Thorne Magnesium Bisglycinate
by Thorne
"Practitioner-grade magnesium glycinate — NSF Certified for Sport with superior absorption and zero GI distress"
Overview
Thorne Magnesium Bisglycinate provides 200mg of magnesium chelated to glycine in Thorne's practitioner-grade formulation. The bisglycinate chelate is the gold standard for magnesium absorption — the glycine amino acid carrier facilitates intestinal uptake through amino acid transport pathways rather than competing with other minerals for absorption. This form is also the gentlest on the GI tract, making it ideal for those who experience loose stools with magnesium oxide or citrate. Thorne is trusted by Mayo Clinic, Cleveland Clinic, and U.S. Olympic teams.
