* Value Size * Microcrystalline Hydroxyapatite * Potassium Citrate & Natural MK-7 * Now with More Vitamin K2 * Up-Formulated * Gluten Free * Promotes Bone Density * Dietary Supplement Bone-Up provides ossein hydroxyapatite complex (OHC) (from free-range Australian/New Zealand calves), which includes the superior combination of the inorganic calcium lattice of microcrystalline hydroxyapatite (MCHA) with an organic protein milieu. The OHC is combined with vitamin D3 and vitamin K2 as MK-7 from natural fermentation (a more bioavailable form of vitamin K) to support the deposition of calcium into the bones as well as to assist in building up the organic bone matrix. Potassium citrate is also added for optimal osteo support. Health Claim: Adequate calcium and vitamin D as part of a healthful diet, along with physical activity, may reduce the risk of osteoporosis later in life.
