What type of Magnesium do you use in withinUs TruMarine® Collagen + Magnesium?

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:

This form of magnesium is bonded to citric acid, which increases the rate of absorption. It is more bioavailable (1), meaning your body will absorb and utilize it most efficiently.

Magnesium Bisglycinate:

In this form, magnesium is bonded to the amino acid glycine. Glycine itself is a soothing neurotransmitter that enhances magnesium’s natural relaxation properties. This form is best/ideal for mental calm and relaxation.

Does withinUs TruMarine® Collagen + Magnesium contain a full serving of TruMarine® Collagen? Can I mix the two?

Each serving of withinUs Magnesium contains 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.

Can I ingest withinUs TruMarine® Collagen + Magnesium while pregnant or breastfeeding?

While withinUs TruMarine® Collagen + Magnesium consists of naturally sourced ingredients that have no known side effects, we always advise women that are pregnant/breastfeeding to consult their health care practitioner prior to use.

Many withinUs™ customers continue using our TruMarine® Collagen throughout their pregnancy/postpartum health and have found that it helps minimize their pregnancy mask/ melasma, and helps to firm and hydrate their skin. After pregnancy many women also find that their hair or nails become thin and brittle. withinUs TruMarine® Collagen helps replenish and restore collagen within the body, helps hair grow thicker, and nails to become healthier and stronger.

If you are pregnant or breastfeeding, and if you have any concerns, we recommend that you consult with your health care practitioner prior to use.

Does withinUs TruMarine® Collagen + Magnesium contain caffeine or sedatives?

No, withinUs TruMarine® Collagen + Magnesium does not contain any caffeine nor sedatives. We do NOT add melatonin to our product due to unwanted side-effects such as morning drowsiness, vivid dreams, small changes in blood pressure, nausea, headaches, and dizziness.

Is a Magnesium drink better than a tablet?

Magnesium supplements in liquid form are the best absorbed. Tablets, although convenient, are less effectively absorbed. Your body only uses a fraction of the magnesium in a tablet.

withinUs TruMarine® Collagen + Magnesium goes to work right away, creating the conditions for restorative rest.

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

This advanced formula includes two highly absorbable forms of magnesium (Magnesium L-Threonate and Magnesium Bisglycinate), L-Theanine to promote calm and focus, and our signature TruMarine® Collagen to support joint health, skin hydration, and tissue repair.

What is Magnesium L-Threonate and how does it differ from other forms of magnesium?

Magnesium L-Threonate is a unique form of magnesium that crosses the blood-brain barrier, allowing it to support cognitive health, memory, and focus. Unlike other forms of magnesium (like Magnesium Citrate or Magnesium Oxide), which mainly support muscle relaxation and digestion, Magnesium L-Threonate is designed to target the brain for enhanced mental clarity and cognitive function.

Will this new Magnesium L-Threonate blend be hard on my stomach?

This Magnesium L-Threonate blend is formulated to be gentle on the stomach, as it does not contain Magnesium Citrate, which can sometimes cause digestive discomfort. It’s a great option if you’re looking for calm and clarity without digestive side effects.

What are the Magnesium L-Threonate ingredients and what do they do?

1. Magnesium Bisglycinate — Gentle, easily absorbed, supports muscle relaxation and sleep.

2. Magnesium L-Threonate — Crosses the blood-brain barrier for better focus and clarity.

3. L-Theanine — Promotes calmness and improved sleep.

4. TruMarine® Collagen — Improves mood states such as fatigue and vigour, and increases the sense of restful sleep during the night.

Four ingredients. Real results.


Do I need to take this product at night? Will it make me drowsy?

While this blend supports more restful sleep, it won’t make you drowsy. It can be taken any time of day, whenever you need a moment of calm, focus, or relaxation.

What does “passes the blood-brain barrier” mean?

The blood-brain barrier is a protective shield that controls what substances can enter the brain. Magnesium L-Threonate is clinically shown to cross this barrier, allowing it to effectively support cognitive function, memory, and mental clarity.

Do I need to take this product at night? Will it make me drowsy?

While this blend supports more restful sleep, it won’t make you drowsy. It can be taken any time of day, whenever you need a moment of calm, focus, or relaxation.
