Micronutrients & recovery
Calcium and vitamin D supplementation (1,000 mg/400 IU) is associated with a modest reduction in urinary tract stone risk in adherent users, though the overall risk increase is small (HR 1.17).
Taking 1,000 mg of calcium and 400 IU of vitamin D3 daily slightly increases your risk of developing kidney stones (from 0.30% to 0.35% over 7 years). If you are prone to stones, discuss this with your doctor. However, for most women, this small risk is balanced by the significant benefit of reduced hip fracture risk.
