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 Steven Gundry's Protocol
Extra Virgin Olive Oil
Cold-pressed extra virgin olive oil, a cornerstone of Mediterranean and longevity diets. Rich in polyphenols and oleic acid.
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.
