Supplements for Longevity & Their Efficacy | Dr. Peter Attia
Huberman Lab Podcast Recap

Duration: 2 hr 30 min
Guests: Dr. Peter Attia
Summary
Andrew Huberman and Dr. Peter Attia examine the effectiveness of various supplements for enhancing longevity and healthspan. They scrutinize molecules such as NAD, NMN, and NR, while emphasizing the greater impact of lifestyle factors like exercise and nutrition.
What Happened
Andrew Huberman, a Stanford professor, and Dr. Peter Attia, a renowned physician, dissect the efficacy of supplements such as NR, NMN, and NAD in extending lifespan. They explore how these molecules are involved in the NAD pathway, which is crucial for cellular energy production and mitochondrial function. However, they express skepticism about their benefits for longevity, noting a lack of substantial evidence.
Rapamycin and caloric restriction stand out as the only interventions proven to extend life across multiple species. Dr. Attia shares his own experience with rapamycin, which he takes weekly but notes that it can cause side effects like mouth sores. The ongoing DOG study on rapamycin's effects on dogs could offer new insights by 2026.
Sirtuins, which consume NAD for DNA repair, are discussed for their role in longevity. While overexpression of sirtuins has shown to extend lifespan in yeast, Dr. Attia mentions that this is not necessarily linked to caloric restriction. The decline of NAD with age is highlighted, especially in skin cells, which may explain observations about skin cancer reduction with NR and NMN.
Dr. Attia and Huberman are cautious about recommending NMN and NR supplements, given the FDA's ruling against NMN as a supplement and the limited evidence supporting their efficacy. They also discuss the commercial debate between NMN and NR, noting there is no scientific reason to favor one over the other.
The importance of lifestyle factors such as exercise, sleep, and nutrition is emphasized as more impactful than supplements. Dr. Attia and Huberman both follow supplement regimens but stress that behavioral factors are more critical for health and longevity.
Mitochondrial function and its decline with age are addressed, with Glenn Jeffrey's research suggesting that red and near-infrared light can improve mitochondrial function in aged eyes. Exercise and proper sleep are again underscored as vital components of a longevity strategy.
The episode concludes with a discussion on biological aging tests, which Dr. Attia argues may not reliably predict lifespan or healthspan. Chronological age remains a better indicator, and maintaining a physiologic reserve through middle age is crucial for vitality in later years.
Key Insights
- Dr. Peter Attia and Andrew Huberman emphasize the lack of evidence supporting the use of NAD, NMN, and NR supplements for extending lifespan. While these molecules play a role in cellular energy production, their benefits for longevity remain unproven.
- Rapamycin and caloric restriction are highlighted as the only interventions with consistent evidence of life extension across multiple species. Dr. Attia takes rapamycin weekly but notes potential side effects like mouth sores.
- NAD levels decline significantly with age, particularly in the skin, which may explain observations of reduced skin cancer with NR and NMN supplementation. However, there is no clear evidence to support the widespread use of these supplements for longevity.
- Lifestyle factors such as exercise, sleep, and nutrition are emphasized as far more impactful on health and longevity than any supplement. Both Dr. Attia and Huberman focus on these behavioral factors as the cornerstone of their longevity strategies.
