Micronutrients & recovery
Dietary calcium and vitamin D are inversely associated with hypertension risk, but calcium and vitamin D supplements do not significantly reduce this risk.
Do not rely on calcium or vitamin D supplements to prevent high blood pressure. Instead, focus on dietary sources, specifically low-fat dairy products, which provide these nutrients in a form associated with reduced hypertension risk.
GoodQualifiesHIGH confidence
The risk of hypertension decreased in the higher quintiles of dietary calcium (multivariate relative risk in the highest quintile: 0.87) and dietary vitamin D (multivariate relative risk in the highest quintile: 0.95), but did not change with calcium or vitamin D supplements.
Why this rating
Same large cohort study; observational data for supplements.
