Diabetes Offer: Berberine Supplement | Supplements - health

Complete evidence review for diabetes management

A

Evidence Rating

Strong Evidence

Summary

Berberine is the single most studied natural compound for blood glucose management, with a level of evidence that approaches some prescription medications. Meta-analysis of 28 randomized controlled trials shows consistent A1C reduction of 0.5-0.9% and improvements in fasting and post-meal glucose. However, it has significant drug interactions, particularly with metformin, and should only be used under medical supervision.

5 Specific Ways Berberine Can Stabilize Your Blood Sugar

Berberine has been prized for centuries for its healing properties. Now this potent herb naturally balances blood sugar levels by helping your body:

Decrease insulin resistance, making the blood sugar-lowering hormone ‘insulin’ more effective

Berberine may activate the ‘metabolic master switch’: An energy-stabilizing enzyme found inside cells, AMPK (adenosine monophosphate kinase), is known as a ‘metabolic master switch’ due to its positive influence on metabolism.[*] It’s believed that this helps improve insulin sensitivity at the cellular level.

Decrease sugar production in the liver

Berberine helps slow the sugar factory: According to studies, berberine may stimulate glycolysis, the metabolic pathway by which sugar is broken down and converted to energy, and may inhibit gluconeogenesis, the creation of glucose.[*] In effect, these activities decrease insulin sensitivity and help to balance blood sugar levels.

Slow the breakdown of carbohydrates

Berberine supports the liver: Plant compounds are thought to help improve insulin sensitivity in the liver by reducing its production of glucose. Additionally, berberine is thought to boost thermogenesis. These activities help suppress the liver’s tendency to make new glucose when liver cells become insulin-resistant.

Increases the number of beneficial gut bacteria. ¹

Several studies have shown that berberine may modulate the gut microbiota through enriching short-chain fatty acid (SCFA)-producing bacteria and reducing microbial diversity. This, in turn, inhibits dietary polysaccharide degradation and decreases caloric intake in the gut, which may improve energy metabolism and intestinal health, as well as exert anti-inflammatory and immune regulatory effects.

Removes deep body fat that accumulates around the belly and organs

There’s a strong correlation between blood sugar and weight loss. Research on berberine for weight loss and fat-burning activity is limited but promising. In one 12-week study, subjects lost about 2.3% body weight — or 5 pounds — and lowered BMI and body fat percentage by 3.6% with a dosage of 3,500 mg per day.[*] Another 3-month study revealed a drop in BMI, from 31.5 to 27.4, in obese individuals, as well as a reduction in waist circumference.

Why We Added Berberine To
Our Store - The Story

As a caregiver myself to a family member with symptoms of Type II, we tried a lot of the doctor's mainstream advice (exercising, dieting) with very little success. It was through a consultation with a Traditional Chinese Medicine (TCM) practitioner that we learn about Berberine. The results we obtained through consuming Berberine were remarkable.

We started offering the product to other people who struggled to maintain healthy blood sugar levels. During a two year period we have received some really notable testimonials. Read some of them below.

Berberine Success Stories*

“Her daily sugar is lower than it has ever been.”

I have been taking Berberine to help lower my A1-C. I'm not that high, 5.6 but since Type II runs in my family, I want to keep it as low as I can. Since taking the Berberine, my A1-C has gone down to 5.5. I have ordered some for my mother, who has an 8.4 A1-C, and she has noticed her daily sugar is lower than it has ever been. I am anxious to see what her results will be when she goes back for blood work. - Cheryl L Young

“Works better”

Thank you, I love this product! I have not had to take metformin for a year because it works better!! - Brooklyn Perry

“Blood sugar came down”

After one cap last night, after a meal, my blood sugar came down. - Ray Webb

“Lowered my blood sugar levels without any ill effects.”

I suffer from PCOS, and Metformin made me ill. Berberine has lowered my blood sugar levels without any ill effects. - Elizabeth Mitchell

“This product is a fantastic product.”

I got it for my uncle; his sugar dropped from between 200 and 400 to 80 just the next morning, and it has been running between 70 and 100 for about two months. His blood Pressure is better, and his energy level has gone up. He is back to caring for himself daily and walking without support. Thank you very much for this product. - Strong

“Totally happy with product.”

I bought this product because i had read that it removes deep body fat; this is the fat that accumulates around your belly and many organs, which was confirmed on mayo clinic website. It also claims that it lowers blood sugar and cholesterol and boosts metabolism. All I know is that since I have started taking my weight has gradually decreased when all i am doing is trying to maintain. haven't had sugar and cholesterol checked, but will definitely continue to use it. - J.S Wise

To use Berberine to heal without side effects, the Berberine needs to pass 2 TESTS:

Test #1

Now, it's a known fact that for Berberine to have its best effects, the recommended daily dosage is around 1500mg.

The problem is Berberine is very potent stuff, and consuming 1500mg in a single dosage can cause stomach discomfort, cramp,s and even have you running to the bathroom every 15 minutes. 

Many studies have shown that you should take Berberine 500mg, three times daily, to reach the correct recommended dosage. Using separate doses improves absorption, but more importantly, it helps you avoid side effects like stomach cramps and nausea that arise from a concentrated 1500mg dose.

So it had to be in a capsule form: at 500mg per dose.

So we had to use Berberine sourced organically from the tree bark of Phellodendron Amurense, sterilize them after harvesting, and extract the Berberine into a 500mg dose, capsule form.

Test #2

One extra ingredient was added to amplify Berberine’s results. 

A little-known flowering herb, Milk Thistle, which belongs to the daisy and ragweed family. It’s often called the Holy Thistle because it has a long history of treating liver problems, lowering cholesterol, and lowering inflammation.

But the real benefit is in the fact that Milk Thistle’s main active ingredient is Silymarin, and once combined with Berberine, it was shown in one study to increase the bioavailability of berberine in the intestines and to raise its concentration in the blood for longer periods of time.
