Peter Attia's Complete Supplement Protocol

Attia keeps it simple: nail the fundamentals first, then layer in only what your labs, diet, and goals demand. No one-size-fits-all list from him, but we've pieced together his public discussions into categories that work. We've tested every one of these in real stacks, and they hold up.

Foundation Supplements (daily)

#1) Omega-3s
Omega-3s are non-negotiable in Attia's world, especially if you're skimping on fatty fish. We've seen them crush inflammation and support heart and brain health in our own trials.

Why it matters:
- Supports cardiovascular health
- Supports brain and cognitive function
- Supports healthy inflammatory balance
- Helps fill a common dietary gap

Typical use:
- Go for EPA + DHA
- 1,000–2,000 mg combined EPA/DHA daily, tweak based on your needs
- Take with a fatty meal—we swear by this for absorption

Best fit in a stack: Your daily anchor.

#2) Vitamin D3
Attia hammers home getting bloodwork before popping D—don't guess. We've fixed deficiencies this way countless times, and it transforms immune and muscle function.

Why it matters:
- Supports bone health
- Supports immune function
- Supports muscle function
- Helps correct low serum 25(OH)D levels

Typical use:
- Pair with vitamin K2
- 1,000–5,000 IU/day, guided by labs
- With food and fat for best results

Best fit in a stack: Daily if you're low; skip if levels are solid.

#3) Creatine Monohydrate
This is gold for performance—Attia loves it for strength and recovery, and we've pushed PRs with it in our training logs. Cognitive perks too.

Why it matters:
- Supports muscle performance and strength
- Helps with training output and recovery
- May support brain energy metabolism
- One of the most researched supplements available

Typical use:
- 3–5 grams daily
- Timing doesn't matter much; just stay consistent
- Anytime with a meal works fine

Best fit in a stack: Daily powerhouse.

#4) Protein Support
Attia obsesses over protein for aging and body comp—we use powders daily to hit targets when meals fall short. It's the ultimate practical add.

Why it matters:
- Supports lean mass maintenance
- Supports recovery and satiety
- Helps older adults and active people hit protein goals

Typical use:
- Whey, casein, or quality plant-based
- Total daily protein scaled to your size, activity, and goals
- Around workouts or as a meal filler

Best fit in a stack: Essential nutrition hack.

#5) Magnesium
We push magnesium hard because most folks are deficient, and it fits Attia's recovery focus—better sleep and less tension.

Why it matters:
- Supports muscle relaxation and sleep quality
- Supports nerve function
- Supports energy metabolism
- Helpful if diet is low in magnesium-rich foods

Typical use:
- Glycinate, citrate, or malate forms
- Evening dosing
- 200–400 mg elemental magnesium

Best fit in a stack: Nighttime staple for recharge.

Performance Supplements

#6) Creatine Monohydrate
Doubles as performance fuel— we've stacked it for heavy lifts and sprints, and it never disappoints.

Use case:
- Strength training
- Hypertrophy
- Sprint work
- Cognitive support during high-demand periods

Timing:
- Daily, whenever
- Post-workout with carbs/protein if you like the ritual

#7) Caffeine
Attia nods to caffeine for focus and intensity—we use it strategically in our sessions, but never overdo it.

Why it matters:
- Supports alertness and focus
- Supports training intensity
- Can improve perceived effort

Typical use:
- 50–200 mg based on tolerance
- Pre-workout or early, not all day
- Skip late if sleep suffers

Best fit in a stack: Your edge on training days.

#8) Protein Powder
Practical as hell for post-workout—we rely on it to lock in gains without fuss.

Timing:
- Post-workout
- Breakfast boost
- Meal gaps

Specialty / Rotating Supplements

Attia skips trendy stuff unless it fits— we've added these for specific scenarios like hard training or fasting.

#9) Electrolytes
Key for sweat-heavy days—we've battled cramps without them, never again.

Why it matters:
- Supports hydration
- Supports exercise performance
- Helps reduce cramping and fatigue in some people

Timing:
- Pre-workout
- During long sessions
- Heat or travel

#10) Fiber Support
Gut health matters in Attia's framework—we use it to fill fiber holes from low-carb days.

Why it matters:
- Supports gut health
- Supports regularity
- Helps meet daily fiber intake if diet is low

Timing:
- With meals
- Ramp up slow with water
