What They Agree On
Both Hiroki Shinkai and Peter Attia include these 4 products in their protocols — a signal of strong evidence and broad expert consensus.
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.
Creatine Monohydrate
supplements
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
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
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.

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

Only in Hiroki Shinkai'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.
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.
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.
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.

Only in Peter Attia's Protocol
Electrolyte Mix
Balanced electrolyte mix containing sodium, potassium, and magnesium to support hydration and cellular function. Essential for maintaining energy levels, muscle function, and cognitive performance, especially during fasting or exercise. Sugar-free formulas are preferred in longevity protocols.
