Magnesium L-threonate is the salt formed from mixing magnesium and threonic acid, a water-soluble substance derived from the metabolic breakdown of vitamin C.
This form is easily absorbed. Animal research notes that it may be the most effective type for increasing magnesium concentrations in brain cells.
Magnesium L-threonate is often used for its potential brain benefits and may help manage certain brain disorders, such as depression and age-related memory loss. Nonetheless, more research is needed.
