Nano Berberine Powder 8 oz (227 Servings), Berberis aristata Extract, Supports Healthy Blood Sugar Levels for Metabolic Health, Excipient-Free, Non-GMO, Vegan, Gluten-Free

I have purchased this supplement a few times. This time when I opened it the color is not the color the powder usually is. Tried to return for a new bottle and there is no option to return at all. On the original ad for the product it does not say it is not returnable. So now I am out of money and don’t have a quality product that I am willing to take. Not good customer service. Guess I will be going back to my old brand.

I have taken this product for a week, and each time I got very fatigue, sleepy and not able to function. I was told about this product as a good thing for a person with cancer, but it made me really weak I didn't know it drops your blood sugar level not what I wanted this to do. I will have to trash this because I almost passed out in the grocery store very difficult time getting home.
