长寿补充剂：白藜芦醇、NR、NMN及其他

摘要

Andrew Huberman 回顾了目前讨论最广泛的长寿补充剂——白藜芦醇、NR、NMN、NAD静脉输注、二甲双胍、小檗碱和雷帕霉素——分享了当前的科学证据及他个人的使用方案。他的结论是，尽管其中某些化合物可能有助于改善精力和活力，但均无充分证据支持将其作为专门延长寿命的补充剂使用。基础生活方式行为的影响远超任何补充剂或药物。

核心要点

  • 白藜芦醇作为延寿补充剂的说法已基本被推翻；现有证据不支持其能延长人类寿命。
  • 葡萄籽提取物（每日随餐服用 400–800 mg）可能有助于血管功能和血液循环，但并非首选补充剂推荐。
  • NR 和 NMN 可提升 NAD 水平，或可改善主观精力和活力，但目前尚无有力证据证明其能延长寿命。
  • NAD 静脉输注（500–1,000 mg IV）在输注过程中会产生明显但令人不适的副作用，最好在白天较早时进行，以避免影响睡眠。
  • 二甲双胍、小檗碱和雷帕霉素目前不在 Huberman 的用药方案中，原因是延寿证据不足和/或个人副作用。
  • 没有任何补充剂或药物能接近高质量睡眠和规律运动所带来的长寿益处。
  • 基础必须优先：在考虑补充剂之前，应先优化睡眠、日照、营养、运动、压力调节和社交连接。

详细笔记

白藜芦醇

  • 因具有激活与延寿相关细胞通路的潜力而受到广泛关注。
  • Grape seed extract 含有白藜芦醇或可转化为白藜芦醇；曾因类似原因而流行。
  • 截至 2023 年，白藜芦醇能延长寿命的证据已基本被推翻。
  • Huberman 个人用法：每日随餐服用 400–800 mg 葡萄籽提取物，用于血管和血流方面的益处——而非延寿。
  • 不会将葡萄籽提取物列入其前 10 名补充剂推荐。

NR 和 NMN（NAD 前体）

  • NAD（烟酰胺腺嘌呤二核苷酸）是 cellular energetics 和 mitochondrial function 的核心物质，随年龄增长自然下降。
  • NR 和 NMN 是可提高细胞内 NAD 水平的前体物质。
  • 关于 NMN 是否能被有效吸收并在细胞内转化为 NAD，目前仍存在争议。
  • Huberman 个人方案：
    • 每日 500 mg NR
    • 每日 1–2 克舌下含服 NMN（置于舌下）
    • 在早晨服用，通常在第一餐（约上午 11 点）前 30 分钟至 2 小时
  • 报告的主观效果： 全天持续的脑力和体力，且不影响睡眠。
  • 他服用 NR/NMN 并非为了延长寿命——仅为主观活力方面的益处。
  • 监管说明： 截至 2023 年，NMN 已在一项临床试验中作为试验性药物进行申报，这在技术层面使其无法作为商业补充剂销售（尽管在公开市场上仍可找到）。

NAD 静脉输注

  • 直接静脉输注 NAD；被认为比口服补充剂更能有效提升细胞内 NAD 水平。
  • Huberman 已进行过两次，剂量为 500–1,000 mg IV。
  • 用于病后恢复或感觉身体虚弱时。
  • 输注过程中的副作用： 恶心、胸部压迫感、腿部不适——通常在约 10 分钟内缓解。
  • 放慢滴注速度可减轻不适感。
  • 输注后效果：睡眠改善、精力提振、恢复加快。
  • 最好在白天较早时进行，以避免影响睡眠。
  • 口服 NAD 产品存在，但缺乏直接证据证明其能提升细胞内 NAD 水平。
  • 被认为费用高昂、不便且令人不适；Huberman 估计每年仅在必要时使用数次。

二甲双胍和小檗碱

  • 两者均与降低血糖和减少 mTOR（哺乳动物雷帕霉素靶蛋白）活性相关。
  • mTOR 在细胞生长和发育期间高度活跃；抑制其活性在理论上有助于长寿。
  • 小檗碱： Huberman 不服用——会引起严重头痛，可能与降低血糖有关。
  • 二甲双胍： Huberman 不服用；引用与 Dr. Peter Attia 的评述，结论是目前缺乏足够的同行评审数据支持二甲双胍用于延长寿命。

雷帕霉素

  • 以其作为哺乳动物雷帕霉素靶蛋白而得名；主要用作抗癌药物。
  • Dr. Matt Kaeberlein（华盛顿大学）正积极研究其长寿用途，包括一项犬类长寿项目。
  • Huberman 目前不服用雷帕霉素。
  • 原因：目前尚无足够证据证明其副作用风险在寿命延长方面是合理的。
  • 指出 Peter Attia 等临床医生对其潜力更为乐观。

基础长寿行为（非补充剂）

Huberman 强调这些行为的影响远超任何补充剂：

  • 睡眠： 每晚充足、高质量的睡眠；睡眠剥夺会直接和间接缩短寿命。
  • 运动：
    • 2 区有氧训练： 每周至少 180–220 分钟（能正常交谈的配速）
    • 最大摄氧量训练： 每周至少一次高强度有氧训练
    • 抗阻训练： 每块肌肉每周至少 6 组，以保持肌肉量、力量和神经-肌肉连接（与认知功能相关）
  • 晨间日照： 设定 circadian rhythm，为所有其他健康行为奠定基础
  • 营养： 优质的饮食摄入
  • 压力调节
  • 社交连接： 减少有害关系，增加有益关系

Longevity Supplements: Resveratrol, NR, NMN, and Beyond

Summary

Andrew Huberman reviews the most commonly discussed longevity supplements—resveratrol, NR, NMN, NAD infusions, metformin, berberine, and rapamycin—sharing both the current scientific evidence and his personal protocols. He concludes that while some of these compounds may support energy and vitality, none have sufficient evidence to justify taking them specifically for lifespan extension. Foundational lifestyle behaviors remain far more impactful than any supplement or drug.

Key Takeaways

  • Resveratrol has been largely debunked as a lifespan-extending supplement; current evidence does not support it extending human longevity.
  • Grape seed extract (400–800 mg/day with a meal) may support vascular function and blood flow, but is not a top-tier supplement recommendation.
  • NR and NMN can increase NAD levels and may improve subjective energy and vitality, but do not yet have strong evidence for extending lifespan.
  • NAD infusions (500–1,000 mg IV) produce notable but uncomfortable side effects during administration, and are best done earlier in the day to avoid sleep disruption.
  • Metformin, berberine, and rapamycin are not currently part of Huberman’s regimen due to insufficient lifespan evidence and/or personal side effects.
  • No supplement or drug comes close to the longevity benefits of quality sleep and consistent exercise.
  • The basics must come first: sleep, sunlight, nutrition, movement, stress modulation, and social connection should all be optimized before considering supplementation.

Detailed Notes

Resveratrol

  • Received significant attention for potential to activate cellular pathways linked to lifespan extension.
  • Grape seed extract contains or can be converted into resveratrol; was popular for similar reasons.
  • As of 2023, evidence that resveratrol extends lifespan has largely been debunked.
  • Huberman’s personal use: 400–800 mg grape seed extract daily with a meal, taken for vascular and blood flow benefits—not longevity.
  • Would not rank grape seed extract in his top 10 supplement recommendations.

NR and NMN (NAD Precursors)

  • NAD (nicotinamide adenine dinucleotide) is central to cellular energetics and mitochondrial function; naturally declines with age.
  • NR and NMN are precursors that can raise intracellular NAD levels.
  • Debate exists around whether NMN is effectively absorbed and converted to NAD in cells.
  • Huberman’s personal protocol:
    • 500 mg NR daily
    • 1–2 grams sublingual NMN daily (placed under the tongue)
    • Taken in the morning, typically 30 minutes to 2 hours before the first meal (~11 a.m.)
  • Subjective effects reported: Sustained mental and physical energy throughout the day, without disrupting sleep.
  • He does not take NR/NMN for lifespan extension—only for subjective vitality benefits.
  • Regulatory note: As of 2023, NMN was filed as an experimental drug in a clinical trial, making it technically unavailable as a commercial supplement (though still findable on the open market).

NAD Infusions

  • Direct intravenous infusion of NAD; assumed to be more effective at raising cellular NAD than oral supplements.
  • Huberman has done this twice, at doses of 500–1,000 mg IV.
  • Used post-illness or when feeling run-down.
  • Side effects during infusion: Nausea, chest pressure, leg discomfort—typically resolving within ~10 minutes.
  • Slowing the drip rate can reduce discomfort.
  • Post-infusion effects: improved sleep, increased vigor, faster recovery.
  • Best performed earlier in the day to avoid sleep disruption.
  • Oral NAD products exist but lack direct evidence linking them to increased cellular NAD levels.
  • Considered expensive, inconvenient, and uncomfortable; Huberman estimates using them only a few times per year if needed.

Metformin and Berberine

  • Both are associated with lowering blood glucose and reducing mTOR (mammalian Target of Rapamycin) activity.
  • mTOR is highly active during cellular growth and development; reducing it is theorized to support longevity.
  • Berberine: Huberman does not take it—causes him severe headaches, likely due to blood glucose lowering.
  • Metformin: Huberman does not take it; cites a review with Dr. Peter Attia concluding insufficient peer-reviewed data to support metformin for lifespan extension.

Rapamycin

  • Named for its role as the mammalian Target of Rapamycin; primarily used as an anticancer drug.
  • Under active research by Dr. Matt Kaeberlein (University of Washington) for longevity, including a dog longevity project.
  • Huberman does not currently take rapamycin.
  • Reason: insufficient evidence to justify its side effect profile for lifespan purposes at this time.
  • Notes that clinicians like Peter Attia are more enthusiastic about its potential.

Foundational Longevity Behaviors (Non-Supplement)

Huberman emphasizes these carry far greater impact than any supplement:

  • Sleep: Sufficient, quality sleep nightly; sleep deprivation directly and indirectly shortens lifespan.
  • Exercise:
    • Zone 2 cardio: Minimum 180–220 minutes/week (conversational pace)
    • VO2 max work: High-intensity cardio at least once/week
    • Resistance training: Minimum 6 sets per muscle group per week to preserve muscle, strength, and nerve-to-muscle connectivity (linked to cognitive function)
  • Morning sunlight: Sets circadian rhythm, anchoring all other health behaviors
  • Nutrition: Quality food intake
  • Stress modulation
  • Social connection: Reducing toxic relationships and increasing enriching ones
