Blood Sugar Supplements Berberine: Is It in Glyco Defender?
No, Glyco Defender does not list berberine. Its label shows 7 mcg of chromium and a 15.47 mg proprietary blend of 21 lines, and berberine is not one of them. NCCIH calls the evidence that berberine helps blood sugar weak, based on small, inconsistent studies.

Does Glyco Defender contain berberine?
No. Berberine appears nowhere on the Glyco Defender label, in the blend or in the other ingredients.
The label lists chromium picolinate, then 21 blend lines from maca root extract to L-carnitine HCl. The ingredients page prints all 22 lines, so you can check for yourself.
Search results sometimes mix brands. If a page says Glyco Defender contains berberine, it disagrees with the bottle.
What does the evidence say about berberine and blood sugar?
The evidence is thin. NCCIH says weak evidence from small, inconsistent studies suggests chromium, cinnamon and berberine may help blood sugar control (NCCIH, Diabetes and Dietary Supplements).
That is a long way from proof. NCCIH adds that no herbal supplement has reliable evidence for controlling diabetes, and that unproven products must never replace medical treatment.
The American Diabetes Association likewise finds no supplement proven to lower glucose (ADA, Vitamins & Supplements).
How is a berberine product different from this label?

FAQ01
Questions about berberine and this label
Which ingredients in Glyco Defender are studied for blood sugar?
Chromium, gymnema and ginseng are the best known, but studies used much larger doses than the label allows. For example, gymnema studies used 200 to 400 mg of extract; the label holds at most 1.9 mg (Drugs.com, Gymnema monograph).
Is berberine safe with diabetes medicine?
Not without advice. The ADA warns that supplements can cause low blood glucose when combined with diabetes drugs (ADA, Vitamins & Supplements). Ask your doctor or pharmacist before adding any new blood sugar supplement.
Where can I read the full Glyco Defender label?
The supplement facts page shows the panel with a word-for-word transcript, including the footnotes on extract ratios and the other ingredients.
