Our Science

One mineral. Chelated for absorption. A lot of biology.

Here's what magnesium does in the body, what the chelated glycinate form changes, and the research behind each point, linked so you can read it yourself.

Why we chose chelated glycinate

We chose chelated glycinate for how it's absorbed and how gently it tends to sit with digestion. Magnesium glycinate is chelated: each magnesium ion is bound to two molecules of the amino acid glycine. Research suggests a portion is taken up intact through amino-acid (dipeptide) transport in the small intestine, and that this form is generally well tolerated.⁶³ Chelated organic forms like this one are well studied for their absorption and digestive tolerance.⁴⁵⁷ That's the whole idea behind Biomacell: a chelated glycinate form, with no added fillers.

Supports restful sleep*

In a randomized, double-blind, placebo-controlled trial of 155 adults reporting poor sleep, daily magnesium bisglycinate was associated with a greater improvement in sleep scores than placebo over four weeks.⁸ Broader reviews note that low magnesium status is linked to poorer sleep quality, while supplementation shows promise as a gentle way to support rest.⁹

Helps the body manage everyday stress*

Magnesium is involved in regulating the nervous system and the body's stress-response pathways.¹ A systematic review of intervention studies found that magnesium may help ease subjective feelings of anxiety and stress, particularly in people more vulnerable to them.¹⁰ Because everyday stress can increase how much magnesium the body loses, keeping intake adequate matters.¹⁰

Powers muscle & nerve signaling*

Magnesium is essential for normal muscle contraction and nerve transmission, acting as a counter-balance to calcium inside cells.¹¹¹ Reviews of skeletal-muscle physiology describe magnesium as critical for healthy muscle function and recovery, and note that low magnesium status is commonly seen alongside muscle complaints.¹¹

Part of a heart-healthy foundation*

The heart is a muscle, and magnesium contributes to normal muscle function. It also helps maintain normal electrolyte balance and a steady, normal heartbeat, part of the everyday machinery that keeps a healthy body running.¹

Why so many people fall short

Modern diets (refined foods, depleted soils, fewer whole grains and leafy greens) make it hard to hit the magnesium target from food alone. Reviews estimate that a large share of adults in the U.S. consume less than the recommended amount, and that subclinical magnesium shortfall is widespread.²¹² A single clean capsule a day is a simple way to help close that gap.

How to take Biomacell

Take 1 capsule daily with a meal, or as directed by your healthcare professional. Magnesium glycinate is gentle on the stomach, so it can be taken in the evening to fit a wind-down routine. Consistency matters more than timing, so take it daily, without interruption. If you are pregnant, nursing, taking medication, or managing a health condition, talk to your healthcare professional before use.
