Doctor's Best High Absorption Magnesium promotes restful sleep and muscle relaxation.* Approximately seventy-five percent of Americans are deficient in magnesium. Doctor's Best specially chelates their magnesium with natural amino acids, which makes their products water soluble and therefore easier for the body to absorb.* Doctor's Best chelated magnesium is so effective, your body absorbs it six times faster than other forms of magnesium.* Gentle on the stomach, magnesium lysinate glycinate chelate does not cause gastric distress like other magnesium varieties do.*.
