Bryan Johnson takes over 100 daily supplements and spends roughly $2,000/month on his Blueprint protocol. Peter Attia takes about 10 and spends around $120/month. These are the two most visible approaches to longevity supplementation — maximum coverage versus targeted minimalism. I’ve tried both philosophies over the past seven years and ended up somewhere in the middle at 8 supplements and $100-200/month.

The gap between these two approaches isn’t just about money. It reflects a fundamental disagreement about how much evidence you need before adding something to your daily routine. That disagreement matters for anyone building their own stack.

Johnson’s Maximalist Philosophy

Bryan Johnson treats aging like an engineering problem. His Blueprint protocol isn’t just supplements — it’s a complete system of diet, exercise, sleep, and pharmacological intervention measured against hundreds of biomarkers monthly.

The supplement component alone is staggering. Over 100 pills daily, including NMN, resveratrol, metformin, rapamycin, lithium, DHEA, pregnenolone, and dozens of others. Many are prescription medications, not over-the-counter supplements. Johnson has a full medical team managing his protocol and gets blood panels that most people never see.

His argument boils down to this: if there’s even weak evidence something might help, and the risk profile is acceptable, take it. The cost of missing out on a real anti-aging intervention outweighs the cost of supplements that turn out to be useless. When you’re trying to not die, a few hundred dollars a month on speculative compounds is a rounding error.

Johnson publishes his results publicly, including his biological age measurements. He claims to have the heart of a 37-year-old and the fitness of an 18-year-old (he’s in his late 40s). The data is impressive, though separating the supplement effects from his extreme exercise, diet, and sleep optimization is impossible.

The honest criticism: nobody knows which of Johnson’s 100+ supplements are actually doing anything. He’s running a massively confounded experiment on himself. If he’s getting results, it’s probably 80% exercise and nutrition, not pill number 87.

Attia’s Minimalist Philosophy

Peter Attia’s approach to supplements is almost the opposite of Johnson’s. In his book Outlive and on The Drive podcast, Attia has consistently argued that most supplements have weak evidence and that people dramatically overweight pills relative to exercise, sleep, and nutrition.

Attia’s longevity protocol focuses on what he calls the “four pillars” — exercise, nutrition, sleep, and emotional health. Supplements are a distant fifth priority. When he does supplement, he sticks to things with strong clinical evidence: omega-3 fatty acids, vitamin D, and magnesium. About 10 items total, spending roughly $120/month.

His argument: most supplements are expensive placebos. The clinical trial evidence for the vast majority of compounds is either nonexistent, negative, or based on mouse studies that don’t translate to humans. You’re better off spending that $2,000/month on a personal trainer, a sleep coach, or higher-quality food.

Attia is particularly blunt about NMN and resveratrol — two of Johnson’s and Sinclair’s core supplements. He considers the human evidence insufficient to justify the cost. When I covered the NMN debate between Huberman and Attia, the evidence gap was the central issue.

The honest criticism of Attia’s approach: he may be too conservative. Some interventions that lack large clinical trials still have strong mechanistic evidence. Waiting for perfect data means you might miss years of potential benefit from compounds that eventually prove useful.

The Cost Comparison

The diminishing returns problem is obvious from the numbers. Going from 0 to 4 core supplements costs about $40-50/month and covers the highest-evidence items. Going from 4 to 10 adds another $70-80/month for moderate-evidence items. Going from 10 to 100+ costs $1,800+/month for increasingly speculative compounds. Each additional supplement has a lower probability of providing real benefit.

Where I Landed (8 Supplements, $100-200/Month)

I started closer to Johnson’s philosophy than I’d like to admit. In my first year of serious supplementation, I was taking 12-15 different things. Resveratrol because Sinclair takes it. Zinc because someone on Reddit said it helped. A greens powder because the marketing was convincing. My monthly spend was pushing $300.

Then I started cutting. Resveratrol went first — took it for months, noticed zero change in how I felt or in my bloodwork. Zinc followed. The greens powder was next. Each cut was hard because of loss aversion — what if this was the one actually doing something?

My current 8 daily supplements:

1. Omega-3 (Carlson fish oil) — strongest evidence, every expert agrees
2. Vitamin D3+K2 — bloodwork confirmed I was low before supplementing
3. Magnesium Glycinate — sleep improvement was noticeable within a week
4. Creatine monohydrate — gym performance and the emerging brain health data
5. NMN (500mg) — my speculative bet, strong mechanistic case
6. CoQ10 (Ubiquinol) — heart health, family history motivated this one
7. NAC — glutathione precursor, liver support
8. L-Theanine — takes the edge off caffeine, improves focus without drowsiness

The pattern is clear: my stack got smaller as I learned more. The trend was toward Attia, not Johnson. I cut what I couldn’t feel or measure. What remained is a core of four consensus supplements, two with personal evidence (sleep improvement from magnesium, gym performance from creatine), and two speculative bets (NMN and CoQ10).

I’ve documented the full reasoning and my complete 2026 stack with costs here.

The Supplements Where They Agree

Amid all the disagreement, Johnson and Attia overlap on a few things. Both protocols include omega-3 fatty acids, vitamin D, and magnesium. These are the supplements with the strongest clinical evidence — hundreds of randomized controlled trials, clear deficiency data, and measurable biomarker improvements.

When I compared what all six major longevity experts agree on, the same pattern held. Omega-3, vitamin D, and magnesium appear in nearly every expert protocol. Creatine is a near-consensus pick as well, with Brad Stanfield and Huberman both including it.

If you’re just starting, that’s your answer. Four supplements, about $40-50/month. Everything beyond that is increasingly a judgment call based on your health goals, family history, budget, and how comfortable you are with weaker evidence.

You can see exactly where all six experts overlap and diverge in the Research Hub tool, which maps every supplement to the experts who take it.

Which Philosophy Should You Follow?

Follow Attia’s minimalist approach if:

• You want to spend under $100/month on supplements
• You prefer strong clinical evidence before taking anything
• You’re willing to invest more in exercise, sleep, and nutrition instead
• You don’t have specific health conditions driving supplementation choices

Lean toward Johnson’s maximalist approach if:

• Budget isn’t a constraint (you can spend $500+/month without stress)
• You have access to a medical team for monitoring
• You get frequent bloodwork to track what’s actually changing
• You’re comfortable with speculative supplementation

Land in the middle (like I did) if:

• You want to cover the evidence-based basics plus a few calculated bets
• You’re willing to spend $100-200/month
• You get bloodwork at least twice a year and adjust based on results
• You treat your stack as a living experiment — willing to cut what isn’t working

The right approach isn’t static. I started maximalist and moved toward minimalism. Your stack should evolve as you collect data on what works for your body. Use the Cost Calculator to compare what each expert spends and decide where your budget goes furthest.
