Overview
This magnesium glycinate tablet delivers 400mg per dose in a 200-count bottle, a non-buffered bisglycinate form marketed for sleep, leg cramps and muscle relaxation.
Glycinate tends to be better tolerated by the digestive tract than magnesium oxide, since it's bound to the amino acid glycine rather than acting like a laxative-style compound. The 200-tablet count is one of the larger bottles in this category, stretching well past a typical month.

Who it's for
