Jarrow Formulas Bone-Up Superior Calcium
by Jarrow Formulas
"Microcrystalline hydroxyapatite calcium with MK-7 and D3 — the bone-identical calcium form for superior bone density support"
Overview
Jarrow Formulas Bone-Up provides calcium as microcrystalline hydroxyapatite (MCHA), the same form of calcium found in human bones. MCHA naturally contains calcium, phosphorus, and the organic bone matrix including type I collagen, osteocalcin, and growth factors. This is fundamentally different from calcium carbonate or citrate — it provides the complete bone mineral complex. The formula adds vitamin D3 (1000 IU), vitamin K2 as MK-7 (45mcg), and vitamin C for collagen synthesis.
