Best forYou want a vegan hydroxyapatite calcium formula paired with D3 and K2 rather than a basic calcium pill.

Overview

OsteoMD, from 1MD Nutrition, uses hydroxyapatite, a bone-mineral form of calcium, combined with vitamin D3 and K2 in a 90-capsule vegan formula marketed for bone density support in both women and men.

Hydroxyapatite is a different calcium delivery form than the calcium carbonate or citrate found in cheaper supplements. Pairing it with D3 and K2 follows the common logic that D3 helps calcium absorption while K2 helps direct that calcium toward bone. This one is marketed to both sexes, rather than the women-only framing common in bone supplements.

  • Hydroxyapatite calcium with vitamin D3 and K2
  • 90 vegan capsules per bottle
  • Marketed for bone and joint support
  • For both women and men

Who it's for

Adults, men and women, looking for a calcium and D3-K2 combination aimed at bone support. Not the choice for someone who just wants the cheapest plain calcium pill.
