Vitamin D

Vitamin D levels do not significantly impact mortality risk.

Recent studies show that varying levels of vitamin D or supplementation do not significantly affect all-cause mortality. While vitamin D is crucial for bone health, immune function, muscle function, and cell growth, its role in reducing mortality risk remains unclear. Meta-analyses and large-scale trials like the VITAL study have found no significant difference in mortality between those taking vitamin D supplements and control groups. Deficiency in vitamin D may affect health, but supplementing it does not appear to reduce mortality risk in the general population. More comprehensive research is needed to fully understand its effects on overall health.
