What It Does

+
Formulated by Dr. Kevin Passero, Durable BERBERINE provides exceptionally safe and effective natural support for weight loss, blood sugar balance, metabolic health and cholesterol balance with a clinically proven 1,100 mg daily dose of standardized Berbevis® Berberine Phytosome™.*

Berberine is an extraordinarily powerful plant alkaloid clinically proven to effectively promote blood sugar balance—and weight loss. Berberine naturally increases levels of GLP-1, a key hormone that regulates fat-burning metabolism. It also activates an enzyme called AMPK to promote appetite control, reduced fat storage and blood sugar regulation, as well as balanced cholesterol.*

Widely considered the best berberine extract in the world, Berbevis® features a next-generation phytosome delivery system that gives it 10x better absorption than other forms.*

This cutting-edge formula also includes 300 mg of Greenselect®, an advanced, decaffeinated, phytosome-form green tea extract that has been proven to rev up metabolism and support weight loss of up to 30 pounds in 90 days. Greenselect® Green Tea Phytosome™ offers a 2-fold increase in absorption and a 20% greater antioxidant potential compared to standard extracts.*

Additionally, a therapeutic 200 mcg dose of premium-grade, highly absorbable Albion® chromium provides synergistic support for blood sugar balance. Research shows that chromium can help improve body composition while fighting cravings that can derail your weight loss efforts.*

No other supplement combines these effective ingredients into one convenient formula. Durable BERBERINE offers comprehensive support for healthy weight management, blood sugar regulation, metabolic health and cholesterol balance with just two capsules a day, without side effects.*

This synergistic combination of powerful, clinically validated ingredients:*
  • Can help you lose up to 30 pounds in 90 days
  • Reduces hard-to-lose visceral fat by 22% in 60 days
  • Reduces body mass index (BMI) by up to 13.9%
  • Can help shrink your waistline by up to 10.7%
  • Boosts GLP-1 levels to help increase fat-burning
  • Helps suppress appetite and promotes satiety
  • Reduces insulin resistance in as little as 30 days
  • Reduces fasting insulin levels by 42% in 60 days
  • Promotes metabolic health and blood sugar balance
  • Supports healthy cholesterol and triglyceride levels

General Product Info:
  • 60 vegetarian capsules (a 30 day supply)
  • Made in the USA in an FDA inspected, cGMP facility
  • Every batch is 3rd party tested for safety and purity
  • Packaged in premium, non-toxic amber glass bottles
  • One-year return policy with free return shipping

Why It Works

+
While berberine only recently began “trending,” Dr. Passero has been using it in his clinic for over two decades to help patients optimize their metabolic health for healthy, permanent weight loss, and natural blood sugar and cholesterol control. This 20+ years of experience went into formulating Durable BERBERINE, which features a potent 1,100 mg daily dose of a standardized, highly absorbable berberine extract called Berbevis®. Widely recognized as one of the best berberine extracts in the world, this phytosome-form extract utilizes an innovative delivery system to provide up to 10x better absorption than the berberine extracts found in most supplements.*

Berberine’s powerful weight loss promoting, metabolic boosting and blood sugar balancing effects are synergistically enhanced with 300 mg of clinically studied, caffeine-free Greenselect® green tea extract and a therapeutic 200 mcg dose of Albion® chromium for even greater benefits.*

What Is Berberine and How Does It Work?
Berberine is an extraordinarily powerful plant alkaloid found in some of nature’s most revered medicinal herbs, including barberry, goldenseal and Oregon grape root. Extensive scientific research shows that, among a slew of health benefits, berberine excels at promoting blood sugar balance—and weight loss—via its regulating effects on metabolism.*

Berberine activates an energy-stabilizing enzyme called AMPK, often referred to as the “metabolic master switch,” which helps maintain balanced blood sugar levels and overall metabolic health. In addition, berberine enhances insulin sensitivity, which means it helps cells respond more effectively to the hormone insulin that controls blood sugar levels. This can lead to better regulation of blood sugar, better appetite control and reduced fat storage.*

Recently, berberine has soared in popularity, due to its “side effect” of promoting healthy weight loss via its actions on blood sugar and metabolism.*

Berberine’s weight loss benefits may also be related to its ability to increase metabolic rate and influence the activity of genes and enzymes involved in fat metabolism. In addition, some studies suggest that berberine may impact hormones involved in appetite regulation, including ghrelin, a hormone that stimulates hunger, and leptin, a hormone that signals satiety.*

Berberine also helps reduce inflammation and promotes a healthy gut microbiome—two important factors in maintaining a healthy weight.*

Berberine has also been clinically validated to help lower total cholesterol, particularly the less favorable LDL type, and is effective in supporting healthy lipid levels. The patented berberine extract found in Durable BERBERINE was shown in a clinical trial to lower total cholesterol by 8% in just 60 days.*

For more targeted support for cholesterol balance, we recommend you try our Durable HEART formula, which can be taken together with Durable BERBERINE.*

Berbevis® Berberine Extract (1,100 mg)
Durable BERBERINE is made with Berbevis®, a patented, clinically studied, standardized phytosome-form berberine extract that is clinically proven to significantly reduce insulin resistance within just 30 days while reducing visceral fat by 22% on average within 60 days. Visceral fat, which surrounds your organs, is considered the most dangerous kind of fat.*

While typical berberine extracts are notoriously difficult for the body to absorb, Berbevis® solves this problem with a next-generation phytosome delivery system that offers 10x better absorption compared to other berberine supplements.*

In a landmark 60-day study Berbevis®:
  • Slashed fasting insulin levels by 42%*
  • Reduced HOMA score (a measure of insulin resistance) by 49%*
  • Decreased fasting blood sugar by 12%*
  • Reduced visceral fat by 22%*
Another study, a randomized, double-blind, placebo-controlled clinical trial produced similar results, with Berbevis® normalizing fasting blood sugar and moving subjects out of “danger zone” classification within 60 days. It also decreased visceral fat, reduced body fat mass, shrunk waistlines and lowered total cholesterol by 8%. No other berberine supplement has produced these impressive results.*

Greenselect® Green Tea Extract (300 mg)
Greenselect® is a patented, decaffeinated green tea extract shown in clinical trials to support weight loss of up to 30 pounds in 90 days when combined with a reduced calorie diet.*

Green tea polyphenols, particularly catechins such as epigallocatechin gallate (EGCG), have been extensively studied for their health benefits, including their role in supporting weight loss. Greenselect® combines green tea polyphenols with phospholipids in a phytosome delivery system to improve their absorption and bioavailability. Greenselect® offers a 2-fold increase in absorption and a 20% increase in plasma antioxidant potential compared to standard green tea extract.*

Greenselect® provides safe and extremely effective natural support for weight loss by stimulating thermogenesis (the process by which the body generates heat and energy from metabolism of food) and fat oxidation (the process of breaking down fat into energy). It also helps regulate appetite and promotes feelings of satiety, helping to prevent overeating.*

In one study, Greenselect® helped a group of men and women lose an average of 13.23 pounds in 45 days, and an average of 30.86 pounds in 90 days. This remarkable weight loss was accompanied with a 12% reduction in body mass index (BMI) after 90 days.*

Another clinical trial showed a 13.9% reduction in BMI, a 10.7% reduction in waistline for men, a 9.1% reduction in waistline for women and 7.1% reduction in fasting glucose all around.*

Albion® Chromium (200 mcg)
Durable BERBERINE features top-of-the-line Albion® chromium. This patented, chelated (amino acid-bound) form of chromium offers superior absorption, blood sugar balancing benefits and fat loss support.*

Chromium is an essential trace mineral that plays a crucial role in blood sugar metabolism, the body's ability to process and utilize sugar from the bloodstream for energy. It helps maintain blood sugar balance, which is a critical factor in reducing fat storage. Studies have shown that chromium can help increase lean body mass while decreasing body fat percentage.*

Chromium can also help fight cravings that can derail your weight loss plan. Some research suggests that chromium supplementation helps reduce cravings for carbohydrates and sweets by influencing neurotransmitters involved in appetite regulation.*

Timing of Results
Like most nutritional supplements, Durable BERBERINE will take time and consistent use in order to achieve maximum effectiveness. While individual results may vary, the clinical studies show the best results often begin around 60 days, with results that keep improving over time. Dr. Passero recommends taking Durable BERBERINE for at least 90 days before evaluating your progress so you can make a proper assessment.

Side Effects & Interactions

Long Term Use & When To Stop
Durable BERBERINE is safe to take on an ongoing basis. However, it is possible to switch to a maintenance dose of 1 capsule per day or to stop completely. This depends on various factors including your initial weight loss and/or blood sugar goals, genetics, diet and exercise routine.

For Those with Low Blood Sugar
If you plan to take Durable BERBERINE for weight loss support but already have normal or low blood sugar, you do not have to be concerned about this product lowering it further. The ingredients work specifically to promote blood sugar balance, so it will only have a blood sugar lowering effect if your levels are elevated.

Durable supplements: Put them to the test!

I’ve been taking supplements consistently for over 35 years. I’ve tried everything under the sun and I’ve developed an attuned system. Durable products have been VERY noticeable in terms of pain relief, energy, blood lab reductions, and overall feeling of vitality. My household uses 6 of their products and I intend to add another couple more in the coming months. I love that I just create a subscription and I don’t have to manage it myself….I get what I want and what I need just shows up and my job remains to just take them! I’m quite happy with my experience so far with these supplements. Well researched, superior forms, and easy to order and switch up my subscriptions anytime. In a world that seems to be increasingly toxic, we NEED to protect and fortify our bodies with Organic foods, superior supplements, sunshine, and exercise. I’m sold!
