Best Berberine Supplement for 2021 (Reviews & Buyer’s Guide)

Compared to other brands in our best berberine supplements reviews, Nuzena’s Berberine Pure + has the most potent berberine formula (1200mg per serving). Besides its superior potency, this is also a top-notch supplement in terms of quality. For instance, we were impressed that it’s gluten-free, GMO-free, and even suitable for our beloved vegan readers.

Scientific research suggests that Nuzena’s berberine formula can reduce blood sugar levels in people with type-2 diabetes, boost metabolism, and help lower cholesterol levels. With science on their side and being on many top 10 lists for the best berberine supplement of 2019, we had to score this one high.

Furthermore, we must praise Nuzena’s dedication to providing their customers with the highest quality products. Proof of their commitment is the Nuzena Quality Certification that anyone can access on the company’s official website.

All in all, we recommend Nuzena Berberine Pure+ due to its clinically proven ingredients, efficient and pure extracts, and allergen-free formulas. As a bonus, all of their products are sustainably sourced.

What makes Whitaker Nutrition the best berberine brand overall, besides 35 years of experience, is a successful clinical study that proves this product is excellent for supporting blood sugar health. Added calcium, chromium, and cinnamon make the blend even more powerful.

Moreover, the pills also provide support for healthy total and LDL cholesterol levels. Finally, the blend also enhances liver health.

Berberine reviews for diabetes reveal that many doctors prescribe this supplement to their diabetic patients and get very quick results, with patients reporting reduced glare sensitivity and normalized insulin resistance.

However, if you don’t follow your doctor’s recommendations or manufacturer’s instructions, you might end up with diarrhea. This isn’t a catastrophic issue and can be easily avoided by not exceeding the recommended dosage.

Thorne Research Berberine-500 has stellar customer reviews claiming that this is the best natural solution for regulating blood glucose levels. Additionally, Thorne offers a Berbecap option to help balance cholesterol, making it the best berberine supplement with 500mg capsules.

The Berberine-500 formula offers 85% Berberis Concentrate Berberine HCl derived from Barberry extracts. Furthermore, if you suffer from food intolerances or allergies, this could be the brand for you! It’s yeast-free, dairy-free, soy-free, corn-free, and sugar-free. Also, there’s no magnesium stearate (a common food additive) in this supplement.

Each serving (two capsules) will give you 1000mg of pure berberine extract, and it’ll last you for up to one month. Compared to other similar products on the market, this is a moderately high dosage. So, make sure to read the instructions or the information on the official website for the correct dosage.

The only downside is that this supplement is a bit too strong and may keep you awake for longer than you’d like.

Amazing Nutrition Berberine offers 500mg of Berberine Hydrochloride (HCl) for glucose metabolism support and weight loss management. Each 1000mg serving consists of two easy-to-swallow gelatin capsules free of common allergens, including peanuts, wheat, soy, fish, eggs, shellfish, and dairy.

There are many reasons why we recommend purchasing this high quality berberine supplement brand. Not only is the quality outstanding, but the manufacturer is also extremely transparent when it comes to the ingredients of their product.

There are many positive ratings about this brand’s ability to help with high blood sugar, lethargy, and weight loss. But what struck us was the many women who swear by this product’s ability to alleviate their symptoms of polycystic ovary syndrome (PCOS). Therefore, we believe Amazing Nutrition is the best berberine supplement with 500mg capsules to treat women with PCOS.

The only negative comments that we spotted were that some users complained that the capsules had a slightly unpleasant odor.

If you’re entirely new to the world of supplements, we recommend choosing berberine with lower milligrams per capsule. This way, you can easily adjust your body to the strength and dosages. Swanson Vitamins Berberine with 400mg of berberine HCl per serving could be the perfect brand for you.

However, don’t let the low dosage fool you. This premium berberine supplement for diabetes contains 97% berberine HCl derived from berberis aristata root. Even though the dosage is lower than other products, its concentration is high, so you should be careful when using it daily. As always, it’s best to consult with a healthcare professional for expert advice.

Each of Swanson’s products is manufactured in a GMP-certified facility, ensuring complete purity and incredible potency. Moreover, every Swanson product gets tested by an independent and third-party laboratory.

All in all, there are many reasons why we recommend this organic berberine supplement for our readers. In addition to this product’s impressive purity, we also loved its bargain price.

The only negative claims were that some customers felt achieving noticeable benefits took time with this product. So, don’t be discouraged if you don’t notice any significant changes when first beginning supplementation.

Berberine HCl Capsules by Nutricost are one of the best-selling supplements that you can get for a mere $0.35 per serving. The amount of berberine HCl is relatively low compared to similar products, so it’s a good supplement for beginners. Furthermore, we believe this is an excellent option for people trying to lose weight.

According to many berberine supplement reviews, each container of this supplement will last you up to two months of continuous use. This means that you won’t have to worry about restocking your supply too frequently.

Besides the exceptional production quality, satisfied customers raved about the kind and helpful customer service they received. Someone is always available to answer your questions about what many deem the best berberine on the market.

Lastly, this is a third-party lab-tested, non-GMO, gluten and allergen-free product. The only drawback we came across was that the ingredients include vegetable magnesium stearate, a food additive that many comparable products successfully evade.

Sunergetic Premium offers you a potent 1200mg dose of berberine HCl extract per serving, consisting of two easy-to-swallow vegetable capsules.

Although this brand provides many of the usual benefits of berberine supplements, we believe that it’s the most suitable for our readers who want to support overall wellness and cardiovascular health.

Most studies on berberine indicate a recommended daily dosage of between 1,000 and 1,500 milligrams. Therefore, Sunergetic is a terrific option as just two capsules a day will put you well within this suggested range. Furthermore, many satisfied customers spoke of how they purchased this product to get their blood sugar levels under control and were completely satisfied with the results.

Not only are all Sunergetic products manufactured in an FDA-registered facility, but they’re also GMO-free, yeast-free, corn-free, dairy-free, soy-free, and preservative-free. So, for just over $20, you’ll receive one of the highest-quality berberine brands on the market.

The only negative thing that we can say about Sunergetic Premium is that the exact concentration purity is not listed on the label. However, Sunergetic is a trustworthy brand that has been in the natural supplement business since 2012.

If you’re having complications due to small intestinal bacterial overgrowth (SIBO), this is likely the best brand of berberine supplement to provide you with the relief that you need.

Integrative Therapeutics’ unique formula contains a blend of extracts from three different plants, Oregon grape, goldenseal, and barberry. Not only does this mix of multiple extracts offer berberine, but it also provides other beneficial compounds such as hydrastine.

Moreover, research shows that hydrastine in goldenseal is beneficial for skin health. Therefore, we believe this is the best berberine mix supplement and a superb choice for people looking for healthier skin and anti-aging benefits.

Most importantly, this berberine complex doesn’t contain animal by-products, so it’s suitable for our vegan and vegetarian readers. Furthermore, it’s gluten-free, soy-free, dairy-free, artificial color and flavor-free, wheat-free, and preservative-free, making Integrative Therapeutics a superb option for people with food allergies or intolerances.

The only possible disadvantage of this formula is that it contains a complex mix of extracts instead of only berberine HCl. If this bothers you, we suggest choosing another quality supplement from our list of berberine supplement reviews. Either way, for the overall value, we believe this is an exceptional product to consider.
