Summarized by Masters of Longevity from Aging Cell.
Vitamin D’s role in later-life health is examined through longitudinal cohort data, offering readers a clear preview of an epidemiological study on deficiency, supplementation, and aging outcomes.

Key Takeaways
- Lower baseline vitamin D levels were associated with higher incidence of aging-related morbidity during follow-up in both cohorts.
- Vitamin D supplementation correlated with reduced all-cause mortality after adjusting for major confounders in pooled analyses.
- Effect sizes varied by age and baseline deficiency status, with stronger associations observed in older and deficient subgroups.
