Where things stand
Vitamin D has an established role in bone health, and inadequate levels matter. That does not make extra supplementation a universal ageing treatment: studies of disease prevention in people who already have adequate levels have not consistently supported the broad benefits suggested by observational associations. Correcting a deficiency and trying to extend lifespan are different research questions. Source ↗ Recently: No update dated within the past 30 days is recorded in our collection.
