Not all magnesium compounds are equal. Some contain more elemental magnesium, while others are more bio-available. Magnesium Citrate provides the perfect balance of both more bio-availability and high elemental magnesium content. Magnesium Citrate is the most bio-available of the common supplement options, allowing easier and faster absorption into your body. As a citrate, Magnesium is readily absorbed into the bloodstream via the pyruvate cycle.

    Cramp relief

    Bought this to help with awful leg cramps at night. So far so good. I take one a night before bed and each capsule is 300mg. They’re quite large but easy to swallow.
