Carbivore: a capsule for the carbs you eat?
No trial of it — and we could not find what is in it.
Carbivore, from CleverPro by Tora Labs, is sold as a “glucose disposal agent” for people who eat carbs and do not plan to stop. Its bottle promises to block carbs, improve insulin sensitivity and curb cravings.
Short answer: we found no trial of Carbivore. A second ad names its main ingredient — dihydroberberine (GlucoVantage), a form of berberine — though its full label is still not public where we could find it. Dihydroberberine’s one human trial was a pilot of five men: it raised blood berberine more than plain berberine, and did not change blood sugar after a carb-heavy meal. Berberine itself is graded on our longevity page.

What the research shows
Grades are calculated from the studies listed, by fixed rules.
- Dihydroberberine puts more berberine into the blood than ordinary berberinePromising
In a pilot of five men, 100 mg of dihydroberberine raised blood berberine more than 500 mg of berberine. Five people is very few, and an author advises a dihydroberberine supplier.

- Dihydroberberine lowers blood sugar after a carb-heavy mealNo real evidence
In the same pilot, blood sugar and insulin after a meal of glucose and white bread did not change. The authors put that down to the short dosing and healthy men; it is untested, not shown.
