What They Agree On
Both Tim Ferriss and David Sinclair include these 3 products in their protocols — a signal of strong evidence and broad expert consensus.
Vitamin D3 (5000 IU)
High-potency vitamin D3 supplement providing 5000 IU per serving to support optimal blood levels. Essential for immune function, bone health, and mood regulation. One of the most widely recommended supplements among longevity researchers due to widespread deficiency.
Vitamin D3 (5000 IU)
supplements
Omega-3 Fish Oil (High EPA)
High-potency omega-3 fish oil supplement with elevated EPA content. Supports cardiovascular health, reduces systemic inflammation, and promotes healthy brain function and mood regulation.
Omega-3 Fish Oil (High EPA)
supplements
Green Tea (Matcha)
High-quality matcha green tea powder rich in EGCG catechins and L-theanine. Provides calm, sustained energy while delivering powerful antioxidant and anti-inflammatory benefits. Regular green tea consumption is associated with reduced cardiovascular disease risk and improved metabolic health in population studies.

Where They Differ
These products are unique to one protocol — reflecting each expert's distinct philosophy, research focus, and priorities.

Only in Tim Ferriss's Protocol
Magnesium (Threonate/Glycinate)
Highly bioavailable magnesium in threonate or glycinate form for superior absorption. Supports deep sleep quality, cognitive function, and nervous system relaxation. Magnesium threonate is particularly valued for its ability to cross the blood-brain barrier.
Fermented Foods (Kimchi, Sauerkraut, Kefir)
Naturally fermented foods rich in live beneficial bacteria to support gut microbiome diversity. Regular consumption of kimchi, sauerkraut, and kefir has been shown to reduce markers of systemic inflammation. A Stanford study found fermented foods increased microbial diversity more effectively than a high-fiber diet.

Only in David Sinclair's Protocol
NAD+ Precursor (NMN/NR)
NAD+ precursor supplement in NMN (nicotinamide mononucleotide) or NR (nicotinamide riboside) form. Supports cellular energy production and DNA repair by boosting NAD+ levels, which naturally decline with age. A cornerstone supplement in many longevity-focused protocols.
Extra Virgin Olive Oil
Cold-pressed extra virgin olive oil, a cornerstone of Mediterranean and longevity diets. Rich in polyphenols and oleic acid.
