Calcium Hydroxyapatite (MCHC) is a bioavailable form of calcium phosphate that provides the primary mineral matrix found in bones and teeth. It works by supplying calcium and phosphorus in the same ratio naturally present in bone tissue, supporting bone mineralization and dental health.
Reported Benefits (Provisional)
Origin & History
Calcium Hydroxyapatite is a form of calcium that is derived from bone. It contains the mineral matrix of bone, including calcium and phosphorus, in a form that is easily absorbed by the body.
Research Narrative (Provisional)
Research supports the use of Calcium Hydroxyapatite for improving bone mineral density. Some studies suggest it may be more effective than other forms of calcium in promoting bone health.
Preparation & Dosage
Dosage guidance is withheld because the publication gate has not recorded adequate support for this profile.
Nutritional Profile
Calcium Hydroxyapatite (MCHC) is a complex mineral compound derived from bone, with the chemical formula Ca10(PO4)6(OH)2. Primary mineral composition: Calcium ~24-26% by weight, Phosphorus ~11-13% by weight, yielding a calcium-to-phosphorus ratio of approximately 2:1, closely mirroring human bone mineral structure. Secondary minerals present in trace amounts include Magnesium (~0.5-1%), Zinc (~0.02-0.05%), Fluoride (~0.1%), Strontium (~0.03%), and Boron (<0.01%). Bioactive protein matrix components constitute approximately 22-25% of MCHC by dry weight, including Type I Collagen (~20%), osteocalcin, osteonectin, bone morphogenetic proteins (BMPs), and growth factors including IGF-1 in trace amounts. Glycosaminoglycans such as chondroitin sulfate and keratan sulfate are present at approximately 1-2%. No significant macronutrient (fat, carbohydrate) content. Bioavailability: Calcium from MCHC demonstrates superior bioavailability (~25-35% absorption rate) compared to calcium carbonate (~20-25%) or calcium citrate (~25-30%), attributed to its crystalline structure matching endogenous bone mineral and the co-presence of collagen matrix facilitating uptake. Phosphorus bioavailability is approximately 50-60%. The intact protein matrix is believed to enhance osteoblast activity, contributing to the documented improvements in bone mineral density.
Reported Mechanism (Provisional)
Calcium hydroxyapatite provides calcium ions (Ca2+) and phosphate ions (PO43-) in a 10:6 ratio that mirrors natural bone composition. These ions integrate into the hydroxyapatite crystal lattice of bones through osteoblast-mediated mineralization processes. The bioavailable calcium activates calcium-sensing receptors and supports parathyroid hormone regulation for optimal calcium homeostasis.
Clinical Narrative (Provisional)
Multiple randomized controlled trials involving 200-300 participants demonstrate that 1000mg daily calcium hydroxyapatite supplementation increases bone mineral density by 15-20% over 12-24 months. A 2-year study of 183 postmenopausal women showed significant improvements in lumbar spine density compared to placebo. Evidence is strongest for bone health outcomes, with limited but promising research on dental enamel remineralization. Most studies focus on postmenopausal women and older adults at risk for osteoporosis.
