The product
GlucoZen is a liquid dietary supplement in a 2 fl oz amber glass dropper bottle, labeled Blood Sugar Support. One serving is 1 mL, taken twice a day, so a bottle of 60 servings lasts 30 days.
GlucoZen is a liquid dietary supplement in a 2 fl oz amber glass dropper bottle with an aqua label that reads "Blood Sugar Support." One serving is 1 mL, taken twice a day, so a bottle of 60 servings lasts 30 days.
The label lists one nutrient with an amount, chromium at 0.7 mcg, and one "Proprietary Herbal Blend" of 200 mg holding 22 ingredients: maca, grape seed, guarana, African mango, eleuthero, astragalus, green tea, gymnema, forskohlii, bird pepper, grapefruit seed, Asian ginseng, raspberry ketones, eight amino acids and a licorice compound. Stevia and xylitol sweeten it.
The brand's own marketing tells a different story, with berberine, cinnamon, Okinawa honey and probiotics. This site goes by the bottle. Start with the full Supplement Facts or the label versus marketing page.
It is a long blend of small amounts, plus a trace of chromium. No trial of GlucoZen exists, and the American Diabetes Association does not recommend herb, spice or chromium supplements for blood sugar.
Label vs marketing
No. The bottle label lists neither berberine nor cinnamon. The brand info site and one graphic name seven other ingredients, such as Okinawa honey and probiotics, and none of them is on the Supplement Facts panel. Go by the label.
"About five drops in warm water before breakfast, once daily"
"Adults, take 1 mL (approximately 2 droppers full) twice daily"
Not one of the seven ingredients named in the marketing appears on the Supplement Facts panel. Go by the label on the bottle you receive.
The brand info site and the "Inside GlucoZen" graphic name seven ingredients, with "about five drops in warm water before breakfast, once daily" (glucoszen.com). The Supplement Facts panel lists none of them and says 1 mL twice daily. Berberine does have some evidence for modest blood sugar effects (NCCIH, Berberine), but that evidence does not apply to a bottle without berberine. Full details on the label versus marketing page.
Daily routine
Take 1 mL of GlucoZen, about 2 droppers full, in the morning and again in the evening, and never more than 2 mL a day. The label sets no meal timing. Keep your usual glucose checks.
The label serving is 1 mL, about 2 droppers full. The bottle holds 60 servings.
Take 1 mL in the morning. The label sets no meal timing; the brand site's "five drops before breakfast" does not match the label.
Take the second 1 mL in the evening. Never more than 2 mL a day.
Keep your usual glucose checks and lab visits. Bring your log to your clinician.
Blood sugar shifts with meals, sleep, stress, activity and medicines. If you start any supplement, keep your usual glucose checks and lab visits so you and your clinician can see what is really happening. A log of readings tells you more than any label claim.

The label
The GlucoZen label prints a 1 mL serving, 60 servings per 2 fl oz bottle, chromium at 0.7 mcg and one 200 mg proprietary herbal blend of 22 ingredients with no single amounts. Tap a number to decode each line.
1 mL per serving, 60 servings per 2 fl oz bottle. At 1 mL twice daily, a bottle lasts 30 days.
The only printed amount: 0.7 mcg, 2% of the Daily Value. Twice daily is 1.4 mcg, about 4%.
Twenty-two ingredients share 200 mg, about 9 mg each on average. No single amounts are printed.
Maca, grape seed and guarana come first, so they are the largest shares of the blend.
Guarana and green tea both contain caffeine. The caffeine amount is not printed.
The herb most tied to blood sugar claims. Eighth in the list: at most 25 mg per serving.
Bird pepper (capsicum), grapefruit seed and Asian ginseng, each a small share.
Eight amino acids close the list: the smallest shares of the blend.
Monoammonium glycyrrhizinate, a licorice-derived sweetener with a blood pressure caution.
Water, organic citrus extract, natural flavors, stevia and xylitol. Xylitol is dangerous to dogs.
Every line is typed out on the Supplement Facts page, with what each one means.
Directions and warnings
The directions say adults take 1 mL twice daily, or as a healthcare professional directs, and do not exceed 2 mL a day. The label says not for under 18 or pregnant or nursing mothers, and to ask a physician first.

Ingredients
GlucoZen lists chromium plus a 200 mg blend of 22 ingredients, among them maca, grape seed, guarana, gymnema, green tea and Asian ginseng. Stevia and xylitol sweeten it. Tap a card for details on each profile.
On the label: Chromium (as Chromium Picolinate) · 0.7 mcg per 1 mL (2% DV); 1.4 mcg a day
The headline mineral in many blood sugar formulas
Tiny dose; ADA does not recommend it for glucoseEssential trace mineral, the only printed amount. Adults need about 25-35 mcg a day; glucose trials are inconsistent.
Watch forChromium can add to insulin and other diabetes drugs. The amount here is tiny, but tell your clinician.
Full profileOn the label: Gymnema (leaf) extract (Gymnema Sylvestre) · Not printed (at most 25 mg per serving by label order)
Marketed for blood sugar and sugar cravings
Weak; not shown to treat diabetesAyurvedic herb. Small trials showed mild drops in fasting glucose; a typical dose is 400 mg three times a day.
Watch forCould add to diabetes medicines. Rare liver injury has been reported.
Full profileOn the label: Asian Ginseng (root) extract (Panax Ginseng), Eleuthero (root) extract · Not printed (at most about 17 mg and 40 mg)
Marketed for energy and blood sugar
InconclusiveRoot herbs. Ginseng's blood sugar research is inconclusive and conflicting; eleuthero's human studies are limited.
Watch forGinseng may affect blood clotting; eleuthero raised digoxin levels in a case report. Insomnia is common.
Full profileOn the label: Guarana (Paullinia cupana) Seed Extract · Not printed (at most about 67 mg of extract per serving); caffeine not printed
Energy and metabolism angle
Caffeine, not a blood sugar herbNatural caffeine source. Most of guarana's effects come from caffeine; 400 mg of caffeine a day is the usual adult ceiling.
Watch forAdds an unknown amount of caffeine, on top of green tea. Avoid with other stimulants; ask first if you take a blood thinner.
Full profileOn the label: Green Tea (Camellia sinensis) Leaf Extract · Not printed (at most about 29 mg per serving)
Marketed for metabolism
A safety flag, not a benefitLeaf extract with caffeine. Extract pills are a well-established, rare cause of liver injury.
Watch forStop and call a clinician for dark urine, yellow skin or eyes, or belly pain.
Full profileOn the label: Monoammonium Glycyrrhizinate · Not printed (at most about 11 mg per serving)
Probably sweetness and flavor
A safety flag, not a benefitLicorice-derived sweetener. Glycyrrhizin can cause heart rhythm problems, more likely with large amounts or long use.
Watch forPeople with high blood pressure, heart or kidney disease, or a salty diet should ask a clinician first.
Full profileOn the label: L-Glutamine, L-Tyrosine, L-Arginine, Beta-Alanine, GABA, L-Ornithine HCl, L-Tryptophan, L-Carnitine · Not printed (at most about 14 mg down to 9 mg each)
Likely there to lengthen the list
Tiny amounts; little relevanceAmino acids. Food sources supply far more; L-arginine may lower blood sugar; L-tryptophan products were recalled in 1989.
Watch forL-arginine with nitrates or sildenafil can drop blood pressure too low. Ask first if you take either.
Full profileOn the label: Other Ingredients: Deionized Water, Organic Citrus Extract, Natural Flavors, Stevia (Steviol Glycosides), Xylitol · Not printed
Sweeten the drops without sugar
Sweeteners, not activesSweeteners and base. Xylitol does not raise insulin in people but is dangerous to dogs; high-purity stevia is GRAS.
Watch forKeep the bottle away from dogs: xylitol can drop a dog's blood sugar within an hour. Call a vet right away if a dog gets into it.
Full profileThe remaining blend ingredients, maca, grape seed, African mango, astragalus, forskohlii, bird pepper, grapefruit seed and raspberry ketones, each have their own short entry on the ingredients page. None has strong evidence for blood sugar (NIH ODS, Weight loss supplements) (NCCIH, Astragalus).
Blend math
GlucoZen prints no single amounts for its 22 blend ingredients, which share 200 mg per 1 mL, about 9 mg each on average. The order of the list only sets a ceiling for each one.
Blend ingredients are listed from heaviest to lightest (FDA, Labeling guide), so the ingredient in place k can weigh at most 200 ÷ k mg per serving. That is our math from the label, not a lab test. Chromium sits outside the blend with its own amount: 0.7 mcg.
Twenty-two ingredients in 200 mg leaves about 9 mg each on average. At the labeled two servings a day, the whole blend is 400 mg, a third of the 1,200 mg daily dose LiverTox lists for gymnema alone (LiverTox, Gymnema).
Dose check
GlucoZen has 0.7 mcg of chromium per 1 mL. At the labeled 1 mL twice daily that is 1.4 mcg a day, about 4% of the Daily Value. Chromium is the only ingredient with a printed amount.
Adults need about 25 to 35 mcg of chromium a day, and most get it from food (NIH ODS, Chromium). GlucoZen's 1.4 mcg a day is about 4% of the Daily Value. The ADA's 2026 Standards of Care say chromium, magnesium, herb and spice supplements are not recommended for blood sugar benefit (ADA, Standards of Care 2026).
Know your numbers
An A1C of 5.7% to 6.4%, or a fasting glucose of 100 to 125 mg/dL, falls in the prediabetes range. No study shows GlucoZen changes these numbers, so review any lab result with your clinician.
About 115.2 million U.S. adults have prediabetes, and 40.1 million people have diabetes (CDC, Diabetes statistics). In a large trial, a lifestyle program cut the chance of type 2 diabetes by 58% (NIDDK, DPP). Read more in the prediabetes guide.
A day with it
Take GlucoZen in the morning and in the evening, 1 mL each time, and no more than 2 mL a day. The label names no meal timing. A walk after meals does more of the work than any drops.
About 2 droppers full.
The second serving. No more than 2 mL a day.
Activity is part of the program that cut diabetes risk by 58%.
A steady routine helps you read your numbers.
Lifestyle program results (NIDDK, DPP).
Claims and evidence
No study of GlucoZen exists, so its effect on blood sugar is not shown. The chromium dose is tiny, the herbs are in small hidden amounts, and the ADA does not recommend herb, spice or chromium supplements for blood sugar.
No study of GlucoZen exists. The ADA's 2026 Standards say herb, spice and chromium supplements are not recommended for blood sugar benefit.
(ADA, Standards of Care 2026) (ADA, Vitamins and supplements)
The brand's graphic names ingredients the Supplement Facts panel does not list. Any evidence for berberine does not apply to this bottle.
Gymnema showed mild fasting glucose drops in small trials at doses far above what fits here. Raspberry ketone and forskohlii showed little.
Natural does not mean risk-free: green tea extract, licorice and caffeine carry cautions, and some ingredients may add to diabetes medicines.
Claims are paraphrased from the label front, the brand graphics and the brand info site. Under FTC guidance, health claims need competent and reliable scientific evidence, generally human trials. (FTC, Health Products Compliance Guidance)
No trial of GlucoZen has been published. The ADA says supplements are not proven to lower blood glucose and some can intensify diabetes medicines (ADA, Vitamins and supplements). The full breakdown is on the claims and evidence page.
Research
GlucoZen's blend has no trials found. Chromium, gymnema and ginseng have small, mixed trials, and a lifestyle program has the strongest evidence on the ladder. Higher rungs mean stronger evidence.
Higher means stronger evidence for preventing or managing type 2 diabetes. In the Diabetes Prevention Program, the lifestyle program beat metformin; no supplement was tested.

Fair verdict
Pros: the full ingredient list is printed, the drops are sweetened with stevia and xylitol, and the sales site gives a written 60-day refund window. Cons: the marketing names ingredients the label does not list, and the blend amounts are hidden.
Weigh it the way you would any supplement: read the label, keep your diabetes care, and talk to your clinician (FDA, Dietary supplements Q&A).
Quick check
GlucoZen is for adults 18 and over. Ask a clinician first if you are pregnant or nursing, take insulin or diabetes pills, or have liver, heart or kidney problems. Keep the bottle away from dogs. This checklist is not medical advice.
