Magnesium citrate is magnesium bound to citric acid, forming one of the most bioavailable and widely used magnesium supplements. It's commonly taken for general magnesium supplementation, muscle relaxation, and digestive regularity — citrate has a mild osmotic laxative effect at higher doses. Labels typically show two numbers: the elemental magnesium content (what your body absorbs) and the total compound weight (which includes the citric acid). For example, a product listing "Magnesium (as Magnesium Citrate) 150 mg" provides 150mg of elemental magnesium from a larger amount of the citrate compound. This page compares products by the elemental magnesium content — the number that matters for your daily intake. Products below are ranked by cost at your chosen daily dose.
