Blood Sugar Supplements List: What Each Common Ingredient Has Going For It
A blood sugar supplements list names the ingredients sold for glucose support, such as chromium, gymnema, ginseng, carnitine and cinnamon. The evidence is weak or mixed for all of them. Chromium trials used 200 to 1,000 mcg a day, while Glyco Defender holds 7 mcg. We grade each ingredient in plain words below.

What belongs on a blood sugar supplements list?
A blood sugar supplements list holds the herbs, minerals and amino acids that makers pair with glucose claims. Most come with small studies and mixed results.
The NCCIH says only weak evidence exists for a few of them, such as chromium, cinnamon and berberine (NCCIH, Diabetes and Dietary Supplements). The grades below are ours, in plain words. They are not an official rating.
How strong is the evidence for each ingredient?
Weak to mixed for every item. None earns a strong grade.
| Ingredient | Dose in studies | Our grade |
|---|---|---|
| Chromium | 200-1,000 mcg a day | Mixed (NIH ODS, Chromium) |
| Gymnema | 200-400 mg extract | Small effect (Drugs.com, Gymnema monograph) |
| Panax ginseng | 100 mg to 20 g a day | Small, no A1C change (Shishtar et al., PLoS One 2014) |
| L-carnitine | 2-3 g a day | Limited (NIH ODS, Carnitine) |
| Cinnamon, berberine | Varies | Weak |
| Maca | Few small trials | No blood sugar proof (MSKCC, Maca) |
Which blood sugar supplements list items are in Glyco Defender?
Chromium, gymnema, ginseng, carnitine and maca are all there, plus 17 more lines. Cinnamon and berberine are not.

FAQ01
Glyco Defender questions people ask
Which ingredient on a blood sugar supplements list has the most evidence?
Chromium has the most study, at 200 to 1,000 mcg a day, yet results are mixed. A 2019 review found slight drops in people with diabetes of unclear clinical value.
Is cinnamon better than chromium for blood sugar?
Neither is proven. The NCCIH lists both among the few supplements with weak evidence. Ask your doctor before using either, since both may interact with diabetes medicines. Glyco Defender contains chromium but no cinnamon.
Do all ingredients on the list interact with medicine?
Not all, but several do. Chromium may add to diabetes drugs and ginseng may affect clotting. Show your pharmacist the full label before starting.
