Dr. Daniel Amen on Brain Health: Daily Habits, Supplements, Food, and Calming a Busy Mind

High-Level Overview

Mel Robbins invites psychiatrist Dr. Daniel Amen, who has spent 40 years in practice and whose clinics have performed some 200,000 brain scans, to give listeners what she frames as a free appointment with a leading brain-health expert. His central message is simple and hopeful: the physical functioning of your brain creates your mind, so caring for the organ itself is the most direct route to better mood, focus, memory and decision making. He rejects the term "mental illness" as stigmatizing and prefers to talk about brain health, arguing that the brain is plastic and can improve "even in a matter of months."

The tone is upbeat, practical and often funny. Robbins plays the eager student with a pen in hand, repeatedly asking for the smallest doable step, and Amen answers with quick, concrete lists: morning phrases, bedtime reflections, supplements, foods, a breathing pattern, and a single question to carry around in your head. The conversation moves from a brain-health 101 to neurotransmitters, then to stress, negative thinking, tiredness, food and memory, and closes with the one habit Amen would leave everyone with.

The Discussion Explores:

• Why Amen distinguishes the brain from the mind, and why he wants to replace "mental illness" with "brain health"
• His three-step framework: brain envy, avoiding what hurts the brain, and regularly doing what helps it
• Tiny habits for the start and end of the day, developed with Stanford's BJ Fogg
• A high-quality multivitamin and omega-3 fatty acids as baseline supplements
• Serotonin, dopamine and cortisol, and natural ways to balance them (light, exercise, cold, drip dopamine)
• The 15-second breath and questioning automatic negative thoughts to calm a busy brain
• A biological, psychological, social and spiritual checklist for chronic tiredness
• Brain foods, a daily brain-healthy hot chocolate, and protecting memory through blood flow

Deep Dive into Main Ideas

Your Brain Creates Your Mind

Amen opens by explaining that long ago he came to hate the term mental illness: "It's stigmatizing and it's wrong." What people suffer from, in his view, are brain health issues, and if you get the brain healthy, the mind follows. He points to Alzheimer's disease as the clearest example: scans of people with the disease look "wildly damaged," and the person is no longer fully themselves because the organ that produces the self has been hurt.

The practical upshot is that anyone can improve their brain, and quickly. "If you get better sleep tonight, your mind can be better tomorrow. If you get drunk tonight, your mind's going to be worse." He describes the brain as involved in everything you do, how you think, feel, act and relate to others. When it works right, you work right; when it is troubled, you become sadder, sicker and poorer because your decisions are worse. He jokes that in Newport Beach, where he lives, people care more about their faces and bodies than their brains, even though it is the brain that makes you attractive, happy and purposeful.

Brain Envy, Avoidance, and the Mother of All Tiny Habits

Amen boils brain health down to three steps. First, brain envy: you have to genuinely care about the organ between your ears. Second, avoid anything that hurts it; he quips that most second graders would score 90% on a list of 100 things that damage the brain. Third, regularly do things that help it.

To make the third step stick, he worked for six months with BJ Fogg, who runs a lab at Stanford on how people change, developing tiny habits. The "mother tiny habit" takes three seconds: whenever you go to do something, ask whether it is good for your brain or bad for it. If you answer with information and love, love of yourself, your family and your mission, he says you will start making better decisions.

His own daily bookends are simple. Each morning he tells himself "today is going to be a great day" and then asks why, which directs the mind into a positive state. Each night, after a prayer, he asks "what went well today" and goes on a treasure hunt through the day from the moment he woke up. He has done this for seven or eight years, including the awful night his father died, and credits the habit with helping him through it. "The brain is lazy. It does what you nudge it to do."

Two Supplements Everyone Should Consider

Asked for the one supplement everyone should take, Amen names a high-quality multivitamin (he mentions that he makes one) and cites a new study in which people with memory problems who took a high-quality multivitamin had better memory within months. He notes the study compared it against placebo and cocoa extract, and "it wasn't the chocolate. It was the multiple vitamin," while adding that he never makes disease claims with supplements.

The second is omega-3 fatty acids, which he says are good for the heart, brain, hair, skin and eyes. His reasoning for the brain: "25% of the nerve cell membranes in your brain are made up of omega-3 fatty acids," so a deficiency slows the brain, and low levels have been associated with problems ranging from depression to dementia to ADHD. Robbins confesses she has been dropping the ball and promises to report back after taking both consistently.

Serotonin, Dopamine, and Why You Should Drip, Not Dump

Amen describes serotonin as important for happiness, flexibility and feeling respected. When it is low, people worry, get stuck on negative thoughts, become argumentative and get upset when things do not go their way, which can look selfish but is really rigidity. Sunlight and bright light help, which is why shorter winter days matter. He explains that the gut makes about 90% of the body's serotonin, but the brain makes its own from the amino acid tryptophan, and that pairing tryptophan-rich food with a carbohydrate (he suggests turkey and sweet potatoes) helps drive it into the brain. Serotonin and dopamine counterbalance each other, which is why some patients on Prozac told him they were less depressed but also less motivated.

Dopamine, he says, is "the molecule of more," and the more you get, the more you want. Phones, social media, video games and constant texting are "wearing out our dopamine centers," and cocaine, alcohol, nicotine, vaping, scary movies and even falling in love all dump it. His rule is "drip dopamine don't dump it": small bursts rather than big splashes. Signs of low dopamine include being tired, sad and unmotivated. To raise it naturally, he finishes every shower with about two minutes of full cold water, since cold exposure has been shown to increase norepinephrine and dopamine. He adds that dopamine tends to be higher in the morning and serotonin in the evening, but everyone's rhythm differs, so know whether you are a morning, lunch or night person and focus when your energy peaks.

Light, Exercise, and Strength as Brain Reserve

For mornings, Amen recommends a bright light therapy lamp of 10,000 lux, placed about an arm's length away (not stared at) for 20 or 30 minutes, which he says can improve dopamine, energy, mood and cognition. Exercise boosts both serotonin and dopamine; he suggests walking like you are late for 45 minutes, four or five times a week.

At 68, he is convinced strength matters too: the stronger you are as you age, the less likely you are to get Alzheimer's, and frailty kills older people almost more than anything else. He calls strength training absolutely critical for men and women because muscles are your protein reserve. He extends the idea to "brain reserve": two people can have the same car accident and have very different outcomes depending on how healthy their brains were going in, so every day you should be boosting your reserve.

Cortisol and the 15-Second Breath

Cortisol, made by the adrenal glands, helps manage stress and inflammation, but when chronically high from stress and negativity it puts fat on the belly and shrinks the hippocampus, the brain's major memory center. To bring it down, Amen recommends meditation, prayer, hypnosis (which he has used with patients for 40 years) and a regular relaxation practice, plus a question for stressful moments: is this worth killing brain cells for?

His favorite tool is the 15-second breath, which he says can end a panic attack "in two minutes or less." Breathing out twice as long as you breathe in triggers an automatic relaxation response: four seconds in, hold for a second and a half, eight seconds out, hold for a second and a half, and repeat. It shifts the body from the sympathetic, fight-or-flight state into a parasympathetic one, and with practice creates a pathway of relaxation in the brain. He illustrates the stress state with a story of two pit bulls charging him and his white shepherd on a beach, which left him bitten and still occasionally triggered. He used a session of EMDR to process it, prompting Robbins to share that EMDR has helped her with childhood trauma over two years of therapy.

Directing Your Thoughts: "Is It True?"

To calm a busy brain, beyond breathing, Amen urges people to direct their thoughts. "I was 28 years old before I'd learned I didn't have to believe every stupid thing I thought," he says, recalling a professor's lesson during his psychiatric residency at Walter Reed. As one of seven children in a chaotic family, his mind used to torture him. Now he writes down negative thoughts and asks whether they are true, aiming to be the director of his own mind rather than letting ancestors, parents, the news or office gossip direct it.

If he ever got a tattoo, he says, it would read "is it true." Thoughts are like the weather; "It's not the thought you have that makes you suffer. It's the thought you attach to that makes you suffer." Robbins applies this to her own recent illness, when she told herself her husband Chris was annoyed at caring for her and that people were mad she had cancelled things, stories that made her feel terrible and were not true.

When You're Tired All the Time

Amen's first advice for chronic tiredness is to get your thyroid checked; fatigue can also come from anemia, low iron, infection, gut or hormone problems. He looks at people through four circles: biological, psychological, social and spiritual. Psychologically, automatic negative thoughts can drive cortisol and leave you wiped out. Poor sleep matters, and loud snoring, stopping breathing at night or daytime exhaustion warrant a sleep apnea check. Socially, conflict with loved ones and holding on to hurts drain energy, which is why he is a huge fan of forgiveness. Spiritually, a stronger sense of purpose opens up energy.

Brain Foods, Hot Chocolate, and Protecting Memory

His five best brain foods are wild salmon for omega-3s, berries (especially blueberries, which he calls brain berries), nuts and seeds (linked to lower rates of depression and dementia), leafy greens for fiber and magnesium, and his favorite, raw cacao. He makes brain-healthy hot chocolate almost daily: a heaping teaspoon of raw cacao in about 12 ounces of heated unsweetened organic almond milk, a few drops of Sweet Leaf liquid chocolate stevia, blended.

On memory, he warns that 50% of people 85 and older will be diagnosed with dementia, and that protecting the brain means preventing or treating 11 major risk factors, summarized in his BRIGHT MINDS mnemonic. The most important may be B for blood flow: avoid what steals it (caffeine, nicotine, being sedentary, heart disease) and do what enhances it (walking, raw cacao, beets, ginkgo, cinnamon, oregano). He also lists what he would never do: say everything he thinks, purposefully stay up late, eat everything he wants, or medicate based only on symptom clusters without looking at the brain. For seasonal low mood, he recommends morning bright light, exercise, limiting caffeine and turning off blue light after dark, since it suppresses melatonin.

Conclusion

Dr. Amen's message is that a better mind starts with a healthier brain, and that the steps are small and within reach: care about your brain, stop doing what harms it, and add simple habits that help it. Morning intentions and nightly gratitude, a multivitamin and omega-3s, bright light, brisk walking and strength training, drip-not-dump dopamine, the 15-second breath, and the habit of asking whether a thought is true all build what he calls brain reserve. His parting advice ties it together: at every decision point in your day, ask whether what you are doing is good for your brain, because if you start making good decisions for your brain, he says, everything else in your life will be better.
