Micronutrients & recovery
Higher compliance rates and higher doses of calcium (≥1200 mg) and vitamin D (≥800 IU) significantly increase the fracture risk reduction.
To get the most benefit, aim for at least 1200 mg of calcium and 800 IU of vitamin D daily. Taking these doses consistently is more effective than taking lower doses irregularly.
StrongQualifiesHIGH confidence
The reduction in fracture risk was significantly greater (by 24%) in trials with high compliance rates. A more substantial treatment effect was noted with calcium doses of 1200 or more than with lower doses... and with vitamin D doses of at least 800 IU
Why this rating
Based on the same robust meta-analysis.
