Micronutrients & recovery
Low circulating levels of 25-hydroxyvitamin D are associated with a significantly higher risk of death from cardiovascular disease, cancer, and all-cause mortality in observational studies.
Maintaining adequate vitamin D levels is associated with a lower risk of death from heart disease and cancer. While this is an observational finding, ensuring sufficient levels through sensible sun exposure or supplementation is a low-risk strategy for long-term health.
pooled relative risks were 1.35 (95% confidence interval 1.13 to 1.61) for death from cardiovascular disease, 1.14 (1.01 to 1.29) for death from cancer... and 1.35 (1.22 to 1.49) for all cause mortality.
Why this rating
Observational studies are prone to confounding (lifestyle, socioeconomic status), though the sample size is massive.
