Boron Interactions

Boron reduces urinary calcium excretion and supports the hydroxylation of vitamin D into its active form, which in turn enhances intestinal calcium absorption. Postmenopausal women taking 3 mg/day of boron have shown reduced urinary calcium loss and improved markers of calcium retention.

Boron supports magnesium retention and deposition in bone, and the two minerals jointly influence the activation of vitamin D. In rodent studies, boron supplementation reduced the metabolic abnormalities of magnesium-deficient diets and raised plasma magnesium levels.
