What Is Magnesium L-Threonate?
Magnesium is an essential mineral involved in over 600 processes in the body, but not all forms are absorbed equally well. Magnesium L-Threonate is created by combining magnesium with threonic acid, a metabolite of vitamin C, resulting in one of the most bioavailable forms of magnesium available. It's particularly notable for its ability to cross into the brain, where research suggests it may support relaxed focus, mood enhancement, and improved cognitive performance, making Mag3 a popular choice for those wanting cognitive and mood support alongside the everyday benefits of magnesium.
