Overview

Magnesium hydroxide is primarily used as a laxative due to its limited absorption and strong osmotic effects in the intestines. Despite magnesium's importance for overall health, magnesium hydroxide is not ideal for supplementation due to poor bioavailability. Consequently, the primary effect is on digestive function, not systemic magnesium levels. The laxative effect makes it difficult to maintain consistent magnesium levels.
