magnesium bisglycinate

Magnesium bisglycinate is a **chelated form of magnesium** where each magnesium ion is bound to two molecules of the amino acid glycine, enhancing its stability and gastrointestinal absorption[2][3][5]. This chelation markedly improves magnesium’s bioavailability and reduces the risk of diarrhea compared to other magnesium salt forms such as oxide or citrate[1][4]. Magnesium is a cofactor in over 300 enzymatic reactions critical for energy production, muscle contraction, nerve signal transmission, blood pressure regulation, bone health, and more[1][2][4][5]. The glycine component also provides calming effects and further supports nervous system function[1][2]. Magnesium bisglycinate is primarily used to correct or prevent magnesium deficiency, support muscle function, improve sleep and stress resilience, aid cardiovascular and bone health, and relieve symptoms such as muscle cramps, migraines, or PMS[4][5].
