OsteoMedica - 120c By NuMedica | MCHC Bone Support | OsteoMedica™ provides MCHC (microcrystalline hydroxyapatite concentrate) from New Zealand open-range, pasture-fed cattle raised in pesticide-free environments. Cold-processing technology preserves the delicate organic factors that heat and solvents destroy. The MCHC in OsteoMedica™is a full-spectrum, highly-absorbable crystalline compound composed of calcium, phosphorus, organic factors, collagen (type 1) and an active protein matrix, along with its naturally occurring bone growth factors. 30 years of research has documented its benefit in optimal bone health. OsteoMedica™ also contains Magnesium and Vitamin D to provide a comprehensive bone support formula. The Vitamin D stimulates intestinal calcium absorption and helps regulate calcium and phosphorus homeostasis in the body. Click "Ingredient" tab above for more information.
