Layne Norton vs Peter Attia
Compare Layne Norton's evidence-based protocol with Peter Attia's Outlive approach. Both are rigorous skeptics who demand clinical evidence before recommending any intervention — Norton comes from nutritional science and competitive bodybuilding with a focus on protein and resistance training for body composition, while Attia approaches longevity from a physician's perspective targeting the four horsemen of chronic disease through zone 2 cardio, strength, and metabolic screening. They share a minimalist supplement philosophy and mutual respect for data.

Layne Norton
PhD in Nutritional Sciences & Natural Bodybuilder
A rigorously evidence-based approach to nutrition and supplementation that prioritizes protein intake, resistance training, and a small number of well-validated supplements — rejecting health fads in favor of what the research actually supports.
10 products in protocol

Peter Attia
Physician & Longevity Researcher
A Medicine 3.0 framework focused on the four horsemen of chronic disease, emphasizing zone 2 cardio, strength training, metabolic health, and early biomarker screening.

What They Agree On
Both Layne Norton and Peter Attia include these 5 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
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
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
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.

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

Only in Layne Norton's Protocol
Whey Protein Isolate
Whey protein isolate is a fast-absorbing, complete protein derived from milk that delivers all essential amino acids with minimal fat and lactose. It is one of the most well-studied supplements for supporting muscle protein synthesis, recovery from exercise, and preservation of lean mass during caloric restriction.
Black Coffee
High-quality black coffee, one of the most widely recommended beverages during intermittent fasting. Contains caffeine and chlorogenic acid, which may increase metabolic rate and fat oxidation. Dr. Jason Fung considers black coffee an excellent fasting companion — it suppresses appetite, does not stimulate insulin, and may enhance the metabolic benefits of fasting.
Pasture-Raised Eggs
Pasture-raised eggs are a nutrient-dense whole food providing complete protein, healthy fats, choline, and fat-soluble vitamins. Among protein sources, eggs produce one of the lowest insulin responses — making them a preferred choice in Dr. Jason Fung's protocol for meals that support metabolic health and stable blood sugar.
Collagen Protein
Collagen protein supplements provide the specific amino acids — glycine, proline, and hydroxyproline — needed to support skin elasticity, joint cartilage, and connective tissue repair. While similar to collagen peptides, collagen protein powders are often formulated for use as a protein source in smoothies and baking.
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.
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.
