Brain & Mood Protocol
Hyman's UltraMind idea in practice: support mood and cognition by fixing the body's inputs first, the right fats, B vitamins, vitamin D, magnesium and gut health, alongside (never instead of) professional care.
Hyman frames the brain as an organ connected to the rest of the body, so his approach to mood, focus and brain fog starts with nutrition and lifestyle: eat brain-supportive fats, correct common deficiencies (omega-3, B vitamins, vitamin D, magnesium), support the gut-brain axis, and add calming nutrients. The supplements below are a brain and mood support stack you can follow together or buy item by item. This is support for a healthy brain, not a treatment for any mental-health condition.
Why it works▼
Feed the brain
The brain is mostly fat and highly sensitive to what you eat.
Take EPA/DHA omega-3
Structural for neurons and supportive of mood and cognition.
Add a methylated B-complex
B12 and folate deficiency impair mood and brain function.
Cover vitamin D3
Low vitamin D is linked to low mood and cognitive decline.
Add magnesium before bed
Calms the nervous system and supports neurotransmitter function.
Take a quality multivitamin
Most people are low in at least one nutrient the brain needs.
Support the gut
Gut health influences mood, inflammation and brain function.
Add L-theanine
Supports a relaxed but alert state.
Add rhodiola
An adaptogen that supports resilience under stress.
Sleep, exercise, light and connection
These are some of the most powerful, no-cost inputs for mood and brain health.
- Low mood, brain fog or stress (alongside professional care)
- People optimising focus and cognition
- Anyone rebuilding after burnout
- Those correcting common nutrient gaps
- Many of these supplements are available through Dr. Hyman's own curated store (drhyman.com); he has a commercial interest in them
- This is nutritional and lifestyle support for a healthy brain, not a treatment for depression, anxiety or any psychiatric condition, and not a substitute for professional mental-health care; if you are struggling, please work with a qualified clinician
- Do not stop or change prescribed psychiatric medication on your own, and note that several supplements interact with antidepressants; in particular 5-HTP and GABA are sometimes discussed for mood but can be dangerous with SSRIs, SNRIs or MAOIs (serotonin syndrome), so we do not dose or sell them here, discuss with your doctor
- Get vitamin D and B12 tested and dose with your doctor rather than guessing
- Supplement doses are general ranges from his public work; follow label dosing and check interactions
