Collagen's Crucial Role In Your Total Bone Health The National Institutes of Health reports that it takes both calcium and collagen to build strong healthy bones. Collagen makes up 30% of your bone. Collagen serves as the "binding sites" for calcium and gives bone the pliability it needs to withstand physical stress. Age-related diminution of collagen leads to brittle bones and low BMD. The ch-OSA in Collagenizer ULTRA increases bone collagen formation and increases BMD. The choline and inositol help maintain "osteo-balance," ensuring proper renewal of bone. The MK7 makes sure calcium gets delivered to the bone site. Vitamin B12 together with choline protects against collagen breakdown.

Insufficient Bone Collagen Insufficient calcium "binding sites," low BMD brittle bone and "holes" in bone (osteoporosis) Optimal Bone Collagen Optimal calcium "binding sites," optimum BMD, strong, pliable with the ability to bend-not-break Measured at the hip
