AOR Advanced Bone Protection - Contains MBP, an active protein complex from the whey fraction of milk. Research suggests that MBP can positively impact bone health by reducing bone loss (re-absorption) and increasing bone mineral density. Advanced Bone Protection is not a source of calcium, but rather a beneficial adjunct to any calcium-based bone health regimen for those who are at risk of developing, or already suffering from, osteoporosis.  It can also be used to support bone healing after sustaining a fracture.
