What They Agree On
Both Tim Ferriss and Rhonda Patrick include these 3 products in their protocols — a signal of strong evidence and broad expert consensus.
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.
Magnesium (Threonate/Glycinate)
supplements
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
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
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.
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 Rhonda Patrick's Protocol
Sulforaphane / Broccoli Sprout Extract
Concentrated sulforaphane from broccoli sprout extract, a potent activator of the body's Nrf2 antioxidant pathway. Supports detoxification, reduces inflammation, and has been extensively studied for its cellular protective properties. Best absorbed when taken with a source of myrosinase.
Broccoli Sprouts
Fresh broccoli sprouts or sprouting seeds, the richest natural source of sulforaphane. Three-day-old sprouts contain 10-100 times more sulforaphane than mature broccoli. Easy to grow at home with a sprouting kit for a continuous supply of this powerful phytonutrient.
Vitamin C
High-quality vitamin C supplement supporting immune function, collagen synthesis, and antioxidant defense. Essential for tissue repair and iron absorption. Liposomal forms offer enhanced bioavailability compared to standard ascorbic acid.
Creatine Monohydrate
Pure creatine monohydrate, one of the most well-researched supplements in sports science. Supports muscle strength, power output, and emerging research suggests cognitive benefits. Safe for long-term daily use at 3-5 grams per day.
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.
Melatonin (Low Dose)
Low-dose melatonin supplement to support natural circadian rhythm and sleep onset. Research suggests doses of 0.3-1 mg are often more effective than higher amounts for improving sleep quality. Also studied for its antioxidant properties and potential anti-aging benefits.
Zinc (Picolinate)
Zinc picolinate supplement offering superior absorption compared to other zinc forms. Supports immune function, hormone production, and wound healing. Important for maintaining testosterone levels and thyroid health, particularly in those with dietary deficiencies.
Probiotics (Multi-Strain)
Multi-strain probiotic supplement containing diverse beneficial bacteria to support gut microbiome health. A balanced gut microbiome is linked to improved digestion, immune function, and mental well-being. Look for formulas with clinically studied strains and high CFU counts.
Glutathione (Liposomal)
Liposomal glutathione supplement for enhanced absorption of the body's master antioxidant. Glutathione plays a critical role in detoxification, immune support, and protecting cells from oxidative stress. Liposomal delivery bypasses digestive breakdown for greater bioavailability.
Vitamin K2 (MK-7)
Vitamin K2 in the MK-7 form supports proper calcium metabolism, directing calcium into bones and teeth while preventing arterial calcification. Works synergistically with vitamin D3 to optimize bone mineral density and cardiovascular health. Essential for activating proteins involved in blood coagulation and vascular protection.
Folate (Methylfolate 5-MTHF)
Bioactive methylfolate (5-MTHF), the body-ready form of folate critical for DNA synthesis, repair, and methylation. Unlike synthetic folic acid, methylfolate bypasses the MTHFR enzyme conversion step, making it effective for individuals with common MTHFR gene variants. Supports homocysteine metabolism, neural tube development, and red blood cell formation.
Calcium (1000mg)
Calcium is essential for bone health, muscle function, and cardiovascular health throughout life. Adequate calcium intake helps prevent osteoporosis and supports proper nerve transmission and blood clotting. Longevity experts recommend calcium supplementation, especially for older adults, to maintain bone density and reduce fracture risk with aging.
