In addition to berberine, it also includes cinnamon and chromium. Cinnamon ensures normal insulin sensitivity while chromium improves bioavailability.

Berberine is a bioactive compound usually extracted from the shrubs of the genus Berberis, commonly known as barberries. Taken as a supplement, berberine has been shown to reduce insulin resistance and improve biomarkers of type 2 diabetes. In fact, berberine may be as strong as prescription drugs used for the same purpose.

Berberine has the ability to switch a metabolic enzyme called AMPK (AMP-activated protein kinase) on. This enzyme is involved in controlling the use of glucose and fatty acids for energy. Berberine’s mechanism of action, therefore, helps regulate fat and sugar levels in the body.

Benefits Of Berberine

In short, berberine improves every parameter associated with insulin sensitivity, glucose metabolism and type 2 diabetes. In type 2 diabetes, cells in the pancreas develop resistance to increasing blood glucose levels by refusing to respond to insulin — an important hormone for reducing glucose levels.

A systematic review found that berberine strongly decreases blood glucose, and also causes a small but consistent decrease in insulin levels. Similarly, a study found that berberine increases insulin sensitivity, reducing insulin resistance. 

That same review found that berberine also lowers hba1c, or glycated hemoglobin — a marker of excessive blood sugar levels.

If you have consistent high blood glucose levels, over time this can damage your health, including causing peripheral neuropathy and severe dehydration, so berberine’s ability to improve glucose metabolism is very promising.

Berberine also lowers total cholesterol and restores a healthy triglyceride balance by decreasing LDLs and slightly increasing HDL cholesterol. This reduces the risk of cholesterol building up in your arteries and decreases the likelihood of developing coronary heart disease.

All in all, berberine is comparable in effectiveness to metformin and glibenclamide, the first-line prescription drugs for fighting type 2 diabetes. Based on studies, the optimal dosage of berberine seems to be 500 mg, taken 2-4 times a day before each meal.

Best Brand Of Berberine

Wondering what some of the best brands for berberine are? Let’s quickly review 3 of the best berberine supplement brands and discuss why these brands are considered to be authorities in this niche.

Thorne Berberine

Thorne is recognized as one of the best supplement brands around today and is commonly recommended by health professionals and professional sports leagues. It’s been given an “A” rating by Australia’s Therapeutic Goods Agency, a regulatory institution with some of the highest standards, and is regulated by the U.S. Food and Drug Administration.

Thorne is dedicated to the use of clean ingredients only and provides an extensive list here of the ingredients it avoids.

Berberine Glucogold

Healthy Directions has been a leader for over 25 years in providing doctor-formulated nutritional supplements. Dr. Whitaker, the pioneer of the company, researched natural therapies and their potential for both maintaining and restoring health as an alternative to prescription drugs and invasive procedures, which led to the creation of his supplement line.

His supplements are primarily tailored to support healthy blood sugar levels and he has used his own products to treat patients at the Whitaker Wellness Institute. Berberine Glucogold is Dr. Whitaker’s approach to improving blood sugar levels naturally and contains berberine HCl for superior absorption.

WellBetX Berberine

Natural Factors, the company behind WellBetX Berberine, sources all of its natural ingredients from Factors Farms which is certified-organic farmland in Candana, just south of the city of Armstrong, BC. The company has complete control over seed selection and harvesting which allows it to stand out against its competitors in terms of purity and overall quality.

Where To Buy Berberine

Berberine is widely available as an over-the-counter (OTC) supplement, so there is no need to look further than Amazon.

There are many brands selling berberine though, so it’s important to know how to find the best berberine product. To know if they are a reputable brand, look out for certificates of analysis, good reviews and clear sourcing.
