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 sources. This compound is essential for formulating high-quality nutritional supplements and functional foods aimed at addressing magnesium deficiency. 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: As a primary source of elemental magnesium in capsules, tablets, and powder formulations for bone health, muscle function, and energy metabolism support.
• Pharmaceutical Preparations: Used as an active pharmaceutical ingredient (API) in laxatives and electrolyte replenishment solutions.
• Functional Food & Beverage Fortification: For enriching sports drinks, meal replacements, and health-focused food products with bioavailable magnesium.
• Cosmetic & Personal Care: Incorporated into skincare products for its potential skin-soothing and anti-inflammatory properties.
• Industrial Applications: Acts as a buffering agent, sequestrant, or stabilizer in certain chemical processes and formulations.
