Gymnema in Glyco Harmony: Amount, LiverTox Rating and Research
Glyco Harmony gymnema is printed as Gymnema Leaf Extract, name 8 of 22 in a 200 mg proprietary blend. Because names run by weight, it can weigh at most 25 mg per 1 mL serving. LiverTox rates gymnema D, a possible rare cause of liver injury, and says its use for diabetes has not been established.

On the label01
What is gymnema in Glyco Harmony?
Gymnema in Glyco Harmony is "Gymnema Leaf Extract", the eighth of 22 names in the 200 mg Proprietary Blend. It comes from the leaf of Gymnema sylvestre, a climbing plant.
The leaf has been used traditionally, including as a tea for type 2 diabetes (LiverTox, Gymnema). The label does not say how the extract was made or whether it is standardized to a set strength. It prints no amount for gymnema, only its place in the list.
| Name on the label | Gymnema Leaf Extract |
|---|---|
| What it is | Leaf extract of Gymnema sylvestre, a climbing plant |
| Per 1 mL serving | not printed; at most 25 mg |
| % Daily Value | Not established |
| Amount used in research | Human trials showed modest drops in fasting glucose, sometimes with rises in A1C; the label's ceiling is 25 mg |
| Strength of evidence | Weak: effectiveness for diabetes has not been established (LiverTox) |
| Marketed or traditional use | Leaf used traditionally, including as a tea for type 2 diabetes |
| Main caution | Possible rare liver injury (one case of jaundice on gymnema tea). Any herb that changes blood sugar can add to diabetes medicine. |
The arithmetic02
How much gymnema is in Glyco Harmony?
The label does not say. It lists gymnema eighth, so by the blend rule it weighs at most 200 ÷ 8 = 25 mg per 1 mL serving (eCFR, 21 CFR 101.36 (proprietary blends)). That is a ceiling, not an amount.
The rule requires the total blend weight and the order of names by weight. It does not require each amount. So gymnema may weigh far less than 25 mg, and nothing printed tells you how much less.
If one dropper is 1 mL, an assumption the label does not confirm, 2 droppers a day would raise the ceiling to 50 mg. The numbered spots below show where the blend total and the names sit on the panel.
| Printed name | Gymnema Leaf Extract |
|---|---|
| Place in the list | 8 of 22 |
| Most it can weigh per 1 mL | 25 mg (200 ÷ 8) |
| Amount printed | Not printed |
| Standardized strength | Not printed |

Liver safety03
What does LiverTox say about gymnema?
LiverTox, the NIH database on drug and supplement liver injury, gives gymnema a likelihood score of D: a possible rare cause of clinically apparent liver injury (LiverTox, Gymnema).
The entry describes one detailed case. A 60-year-old woman developed jaundice while drinking gymnema tea for type 2 diabetes. Her liver tests returned to normal in about six months after she stopped.
A score of D is a low-confidence signal. It does not say gymnema harms most people, and it does not say it is safe. It is a reason to know the warning signs.
- Watch for. Yellow skin or eyes, dark urine, unusual tiredness or pain under the right ribs.
- If they appear. Stop the drops and call your doctor.
- Tell your team. Mention every supplement, including this one.
Green tea extract, also in the blend, has its own liver reports. See the green tea profile.
The research04
Does gymnema lower blood sugar?
Small human trials showed modest drops in fasting glucose, sometimes with rises in A1C, and LiverTox says effectiveness for treating diabetes has not been established (LiverTox, Gymnema).
A 2007 systematic review was done because the evidence on gymnema as a diabetes treatment needed assessing (Leach 2007, Gymnema systematic review). We could read only its opening lines, so we quote no findings from it.
The NCCIH says evidence of benefit is weak for a few supplements and absent for most (NCCIH, Diabetes and Dietary Supplements). No study tested gymnema at a share of a 200 mg blend, and none tested Glyco Harmony.
Gymnema is not approved as a treatment for any condition. It is sold in the U.S. as a supplement.

Is gymnema safe with diabetes medicine?
Ask your doctor or pharmacist before you take it. Gymnema is studied for its effect on blood sugar, so it may add to insulin or diabetes pills, and low blood sugar is possible.
Low blood sugar can feel like shakiness, sweating, hunger or a fast heartbeat. Confusion, fainting or a seizure needs 911 (CDC, Low Blood Sugar (Hypoglycemia)). Low blood sugar is most often caused by diabetes medicine itself (Mayo Clinic, Hypoglycemia).
Keep taking prescribed medicine. Never change insulin or diabetes medicine because of a supplement.
Chromium, L-arginine and ginseng also have sources that say they may add to the effect of diabetes medicine. Together with gymnema, that is four names in one bottle to mention to your pharmacist. The label says pregnant or nursing mothers, children under 18 and anyone with a medical condition should consult a physician first.
A sales-page claim06
Is gymnema really a sugar destroyer?
No cited source supports that. The sales page calls gymnema a "sugar destroyer" and says it helps regenerate pancreatic cells, and it cites no study (Glyco Harmony sales page).
Sources we could verify say its effect on diabetes is not established. Treat the sales wording as marketing, and the label as the document that counts.

Gymnema in Glyco Harmony: your questions
What is the LiverTox score for gymnema?
LiverTox rates gymnema D, meaning a possible rare cause of clinically apparent liver injury. Its entry describes one detailed case of jaundice linked to gymnema tea. It is a weak signal, not a ban.
How much gymnema is in Glyco Harmony?
The label does not say. Gymnema is the eighth of 22 names in a 200 mg blend, so it can weigh at most 25 mg per 1 mL serving. The real amount may be much lower.
Is gymnema approved for diabetes?
No. LiverTox says gymnema is sold as a supplement in the U.S. and is not approved as a treatment for any condition. Effectiveness for diabetes has not been established.
Can gymnema cause liver problems?
Rarely, according to LiverTox. Watch for yellow skin or eyes, dark urine or pain under the right ribs. If they appear, stop the drops and call your doctor.
Does gymnema affect blood sugar tests?
Trials reported modest drops in fasting glucose and sometimes rises in A1C. If you track your numbers, tell your doctor you take it, and do not adjust any medicine on your own.
Is gymnema the same as gymnemic acid?
No source we verified covers gymnemic acid, and the label does not say whether the extract is standardized. All it prints is Gymnema Leaf Extract, in eighth place.
Is gymnema safe during pregnancy?
We found no verified source for it. The label tells pregnant or nursing mothers to consult a physician before using any dietary supplement, so ask yours.
