Among the minerals essential for the optimal functioning of our body is magnesium. Several forms are available on the market, but magnesium bisglycinate stands out for its high bioavailability and excellent tolerance.

What is magnesium bisglycinate?

Magnesium bisglycinate is a supplement where one magnesium molecule is bonded to two molecules of glycine, an important amino acid. This composition improves the solubility and absorption of magnesium by the body. Unlike other forms like magnesium oxide which can have laxative effects, bisglycinate is easily tolerated by the digestive system.

Why choose magnesium bisglycinate?

This form of magnesium is particularly beneficial for those with digestive sensitivities. Thanks to its "chelated" structure (union of a mineral and an organic molecule), its bioavailability is increased, thus facilitating its absorption. Bisglycinate easily crosses the intestinal barrier to diffuse effectively throughout the body.

The benefits of magnesium bisglycinate

Bone support

Magnesium is crucial for bone formation and density. It works synergistically with calcium and vitamin D to maintain strong bones, which helps prevent osteoporosis.

Muscle health

Magnesium bisglycinate helps relax muscles, prevent muscle cramps and spasms, and promote recovery after exercise. This makes it ideal for athletes.

Improved sleep

By promoting muscle relaxation and regulating the nervous system, magnesium bisglycinate can improve the quality of sleep, reducing insomnia and nighttime awakenings.

Blood sugar regulation

Magnesium is involved in the metabolism of glucose and insulin, thus contributing to the regulation of blood sugar. Supplementation may be beneficial for people with or at risk of diabetes, but it is always recommended to consult a doctor.

Digestive health

By acting on the intestinal wall and muscles, magnesium bisglycinate facilitates intestinal transit, which can help prevent constipation.
