I have been pre diabetic for about 4 years and my fasting glucose was creeping up every single time I went in for blood work. My doctor was about to put me on metformin and I asked if I could try a few lifestyle things first. I cleaned up my diet, started walking after meals, and added this. My next A1C dropped from 6.1 to 5.6. My doctor was genuinely surprised and asked me what I was doing differently. I will say I think the walking after meals matters a lot too but this absolutely played a role. I take it before my two largest meals. The other thing I notice is my afternoon cravings for sugar are way down. I used to need something sweet around 3pm every day and that compulsion is just gone. I'm staying on it. My husband started taking it too after seeing my labs.

I have PCOS and have been told my whole adult life that my insulin resistance was making it impossible to manage my weight. After 3 months on this my cycles are more regular and I have actually started losing weight without changing much else. I'm not saying this is a magic pill but for me it has done more than anything else I have tried.

My doctor was actually the one who suggested I try berberine after my last A1C came back at 6.0. I picked this brand because of the dose and the reviews. Three months in my A1C is 5.4 and my cholesterol numbers also improved which was a nice bonus. My doctor is now recommending it to other patients.

My fasting glucose has gone from 110 to 92 over about 8 weeks. I haven't changed anything else dramatically. I take it with my biggest meal of the day.

I am a registered dietitian and I generally don't recommend supplements but berberine is one of the few that actually has decent research behind it for blood sugar management. I bought this for myself because my fasting glucose was in the high prediabetic range and I wanted to try it before resorting to medication. After about 10 weeks my numbers are back in the normal range. I'm not saying it replaces a good diet but it has been a useful tool alongside the changes I was already making. I have started cautiously suggesting it to clients who want to try a supplement alongside their nutrition plan, with the standard reminder to check with their physician first.

I took this for 12 weeks consistently and my fasting glucose only dropped about 4 points. My doctor said that's within normal day to day variance so we can't really attribute it to anything. I have type 2 diabetes that has been progressing for over a decade so I may just be past the point where a supplement is going to do much. Not a knock on the product, just my situation.

I picked this up after reading some studies comparing berberine to metformin. My pre meal numbers used to spike to the high 160s and now they barely hit 130. Took about 6 weeks to really see the change but it has stayed consistent for 4 months now.

Works but caused some GI discomfort the first 2 weeks. Once my body adjusted it was fine. Glucose numbers are definitely better. Just be ready for an adjustment period.

Type 2 diabetic for 8 years. Been on metformin the whole time. My doctor was open to me adding berberine and my last A1C was the lowest it has been since diagnosis. I am not stopping metformin without my doctor saying so but this has definitely helped.

I had gestational diabetes and have been worried about developing type 2 for years. My OB cleared me to try this and my fasting glucose has stayed below 90 consistently now. I am much less anxious about my future health.

Helps with my glucose numbers but it is on the pricier side compared to other brands. I keep buying it because the formulation seems better than the cheap ones I have tried.

Questions?
We're here to help.

Digestion shifts first, often within 2 weeks. Blood sugar effects show up at 4 to 8 weeks. Cholesterol and triglyceride changes compound over 8 to 12 weeks. The clearest read on lab results comes around the 90-day mark.

The most common side effect is mild GI discomfort in the first week. Always take with food. Splitting the dose between lunch and dinner reduces this for most people. Symptoms usually settle within 7 to 10 days.

With your two largest meals. Splitting the dose across the day works better than taking both capsules at once. One with lunch, one with dinner is the most studied protocol.

Berberine and supporting alkaloids exist in different concentrations across the plant. Bark is the most common source on the market. Root contains additional compounds that round out the profile. Whole-plant sourcing delivers the full spectrum, not just isolated berberine.

Talk to your healthcare provider before combining berberine with diabetes, blood pressure, or cholesterol medications. Berberine can amplify the effects of these prescriptions and may require dose adjustment. Do not stop a prescription without your doctor's input.
