Though the body requires a certain amount of daily calcium to function normally, with so many different types of calcium, it can be difficult to decide which form is the right one to take. Calcium aspartate, the result of binding L-aspartic acid with calcium, creates a stable bond that transforms the calcium into a form the body can easily recognize and use. The result is an unprecedented absorption rate. Make the most of the calcium you take with Swanson Premium Calcium Aspartate.
