Essentials: Developing a Rational Approach to Supplementation for Health & Performance

Welcome to Huberman Lab Essentials. I’m Andrew Huberman, professor of neurobiology and ophthalmology at Stanford School of Medicine. Today is supplements, and a rational way to decide whether they belong in your life. The hierarchy is behaviors first—morning light and exercise—then nutrition, then supplementation, and prescription drugs when appropriate with a board-certified physician. I’m not a clinician and don’t prescribe; I review science. Consult a trusted physician before changing behaviors, nutrition, supplements, or medications.

No supplement fixes poor nutrition or replaces better living. Ask where there is a need: sleep, daytime alertness, nutrition, and budget. For limited diets, fasting, or heavy physical or mental demands, a foundational vitamins-and-minerals formula, potentially with digestive and gut-support compounds, can make sense. Take vitamin-mineral products with food if they upset your stomach.

For sleep, start with the obvious: avoid late caffeine and, for most people, don’t eat right up until bed. Match the tool to the problem. If you wake and cannot return to sleep, myo-inositol is one possibility. If intense dreams wake you, theanine may not be for you. For trouble falling asleep, magnesium threonate or bisglycinate and apigenin are options. Try one ingredient for about a week without changing the rest of your protocol, and stop if adverse effects occur. I’m not a fan of melatonin: typical products often deliver far beyond naturally occurring levels.

Hormone support is not a shortcut around nutrition and behaviors. Morning light helps set cortisol high early, supporting alertness. Fadogia agrestis and tongkat ali may affect hormone-related outcomes, but response is individual. With fadogia, respect the dose and cycle it; high doses may be toxic. Hormone-active supplements can feel different across phases of the menstrual cycle.

For focus, distinguish alertness from tighter focus. Caffeine is potent; alpha-yohimbine can provoke anxiety. Alpha-GPC and L-tyrosine may sharpen focus without the same jittery quality, but explore them separately before combining them. I find L-tyrosine powerful, but I crash afterward—that’s why careful self-testing matters. For one broad single-ingredient option, I’d choose high-quality omega-3s, with more than one gram of EPA per day. Supplements are one powerful gear in a larger system. Thank you for your interest in science.
