Chelated Magnesium vs. Magnesium Citrate: What's the Difference?

Edited by Aimie Carlson || By Harlon Moss || Published on January 4, 2024
Chelated magnesium is magnesium bound to organic molecules for better absorption, while magnesium citrate combines magnesium with citric acid, often used for its laxative effect.

Key Differences

Chelated magnesium refers to magnesium ions that are chemically bonded to amino acids or other organic agents to enhance absorption and bioavailability. Magnesium citrate is a compound formed by combining magnesium with citric acid, which improves its solubility and absorption but is primarily known for its laxative properties.
The chelation process in chelated magnesium improves its stability and absorption in the digestive tract, making it a preferred choice for dietary supplements aimed at increasing magnesium levels. Magnesium citrate, while also well-absorbed, is often used for its ability to draw water into the intestines, aiding in bowel movements.
Chelated magnesium is often used to address magnesium deficiencies, support muscle and nerve function, and contribute to bone health. Magnesium citrate, aside from its use as a laxative, can also help with magnesium supplementation but is more commonly used for bowel preparation prior to medical procedures.
Due to its enhanced absorption, chelated magnesium is generally well-tolerated and less likely to cause gastrointestinal side effects. Magnesium citrate, though effective, can lead to dehydration and electrolyte imbalances if used excessively as a laxative.
Chelated magnesium is available in various forms, such as magnesium glycinate or magnesium taurate, each with specific health benefits. Magnesium citrate is typically found in over-the-counter products for constipation relief and is also available in liquid and pill forms.
