M.C.H.C. Calcium — Microcrystalline Hydroxyapatite & Calcium Citrate with Bone Matrix Cofactors for Comprehensive Skeletal Support
M.C.H.C. Calcium is a premium bone support formula built around a distinctive calcium complex: a 48% microcrystalline hydroxyapatite (MCHC) / 52% calcium citrate blend — combining the bone-matrix richness of whole-bone MCHC with the bioavailability advantages of calcium citrate. Supported by Vitamin K1 and a full panel of bone-relevant trace minerals in bioavailable aspartate and citrate forms.*
Serving size is 2 vegetarian capsules, 60 servings per container (120 capsules).
What's inside and why it matters
Vitamin K1 as Phytonadione (80mcg, 67% DV) — Vitamin K1 is essential for the normal carboxylation of osteocalcin — the primary non-collagen bone protein that binds calcium within the bone matrix. Without adequate Vitamin K, osteocalcin cannot be properly activated and calcium cannot be effectively incorporated into bone mineral. Vitamin K1 provides foundational support for normal calcium utilisation within bone.*
Calcium as 48% Microcrystalline Hydroxyapatite (MCHC) / 52% Calcium Citrate (200mg, 15% DV)
This is the defining ingredient of M.C.H.C. Calcium — a sophisticated calcium blend combining two of the most bioavailable and functionally complete calcium forms available:
Microcrystalline Hydroxyapatite (MCHC, 48% of calcium blend) — MCHC is a whole-bone concentrate derived from bovine bone, providing calcium in the same crystalline hydroxyapatite form found naturally in human bone. Unlike isolated calcium salts, MCHC provides the complete bone matrix: calcium phosphate in hydroxyapatite crystal structure, naturally occurring bone protein fractions, collagen peptides, glycosaminoglycans (including chondroitin sulphate), and naturally occurring bone growth factors. MCHC provides the full biological context of bone mineral — not just isolated calcium.*
Research on MCHC consistently demonstrates superior bioavailability and bone-supportive activity compared to calcium carbonate, reflecting the fact that the body recognises and utilises the naturally occurring hydroxyapatite structure more effectively than synthetic calcium salts.*
Calcium Citrate (52% of calcium blend) — Calcium citrate is one of the most bioavailable isolated calcium forms — unlike calcium carbonate, it does not require stomach acid for absorption and is equally well absorbed with or without food. The combination of MCHC (for bone matrix completeness) and calcium citrate (for bioavailability) creates a calcium complex that is both structurally appropriate for bone and highly bioavailable.*
Phosphorus as Monosodium Phosphate (13mg, 1% DV) — Phosphorus is the second most abundant mineral in bone after calcium, with the normal calcium-to-phosphorus ratio in bone hydroxyapatite being approximately 2:1. This phosphorus contribution reflects the naturally occurring phosphorus in the whole-bone MCHC matrix.*
Magnesium as Magnesium Aspartate (8mg, 2% DV) — A highly bioavailable organic form providing cofactor support for normal bone metabolism, Vitamin D activation, and normal osteoblast function.*
Zinc as Zinc Aspartate (8mg, 73% DV) — Zinc aspartate at 73% of the daily value. Zinc is an essential cofactor for the enzymes involved in normal bone matrix synthesis — particularly for the normal activity of alkaline phosphatase (involved in bone mineralisation) and for normal osteoblast differentiation and function.*
Manganese as Manganese Aspartate (8mg, 348% DV) — A high-potency manganese dose at 348% of the daily value in aspartate form. Manganese is a critical cofactor for glycosyltransferases — the enzymes responsible for normal glycosaminoglycan synthesis within the bone and cartilage matrix. Since MCHC naturally contains glycosaminoglycans, the inclusion of manganese at this level directly supports normal organic matrix synthesis.*
Potassium as Potassium Aspartate (8mg, <1% DV) — Contributing to normal electrolyte balance and healthy alkaline mineral buffering — relevant to bone health given the well-established relationship between dietary acid load and urinary calcium excretion.*
Boron as Boric Acid Aspartate (38mcg) — A trace dose of boron in aspartate form. Boron plays a regulatory role in the normal metabolism of calcium, magnesium, and Vitamin D, and in the normal activity of steroid hormones involved in bone metabolism. Supports normal calcium and magnesium retention in bone.*
Silicon as Silicon Dioxide Aspartate (1mcg) — Trace silicon supports normal collagen synthesis and normal bone matrix formation. Silicon is required for normal integrity of the organic bone matrix at the earliest stages of bone development.*
Why MCHC rather than standard calcium?
Standard calcium supplements provide isolated calcium salts — carbonate, citrate, or malate. MCHC provides calcium in the same structural form found in bone — hydroxyapatite — along with the complete bone matrix: protein, collagen, glycosaminoglycans, and naturally occurring growth factors. The 48/52% MCHC-citrate blend in M.C.H.C. Calcium combines the structural completeness of whole-bone MCHC with the superior bioavailability and acid-independent absorption of calcium citrate.*
