Microcrystalline hydroxyapatite concentrate (MCHC) is a calcium supplement made from bovine bone. It provides calcium in a mineral matrix similar to human bone, along with small amounts of phosphorus and other trace minerals naturally present in bone tissue.
People take MCHC to support bone health. Its calcium form matches bone mineral, so the body may use it efficiently for bone maintenance. Take MCHC with meals. Adequate vitamin D helps absorb the calcium and phosphorus it supplies.
Calcium supplements, including MCHC, can cause high blood calcium (hypercalcemia) and raise the risk of kidney stones in some individuals. MCHC may interact with thiazide diuretics, bisphosphonates, tetracycline antibiotics, and iron supplements. If you have kidney disease, a history of kidney stones, or hypercalcemia, consult a healthcare provider before using calcium supplements. This product comes from bovine bone. Check the source if you have concerns about bovine spongiform encephalopathy (BSE) or dietary restrictions.
