Berberine is another naturally-derived compound that’s recently gone TikTok-famous for its supposed effects on weight loss. The compound can be derived from various plants, and many online influencers suggest it’s a natural weight loss miracle.
But is berberine actually proven in research studies to cause weight loss, or is it another passing gimmick? Does it cause side effects? How do real users who took berberine for weight loss describe its effects? And what retailer sells the best quality berberine?
In this article we’ll answer all of these questions and more, as we analyze medical studies on berberine and weight loss to give our take on whether the supplement is likely to be effective, or if it’s a waste of money.
We’ll feature unsponsored user reviews including before-and-after images, discuss potential side effects of berberine and share our top berberine supplement recommendation.
Does Berberine Actually Cause Weight Loss?
Berberine has been studied in various clinical trials for its effects on weight.
A 2020 meta-study analyzed results from 12 clinical trials on berberine and weight loss. The researchers reported that trial participants taking berberine lost an average of 4.6 pounds.
The duration of the trials varied from 1 to 24 months, but most of the trials were 3 months long. This suggests a potential annualized weight loss of 18.4 pounds from berberine supplementation.
A medical review published in the Biomedicine & Pharmacotherapy journal analyzed test tube studies, animal studies and human studies to determine the effects of berberine on weight.
The study authors concluded that berberine caused modest weight gain on average, and also had favorable effects on cholesterol and blood sugar.
A 2012 clinical trial reported that berberine caused an average weight loss of five pounds over 12 weeks in obese subjects. This suggests a potential annualized weight loss of 20 pounds.
The total dose used in the above-linked trial was 1,500 milligrams (mg) per day split across three daily dosings of 500 mg.
Overall, we consider the research on berberine for weight loss to be convincing. We do not recommend taking berberine as a standalone treatment for obesity or any other medical condition, but it may be worth consulting with a doctor about.
Before discussing potential side effects of this compound, we’ll feature some unsponsored berberine user reviews in the next section.

Does Berberine Cause Side Effects?
Berberine can cause side effects such as gastrointestinal distress, constipation or diarrhea according to a medical review published in the Phytotherapy Research journal.
However, side effects don’t appear to be severe when the supplement is dosed appropriately.
A medical review published in the LiverTox journal stated the following about berberine supplementation:
“Side effects are few and largely mild and transient.”
Berberine can interact with prescription medications and cause dangerous side effects according to MedLinePlus, so it’s important that patients discuss berberine supplementation with a doctor who’s aware of any prescription medications they’re using.
Overall, we consider berberine unlikely to cause side effects in otherwise healthy individuals.
