Increase bone density

What this outcome means

Bone mineral density is how much mineral is packed into your bones, a core gauge of their strength and resistance to fracture. On DoseRank it maps to a defined health outcome built from human studies on DEXA scan T-scores, bone mineral content, and fracture-risk measures – data sourced from open sources and specialized resources. DoseRank is not medical advice.

Who it's for

Postmenopausal womenBone loss that often accelerates after estrogen declines.

Older menAging skeletons quietly thinning well before any fracture.

Fracture historyPeople who have already broken a bone from a minor fall.

Stack buildersAlready taking supplements such as Vitamin D3 (Cholecalciferol) or Calcium Carbonate and want the dose right.

Evidence level

88Strong

Vitamin D3 (Cholecalciferol) and Calcium Carbonate – have strong public evidence. DoseRank looks at both evidence quality and formula fit.
