Bests & Worsts Reviews from Amazon

I'll preface this review with the fact that I have been a whole food, plant based eater for many years. My diet consists of whole foods (fruits, vegetables, legumes, nuts and seeds). I get over 50 grams of whole food fiber in my diet every single day. Needless to say, I never have bowel issues. The constipation started about 2 days after beginning the supplement. I was taking about 1/4 of the recommended dosage just to be cautious so this is certainly not a dosage issue. I'm 60 years old and have never experienced anything like this in my life. I'm talking over a week without a bowel movement!!!! I realize that not everyone will experience this side effect but if you have bowel issues shortly after starting berberine, you might be one of the unlucky ones.
