Magnesium Citrate

About

Last Updated: Friday 14th August 2026 Magnesium citrate is magnesium bound to citric acid. It is one of the most widely used organic forms of magnesium and is more readily absorbed than inorganic forms such as magnesium oxide, which is why it appears in a large number of magnesium supplements and blends. Magnesium supports normal muscle contraction and relaxation, nerve function, and energy metabolism. It also helps reduce the occurrence of muscle cramps and mild spasms when dietary magnesium intake is inadequate. Because magnesium is lost through sweat, requirements go up with training volume, which makes citrate a common addition to a recovery routine. Why Choose Magnesium Citrate Well absorbed – An organic form of magnesium that is more readily absorbed than magnesium oxide. Muscle support – Commonly chosen to support healthy muscle function and help relieve cramps when dietary intake falls short. Mixes easily – Citrate is a popular choice in powders, making it straightforward to take a higher dose in water or a shake. Flexible dosing – Available in both capsules and powders, so you can adjust intake to suit your needs. Widely studied – One of the better-researched organic forms of magnesium in the context of absorption and exercise. Magnesium Citrate or Magnesium Glycinate Both are well-absorbed organic forms and either will do the job for general daily use. Citrate is the more established option for muscle support and cramp relief, and it is the form most often found in higher-dose powders. Glycinate is typically chosen by anyone with a sensitive stomach or for evening use, since it is the gentler of the two on digestion and does not carry the same mild laxative effect at higher doses.
