The 11 Best Berberine Supplements of 2026, According to Dietitians

Research suggests berberine may help support blood sugar control, improve insulin sensitivity, and lower cholesterol. It may also play a role in glucose metabolism and menstrual regulation in people with polycystic ovary syndrome (PCOS), according to Vanessa Imus, RD, of Integrated Nutrition for Weight Loss in Bothell, Washington.

You may have seen it dubbed “nature’s Ozempic,” but experts caution against thinking of it as a quick fix. “It may be helpful in some cases, but it should not replace a balanced diet, lifestyle changes, or medical treatment,” says Olayide Adejumobi, RD, LD, of NourishBites Wellness in Dallas, Texas.

That’s especially important because berberine isn’t risk-free. It can cause digestive side effects and interact with certain medications, says Pam Hartnett, MPH, RDN, of Pam Hartnett Coaching, LLC, in New York City.

Like most supplements, quality varies widely. Experts recommend choosing products that are independently tested for quality, appropriately dosed, and clearly labeled so you can easily understand the exact form and dose you are taking. To help you find the safest options, we worked with the Everyday Health team and nutrition experts to evaluate a range of popular berberine supplements. Here are the ones we recommend.

• Best for Weight Loss: SoWell Balanced Berberine

To select this list of the best berberine supplements, we asked six registered dietitians for their top picks and what they look for in a quality berberine supplement.

Dose: We prioritized berberine supplements with doses shown to be clinically effective in studies or products that contain ingredients shown to enhance absorption in lower doses. “Common doses range from 500 to 1,500 mg per day, divided into multiple doses,” says Stefani Stewart, RD, founder of Stefani Stewart Nutrition. We looked for supplements with this minimal dose or recommended multiple doses per day to meet this effective dose.

Absorption: We screened for berberine supplements with optimal absorption, like those with a berberine phytosome complex, so you can put more of it to use.

Intended use: We narrowed down the best berberine supplements for each category based on dose, ingredients, and overall effectiveness for different uses. This included berberine combined with ingredients such as probiotics for gut health or turmeric for inflammation.

Third-party or independent lab testing: We always strive to find third-party tested supplements that meet the highest quality, potency, and safety standards. Unfortunately, most berberine supplements are not third-party certified, but we did include a few on this list.

Supplement companies may choose not to seek third-party certification, which is a lengthy process that can be costly. Many companies rely on expert validation from healthcare experts, brand loyalty, and building customer trust instead of third-party testing to validate the quality of their products.

If the products were not third-party certified, we prioritized berberine supplements that underwent extensive in-house lab testing and companies that are transparent when sharing results and follow good manufacturing practices for quality control.

When shopping for a berberine supplement, there are a few key things to look for:

• Potency You’ll want a dose that matches those seen to be effective in research. “Choose a supplement that contains at least 500 mg berberine per pill. Otherwise, you may end up taking several pills to get the desired health benefit,” says Imus.
• Quality Certifications “When looking for a berberine supplement, choose a supplement that has been third-party tested or certified,” says Younkin. While most berberine supplements don’t fit this bill, a handful of our picks do. Another reputable certification is CGMP certification, which also requires a product to meet stringent regulations and quality standards during the manufacturing process.
• Potential Allergens and Other Ingredients Check the dose and the other ingredients, like chromium or cinnamon, says Younkin, “to ensure it aligns with your health goals and doesn't contain any ingredients you are allergic to, or that could interact with medications you take.”
• Price Ensure that the berberine supplement you choose fits your budget, since you’ll need to take it consistently and long enough to experience its potential benefits. Prices vary based on the product, but many companies offer discounts on your first order or when you buy in bulk.

“Several human studies have found that berberine can help improve cholesterol levels, including lowering LDL (the “bad” cholesterol) and triglycerides,” says Hartnett. “These changes may help support heart health and are one reason berberine is sometimes studied in people with conditions such as heart disease, high cholesterol, insulin resistance, or type 2 diabetes.”

Hartnett also emphasizes the importance of a healthy lifestyle in combination with berberine, though. “What you eat most days, how active you are, and how well you sleep all play a key role in blood sugar and insulin management,” she says. “Berberine may help fine-tune that system, but it isn't a substitute for those everyday habits.”

The medication interactions are important to be aware of, though. “I tell my patients that the berberine itself is not the biggest concern. It's how it interacts with other medications,” says Nneoma Oparaji, MD, DipABLM, ABOM, a Houston, Texas-based physician. Dr. Oparaji adds that because berberine can affect blood sugar, liver enzymes, and how certain medications are metabolized, it’s especially important to talk to a healthcare provider before starting it, particularly if you take prescriptions for diabetes, blood pressure, or cholesterol.

Everyday Health recommends speaking with your doctor before adding any supplement to your diet to make sure it is safe and appropriate for your individual health needs. Berberine supplements are considered safe for most people. But people who are pregnant, breastfeeding, or have a history of liver disease shouldn’t take berberine, as there’s not enough evidence of its safety for those in this population. Berberine supplements can also reduce blood sugar, which may be exacerbated if you’re already taking blood sugar-lowering medications like metformin or insulin.

In addition, like all supplements, berberine’s safety and effectiveness is not strictly regulated by the U.S. Food and Drug Administration (FDA), so it’s important to consult a qualified healthcare expert when making your decision.
