Berberine is a well-researched plant compound in metabolic wellness. It is an alkaloid extracted from Berberis aristata with centuries of use in traditional Chinese and Ayurvedic medicine, and a growing body of modern clinical evidence supporting its role in glucose metabolism, carbohydrate handling, cardiovascular health, and AMPK activation. AMPK, adenosine monophosphate-activated protein kinase, is often described as the body's "metabolic master switch," a cellular energy sensor involved in how the body processes glucose and manages energy balance. Berberine is one of the few plant-derived compounds studied for its ability to activate this pathway in cellular and animal research.*
Double Wood's formula delivers 500mg of berberine HCl per capsule, verified by HPLC (high-performance liquid chromatography) on every batch, the same analytical method used in published clinical research. Independent testing has found that potency varies across the berberine category more than many buyers expect. Our most recent COA confirmed not less than 500mg berberine HCl per capsule, tested by a PJLA-accredited ISO/IEC 17025:2017 laboratory. The 500mg capsule size is intentional. Clinical research typically uses 900–1,500mg daily in divided doses with meals, and a single 500mg capsule gives you flexibility to find the right serving for your body rather than locking you into a fixed dose.
For a more complete metabolic wellness regimen, Berberine pairs naturally with Citrus Bergamot, which supports healthy lipid metabolism and cardiovascular wellness, addressing both glucose and lipid pillars of metabolic health in a single daily routine.*
Powerful alone, stronger together. Berberine Supplement delivers targeted support on its own, but combining it with complementary ingredients can help create a more holistic and balanced approach to wellness.
Overall rating: 4.869919 / 5 from 123 reviews.
The Berberine Supplement is praised for its excellent pricing, high quality, and effectiveness in lowering A1C, cholesterol, and blood sugar. Customers also appreciated the noticeable reduction in post-meal brain fog and 'carb crash' symptoms. However, there are mixed opinions regarding the order experience.

"Works great. Especially, if you are on a budget."
"I wanted to share an honest review for anyone really looking into Berberine and trying to find something that actually works without upsetting your system. I’ve tried other Berberine supplements before, but many of them included green tea or caffeine, which completely irritated my stomach. That just didn’t work for me. Double Wood’s formula has been much more gentle, which was a huge relief. I currently take their Inositol and Berberine together, and I’ve noticed a real difference—especially with cravings. I’m on a GLP-1 and was still struggling with sweet cravings and nighttime hunger, but within about three days of taking this, those cravings noticeably decreased. I follow the recommended dose (one per day), and I’m planning to get updated labs soon to see how everything looks, especially since my weight has been slower to move even with GLP-1. Of course, diet and exercise still matter, but this supplement feels like it’s actually supporting those efforts instead of working against them. Overall, Double Wood has been one of the most reliable brands I’ve used. Their products are consistent, effective, and easy on my stomach—which is everything for me."
"A1C was 6. 8. Started Berberine on the advice of my doctor. After 3 months, A1C of 6. 3. Will definitely keep taking."
"Stomach"
"This one seems to do its job but many of the other ones seem to have lost strength or something. Colors have changed and effects are just not there anymore."
"I placed an order and twice it did not arrive,."
"This has been easy to take and gentle on my stomach. Will purchase again."
"I just started taking it. I won't be able to tell until my next labs. I'm taking to lower my A1c and lipids. This along with diet."
"Great for blood sugar. Nature’s way of cutting down on the liver producing sugar. 1 in AM. 1 in PM."
