Description

Magnesium Citrate is a highly bioavailable organic salt of magnesium and citric acid, widely recognized for its superior absorption profile compared to inorganic magnesium salts. This compound is essential for formulating high-quality nutritional supplements and functional foods aimed at supporting bone health, muscle function, and energy metabolism. It serves as a critical ingredient for manufacturers in the pharmaceutical, nutraceutical, and food & beverage industries seeking a reliable and effective magnesium source.

Application

• Dietary Supplements & Nutraceuticals: A primary source of elemental magnesium in capsules, tablets, and powdered drink mixes for bone support and electrolyte balance.
• Pharmaceutical Preparations: Used as an active pharmaceutical ingredient (API) in laxatives and magnesium deficiency treatments.
• Food & Beverage Fortification: Incorporated into functional foods, sports drinks, and meal replacement shakes as a nutritional fortificant.
• Cosmetic & Personal Care: Acts as a pH buffer and skin-conditioning agent in lotions, creams, and deodorants.
• Industrial Applications: Serves as a catalyst or buffering agent in certain chemical synthesis processes.
