This page has two jobs. First, it explains every line printed on the Supplement Facts panel of the box we write about, what each one is, and what the research does and does not say about it. Second, it lists the headlines we run, tells you which ones overreach, and separates the few things that are genuinely supported from the many that are not.
You almost certainly arrived here from an advertisement. The headline you clicked was written by us and paid for by us to appear next to real news stories. It was designed to make you stop scrolling, and some of our headlines lean harder on a story than the evidence does.
Everything on this site is a paid advertisement for a product sold by someone else. If you buy through a link on any of our pages, we may be paid a commission. That is the reason this site exists.
The product is Gluco Stix, a powder sold in single-serve sticks by Allseason Enterprises LLC, doing business as Clean Nutra, of Las Vegas, Nevada: twenty 2.2-gram sticks in a box, rainbow sherbet flavor, poured straight onto the tongue with no water. The panel prints chromium, vitamin D3, vitamin C, konjac glucomannan, Ceylon cinnamon and green tea with amounts, plus a 50 mg blend whose label name is "Proprietary Blood Sugar Blend." That name is a name, not a finding: no study has ever tested this stick, and the seller's page carries the standard statement that its claims have not been evaluated by the Food and Drug Administration. Nothing on this page is a substitute for your own clinician or for anything your clinician has given you.
If your last checkup came with a direction about your numbers, the single most useful thing you can do is ask your clinician what to watch, and walk after supper. That costs you nothing from us, and it is worth more than anything we write about.
| The headline as you saw it | What is actually behind it |
|---|---|
| "The Copper Kettle Went Up on the Shelf the Week Loretta Opened Her Purse" | Story, not a claim The box is real; Earl, Carol and Loretta are composites, and the column is a dramatization built on the seller's listing, panel, reviews and return policy. |
| "Proprietary Blood Sugar Blend" | Exaggerated The label's name for a 50 mg blend of six items, not its evidence. Nobody has tested this blend, and the label does not say how much of each item is inside; on average that is about eight milligrams each. |
| "Eleven nutrients and botanicals in every stick" | Broadly supported The panel lists chromium, vitamin D3, vitamin C, glucomannan, Ceylon cinnamon, green tea, chicory root, myo-inositol, berberine, fenugreek and raspberry and strawberry juice powders. Eleven, if the berries count as two. |
| "No water, no kettle: tear, pour, enjoy" | Broadly supported The seller's directions say to pour one stick directly into the mouth, with no water or mixing, once daily or as directed. That is a statement about convenience, not about results. |
| "About two dollars a stick" | Broadly supported $39.95 for one box of 20 sticks, checked against the listing in October 2026. Two boxes at $51.70 come to about $1.29 a stick; three at $99.95 about $1.67; five at $149.95 about $1.50. |
| "A driver's habits got better in six weeks" | Story, not a claim A composite log of habits, not lab numbers. Our column says plainly that it cannot tell which part of the routine did what, and that the real test belongs to the reader's clinician. |
Because stories stop the scroll better than ingredient lists do. That is exactly the problem. We keep the honest version of every claim here so you can compare it with the ad side by side.
The seller's refund policy page gives 180 days from the purchase date to send a product back for a refund, excluding shipping. Used and unused packages are accepted, with a limit of two unused packages per return and one refund per product per household.
The seller's pages do not agree with each other on the length: the Terms of Service mention "up to one year," and the FAQ says 180 days on opened and unopened. We go by the refund policy page and suggest you write the date on your calendar the day you order. The website lists [email protected] and a mailing address; the phone number (866) 221-7374 is printed on the side of the box, not on the website.
Largest line on the panel · Ongoing research
An essential trace mineral involved in how the body handles carbohydrates, fats and proteins. The NIH Office of Dietary Supplements calls its role in insulin signaling an area of ongoing research, and the FDA allows only a qualified claim for chromium picolinate, meaning the agency itself says the evidence is limited. The panel prints 2,857 percent of the Daily Value; no upper limit has been set, and it is a number worth showing your clinician.
The best-known name · Mixed
The NIH's complementary-health center says research in people shows mixed results, with some reviews reporting modest changes in fasting numbers and others finding no meaningful effect, and that there is not enough evidence to conclude cinnamon helps with any health condition. Ceylon cinnamon carries much less coumarin than the cassia kind.
Inside the 50 mg blend · Made by the body
Once counted among the B vitamins, it is no longer considered essential because the body makes its own from glucose, up to four or five grams a day, mostly in the kidneys. Whatever share of the 50 mg blend it takes up is small next to that.
A tea plant · Contains some caffeine
Green tea comes from the same plant as black and oolong tea and naturally contains caffeine. The panel does not print a caffeine figure for this extract.
A root fiber · Small amount
A soluble fiber from the root of the konjac plant, the one used for clear konjac noodles. The seller says its fiber-rich ingredients support satiety and digestive comfort; 50 mg is a small pinch of fiber, far below a spoonful.
Inside the 50 mg blend · Label ingredients
Berberine is a yellow compound from the bark of Indian barberry, Berberis aristata; fenugreek is the maple-scented seed of curry powder; chicory root is mostly inulin, a fiber. All three share the 50 mg blend with myo-inositol and two berry powders, with no amounts printed. They are listed on the label as ingredients, and that is all we say about them.
Two vitamins · Check what you already take
Vitamin D3 at 62.5 micrograms is 2,500 IU, printed as 313 percent of the Daily Value; vitamin C at 45 mg is half the Daily Value. If you already take a multivitamin or a vitamin D product, add the amounts up before you start.
Eleven names on a 2.2-gram stick, most with amounts printed and one 50 mg blend without. One mineral with ongoing research, one spice with mixed results, one compound the body already makes by the gram, small amounts of the rest, and no study on this stick. A convenient pocket routine, not a plan for your numbers.
Our column quotes the blend's label name as a name. Here is the plain truth: no clinician, no panel and no medical society has endorsed this page or this box. The seller's listing says the sticks are "designed to support balanced wellness and healthy glucose metabolism," and we quote that sentence only as the seller's own words.
The seller's page carries the statement that its claims have not been evaluated by the Food and Drug Administration and that the product is not intended to stand in for medical care. That is the sentence that outranks every other sentence we print.
None of our ads should be your health information. If your checkup came with a direction about your numbers, the people to talk to are your clinician and your pharmacist, and the things to bring are your questions and any notes you keep. See your clinician promptly if you notice unusual thirst, frequent urination, blurred vision, cuts that are slow to close, or tiredness that is new for you.
If you already take anything daily for your numbers, tell your clinician before adding any supplement, and show the box to your pharmacist. Chromium, cinnamon and berberine are the three names we would say out loud. If you are expecting or nursing, ask first. Keep the box away from dogs: the sweetener xylitol is dangerous for them.
Every line printed on the panel, in the order printed, with what it is.
A trace mineral present in tiny amounts in meat, whole grains, broccoli, grape juice and brewer's yeast. Picolinate is chromium bound to picolinic acid, a common supplement form. The National Institutes of Health notes that chromium's role in the body is not fully settled and that a shortage is hard to identify.
Traditional and everyday use. No traditional use.
What the research says. No trial of this ingredient on memory or attention in healthy older adults is on file. Descriptive only.
Amount per serving in Gluco Stix. 1000 mcg (2857% DV)
Good to know. No upper limit has been set; a few reports of kidney problems and of harm to the organ that processes what you swallow exist with high doses of chromium picolinate. Anyone who takes anything daily for glucose, and anyone whose clinician is watching the kidneys or the organ that processes what you swallow, should ask a clinician or the pharmacist.
The 'sunshine vitamin': the skin makes it from sunlight, and it is added to milk and found in fatty fish and egg yolk. It regulates calcium and bone. Many older adults in northern latitudes have low blood levels in winter.
Traditional and everyday use. No traditional use; identified in the 1920s.
What the research says. In the three-year DO-HEALTH trial of 2,157 adults aged 70 and older, 2,000 IU a day of vitamin D3 produced no statistically significant benefit on a cognitive screening score, alone or combined with omega-3s and exercise.[1] Correcting a real deficiency is a matter for a blood test and a doctor, not for a memory page.
Amount per serving in Gluco Stix. 62.5 mcg (313% DV)
Good to know. Safe at label doses; the tolerable upper level for adults is 100 mcg (4,000 IU) a day. Too much over time raises blood calcium.
A water-soluble vitamin found in citrus, peppers, berries and leafy greens. The body cannot make it and does not store much of it, so it has to come in with the food every day. Labels print it as ascorbic acid or bound to a mineral, as in magnesium ascorbate.
Traditional and everyday use. Citrus and fresh greens have been eaten against scurvy since the days of sailing ships.
What the research says. The Daily Value printed on US labels is 90 mg.[2] We cite no trial of vitamin C alone for this entry, which stays descriptive.
Amount per serving in Gluco Stix. 45 mg (50% DV)
Good to know. Amounts above about 2,000 mg a day can upset the stomach; if you take anything daily, or have been told to limit vitamin C, ask your pharmacist before taking large doses.
The dried inner bark of tropical trees, rolled into quills or broken into chips. Two kinds are sold: Ceylon or "true" cinnamon, grown mainly in Sri Lanka, and cassia cinnamon, the most common kind in North America. This tin does not say which one it uses.
Traditional and everyday use. A kitchen spice on every continent and the sweet note in chai.
What the research says. The National Institutes of Health states that research doesn't clearly support using cinnamon for any health condition. We make no claim for it here.
Amount per serving in Gluco Stix. 33.4 mg
Good to know. Cassia cinnamon contains coumarin, and prolonged intake of high-coumarin products is a concern for the organ that processes what you swallow; Ceylon cinnamon carries only a trace. Since the tin does not say which kind it uses, ask your doctor before drinking it daily if you take anything daily.
The leaves of the tea plant, dried without the oxidation that turns the same leaves into black tea. Green, black and oolong teas all come from this one plant; only the processing differs.[3] It is the first ingredient printed on this tin, so it is very likely the bulk of the blend.
Traditional and everyday use. Drunk daily across Asia for centuries, and the base of most flavored tea blends sold today.
What the research says. Green tea carries caffeine and a small amount of the amino acid L-theanine. In one study in adults aged 50 to 69, a single dose of L-theanine was associated with a faster reaction time on an attention task and fewer errors on a working-memory task.[4] The summary of that study does not state the dose, and the tin does not state how much green tea is in a teaspoon. The National Institutes of Health notes that green tea contains caffeine, that harm to the organ that processes what you swallow has been reported mainly with green tea extracts in tablet or capsule form rather than with the drink, and that green tea may reduce the effectiveness of some medicines.[3]
Amount per serving in Gluco Stix. 33.33 mg
Good to know. It contains caffeine, so it is a daytime cup, not a bedtime one, and worth limiting if caffeine unsettles your heart or your stomach. Green tea may reduce the effectiveness of some medicines (the NIH names nadolol, atorvastatin and raloxifene).[3] Talk to your doctor or pharmacist before drinking it daily if you take anything daily, or if you are pregnant or nursing.

Nobody honest can promise that, and the seller's FDA statement says its claims have not been evaluated. Our column describes one composite reader whose habits improved over six weeks, and he could not say which part of the routine mattered.
Because that is the name the seller chose. A label name is marketing, not evidence, and this guide exists to keep the two apart.
The seller's directions say no water or mixing is required. Drink water whenever you like; the stick does not need it.

This guide is part of the advertising page it links from. It exists because the ad that brought you here did not tell you the whole story.
If you remember nothing else: this is a no-water powder stick with eleven names on its panel, most with amounts and one small blend without, the research on its best-known ingredients ranges from ongoing to mixed, its blend's name is not a finding, its returns run 180 days, and your clinician outranks all of us.
