How it works

Strong evidence supports calcium for maintaining bone mineral density, particularly in postmenopausal women and older adults. Its role in fracture prevention is most effective when combined with Vitamin D.

Acts as a structural component of the hydroxyapatite bone matrix and as a secondary messenger in muscle contraction and nerve impulse transmission.

Safety

  • May increase risk of kidney stones in susceptible individuals.
  • Excessive supplemental intake is linked to vascular calcification.
  • Can cause constipation and bloating.
