Buy these

These have worked for me. Curbs hunger and don’t crave sweets. No side effects so far just sometimes a burp that’s not so great

It really works!!

I bought Clinical Grade Berberine 500mg about 2-3 weeks ago. I was very skeptical but I ordered it anyway just with the hope that it might help lower my blood sugar numbers. Nothing had seemed to work before, but I was willing to give it a try. Well, it truly has helped bring my numbers down from 190-230 down to 130-160 consistently. I will be sure to reorder Berberine again. Thanks for a wonderful product.

Works even better than my prescription pills

I've been using this product for a few years now and not only has it lowerd my excessive blood suger levels by a large margine but also my tolal cholesterol levels too. Also no bad side effects only good ones. Sometimes I've tried other pills for awhile but always come back to this one.

My Review

I am now beginning my 2nd month on the Berberine. I actually just "upgraded" to the Berberine Gold.....This is the FIRST TIME in several years, even with losing all of my weight and eating extremely healthy, that my blood sugar has come down to normal levels!! At my last appointment with my physician approximately 3 months ago, they even wanted to start me on insulin shots!! I am sooo thrilled about this product! I highly recommend! Thank you!

Good brand of Berberine

I have taken this Berberine for a few years on and off and it has definitely helped my lipid levels. I do recommend this product.

I think it REALLY works!

I am only taking 1-2 a day instead of the 3, one before each meal. This pill makes me very regular and i can feel myself completely emptying. I am a nurse and i know my self when it comes to irregularities...i am happy with what it's doing to my body. I have HA1C in july so i'm excited about the result. Keeping my fingers crossed.

did not work as good

The price was really great as it was the promotional deal. The berberine did not work as good as maintaining my blood sugar low, especially the morning one, as other brands I tried... I was disappointed, since I had heard of Dr. Whitaker... but I also understand that each different brand may work differently with each individual. I did try switching back and forth and this one is not as potent. Just me and my try out.

Didnt work for us.

Didnt lower sugars. According to the Libre, the sugars went up during the period of time the supplement was taken. We can see the data patters. Data is good to have to monitor the effectiveness of this product
