New research upends argument for popular longevity supplement NAD+ touted by celebs
New research challenges the widely held belief that NAD+ levels decline with age, a claim often promoted by celebrities and influencers. A study published in Nature Metabolism found no evidence of a decline in blood NAD+ levels with aging, despite previous assumptions. While some experts remain skeptical, the findings suggest a need for reevaluation of the supplement's purported benefits for healthy aging.
- ▪A recent study shows that blood levels of NAD+ do not decline with age, contradicting popular claims.
- ▪The research analyzed blood samples from over 300 individuals, including both younger and older adults.
- ▪Experts acknowledge that while NAD+ levels may not drop in blood, declines could still occur in specific tissues.
