Bone-Up

Uses OHC calcium (actual bone matrix with collagen and growth factors) instead of cheap calcium carbonate. D3+K2 directs calcium to bones. Magnesium for mineralization. The most biochemically complete bone supplement. Six capsules though.

7.5/10

Whensplit doses

Split calcium across 2-3 doses for better absorption (max 500mg at once).

Foodwith food

Calcium absorbs better with food, especially meals with some fat.

SafetyAll clear

High calcium. Don't combine with other calcium supplements. Take with food.

ResearchStrong evidence

OHC vs calcium carbonate has comparative studies. D3+K2+Mg for bones is well-established.

What We Like

  • OHC calcium contains the entire bone matrix (collagen, phosphorus, growth factors), not just calcium.
  • D3+K2 MK-7 directs calcium to bones.
  • Magnesium at 500mg for bone mineralization.
  • Vitamin C for collagen synthesis.

Watch Out For

  • 6 capsules per serving is a lot.
  • Magnesium as oxide+citrate blend (some oxide).
  • Calcium at 1000mg is high (modern research suggests 500mg may be sufficient).
