I have tried so many different brands of Berberine. In fact, at first, I fell for the ones that said "complex" and "proprietary blend," etc., and of course they were not that great. Once I grew more familiar with what I was looking for and needed for weight loss, I specifically began looking for actual BERBERINE and Berberine HCI. Ceylon Cinnamon and Chromium Picolinate (which I absolutely believe helps because I used to take it when younger and thin), are added benefits and something I now count as a plus / bonus with my Berberine supplements. Lastly, I needed something that wouldn't break the bank. These Ultra Berberine supplements fit the bill, and so far, I REALLY like them. For the past two months I think stress got to me and I ate an absurdly awful amount of 'bad' foods - I mean fried rice; ice cream sandwiches; rich pastas; butter, bacon, mayo-laden, and other bolillo-bread sandwiches; pizza; you name it. I ate so much of it that I was literally afraid to step on the scale ... until finally I did, while expecting at least a 20 lb. gain. Well, I actually LOST 1.2 lbs. LOL. I know, not a lot, BUT, I honestly had expected to have gone up by a lot - and was thrilled I didn't. I won't say it was these alone as I have also been taking Bragg's Vinegar pills and Omega 3's, but I am definitely buying more of these because I plan to NOT eat so much this month and expect them to work even better.
