I bought these supplements for my mother who is taking metformin for type 2 diabetes. I was a bit reluctant although i had researched quite a bit and they had shown scientific proof for the control of blood sugar. Now 3 weeks on i can confirm that these are working very well and my mother has completely stopped taking metformin and her reading are always in the specified ranges.
I have now been using this for several weeks with my GP's knowledge and approval. I have found no side effects and generally feel better and stronger physically since taking Berberine. I would recommend this as a good alternative for those who cannot get on with mainstream products
