Aging is an information problem — the body loses the epigenetic instructions that tell cells how to function. Sinclair's protocol targets NAD⁺ restoration, sirtuin activation, and mTOR suppression to slow the loss of that information and, in animal models, partially reverse it.

Supplement Stack

NMN
1 g
II
Timing:Morning, with first meal
Nutrient-sensing dysreg.Stem cell exhaustion
Sinclair uses NMN; NR is a structural alternative with similar mechanism
Resveratrol
1 g
II
Timing:Morning, with yoghurt or olive oil (fat required for absorption)
Nutrient-sensing dysreg.Epigenetic alterations
Sinclair takes with fat to improve bioavailability
TMG (betaine)
1 g
II
Timing:Morning
Telomere attritionEpigenetic alterations
Methyl donor to offset NMN-driven SAM depletion
Metformin
500–1000 mg
I
Timing:Evening with dinner
Nutrient-sensing dysreg.Cellular senescence
Prescription only. Sinclair pauses on heavy exercise days (may blunt adaptation)
Rx only — not added to cart
Statin (rosuvastatin)
10 mg
I
Timing:Evening
Microbiome alterations
Prescription only. Cardiovascular risk management.
Rx only — not added to cart
Vitamin D3
4000–5000 IU
I
Timing:Morning with fat
Disabled autophagyMicrobiome alterations
Vitamin K2 (MK-7)
180 µg
II
Timing:Morning with fat
Microbiome alterations
Paired with D3 for calcium routing
Quercetin
500 mg
II
Timing:Morning
Altered intercellular comm.
Senolytic — Sinclair cycles this
Spermidine
1 mg
II
Timing:Morning
Disabled autophagy
Alpha lipoic acid (ALA)
600 mg
II
Timing:Morning
Mitochondrial dysfunction

Tier I = multiple RCTs in humans · Tier II = human trials, early stage · Tier III = mechanism / animal studies only

Lifestyle Pillars

  • 1Intermittent fasting (skips breakfast, eats in a 6–8 hour window)
  • 2Vigorous exercise 3–5× per week including HIIT and resistance training
  • 3Cold exposure — cold showers or ice baths 2–3× per week
  • 4Avoids excess protein (mTOR suppression) — plant-forward diet
  • 5Tracks biological age using epigenetic clock tests (Horvath, GrimAge)
  • 6Minimises sugar and refined carbohydrates
  • 7Prioritises 7–8 hours of sleep

Important Caveats

Metformin and statins are prescription medications. Sinclair's protocol is a self-experiment, not a clinical recommendation. The TAME trial (Targeting Aging with Metformin) is ongoing and will provide higher-quality evidence. Resveratrol bioavailability in humans remains debated; the SIRT1 activation mechanism is contested.
