Key Points:
- Nicotinamide adenine dinucleotide (N.A.D.+) has become a popular anti-aging supplement, endorsed by celebrities and influencers across genders.
- N.A.D.+ is essential for cellular metabolism, and it was widely believed that its levels decline with age, prompting the use of supplements to promote healthy aging.
- New research published in Nature Metabolism and a recent preprint study challenge this belief, showing that blood levels of N.A.D.+ do not actually decrease with age.
- The latest study analyzed over 300 individuals from diverse groups and confirmed that while supplementation can raise N.A.D.+ levels, there is no evidence that these levels drop as people get older.
- Experts suggest these findings should prompt a reevaluation of the assumptions behind N.A.D.+ supplementation and its purported anti-aging benefits.
