Bone Up by Jarrow Formulas: Review
Best for: bone-density support alongside joint health
One-line takeaway: A bone-density formula that complements joint supplementation — calcium, vitamin K2 (MK-7), vitamin D3, and magnesium in the proportions modern bone-health research has shifted toward.
What it is
Jarrow Formulas Bone-Up provides calcium hydroxyapatite (a whole-bone-derived calcium), vitamin K2 as MK-7, vitamin D3, magnesium, and supporting cofactors. Designed for bone-mineral-density support, useful alongside knee-joint supplements when osteopenia or osteoporosis is in the picture.
Key features
- Calcium as microcrystalline hydroxyapatite (whole-bone-derived)
- Vitamin K2 as MK-7 — the form supported by recent bone-health research
- Vitamin D3 (cholecalciferol) for calcium uptake
- Magnesium and zinc as bone-mineralisation cofactors
- 240-capsule bottle, 60-day supply at four-per-day dose
Who it’s for
This product fits buyers who match this profile:
- Have been told you have low bone density (osteopenia or osteoporosis)
- Want a bone-mineral formula alongside your joint supplements rather than instead of
- Prefer whole-bone-derived calcium rather than calcium carbonate
