What form of magnesium is in this product and how does it affect absorption?

This supplement contains magnesium bisglycinate chelate (also called diglycinate), where magnesium is bound to the amino acid glycine. This chelated form is designed to pass through the digestive tract more gently than inorganic forms such as magnesium oxide, reducing the likelihood of loose stools or stomach discomfort that some people experience with other magnesium types. The glycine bond also supports efficient uptake in the small intestine. Each capsule delivers magnesium in this form together with vitamin B6, which contributes to normal nervous system function and energy metabolism. The product comes in a 60-capsule pack; the exact amount of elemental magnesium per capsule is listed on the label. Because absorption can vary between individuals, consistent daily use with a meal is the typical approach people take to maintain steady levels.
