Three Sources of Magnesium

Our Triple Source formula combines three different magnesium sources, each selected to provide a well-rounded approach to daily magnesium supplementation:

• Aquamin® Magnesium — A marine-derived mineral source obtained from seawater. In addition to magnesium, Aquamin® naturally provides a spectrum of trace minerals from its marine source.

• Magnesium Citrate — Magnesium bound to citric acid. Magnesium citrate is a commonly used form of supplemental magnesium and is generally well absorbed. At higher amounts, magnesium citrate may also have a mild laxative effect.

• Magnesium Amino Acid Chelate — Magnesium complexed with a full spectrum of amino acids derived from rice protein. This chelated form provides another source of magnesium to complement the citrate and marine-derived magnesium in the formula.

Together, these three sources provide 400 mg of elemental magnesium per 4-tablet serving to help support healthy muscle and nerve function, energy production, and overall wellness.*
