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 in formulations requiring a soluble and well-tolerated magnesium source. It serves critical functions across the pharmaceutical, nutraceutical, and food industries, where consistent quality and reliable supply are paramount for product efficacy and safety.

Application

• Pharmaceutical & Nutraceutical Formulations: A key active ingredient in magnesium supplements, antacids, and laxatives, valued for its bioavailability and gentle action.
• Food & Beverage Fortification: Used as a nutritional additive to fortify beverages, dairy products, and functional foods with essential magnesium.
• Dietary Supplements: A preferred source of magnesium in capsule, tablet, and powder formulations due to its high solubility and absorption.
• Cosmetic & Personal Care: Incorporated into skincare products for its purported skin-conditioning and anti-inflammatory properties.
• Industrial Applications: Acts as a buffering agent, sequestrant, or stabilizer in various chemical processes and specialty formulations.
