Micronutrients & recovery
Low baseline Vitamin D status (25(OH)D concentration) is associated with a higher risk of developing hypertension and cardiovascular disease in observational studies, but this association does not translate to benefit from supplementation.
Having low Vitamin D levels is a marker of higher risk for heart issues and high blood pressure, but simply taking Vitamin D supplements does not reduce that risk. Focus on overall health markers rather than just correcting Vitamin D levels for heart health.
LimitedQualifiesMEDIUM confidence
In meta-analysis of 3 cohorts, lower 25-hydroxyvitamin D concentration was associated with incident hypertension (relative risk, 1.8 [95% CI, 1.3 to 2.4]).
Why this rating
Based on meta-analysis of observational cohorts, which are prone to confounding.
