Quick verdict

Gluco6 is a simple one-capsule-a-day formula, and unlike many blood sugar supplements it shows a full Supplement Facts label on its order page. Its strongest ingredient on paper is chromium, at a high 1 mg dose, alongside cinnamon, gymnema, green tea extract and L-arabinose, all of which have some research behind them. The research is weak, though, the herb amounts are hidden inside a 525 mg blend, and the sales copy makes weight loss and "ditch your meds" promises that no supplement can keep. It suits adults with mildly raised blood sugar who have spoken to their doctor, not people looking to replace treatment.

The bottle says Good Mix Naturals Gluco 6 Advanced Formula; the website calls it Gluco6. It is the same product.

Gluco6 is a daily capsule sold to support healthy blood sugar. The sales page highlights six ingredients (Sukre, chromium, cinnamon, TeaCrine, gymnema and green tea), but the label image on the same page lists more: chromium 1 mg, vitamin D3 2,000 IU and vitamin B1 100 mg, plus a 525 mg blend of L-arabinose, theobromine, green tea extract, eleuthero, theacrine, cassia cinnamon and gymnema. You take one capsule in the morning. It is sold through gluco6.com at $39 to $69 per bottle as a one-time payment, with a 60-day money-back guarantee. This review covers the label, the evidence for each ingredient, the price, the refund fine print and, most important, the safety points for anyone already on diabetes medicine.

First, a word about blood sugar

High blood sugar rarely causes symptoms early on, which is why many people find out about prediabetes or type 2 diabetes from a routine blood test. If you have not had an A1C or fasting glucose test recently, start there: it tells you where you stand and gives you a number to compare against later.

If you already have diabetes, your medicine is doing a job that no supplement has been shown to do. NCCIH is blunt about this: it is very important not to replace diabetes treatment with an unproven product, and the FDA warns about products that promise to replace diabetes medicine. Gluco6 is a dietary supplement, not a treatment for diabetes. Never lower or stop metformin, insulin or any other diabetes drug without your doctor, and watch for signs of low blood sugar (shakiness, sweating, confusion, a racing heart) if you add a supplement like this one.

What is inside Gluco6?

We read the Supplement Facts panel from the label image on the official order page (it is marked "sample", so compare it with the bottle you receive). Here is each ingredient next to what the research actually supports.

Ingredient (per capsule)	What the brand says	What research supports
Chromium (as chromium niacinate), 1 mg	Enhances insulin sensitivity, helps burn fat	A 2022 review of 16 trials suggested small improvements in HbA1c and fasting glucose in type 2 diabetes. NCCIH calls the evidence weak. 1 mg is about 28 times the daily value.
Vitamin D3, 50 mcg (2,000 IU)	Not described on the sales page	Useful if you are low. In diabetes reviews the effect on blood sugar was small and below what doctors consider meaningful.
Vitamin B1 (thiamine), 100 mg	Not described on the sales page	Essential vitamin; no good evidence that extra thiamine lowers blood sugar in people who are not deficient.
Sukre™ (L-arabinose)	"Manipulates glucose movement out of the bloodstream"	L-arabinose slows the enzyme that digests table sugar. A small Japanese study cited by the brand found a lower glucose rise when it was eaten with a sucrose-containing food.
Green tea extract (98% polyphenols, 65% EGCG)	Improves glycemic control	Mixed, modest results. NCCIH notes rare liver injury from concentrated green tea extracts.
Cinnamon (cassia) bark	Enhances insulin sensitivity, suppresses appetite	NCCIH says it is unclear whether cinnamon helps diabetes; cassia contains coumarin, a concern for people with liver disease.
Gymnema sylvestre leaf	Blocks sweet taste, supports glucose levels	Gymnema dulls sweet taste when it touches the tongue; a swallowed capsule does not. Small glucose studies exist; evidence is limited.
Theacrine (TeaCrine®)	Supports glucose metabolism, focus and energy	A caffeine-like compound studied for energy and mood; we found no good human evidence for blood sugar.
Theobromine, eleuthero root	Not described on the sales page	Theobromine is the mild stimulant in cocoa; eleuthero is a traditional "adaptogen". Neither has solid blood sugar evidence.

Gluco6 Supplement Facts label — Gluco6 Supplement Facts panel, as published on the official website.

Label note: The label states individual amounts only for vitamin D3 (50 mcg), vitamin B1 (100 mg) and chromium (1 mg). The other seven ingredients (L-arabinose, theobromine, green tea extract, eleuthero, theacrine, cassia cinnamon and gymnema) share a 525 mg proprietary blend per capsule with no per-ingredient amounts. The label image on the order page is marked "sample".

Two things stand out. The seven blend ingredients share 525 mg, so there is no way to know whether you get a meaningful dose of cinnamon or gymnema, which were usually studied at hundreds of milligrams to grams a day. And the chromium dose is high: 1,000 mcg against a daily value of 35 mcg. That is within the range used in studies, and the FAQ itself warns against stacking Gluco6 with other chromium-rich formulas, so check any multivitamin you take.

Every ingredient, up close

Here is every active ingredient on the label, what it actually is, and what research does and does not show.

Chromium (as chromium niacinate)

1 mg

An essential trace mineral (pictured: broccoli, a common food source of chromium). NCCIH summarizes a 2022 review of 16 studies with 868 people with type 2 diabetes that suggested chromium may improve HbA1c, fasting glucose and insulin resistance, but calls the evidence weak because the studies were small and varied. At 1 mg (1,000 mcg), about 28 times the Daily Value, the dose is within the range used in studies, which is also why the FAQ warns against stacking Gluco6 with other chromium products; most people in the US are not deficient, so any benefit is likely modest.

Vitamin D3

50 mcg (2,000 IU)

The form of vitamin D the skin makes in sunlight (pictured: salmon fillet, a common food source of vitamin D). It is useful if your level is low, but in diabetes reviews the effect on blood sugar was small and below what doctors consider meaningful. 2,000 IU is above the 600 to 800 IU recommended daily amount and below the 4,000 IU upper limit the NIH sets for adults, so count any other vitamin D you take.

Vitamin B1 (thiamine)

100 mg

Vitamin B1, which the body needs to turn carbohydrates into energy (pictured: sunflower seeds, a common food source of thiamine). 100 mg is many times the roughly 1.2 mg adults need a day; there is no good evidence that extra thiamine lowers blood sugar in people who are not deficient.
