DESC: Ultra Bone-Up by Jarrow Ultra Bone-Up& combines Glucosamine and MSM (to support the synthesis of glycosaminoglycans that compose the organic matrix of bone tissue) with Microcrystalline Hydroxyapatite (MCHA) calcium, from free range Australian calves. Also added are the nutrients MK-7 (an advanced form of Vitamin K2), SDG Lignans from flaxseed, Methyl B12 and Curcumin for optimal osteo support. Health Claim: In conjunction with regular, weight bearing exercise and a healthy diet, calcium helps teen and young adult women build bone mass and maintain bone health, and may reduce their risk of osteoporosis later in life. Daily calcium intake above 2,000 mg is not likely to provide additional benefit. Adequate calcium intake is also linked to reduced osteoporosis by slowing bone loss in older men and women.* For best results use with Jarrow FORMULAS& BioSil™, the Biologically Active Silicon.
