Magnesium taurate is a complex made of magnesium and an amino acid, taurine—two components with health benefits. Magnesium regulates muscle contraction and maintains electrolyte balance in the body's tissues. It is also involved in bone development and the breakdown of sugars, fats, and protein. Magnesium taurate has been studied in animal models to treat eye injuries, traumatic brain injury (TBI), and high blood pressure, but human clinical trials are needed to verify its effects.
