Panax Ginseng and Blood Sugar: What the Trials Show and What the Label Holds
Panax ginseng and blood sugar have been tested together in many small trials. A pooled review of 16 trials found fasting glucose about 5.6 mg/dL lower on average and no clear change in A1C. In Glyco Defender, ginseng is the 12th blend line, so one dropperful can hold at most 1.3 mg.

Does Panax ginseng lower blood sugar?
A little, in some trials, and not reliably. One review pooled 16 randomized trials with 770 people and found fasting glucose fell by about 5.6 mg/dL on average (Shishtar et al., PLoS One 2014).
The results varied a lot from study to study, and fasting insulin and A1C showed no clear overall change. The National Center for Complementary and Integrative Health calls the research on blood sugar control inconclusive and conflicting (NCCIH, Asian Ginseng).
How much ginseng is in Glyco Defender?
Not much. The label lists ginseng (Panax ginseng) root extract in 12th place of 21 blend lines, so one dropperful can hold at most 1.3 mg of it.
That ceiling comes from simple math. The whole blend weighs 15.47 mg, and a line in 12th place cannot outweigh the eleven lines above it. An even split gives about 0.74 mg. The exact amount is not printed, which US rules allow (21 CFR 101.36 (eCFR)).
| Measure | Amount |
|---|---|
| Trial doses | About 100 mg to 20 g a day (Shishtar et al., PLoS One 2014) |
| Label place | 12th of 21 blend lines |
| Most per dropperful | 1.3 mg |
| Even split | About 0.74 mg |
| Lowest trial dose vs label ceiling | Roughly 75 times more in the trials |
Is Panax ginseng safe with diabetes medicine?
It can be a concern. Ginseng might lower blood sugar, so people with diabetes should talk to a provider first, and it can affect blood clotting and interact with some medicines (NCCIH, Asian Ginseng).
Never stop or change a diabetes medicine because of a supplement. If insulin or a sulfonylurea is part of your plan, ask your doctor before adding anything that might lower glucose.
More cautions are on the side effects page.

See packsIs ginseng a reason to buy Glyco Defender?
No. The ginseng research is mixed, and the label dose is a sliver of what the trials used. Judge the drops on the whole label, not on one famous root.

FAQ01
Questions about ginseng and blood sugar
Is Panax ginseng the same as Siberian ginseng?
No. Panax ginseng is Asian ginseng. Eleuthero, sometimes called Siberian ginseng, is a different plant. Glyco Defender lists both, in 12th and 5th place, and neither amount is printed.
Does ginseng change A1C?
Not clearly. The pooled review of 16 trials found no significant overall effect on A1C or fasting insulin, though fasting glucose fell slightly (Shishtar et al., PLoS One 2014). Results varied widely between studies.
Can ginseng cause trouble sleeping?
Yes. Insomnia is the most common side effect of Asian ginseng (NCCIH, Asian Ginseng). Glyco Defender also lists guarana, a caffeine source, so a fixed morning time suits the drops better than evening.
Does the label say how much ginseng is in a dropperful?
No. Only the 15.47 mg blend total is printed. Because ginseng is listed 12th, the most it can hold is 15.47 divided by 12, or about 1.3 mg.
