Godfather Of Biohacking Ranks Every Longevity Hack

Key wellness / biohacking strategies mentioned (Dave Asprey’s ranked review)

“S tier” (best-supported / highest value)

• Blackout curtains (sleep)

  • Strong observational dataset: increased light exposure is associated with higher type 2 diabetes risk.
  • Presented as “life-changing” and among the cheapest high-impact items.

• Blood flow restriction (BFR) training (movement)

  • Muscle growth can be comparable to heavy lifting using a band + light weights (about 20–40% of load).
  • Especially useful when joints limit heavier training (e.g., knees/shoulders) or for older adults.

• Creatine (nutrition → brain/energy)

  • Supported by many trials.
  • Positioned as brain energy support, including cognitive effects during low-energy states (e.g., sleep deprivation, stress, vegetarian diets).
  • Framed as one of the only supplements to earn S tier.

Best-supported “A tier” style interventions (high confidence but not top-ranked)

• Creatine (also S tier)

• Magnesium glycinate (sleep)

  • Helps people fall asleep faster (about 17 minutes faster cited).
  • Distinguishes it from poorly absorbed magnesium forms (e.g., oxide).

• Omega-3 (EPA/DHA) (aging biology)

  • One positive trial is cited using an “epigenetic aging clock.”
  • Warning: many products underdose EPA/DHA—check the actual EPA + DHA content, not only label “mg.”

• Vitamin D3 + K2 (cost/evidence/safety for deficiency)

  • Deficiency can be confirmed via blood tests.
  • K2 supports directing calcium to bones rather than arteries.

• Cold water immersion (recovery & soreness, with adaptation caution)

  • Can reduce muscle soreness.
  • Caution: if done right after heavy training, it may blunt gains—use on rest days or separate by hours.
  • Chamber vs cold bath: cold bath can perform as well or better in the cited comparison.

• Cooling mattress (sleep temperature management)

  • Claims increased deep sleep by keeping core temperature lower.
  • Practical alternatives mentioned: lighter bedding, or a warm shower ~90 minutes before bed.

• Hyperaric oxygen vs other “potential” therapies

  • Described as B tier (see below).

---

“B tier” (real effects but narrower / limited evidence or important caveats)

• Modafinil (wakefulness / planning & complex decisions)

  • Evidence: helps with planning/complex tasks; less for memory/attention.
  • Safety/interaction caution: can induce liver enzymes affecting hormonal birth control effectiveness.

• Apigenin (chamomile compound) (sleep)

  • Improves sleep quality in trials.
  • Not “sleep-lab-grade” data; dosing may be inconsistent across products.

• Nicotine (pouches/patch/lozenge; not smoking)

  • Small, short-lived improvements in attention/working memory.
  • Addiction risk + raises blood pressure (an anti-aging cost).
  • Emphasizes need for more formal studies.

• Urolithin A (pomegranate → autophagy signaling)

  • Some muscle strength improvement; endpoints not fully met.
  • Not everyone can make it from food (gut microbiome dependence).

• Ashwagandha (stress/sleep)

  • Cortisol reduction only with standardized extract at real doses.
  • Effects seen in randomized trials (stress + sleep quality).

• PEMF / vagus nerve wearables / neurofeedback (mixed evidence)

  • PEMF: mostly knee-pain signal; no strong longevity/energy/cellular claims.
  • Neurofeedback: consumer/online headbands criticized for sham-controlled issues; author notes higher value for clinician-led intensive work, but highlights difficulty proving with sham trials.
  • Vagus nerve wearables: mechanism plausible; strong outcomes limited in healthy people.

• Blood glucose monitoring feedback (CGMs)

  • No proof it directly improves lifespan, but described as a “feedback loop” that helps behavior change.
  • Key tip: trend matters more than the exact number.

• Red bulbs after sunset (circadian support)

  • Presented as helpful for sleep (separate from red light panels).

• Hyperbaric oxygen (B tier, “potential”)

  • Early study limitations (small sample, no control group).
  • Plausible mechanisms + some evidence in TBI/wound healing.

• Plasma exchange (B tier, promising but limited)

  • Improvements noted in a surrogate/endpoint design; single-blind; authors sell the treatment.
  • Strong emphasis on waiting for better-outcome trials.

---

“C tier” (some value for specific goals; mostly evidence missing or too inconsistent)

• Eltheanine (L-theanine)

  • Good subjective morning effect.
  • Limited aging data and small human studies.

• Berberine (glucose drug; not proven longevity)

  • Lowers blood glucose and can perform comparably to metformin in head-to-head trials.
  • Limits: poor absorption + no lifespan/aging outcome data.

• C60

  • Longevity claim traced to one small unreplicated rat study; no human trials.

• Methylene blue

  • Interesting mechanism; author takes it weekly.
  • Lacks human cognition/longevity trials.

• Spermidine capsule

  • Capsule trial showed no memory/biomarker effect.
  • Long-term benefits were associated with foods.

• Collagen

  • Skin improvements small/short-term.
  • If protein intake is low, prioritize whole protein (cheaper).

• Uplift but limited

  • Omega-3 dose precision caveat is already in A tier; broader supplement claims are weaker here.

• MCT with C8 (ketone-focused)

  • Can raise ketone metabolism.
  • Peak/GI side effects for a subset; start low.

• Activated charcoal

  • Works as described.
  • Indiscriminate binding makes it unsuitable as a routine longevity habit.

• Whole-body vibration

  • Mixed results.
  • No bone density benefit at 12 months.
  • Better for balance/mobility in frail older adults.

• Cold cryotherapy (C tier)

  • Feels great; does not beat placebo in performance.

• Ozone therapy (C tier)

  • No longevity trial.
  • Author references long clinical use in Europe + their own experience; “mechanism holds up.”

“D/F tier” (often marketed heavily; weak, unreplicated, or unsafe/uncertain)

F-tier examples (author is strongly negative)

• C60 (F): weak/no human evidence
• NMN/NR (D): mechanism plausible, but human results unreplicated so far
• Deuterium-depleted water (F): only company-provided human data
• Exosomes (F): FDA safety notification + clinic harm cases; no approved products
• NAD+ IV (F): no health span trial; much is excreted
• Young plasma (F): no clinical benefit trial
• EMF / “quantum” jewelry / router stickers (F): no measurable mechanism
• Structured water (F): nonsense
• Rapamy (D): best mouse data, but human trial missed the primary endpoint
• Stem cells for longevity claims (D): plausible for orthopedic injuries; no trials showing longevity benefit in healthy people

Not “because it doesn’t work,” but because evidence is missing or not convincingly replicated

• The author repeatedly emphasizes:
  • Trial quality and replication matter more than marketing.

Cross-cutting productivity / self-care principles emphasized (applies across the ranking)

• Use the “minimum effective dose” mindset

  • Find what works for you with the least effort instead of chasing everything.

• Measure what you can

  • Sleep trackers: don’t obsess over absolute deep-sleep numbers—track trends by changing one thing for ~2 weeks.
  • CGMs: same principle—trend > single number—and use it to guide food choices.

• Prioritize fundamentals before optimization

  • The author’s “four foundations”:
    • Sleep
    • Movement
    • Food (nutrition)
    • Relationships

• Adherence beats fancy

  • For interval training, the machine’s value is making it easy to consistently do high-intensity work.

• Safety / interactions matter

  • Examples included: modafinil interacting with hormonal birth control; nicotine raising blood pressure; sourcing concerns for peptides/exosome clinics.
