Formulation Notes

Gentle on the stomach magnesium glycinate

Magnesium is an essential nutrient required for muscle and brain activities, nerve function, and bone health. It is also critical for energy production in the body. Sixty percent of the body's magnesium is stored in the bones, and over 25% is stored in muscle.

Dietary surveys show that many people are susceptible to magnesium deficiency. Our magnesium glycinate 400 mg is a superior form of this essential nutrient.
