KAL Magnesium Taurate is magnesium chelated with the amino acid taurine, designed to create a powerhouse, bioavailable form of magnesium. Taken regularly, magnesium taurate may offer targeted support for cardiovascular and nerve health, as well as healthy muscle function, including one of your hardest-working muscles—your heart. The "Plus" in our formula is co-enzyme vitamin B-6, which is thought to work synergistically with magnesium and may help support the formation of red blood cells and a calm, healthy nervous system.
