Food & Supplements for Brain Health: The Six Compounds That Support Cognition
Andrew Huberman lays out a short, evidence-anchored list of food-derived compounds that support the structure and function of brain cells: omega-3 fatty acids, phosphatidylserine, choline, creatine, anthocyanins and glutamine. He then explains the three channels that decide which foods we actually want — taste on the tongue, subconscious nutrient sensing in the gut, and belief — and how that third channel makes food preference learnable rather than fixed.
Overview
This Huberman Lab Essentials episode splits into two halves. The first is a ranked list of what to eat for the brain, starting not with fuel but with structure: neuronal membranes are built from structural fat, so essential fatty acids (EPA and DHA) come first, with fish, chia seeds, walnuts and soybeans as food sources and 1.5–3 g of EPA per day as the discussed range. Phosphatidylserine, abundant in meat and fish, follows. Choline comes third, because it feeds the biosynthesis of acetylcholine — the neuromodulator Huberman calls the brain's electrical highlighter pen for focus — with egg yolks as the richest source and 500–1,000 mg per day as the general target.
Creatine at roughly 5 g per day appears next, with evidence for cognition and for frontal circuits tied to mood and motivation. The list closes with anthocyanins from dark, thin-skinned berries and glutamine, an amino acid found in cottage cheese and protein-rich foods that may blunt sugar cravings via gut-to-brain satiety signals. The second half turns to preference: taste receptors on the tongue route through the gustatory nerve to the insular cortex, neuropod cells in the gut report amino acid, sugar and fat content subconsciously and trigger dopamine, and learned association ties a flavour to the metabolic payoff it predicts.
Huberman describes artificial sweetener studies showing that pairing a non-caloric sweet taste with a glucose-raising food can later shift insulin release, and Alia Crum's milkshake work showing that what people are told about a shake changes their measured hormonal response. The practical conclusion: pair a brain-supporting food you don't love with something that raises brain metabolism, and within about 7 to 14 days it starts tasting better to you.
Key quotes
5The most important food element for brain function is fat.
Acetylcholine is kind of an electrical highlighter pen, if you will, by analogy.
There is not any law that says that you have to get them from supplementation.
What you're seeking, even though you don't realize it, is things that allow your neurons to be metabolically active.
This is a belief effect. This is not placebo.
Key ideas
9Three signals decide what you eat
Food choice is driven by a subconscious gut signal about nutrient content, by how metabolically accessible a food is to the brain, and by belief — what you think the food contains and will do for you. The third is the one you can deliberately work with.
Structural fat builds the brain
Neurons and other brain cells are bounded by a double-layered membrane made of fat, and what crosses that boundary regulates electrical activity. This is structural fat, not the storage fat around organs, and diet helps maintain its integrity.
Omega-3s lead the list
Most people get enough omega-6 but not enough omega-3. Fish is the top source, with chia seeds, walnuts and soybeans as plant options; the discussed range is above 1.5 g and ideally 2–3 g of EPA per day.
Choline feeds the focus system
Choline is the precursor for acetylcholine, the neuromodulator behind focus and concentration, and the same pathway many Alzheimer's treatments target. Egg yolks are the richest source; the general target discussed is 500–1,000 mg per day.
Creatine works in the brain, not just muscle
Creatine can be used as a brain fuel source and shows evidence for improving cognition, particularly in people who don't get it from animal foods. Roughly 5 g per day of creatine monohydrate is the threshold discussed.
Anthocyanins from dark berries
Blueberries, blackberries and black currants contain anthocyanins with reasonable data behind them. Whether the effect is direct on neurons or via lowered inflammation isn't settled, but a cup or two most days is the pattern described.
Glutamine and the gut's satiety signal
Glutamine-sensing neurons sit in the mucosal lining of the gut and send satiety signals to the brain when they detect it, which may offset sugar cravings. Cottage cheese, protein-rich foods, beans, cabbage and spinach all supply it.
Neuropod cells report on your food before you know it
Neurons in the gut tuned to amino acids, sugars and fatty acids send signals via the nodose ganglion that trigger dopamine release. This is a subconscious quality report that drives you to seek more of whatever produced it.
Taste preference is soft-wired
Some preference is hardwired — most children like sweet — but the association between a flavour and its metabolic payoff is learned and can be re-conditioned. That is the leverage point for changing what you find appetising.
Practical takeaways
7- 1
Cover omega-3 intake first 5:40
If fish rarely appears on your plate, look at chia seeds, walnuts and soybeans, or discuss an EPA source with your doctor. The range discussed is 1.5–3 g of EPA per day.
- 2
Egg yolks are the simplest choline lever 9:40
Whole eggs are the richest dietary source of choline; potatoes, nuts, seeds, grains and fruit contribute smaller amounts. The general target mentioned is 500–1,000 mg per day.
- 3
5 g of creatine monohydrate as a baseline 12:10
Huberman describes taking 5 g daily as a long-standing baseline rather than seeking creatine out through extra meat. It's the threshold associated with the cognitive findings he cites.
- 4
Make dark berries a routine, not an event 15:10
A cup or two of blueberries, blackberries or black currants most days is the pattern described for anthocyanin intake — frequency matters more than quantity in one sitting.
- 5
Food first, supplements as a top-up 20:40
Every compound on the list can be obtained from food; supplementation is a way to reach the higher end if that suits you. Check with your doctor before adding or removing anything.
- 6
Keep diet drinks away from meals 27:40
Pairing a non-caloric sweetener with glucose-raising food conditions a stronger insulin response to the sweetener alone later on. If you enjoy diet soda, drink it away from food.
- 7
Pair a good food with a metabolic reward 31:10
To learn to like a brain-supporting food you currently don't, eat it alongside something that raises brain metabolism. The described window for a shift in subjective taste is about 7 to 14 days.
Topics & chapters
17What this episode covers
Food and the brain: what supports focus, brain health and long-term cognition. Huberman frames both halves — what to eat, and why you want what you want.
The three signals behind food choice
A subconscious gut signal about nutrient content, metabolic accessibility to the brain, and belief about what a food will do for you.
Why fat comes before fuel
Before discussing glucose as fuel, Huberman argues for the elements that let neurons exist and stay healthy — and that means fat.
Structural fat and the neuronal membrane
The double-layered membrane bounding brain cells regulates their electrical activity, and it's built from structural rather than storage fat.
Essential fatty acids: EPA and DHA
Most people get enough omega-6 but not enough omega-3. Sources, and the 1.5–3 g per day EPA range discussed.
Phosphatidylserine
Abundant in meat and fish, and available as an inexpensive lipid-like supplement that mimics what the food provides at higher concentration.
Choline and acetylcholine
Choline feeds acetylcholine synthesis, the basis of focus. Egg yolks lead the sources; 500–1,000 mg per day is the general target discussed.
Creatine for the brain
Creatine as a brain fuel source, its link to frontal circuits tied to mood and motivation, and the 5 g per day threshold.
How Huberman uses supplements himself
He treats EPA, creatine and alpha-GPC as a baseline insurance policy rather than chasing these compounds through extra meat.
Anthocyanins in dark berries
Blueberries, blackberries and black currants, the data behind them, and why the mechanism — direct or anti-inflammatory — isn't settled.
Glutamine and sugar cravings
Where glutamine comes from, the 1–10 g supplementation range people use, and the gut neurons that signal satiety when they sense it.
Food first, supplements second
Everything on the list can come from food; supplements help reach the higher end. Check with your doctor before changing anything.
Taste on the tongue, perception in the brain
The five basic tastes, transduction on the tongue, the gustatory nerve to the brainstem, and the insular cortex as the seat of interoception.
Neuropod cells and the dopamine loop
Gut neurons tuned to amino acids, sugars and fats signal via the nodose ganglion and trigger dopamine — a subconscious report on food quality.
Artificial sweeteners and conditioning
The experiments: sweet plus glucose raises dopamine, non-caloric sweet doesn't at first, and pairing the two conditions a later insulin response.
The belief effect: Alia Crum's milkshakes
Identical shakes produced different glucose, insulin and satisfaction responses depending on what people were told they contained.
Rewiring what you find tasty
Pair a brain-supporting food with something that raises brain metabolism; 7–14 days is the described window. Closing note on food wars and the review 'Rethinking Food Reward'.
