Magnesium Hydroxide is widely used as an active pharmaceutical ingredient (API) in tablet or suspension form to support magnesium intake and manage digestive health.
In pharmaceutical applications, magnesium hydroxide functions both as an antacid and as a gentle osmotic laxative. As an antacid, it neutralizes excess gastric acid, providing fast and effective relief from heartburn, acid indigestion, and upset stomach. When used in higher doses, it acts as an osmotic laxative by attracting water into the intestines, which softens the stool and promotes natural bowel movements.
Magnesium hydroxide is considered well-tolerated and effective, especially for short-term use. Appropriate dosing is important to avoid side effects such as diarrhea or electrolyte imbalances, particularly in individuals with compromised kidney function.
The high elemental Magnesium content of Magnesium Hydroxide makes it a useful source of magnesium in food supplements, supporting adequate intake. However, its low solubility in water means it is absorbed more slowly than other forms, such as magnesium citrate or glycinate. For this reason, it is often combined with other magnesium salts to optimize overall magnesium uptake.
Magnesium hydroxide is permitted as source of Magnesium in all types of foods. It is found in various food products, such as protein drinks, bars, meal replacements and other nutritional powder formula. Magnesium hydroxide functions as an acidity regulator and anti-caking agent and is approved as food additive under E-number 528.
