Micronutrients & recovery
Calcium supplementation reduces fracture risk in populations with low baseline calcium intake, but provides no additional skeletal benefit or fracture reduction in populations with adequate or high customary intake.
If you do not consume enough calcium-rich foods (like dairy, fortified alternatives, or leafy greens) to reach about 400-500 mg per day, supplementation can help reduce your risk of hip fractures. However, if you already eat a diet rich in calcium, adding more supplements will not further protect your bones or reduce fracture risk. Focus on dietary sources first.
Taken together, the data suggest that, in populations at risk of osteoporotic fracture, there is a threshold of increasing risk below around 400– 500 mg/d but that, at a population level, no additional benefit is associated with a customary intake above those currently recommended.
Why this rating
The paper cites multiple meta-analyses and cohort studies, noting that while individual study results vary, the aggregate data supports a threshold effect.
