Berberine Supplement

The numbers for my blood glucose, cholesterol and triglycerides have been very good since taking this product. I intend to keep on using it.

no help at all :(

I ordered a 6 month supply and after 4 months of taking Berberine I had no change in blood sugar level, A1C or any other improvements.

Berberine

I have used Berberine in the past. It helps control my blood sugar. That's why I reordered berberine.

BAD

Very bad! Open the capsules and look at what's in it! Maybe 10% is Berberine? and the rest??? UGH! I would have returned it but hubby through the receipt away. Buyer Beware!
