Essentials: Food & Supplements for Brain Health & Cognitive Performance
Andrew Huberman, Professor of Neurobiology and Ophthalmology at Stanford, discusses science-backed nutrients for brain health and longevity, including omega-3s, creatine, and choline. He also explores how taste, gut signals, and beliefs shape food preferences, offering tools to rewire them for healthier choices.

6 Key Concepts
Structural Fat
The double-layered membranes of nerve cells and other brain cells are primarily made of structural fat, not storage fat. This structural integrity is crucial for healthy neuronal function and for regulating the electrical activity that allows neurons to communicate.
Acetylcholine
A neuromodulator in the brain, often described as an 'electrical highlighter pen,' that is fundamental to focus and concentration. Many treatments for cognitive challenges like Alzheimer's disease aim to enhance the amount of acetylcholine available to neurons.
Anthocyanins
Compounds found in dark-colored, thin-skinned berries (like blueberries and blackberries) that have been shown to improve brain function. Their benefits may stem from direct effects on neurons or from their role in lowering inflammation throughout the body.
Neuropod Cells
Specialized neurons located along the digestive tract that are exquisitely tuned to sense the amino acid, sugar, and fatty acid content of food. These cells send subconscious electrical signals to the brain, triggering dopamine release to motivate further seeking of those foods.
Hardwired vs. Softwired Systems
In neuroscience, 'hardwired' refers to biological systems that are largely immutable, such as an innate preference for sweet tastes. 'Softwired' systems, however, are amenable to change and can be reconditioned, allowing for the reshaping of learned food preferences.
Belief Effect
This effect demonstrates that an individual's subjective belief and thoughts about what a food contains or what it will do for them directly impact physiological measures. This includes responses like insulin release, blood glucose levels, and overall feelings of satisfaction, even if the actual food consumed is identical.
7 Questions Answered
Beyond water, structural fats are crucial for the integrity of neuron membranes. Essential fatty acids like omega-3s (EPA) and phospholipids like phosphatidylserine are key components that support brain health.
Dietary choline is a primary source for acetylcholine, a neuromodulator vital for focus and concentration, acting as an 'electrical highlighter pen' in the brain.
Yes, creatine can serve as a fuel source for the brain and enhance frontal cortical circuits related to mood and motivation. At least 5 grams per day, typically as creatine monohydrate, appears to be the threshold for cognitive benefits.
Neuropod cells in the gut sense the nutrient content (amino acids, sugars, fatty acids) of food and send signals to the brain via the no-dose ganglion, triggering dopamine release that motivates us to seek more of those foods.
Yes, repeated consumption of artificial sweeteners can condition the dopamine system, leading to increased seeking. If consumed alongside foods that raise blood glucose, they can also disrupt blood sugar management by causing increased insulin secretion.
The data suggests that even within a short period of about 7 days, and certainly within 14 days, a food can take on a subjective experience of tasting better to you if you consistently pair it with a shift in brain metabolism.
Yes, the 'belief effect' shows that your subjective thoughts about a food's content or value can directly impact physiological measures like insulin and blood glucose responses, as well as feelings of satisfaction, even if the food itself is identical.
13 Actionable Insights
1. Prioritize Omega-3s (EPA) for Cognition
Consume foods rich in omega-3s or supplement with 1.5-3 grams of EPA daily to support healthy brain function and cognition in the short and long term.
2. Enhance Focus with Daily Choline
Strive to consume 500-1000 milligrams of choline per day, primarily from egg yolks or other sources, to support the acetylcholine pathway crucial for focus and concentration.
3. Boost Cognition with Daily Creatine
Supplement with at least 5 grams of creatine monohydrate daily to provide a fuel source for the brain and enhance frontal cortical circuits involved in mood and motivation, improving cognition.
4. Support Neuronal Function with Phosphatidylserine
Obtain phosphatidylserine from meats and fish, or consider supplementing, as it is directly supportive of neuronal function and brain health.
5. Consume Dark Berries for Brain Function
Regularly eat a cup or two of blueberries, blackberries, or black currants, ideally daily, because their anthocyanins improve brain function and overall well-being.
6. Rewire Food Preferences by Pairing
To develop a preference for healthy foods, pair them with foods that you already like and that cause a shift in brain metabolism; this can make the healthy food taste better within 7-14 days.
7. Adjust Palate, Reduce Palatable Foods
Gradually reduce consumption of highly sweet or savory “super palatable” foods to adjust your palate and dopamine system, making less intense, healthier foods more attractive and rewarding.
8. Reinforce Healthy Eating Through Consistency
Consistently consume healthy foods, especially those that increase brain metabolism and dopamine, as regular intake reinforces their desirability and makes them feel good.
9. Use Glutamine to Reduce Sugar Cravings
Consume glutamine from protein-rich foods or supplement with 1-10 grams daily, as it can signal satiation to the brain and help offset sugar cravings.
10. Avoid Artificial Sweetener & Food Pairing
If consuming artificial sweeteners, do so separately from foods that raise blood glucose levels, as pairing them can disrupt blood sugar management and insulin response.
11. Consult Doctor for Diet/Supplements
Always check with your doctor before starting or removing anything from your diet or supplement regimen to ensure it is safe and appropriate for your individual health.
12. Improve Sleep with AGZ Before Bed
Take AGZ 30-60 minutes before sleep to increase the quality and depth of your sleep, aiding in waking up feeling more refreshed.
13. Hydrate with Electrolytes Daily
Dissolve one packet of Element in 16-32 ounces of water and drink it first thing in the morning and during physical exercise to ensure adequate hydration and electrolyte intake.
3 Key Quotes
Unless one considers the water content of the brain, which is very high, a lot of our brain and a lot of the integrity of the nerve cells, the so-called neurons in our brain and the other types of cells comes from fat.
Andrew Huberman
What your brain, meaning what you are seeking when you eat is not taste, is not dopamine, is not even a rise in blood glucose. What you're seeking, even though you don't realize it because it's subconscious, is you are seeking things that allow your neurons to be metabolically active.
Andrew Huberman
We don't just like sweet foods because they taste good, we like them because they predict a certain kind of metabolic response.

2 Protocols
Rewiring Food Preferences for Healthier Choices
Andrew Huberman- Identify a healthy food you want to consume more of, especially if it's not currently palatable.
- Pair this healthy food with another food that provides a shift in brain metabolism (e.g., a food you enjoy that causes a rise in blood glucose or dopamine).
- Consistently consume this pairing for at least 7 to 14 days.
- Observe that the healthy food will subjectively begin to taste better, as your brain's dopamine system will start to reward its consumption.
Unpairing Artificial Sweeteners from Blood Glucose-Raising Foods
Andrew Huberman- If you consume artificial sweeteners (e.g., diet soda), do so away from any foods that raise blood glucose levels.
- Avoid consuming artificial sweeteners simultaneously with meals or snacks that contain carbohydrates or sugars to prevent disruption of blood sugar management.
