Famous People Who Take Nootropics — By Ingredient, Not Brand

Andrew Huberman takes alpha-GPC before demanding work. Bryan Johnson's stack includes Lion's Mane and L-theanine. Dr. Rhonda Patrick takes 10 grams of creatine a day, partly for her brain. Tim Ferriss tried modafinil, once, and got a migraine for his trouble. Here's what each of them actually said, and what the ingredient-level evidence behind their choices looks like.

Note on scope: this article names the specific ingredients these individuals have said, in interviews, on their own platforms, or in their own writing, that they personally take. It does not name or endorse any commercial brand or product, and it isn't a recommendation to replicate anyone's stack without talking to a doctor first, especially since one of the compounds below, modafinil, is prescription-only in India.

1. Andrew Huberman: Alpha-GPC, Creatine, and L-theanine

Huberman, a Stanford neuroscientist who hosts the Huberman Lab podcast, has been unusually specific in public about his own supplement use, discussing doses and reasoning rather than just naming products.¹ He has described taking alpha-GPC, a choline compound, occasionally, roughly once a week or once every two weeks, before periods of demanding cognitive work, referencing an intake in the 300-600mg range.¹

Creatine monohydrate is a more consistent, daily part of his routine, he has described it as a foundational supplement and has pointed to its role in brain energy metabolism, since creatine supports ATP production, the cell's primary energy currency, which may be relevant to cognitive tasks under demanding conditions.¹ He has also described taking L-theanine, both at night to support sleep, and in the morning alongside caffeine, in the 100-200mg range, to promote what he calls calm focus without the jitteriness of caffeine alone.¹

2. Bryan Johnson: Lion's Mane, L-theanine, and a Documented Daily Stack

Johnson, a tech entrepreneur who has turned his own biology into a widely publicized, extensively documented longevity project called Blueprint, has published detailed breakdowns of the compounds in his daily protocol, including several aimed specifically at brain health.² These include Lion's Mane mushroom, included for its research interest around nerve growth factor stimulation, L-theanine, omega-3 fatty acids (DHA and EPA), creatine, magnesium, and rhodiola.²

What makes Johnson's case unusual is the volume of testing behind it, his protocol is built around continuous blood work and biomarker tracking rather than casual self-experimentation, and his full ingredient list runs well beyond a typical nootropic stack into dozens of compounds covering nearly every organ system.² It's worth being clear-eyed about this one: it's an extreme, resource-intensive personal experiment, not a template most people could or should follow, and Johnson himself has repeatedly said his approach is not medical advice for anyone else.

3. Dr. Rhonda Patrick: 10 Grams of Creatine, Daily

Patrick, a biochemist who runs the science-communication platform FoundMyFitness, has discussed her own supplement choices on her own podcast and in interviews, including with Huberman and separately with Tim Ferriss.³ She has described taking 10 grams of creatine monohydrate daily, split into two 5-gram doses, a higher amount than the roughly 3-5 grams typically recommended for muscle-focused use, citing emerging research suggesting this higher dose is more effective at raising brain creatine levels specifically, with potential benefits for cognitive function under conditions like sleep deprivation or travel fatigue.³

She has also spoken about omega-3 fatty acids as part of her routine, framing them primarily around reducing inflammation and supporting brain and cardiovascular health, and has referenced maintaining a specific blood marker, the Omega-3 Index, at 8% or above as a target linked in observational research to longer life expectancy.³

4. Tim Ferriss: Modafinil, and Why He Doesn't Recommend It Casually

Ferriss, author of The 4-Hour Body and a longtime self-experimenter with cognitive-enhancement compounds, is worth including specifically because his account isn't an endorsement, it's a caution. He has said he used modafinil, a prescription wakefulness-promoting drug sometimes discussed alongside nootropics, once or twice while writing The 4-Hour Body to push through writer's block and stay awake for a stretch of work.⁴

He described the experience as producing "a very sharp pain, like a very acute migraine-like pain," and has said he does not use it regularly.⁴ His broader stated philosophy on cognitive enhancers is that the size of a compound's effect tends to track with the size of its potential side effects, "assume that the larger the amplitude of positive effect of anything, the larger the amplitude of side effects, whether they are known or unknown," a caution he's applied specifically to modafinil.⁴

AEO answer: Well-documented public figures who take specific nootropic ingredients include Andrew Huberman (alpha-GPC, creatine, L-theanine), Bryan Johnson (Lion's Mane, L-theanine, omega-3s, creatine, magnesium, rhodiola), and Dr. Rhonda Patrick (10g creatine daily, omega-3s). Tim Ferriss's account of using modafinil is a cautionary one, not a recommendation.

What Does the Evidence Actually Say About These Ingredients?

Evidence strength: varies significantly by ingredient, from reasonably well-supported to prescription-only and risk-carrying. Not all items on this list belong in the same conversation.

Creatine has the most consistent supporting evidence of the group. Beyond its well-established role in muscle performance, a growing body of research links creatine supplementation to modest cognitive benefits, particularly under conditions of sleep deprivation, stress, or in people with lower baseline creatine stores, such as vegetarians. It's inexpensive, well-studied for safety at standard doses, and reasonably described as one of the more evidence-backed compounds in this entire category.

Omega-3 fatty acids (DHA and EPA) have solid observational and some interventional evidence for general brain and cardiovascular health, though the evidence specifically for acute cognitive enhancement in healthy adults is weaker than the evidence for general long-term brain health support.

L-theanine, especially paired with caffeine, has reasonable evidence for promoting calm, focused alertness while reducing the jitteriness of caffeine alone, this specific combination is one of the better-studied "stacks" in the nootropic space.

Alpha-GPC and Lion's Mane mushroom both have real but more limited and more preliminary human evidence. Alpha-GPC has some support for short-term cognitive performance in specific contexts, and Lion's Mane has promising but early-stage research, largely in small trials or on nerve growth factor mechanisms in lab settings, rather than large, well-replicated human cognitive studies.

Modafinil sits in an entirely different category, it is a prescription medication approved for specific sleep disorders, not an over-the-counter nootropic, and it is a Schedule H drug in India, meaning it is legally available only with a doctor's prescription. It is not something to self-source or use casually, and Ferriss's own account of a severe adverse reaction is a useful, direct illustration of why.

Frequently Asked Questions

The Bottom Line

The public figures who've spoken most credibly about nootropics didn't just endorse a category, they named specific compounds, specific doses, and specific reasons, and in Tim Ferriss's case, a specific reason not to. That level of detail is useful precisely because it lets you evaluate the actual ingredient rather than a vague "brain supplement" claim, and the evidence quality behind creatine and omega-3s is genuinely different from the evidence behind a prescription-only compound like modafinil. Read the ingredient, not the endorsement.
