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.*

The Doctor Behind The Formula

Dr. Kevin Passero Answers Your Questions

Why is Durable BERBERINE superior to other berberine formulas?

+

Durable BERBERINE is made with a patented, highly absorbable form of berberine called Berbevis® that offers 10x better absorption and bioavailability compared to typical berberine supplements thanks to its next-generation phytosome delivery system. Berbevis® is also standardized, which ensures that Durable BERBERINE provides consistent, clinically validated levels of the active compounds needed to effectively support blood sugar balance, weight management and overall metabolic health.*

This advanced formula also provides standardized, caffeine-free Greenselect® green tea extract, which has been clinically proven to support dramatic weight loss results in combination with a reduced calorie diet. It also includes Albion® chromium for additional blood sugar balancing benefits.*

And, like all Durable products, Durable BERBERINE is manufactured in an FDA inspected, pharmaceutical-grade, cGMP certified facility and independently tested for quality, potency and purity, so you can be assured you are getting a safe and effective supplement.*


When is the best time to take Durable BERBERINE?

+

I recommend taking one capsule twice daily before lunch and before dinner, or as directed by your healthcare practitioner. If for some reason you skip lunch and/or dinner, take one capsule with your two largest meals of the day.*

When taken before a meal, berberine helps to control appetite and regulate the breakdown and absorption of sugar and carbohydrates. These benefits help reduce caloric intake and control insulin levels and other hormones that regulate fat cells.*


Can I take less or more than the recommended dose?

+

For additional benefits, the dose can be increased to one capsule three times per day to provide extra support for weight loss, blood sugar balance and metabolism. Take one capsule before breakfast, lunch and dinner.*

If you experience any digestive upset or are someone with a sensitive system, you can take one capsule daily for the first 14 days and then increase up to the full dose of one capsule twice daily.*


How long does Durable BERBERINE take to work?

+

Like most nutritional supplements, it takes some time for the ingredients in Durable BERBERINE to build up in your body to deliver beneficial results. While individual studies vary, the most common benchmark used in the studies on berberine was 60-90 days.*

As with all natural products, each individual can have different results. That's why I recommend taking Durable BERBERINE for at least 120 days. This is also the reason why we offer an amazing one-year any reason guarantee.


What if it doesn't work for me?

+

Don’t worry, all of our premium health formulas are backed by our any reason, 100% refund guarantee for one full year after purchase. We even pay for return shipping. I want Durable BERBERINE to work for you, and if it doesn’t, I want you to have your money back so you can try something else!


Can I take Durable BERBERINE for weight loss support if I already have normal or low blood sugar?

+

Yes. If your blood sugar is normal (or low), you do not have to be concerned about Durable BERBERINE lowering it further. The ingredients work specifically to promote blood sugar balance, so it will only have a blood sugar lowering effect if your blood sugar levels are elevated.*


Can I take Durable BERBERINE in conjunction with blood sugar medication?

+

If you are taking any medications or have a medical condition, please consult with your healthcare provider before taking Durable BERBERINE.


What is the Nuflow Complex that is listed in your Other Ingredients?

+

Nuflow is a natural filler and flowing agent made from the outer hulls of rice. Flowing agents are used in the production of all encapsulated or tableted supplements to help prevent the ingredients from clumping as they flow through the encapsulating machinery. Most companies use synthetic flowing agents like silicon dioxide, magnesium stearate, talc or steric acid, which can potentially inhibit the absorption of the active ingredients or may be potentially harmful.*

Big thumbs up

I started taking this Brands Berberine about 1 month ago. My morning fast blood glucose levels were always 131-141- a little high. Since taking berberine, my levels are now 94-112. A major difference!

Happy!!

Had my routine blood work in April and my sugar levels (glucose) were sightly elevated. Been searching for something to help lower my levels, came across these supplements and thought I have nothing to lose…. So I ordered the Durable BERBERINE. Been taking 1 pill 2x a day faithfully for about 7 weeks. Having rotator cuff surgery so I needed blood work for clearance, and received my results today and my glucose levels went down 14 points, very happy and surprised. Honestly I was skeptical taking these supplements because everything now promises results… definitely worth the purchase!!! Money well spent…

Clean supplementation

I like that there aren’t a bunch of sketchy ingredients added to these supplements. Seems like you’re getting the supplement you’re after and not other unwanted ingredients. I like this.

Seems to be helping!

My wife has been using Durable Berberine for a few months now and her blood sugar numbers have seen steady improvement. She's very close to having normal blood sugar readings for the first time in several years, so we're very satisfied with the product.

Lowered my LDL cholesterol

My cholesterol has been elevated since menopause. It is genetic. Both parents and my sister have high cholesterol. I stumbled onto the Durable site by searching for Bergamot. My functional medicine dr said this can lower my cholesterol along with Berberine, diet and exercise. I already eat well and exercise so needed some help. In 6 months, my LDL cholesterol dropped 35 points. I am hoping that it will drop further at 1 year. I am very happy with the product and may add the red yeast a few times a week to try to normalize my cholesterol.
