works hardest. That said, it won't make you drowsy, so it can be taken any time.

Many customers use both and take L-Threonate during the day for calm and stress support, and Citrate in the evening for physical recovery and sleep.

Creatine Monohydrate

What are the benefits of supplementing with creatine?

Creatine is a naturally occurring compound that helps your body produce energy at the cellular level. When your energy demands increase, such as during periods of stress, lack of sleep, recovery, or physical activity, additional creatine can help replenish your body’s stores, supporting overall vitality.

While creatine is well known in the fitness world, emerging research continues to highlight its broader wellness benefits, including potential support for:

  • Reducing feelings of fatigue and exhaustion
  • Supporting muscle preservation with age (helping combat sarcopenia)
  • Enhancing brain function, focus, and cognitive performance
  • Supporting recovery and rehabilitation
  • Contributing to overall energy and vitality

At withinUs, we’ve chosen a clinically proven form of creatine, paired with our premium TruMarine® Collagen, to help you experience these benefits in a clean, effective, and easy-to-use blend.

*Information referenced is based on clinical research on Creavitalis® creatine monohydrate and supported by Health Canada NPN approval. For additional information, please visit the Creavitalis® website.

How much creatine is in each serving?

Each scoop contains 2.5 grams of Creavitalis® creatine monohydrate. Creavitalis® is highly bioavailable, so this dose is effective on its own. If you want the full 3g daily serving of Creavitalis® creatine, you can either take a rounded scoop of Creatine Monohydrate + TruMarine® Collagen, or take 2 scoops per day to get both the full creatine serving and a full serving of TruMarine® Collagen.

Does Creatine Monohydrate + TruMarine® Collagen replace the TruMarine® Collagen I am taking daily?

This product is not intended to replace your daily TruMarine® Collagen. It is designed as an addition to your wellness routine, helping you incorporate creatine while still supporting your collagen intake.

How much TruMarine® Collagen is in the new Creatine Monohydrate + TruMarine® Collagen?

Each scoop contains half the daily recommended serving of TruMarine® Collagen (2.5 grams). We formulated it this way to make it easy to mix and match with other withinUs products, such as our Magnesium products or ReHydrate, so you can build a routine

What is creatine? 

Creatine is a naturally occurring compound your body makes from three amino acids: arginine, glycine, and methionine, primarily in the liver and kidneys. It is also found naturally in red meat and fish like salmon, sardines, and herring.

Its primary role is energy. Creatine is stored in your muscles as phosphocreatine and used to rapidly regenerate ATP, the fuel your cells run on during high intensity effort. When your muscles need fast energy, phosphocreatine is what they reach for first.

Two of the three amino acids that make creatine, arginine and glycine, are also found in TruMarine Collagen. That is not a coincidence. It is part of why this combination works as well as it does.

Why combine TruMarine Collagen with Creatine?

Most creatine products stop at muscle performance. This one doesn't.

Creatine fuels fast-twitch muscle performance: strength, power output, and recovery. That part is well known. What most people don't know is what collagen adds to that picture.

Exercise doesn't just stress your muscles. It actively remodels connective tissue, tendons, ligaments, and cartilage. That tissue depends on glycine and arginine to repair and rebuild. TruMarine Collagen delivers both.

Glycine goes further still. Beyond its role in connective tissue, it is a precursor to glutathione, your body's primary antioxidant, supports your body's anti-inflammatory response, and is linked to improved sleep quality, which is when your body does its deepest repair work.

Arginine is a precursor to nitric oxide, which dilates blood vessels and improves the delivery of nutrients and oxygen to muscles during and after training.

Creatine alone supports muscle performance. Combined with TruMarine Collagen you are also supporting joint integrity, tissue repair, circulation, and recovery. These two ingredients are genuinely complementary. Not just bundled together because it made sense on a label, but because the science supports what each one does for the other.

When should I take creatine? 

Creatine does not need to be timed precisely the way some supplements do. Consistency matters far more than timing.

That said, research suggests taking it close to your workout, either just before or just after, may offer a slight advantage for muscle performance and recovery. On rest days, timing is irrelevant. Take it whenever it fits your routine.

withinUs Creatine is combined with TruMarine Collagen, which supports connective tissue repair and recovery. Taking it post-workout means both ingredients are available when your body is actively repairing and rebuilding, which is when they are most useful.

How much water do I need to mix creatine with?

Mix well into at least 250ml of water and drink it promptly. Creatine that sits undissolved can settle at the bottom of your glass, and when swallowed that way, it draws water into your digestive tract rather than your muscles, which is the most common cause of bloating. Creavitalis is micronized for better solubility, but mixing well and drinking straight away makes a real difference.

Prefer to take it in your morning coffee? That works too. Our choice of creatine does not denature in hot liquids (like TruMarine Collagen). Mix it in, drink it promptly, and you are good to go.

Is creatine just for athletes or bodybuilders?

This is one of the most outdated ideas in the supplement industry. Creatine has been studied more extensively than almost any other supplement and the research goes well beyond athletic performance.

Creatine supports muscle retention, strength, cognitive function, reduced fatigue, and preserved lean mass. These benefits matter for everyone, not just people training for performance. Particularly for women over 40, where muscle mass naturally begins to decline and cognitive sharpness becomes a priority, creatine is one of the most well-supported supplements available.

The gym culture association stuck because athletes were the first to use it widely. But the science was never just about sport. It was always about what happens when your cells have the energy they need to function at their best.

Can I get enough creatine from food alone?

Technically yes, but not practically. Your body produces about 1 to 2 grams of creatine per day on its own. A diet that includes red meat and fish adds another 1 to 2 grams, bringing your daily total to roughly 2 to 3 grams.

The research on creatine's performance and recovery benefits consistently uses 3 to 5 grams per day. To reach that from food alone, you would need to eat roughly 750 grams to 1 kilogram of raw beef or salmon every single day. That is not realistic for most people, and cooking degrades creatine further, so cooked portions deliver even less.

Vegetarians and vegans have notably lower creatine stores and often see the most significant response when they start supplementing, simply because they are starting from a lower baseline.

A daily 3-gram serving of withinUs Creatine + TruMarine Collagen is the most efficient and consistent way to maintain the levels the research supports.

Do I need to do a loading phase when taking creatine?

No. Loading phases, where you take 20 grams or more daily for the first week, were popularized in early sports nutrition research as a way to saturate muscle creatine stores quickly. They work, but they also significantly increase the risk of digestive discomfort and are unnecessary for most people.

A consistent daily dose of 3 to 5 grams will reach the same saturation point within three to four weeks with none of the side effects. For long-term health and recovery, which is what withinUs is designed for, steady and consistent always wins over aggressive and fast.

I am over 40, is creatine right for me?

It may be one of the most important supplements you can take after 40.

Creatine production in the body naturally declines with age. The enzymes responsible for synthesis become less active, muscle mass decreases so less creatine is stored and used, and dietary intake often drops as well. Research suggests muscle creatine levels can decline 20 to 30 percent by your 50s and more significantly into your late 60s.

The benefits of supplementing become more meaningful as you age: muscle retention and strength, which matters enormously for bone density and fall prevention, reduced fatigue, preserved lean mass, and support for cognitive function, since the brain relies on phosphocreatine for energy too.

This is not a performance supplement for athletes. It is a longevity supplement for anyone who wants to stay strong, sharp, and functional as they age.

Can I take creatine with my other withinUs products?

Yes, and it was designed with that in mind.

TruMarine Collagen and Creatine are already combined in one product because the two ingredients are genuinely complementary. The amino acids in TruMarine, particularly glycine and arginine, support connective tissue repair, circulation, and recovery in ways that directly enhance what creatine does for muscle performance.

Stacking with Magnesium adds nervous system support and overnight recovery. ReHydrate supports cellular hydration, which matters because creatine draws water into muscle cells and staying well hydrated amplifies that effect.

The withinUs stack is not a collection of unrelated products. Every combination was considered.

Does creatine cause hair loss?

This concern comes from a single study published in 2009 involving rugby players who took creatine for three weeks. The study found an increase in DHT, a hormone associated with hair loss, but importantly, it did not measure or record any actual hair loss in participants.

No study has replicated these findings or established a direct link between creatine supplementation and hair loss. The current scientific consensus is that creatine does not cause hair loss.

If you have a genetic predisposition to hair loss, DHT can be a factor worth discussing with your doctor. But the evidence that creatine meaningfully raises DHT, or that doing so leads to hair loss, is not strong enough to support the concern that has spread online.

How long until I notice results from creatine?

It depends on what you are looking for and where you are starting from.

Most people notice improved energy and workout performance within two to four weeks as muscle creatine stores build up. Physical changes like improved strength and lean muscle retention take longer, typically six to eight weeks of consistent daily use.

The less visible benefits, bone density support, cognitive function, and connective tissue health, build over months. These are the benefits that matter most for long-term health, and they are not the kind you notice in a single workout. They are the kind you notice when you realize you feel stronger, sharper, and more resilient than you did a year ago.

Creatine is a long-game supplement. Take it every day and let it compound.

Is creatine safe for my kidneys?

For healthy kidneys, creatine is safe and one of the most well-researched supplements available. Decades of studies in healthy individuals have not shown creatine to cause kidney damage.

There is one thing worth knowing. When you supplement creatine, your body metabolizes more of it, which produces more creatinine, a normal waste byproduct that kidneys filter out. This can cause creatinine levels to read slightly higher on a standard blood panel, which can look like impaired kidney function. It is not. It is a measurement artifact, not a health issue. If you are supplementing creatine and getting bloodwork done, let your doctor know so they can interpret the results correctly.

If you have a history of kidney disease or reduced kidney function, the additional creatinine load is a legitimate concern. Kidneys that are already compromised are being asked to do more work. In that case, we recommend consulting your healthcare provider before use.

Coconut Creamer

How do I prepare Coconut Creamer™ + TruMarine® Collagen?

Add one to two tablespoons to your hot beverage of choice, and we like using a hand-frother or in a blender. It works beautifully in coffee, matcha, tea, or smoothies.

Does withinUs Coconut Creamer® + TruMarine® Collagen contain carrageenan?

No. withinUs Coconut Creamer™ is made with certified organic, carrageenan-free coconut milk powder, derived from coconuts grown without fertilizers, nitrogen, or chemicals.

How much TruMarine collagen does Coconut Creamer contain?

Each serving of Coconut Creamer™ contains 2.5 grams of TruMarine® Collagen, half the recommended daily dose. Pair it with a second withinUs product containing TruMarine® to reach your full 5 grams across the day, or take an additional serving.

Is it normal for the Coconut Creamer to clump in the jar?

Completely normal. Coconut Creamer contains no stabilizers, flow agents, or preservatives, so the natural coconut oils can harden in cooler temperatures. Simply break up any clumps with the back of a dry spoon. Once added to a hot beverage, it dissolves completely and tastes exactly as it should.

What does Coconut Creamer taste like? Does it taste like coconut?

Yes, but subtly. Coconut Creamer has a light, natural coconut flavour that complements your beverage without overpowering it. No artificial flavours, no sweeteners, nothing added. 2 ingredients: certified organic coconut milk and TruMarine Collagen.

Matcha Misto

Where is your organic matcha sourced from?

withinUs Matcha Misto uses matcha sourced exclusively from Uji, Kyoto, the historic birthplace of Japanese matcha and the region that has set the standard for quality for over 800 years. First harvest, shade-grown, and stone-ground.

Three ingredients: organic matcha, TruMarine® Collagen, and organic coconut milk.

Premium, authentic Japanese matcha is made exclusively from shade-grown tencha leaves that are destemmed, deveined, and stone-ground into a fine powder. Ground green tea leaves are not matcha.

The plant, the process, and the nutritional profile are entirely different. If a product doesn't specify tencha and stone-ground, it is green tea powder, regardless of what it says on the label.

You will also see "ceremonial grade" used widely in the market. It is not a regulated or certified standard. Anyone can use the term. What actually matters is origin, harvest timing, and how it is processed.

That is where withinUs starts and where most others stop.

Does withinUs Matcha Misto need to be prepared with a whisk?

A whisk is traditional for matcha preparation, but not necessary for Matcha Misto.

A handheld frother gives you the best result, smooth, frothy, and well blended. Add one to two tablespoons to warm water and milk of choice and mix thoroughly.

Does withinUs Matcha Misto™ contain a full serving of TruMarine® Collagen? Can I mix the two?

Each serving of withinUs Matcha Misto™ contains approximately half the daily recommended serving (2.5 grams) of withinUs TruMarine® Collagen.

Clinical studies and research have proven that unlike any other source of collagen (including fish skin), wild-caught fish scale collagen (withinUs® TruMarine® Collagen) has superior absorption levels and 5 grams is the daily requirement.

Other collagen products often recommend 10-20g of their collagen, this is due to lower quality and bioavailability of the material.

Consuming more than 5 grams of TruMarine® Collagen per day is not harmful.

Is Matcha Misto safe to consume while pregnant or breastfeeding?

Matcha Misto is made with three simple, naturally sourced ingredients: matcha, TruMarine Collagen, and organic coconut milk. That said, every pregnancy and postpartum journey is different. We always recommend consulting your healthcare practitioner or midwife before adding any supplement to your routine during pregnancy or while breastfeeding.

Is it normal for the Matcha Misto having some clumps in the jar?

Completely normal. Matcha Misto contains no stabilizers, flow agents, or preservatives, so the natural coconut oils can harden in cooler temperatures. Simply break up any clumps with the back of a dry spoon. Once added to a hot beverage, it dissolves completely.

Is Matcha Misto sweetened/flavoured?

No. Matcha Misto contains no added sweeteners, preservatives, or colouring. The subtle natural sweetness comes entirely from the organic coconut milk. Nothing artificial, nothing added.

Does Matcha Misto contain caffeine?

Yes, but significantly less than coffee. A serving of Matcha Misto contains approximately one-third the caffeine of a cup of coffee. The difference is how it feels. L-theanine, a naturally occurring amino acid in matcha, slows the release of caffeine and promotes a calm, focused state.

No spike, no crash, no jitters.

TruOrganic Matcha

How is TruOrganic Matcha different from brewed green tea?

With green tea you steep the leaves and discard them. With matcha, you consume the whole leaf, which has been shade-grown, dried, and stone-ground into a fine powder.

The leaves used for matcha are called tencha, and the shade-growing process dramatically increases their concentration of chlorophyll, antioxidants, L-theanine, and EGCG compared to standard green tea leaves.

The result is that one cup of matcha delivers the nutritional equivalent of approximately ten cups of brewed green tea. You are not steeping a fraction of what the leaf has to offer. You are getting all of it.

Why is it important to buy matcha sourced from Japan versus China?

Matcha originated in Japan over 800 years ago, and the growing practices have been refined over centuries, specific to the soil, climate, and agricultural traditions of the region. Chinese growers have attempted to replicate these conditions, but geography and the absence of that generational expertise mean the result is simply not comparable.

There is also a quality control concern worth noting. Japan has some of the most rigorous agricultural testing standards in the world. Chinese matcha, including some products marketed as organic, has in some cases been found to contain elevated levels of lead due to soil contamination.

We source exclusively from Uji, Kyoto and hold JAS/JONA, USDA, and Canadian Organic certifications.

It is a deliberate decision about what we are willing to put in our products and what we are not.

Where is withinUs TruOrganic Matcha sourced from?

TruOrganic Matcha is sourced exclusively from Uji, Kyoto, the historic birthplace of Japanese matcha and the region that has defined quality standards for over 800 years.

First harvest, shade-grown tencha leaves, stone-ground into a fine powder.

Certified organic through JAS/JONA, USDA, and Canadian Organic.

How do I make matcha?

Heat water to 75 to 80°C. Do not use boiling water, as it will scald the matcha and cause bitterness.

Add ¼ to ½ tsp of TruOrganic Matcha to a bowl and pour 60ml of warm water over it. Whisk into a smooth paste, then add another 70 to 100ml of water and whisk in a W-shaped motion until a layer of foam forms on the surface.

Pour into your favourite mug and enjoy as is, or top with steamed milk of your choice for a matcha latte.

Is TruOrganic Matcha sweetened/flavoured?

No. TruOrganic Matcha is 100% pure, certified organic Japanese matcha. Nothing added, nothing removed.

Can I add TruMarine Collagen into TruOrganic matcha?

TruOrganic Matcha is 100% pure matcha with nothing added.

That said, adding a scoop of TruMarine Collagen directly to your matcha is a great way to stack your routine in one cup. The benefits of TruMarine Collagen are not lost in hot beverages. If you love pure matcha but also want your collagen, this is the easiest way to get both.

How much caffeine is in withinUs TruOrganic Matcha?

A cup of TruOrganic Matcha contains approximately one-third to one-half the caffeine of a cup of coffee.

L-theanine, a naturally occurring amino acid in matcha, slows the release of caffeine and promotes calm, focused energy. No spike, no crash, no jitters.

Is TruOrganic Matcha plant based?

Yes. TruOrganic Matcha is 100% plant-based and vegan.
