Formulation Notes

Superior bioavailable chelate

Magnesium is one of the most important minerals in the body, but an estimated 75% of Americans are magnesium deficient. Magnesium plays a key role in over 300 enzymatic reactions, including supporting cardiovascular, bone, muscle, energy, and neurotransmitter processes. Source Naturals magnesium is attached ("chelated") to the amino acid glycine. The magnesium bis-glycinate combination enables efficient absorption, the glycinate allowing the magnesium to transfer easily across the intestinal wall. Increased absorption means more usable magnesium for your body's needs.

Suitable for vegetarians and Hypoallergenic: contains no yeast, dairy, egg, gluten, corn, soy or wheat. Contains no sugar, starch, salt, preservatives, or artificial color, flavor or fragrance.

Suitable for vegetarians and Hypoallergenic: contains no yeast, dairy, egg, gluten, corn, soy or wheat.
