Mostly not. Chromium gives 1.4 mcg a day, against 200 to 1,000 mcg in trials (NIH ODS: Chromium fact sheet). Gymnema can reach at most 50 mg a day, while studies used about 300 to 500 mg (LiverTox: Gymnema).

Cautions

Which GlucoZen ingredients need care?

Gymnema and Asian ginseng may lower blood sugar; ask your doctor if you take diabetes medicine (LiverTox: Gymnema) (NCCIH: Asian ginseng).
Licorice (glycyrrhizin) has caused severe effects in people with high blood pressure, heart or kidney disease (NCCIH: Licorice root).
L-tryptophan was recalled in 1989-1990 after an outbreak of a rare illness called EMS (CDC MMWR: L-tryptophan and EMS).
Guarana and green tea add caffeine in an unstated amount.

Details are on the medicines page.

Evidence

Is there research on GlucoZen's ingredients?

There is research on single ingredients, but no published trial of GlucoZen itself. The American Diabetes Association finds too little evidence to back herbal supplements for blood sugar (ADA Standards of Care 2026, Sec. 5). NCCIH warns never to swap diabetes care for an unproven product (NCCIH: Diabetes and dietary supplements).

In fairness, every ingredient is named, and the herbs are familiar food plants.

Not on the label

Is berberine or cinnamon in GlucoZen?

Not on the bottle. The brand info page names berberine, cinnamon, turmeric and probiotics, but the Supplement Facts do not. Read our label versus marketing guide and trust the label on your bottle.

FAQ

GlucoZen ingredients FAQ

What is the main ingredient in GlucoZen?

Maca root extract is listed first in the 200 mg blend, so it weighs the most of the 22. Chromium is the only ingredient with a printed amount, 0.7 mcg per 1 mL, which is 2% of the Daily Value.

Does GlucoZen have gymnema?

Yes. Gymnema leaf extract is eighth of 22 in the blend, so it weighs at most 25 mg per 1 mL, or 50 mg a day. Human studies used about 300 to 500 mg daily (LiverTox: Gymnema).

Is there licorice in GlucoZen?

Yes, as monoammonium glycyrrhizinate, 18th in the blend. NCCIH says glycyrrhizin can cause irregular heartbeat and, even in small amounts, severe effects in people with high blood pressure or heart or kidney disease (NCCIH: Licorice root).

Does GlucoZen contain L-tryptophan?

Yes, 21st of 22, so it weighs at most about 10 mg per 1 mL. CDC records link 1989-1990 L-tryptophan supplements to 1,536 cases of a rare illness and 27 deaths, which led to a recall (CDC MMWR: L-tryptophan and EMS).

Are GlucoZen ingredients natural?

Most are plant extracts and amino acids. The liquid also holds deionized water, organic citrus extract, natural flavors, stevia and xylitol. No third-party certifier is named on the label.

Do GlucoZen ingredients work for diabetes?

No trial of GlucoZen is published, and it does not treat diabetes. The ADA does not recommend herbal supplements for blood sugar benefit (ADA Standards of Care 2026, Sec. 5). Keep your prescribed care and talk to your doctor.
