Excess Caffeine (Coffee, Energy Drinks)
Excessive caffeine intake increases calcium loss and may impair bone cell activity, especially when calcium intake is low.
Bone repair depends on calcium balance and osteoblast function. High caffeine intake undermines both during healing.
While moderate caffeine intake is generally safe, excessive caffeine can hinder bone healing. High caffeine intake increases urinary calcium excretion and may reduce intestinal calcium absorption. Experimental studies also suggest caffeine can inhibit osteoblast proliferation and collagen synthesis. Epidemiological studies associate very high caffeine intake with increased bone loss and fracture risk, particularly in individuals with low calcium intake. Animal studies demonstrate delayed bone regeneration with high-dose caffeine exposure. During bone healing, limiting caffeine to moderate levels supports calcium retention and bone formation.
