Magnesium Citrate & Magnesium Bisglycinate:

As many as 50% of North Americans consume too little magnesium. This can result in Magnesium deficiency, causing symptoms such as muscle aches, fatigue, weakness, and irritability. Magnesium is essential for a the functioning of a healthy immune system. Additionally, it can help increase bone strength and help the heart beat rhythmically by allowing it to relax between beats. Deficiency is common and can affect overall mood. Magnesium is known as the anti-stress mineral, it works fast to calm a racing mind, relax muscles and help normalize the heart rate.

L-theanine: It is a calm-enhancing amino acid. It promotes relaxation and reduces nervous tension by stimulating alpha wave activity in the brain.

Questions?

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.

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.

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.

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.

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.
