Andrew Huberman on Berberine
14 episodes · 29 references · 2021–2025
- Huberman views berberine as a potent glucose disposal agent on par with prescription metformin, but personally stopped taking it due to severe hypoglycemic headaches - He extensively discusses blood glucose lowering benefits while repeatedly warning about dangerous hypoglycemia when taken without carbohydrates - No specific dosing guidance discussed; no best-practice timing or form recommendations provided
Consumption
- Huberman took berberine during roughly 2012–2015 while following Tim Ferriss's slow carbohydrate diet to buffer blood glucose from high-calorie meals - He reports two distinct experiences: effective glucose disposal when taken with carbs, and severe hypoglycemia when taken without - He ultimately discontinued use due to persistent splitting headaches and hypoglycemic episodes
Benefits
- Berberine dramatically lowers blood glucose on par with prescription drugs metformin and glibenclamide, activating fasting-associated pathways - Reduces insulin levels which promotes fat oxidation, improves insulin sensitivity, and may help prevent insulin-resistance-related hair loss - Lowers cholesterol via liver metabolism, flattens blood glucose response when taken with carbohydrates, and may eliminate canker sores through direct topical application
Cautions
- Taking berberine without sufficient carbohydrates causes profound hypoglycemia — Huberman experienced splitting headaches lasting ~8 hours and needed ~10 donuts to recover - May crush testosterone levels in men who use it chronically to lower blood sugar, similar to metformin - Huberman personally recommends against it for himself, citing brutal headaches and intense carbohydrate cravings from blood sugar drops
“I've taken berberine before and I've had two different very distinct experiences with them.”

“I've tried berberine before. If you take berberine and you have not ingested carbohydrates, many people, including myself, experience a splitting headache.”

“Berberine is kind of the poor man's metformin. It's a tree bark extract that also dramatically lowers blood glucose.”

“Berberine, which comes from a plant, or metformin are compounds that are now in growing use for reducing blood glucose. They are very potent at reducing blood glucose which will reduce insulin.”
How to Lose Fat with Science-Based Tools
“Berberine is very potent at reducing blood glucose which will reduce insulin. Fat oxidation, this conversion of fatty acids into ATP in the mitochondria, is inhibited by insulin.”

“Berberine, which is an over the counter substance will lead to very dramatic reductions in blood glucose. And so they shift you from a fed to a fasted state.”

“I'm going to skip the berberine because berberine gives me brutal headaches and it makes me crave carbohydrates because it drops my blood sugar.”
