Activating GPR133 May Rebuild Bone in Osteoporosis

New research shows that activating the GPR133 receptor with the compound AP503 boosts osteoblast-driven bone formation, dramatically increasing bone density and strength in osteoporotic mice and even stronger when combined with exercise; the approach could shift osteoporosis treatment from slowing bone loss to rebuilding bone, but it remains early-stage animal research with no human trials yet.
