Vitamin D & Mortality Risk

Does vitamin D affect lifespan?

Yes. Low vitamin D levels are associated with increased mortality, particularly from cardiovascular disease and cancer.

Explanation

Vitamin D influences calcium balance, bone metabolism, immune defense, and gene transcription. Large meta-analyses show higher mortality in individuals with deficient vitamin D status, with risks especially high for cardiovascular and cancer outcomes. Supplementation in deficient populations improves fracture prevention, reduces infection incidence, and may reduce cancer mortality.

Vitamin D deficiency is common, particularly in older adults and those with limited sun exposure. Since optimal serum levels vary individually, blood testing is essential to personalize supplementation.

Practical Emphasis: Test your vitamin D status, particularly if you live in northern latitudes, have darker skin, or spend little time outdoors. Supplement only as needed to maintain sufficiency, since excess vitamin D can cause harm.

Takeaway (Action Tip)

Ask your doctor to check your 25-hydroxyvitamin D levels and correct deficiencies.
