There’s a buzz across social media about the supplement berberine and its ability to boost metabolism, balance blood sugar and burn fat. Is this really the magic weight loss pill we’ve all been dreaming of?

Berberine is a golden compound found naturally in plants like turmeric and goldenseal. It has a long history of use in traditional Chinese and Ayurvedic medicine due to its potent health-promoting properties, including anti-inflammatory, antioxidant, and antimicrobial effects.

More recently, berberine has been studied for its effects on health conditions such as diabetes, cardiovascular health, and gastrointestinal issues. However,  there is new research suggesting that it actually may have potential benefits for weight loss as well.

Metabolic Effects of Berberine

Berberine has been shown to have an impact on various metabolic processes in the body. It can activate an enzyme called adenosine monophosphate-activated protein kinase (AMPK), which plays a crucial role in regulating metabolism. Activation of AMPK can promote glucose uptake, increase insulin sensitivity, and enhance fat oxidation.

Appetite Regulation

Some studies suggest that berberine may help regulate appetite and reduce food intake. It can influence certain hormones involved in hunger and satiety, such as leptin and ghrelin, leading to a decrease in appetite and calorie consumption.

Fat Loss

Berberine may inhibit the formation of new fat cells and reduce the accumulation of fat in the body. It has been found to affect genes and signaling pathways involved in lipid metabolism, leading to a decrease in fat storage. Bonus: As fat absorption decreases, cholesterol levels drop too. It’s a win-win and then some.

Insulin Sensitivity

Berberine can lead to a significant decrease in hemoglobin A1C – yet another reason to take for healthy natural blood sugar balancing. Berberine has been shown to improve insulin sensitivity in individuals with insulin resistance or type 2 diabetes. By enhancing insulin sensitivity, it can help the body utilize glucose more efficiently and potentially reduce fat storage.

An American medical journal published a small clinical trial comparing the effects of berberine versus metformin, the world’s most popular oral diabetes drug. After three months on these treatments, blood sugar improved dramatically, and hemoglobin A1C went from an average of 9.5% to 7.5%. Berberine’s effects were identical to metformin’s – and berberine was much better than metformin at lowering cholesterol and triglycerides.

Not All Berberine is Created Equal: berberine vs dihydroberberine

Dihydroberberine is berberine’s more biologically available derivative. That means it’s the purer version of berberine – with greater bioavailability and has less potential for stomach upset. You get the same powerful health impact as berberine, but with smaller doses and fewer side effects. Here are a few of our most trusted berberine supplements.

One important note when buying any berberine product: only purchase berberine from a reputable company, many of the berberine products are spiked with other plants and not nearly as effective.

What is the Best Berberine Dose for Weight Loss?

While the benefits of berberine for weight loss have not been clinically proven in humans, patients who can safely take berberine may see beneficial effects on body weight and body fat with doses ranging from 500-1000 mg per day. Taking berberine on an empty stomach may be more effective in reducing blood sugar levels in some patients.

  • Take up to 1500 mg per day (split throughout the day as necessary)
  • Start titration at 500mg per day and increase as tolerated
  • Higher daily doses will be necessary for weight loss and supporting insulin resistance
  • Duration of therapy should be consistent for at least 3 months 

Possible Berberine side effects

Berberine appears to have low toxicity and does not typically lead to adverse effects at doses under 1500 mg per day. However, some individuals may experience minor gastrointestinal issues, such as upset stomach, diarrhea, gas, and constipation.


While these findings are promising, it’s important to note that the research on berberine as a weight loss supplement is still limited, and more studies are needed to confirm its effectiveness and safety for this specific purpose. It is also worth mentioning that weight loss is a complex process influenced by various factors such as diet, physical activity, and overall lifestyle.

If you are considering using berberine or any other supplements for weight loss, it’s recommended to consult with a healthcare professional or a registered dietitian. They can provide personalized advice, taking into account your specific health condition and goals.
