What is Doctor’s Best Bone Maker with Bonolive? Doctor’s Best Bone Maker with Bonolive is a calcium-free bone health supplement that helps promote the stimulation of bone building cells (osteoblasts). Bonolive is the only clinically proven olive-based bone supplement. The clinical dose is very small compared to other calcium supplements. Bone Maker contains olive leaf extract standardized to 40% oleuropein versus typical olive leaf extracts which only contain 20%. Oleuropein works in support of two fundamental bone health goals: promoting bone formation and supporting bone strength.
