Since I buy other supplements from this brand, I at least think I can trust the quality of the ingredient. But the quality control at bottling could use some work. When I opened the bottle, berberine powder was everywhere. I emptied it out onto a plate and found one defective capsule spilling its contents, so I got rid of that one. For the rest, I tried my best to clean the powder off with a paper towel, but even with that effort, every capsule tastes very bitter. Read more

I an not really sure how to review Supplements and Vitamins. so here is my disclaimer: This is not medical advice. Do your own research and (or) check with your doctor first. I did my own research First I did a web search to see what exactly Berberine is, what it was suppose to help with, what side effects were possible and recommended dosages. I looked to see if there were any medical studies done and what they found out. I also checked web sites that rated products and manufactures, And read some of the reviews from people who had tried or were using Berberine. Based on what I found I decided to give it a try. I decided to order the Berberine Supplement that is manufactured by Double Wood Supplements mainly because it was a low dose and they company had some good reviews. I got my order quickly. The Package looked good. and the bottle was sealed. I do have 2 tiny issues one is that there is loose yellow powder in the bottle. that gets on my hands. I am guessing that some of powder leaked out from capsules The second thing is that occasionally I get a very bitter taste after taking it. I just have to drink more water when that happens. When it is time for me to get more Berberine I plan to order it from Double Wood Supplements Read more

For some reason this Berberine has a lot of yellow Berberine powder outside of the capsules which does make the taste a little bitter, however, because the other brands of Berberine are more than three times as expensive, I still think it is a great deal. I have to take 4 capsules a day prescribed by my doctor, and after 6 months I am feeling great. Read more
