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.

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

Magnesium L-threonate is a highly absorbable form of magnesium, an essential mineral that helps support muscle function, energy production, and overall cellular health. It’s designed to be gentle on the stomach while helping your body get the magnesium it needs to stay balanced and healthy.

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 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 — helps support muscle function, energy production, and overall cellular health, and designed to be gentle on the stomach.

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.
