Three of the exclusions on this page are about ingredients whose amounts are not printed.
Glyco Harmony is made for healthy adults over 18 who want a daily liquid blood sugar supplement.
Talk to a clinician first if you take medication for blood sugar, blood pressure or the heart, take a corticosteroid, have hypertension or a kidney condition, or are pregnant or nursing.
Read the label cautions.
Blood Sugar Support* and nothing else on the front. No numbers promised, no disease named, the asterisk pointing at a real disclaimer. Judged as a piece of regulated writing, the bottle is better behaved than most in this category.
Some people cannot swallow capsules, and this is a straightforward glycerin-and-water dropper preparation, sweetened with stevia and xylitol rather than sugar. That is a real reason to choose a format, and it is independent of what is dissolved in it.
Nine of them, named: glycerin, water, organic lemon extract, stevia 97% Reb A, xylitol, sodium benzoate, potassium sorbate, citric acid and natural flavors. A liquid needs preservatives and this label prints them instead of hiding behind proprietary base.
A phone number and an email are printed on the bottle itself, and the desk selling it publishes a second number, two New York addresses and a 60-day window. Not every product reviewed here gives you a way to reach anybody.
Made in the USA with globally sourced ingredients, printed on the label rather than only on a badge. That is the qualified construction the FTC describes, and it is more honest than the unqualified roundel the listing puts beside it.
Stevia and xylitol rather than sugar or a syrup. On a product bought by people watching blood glucose, that is a sensible formulation decision and it is disclosed.
Then the arithmetic settles it before anything else. This bottle delivers 0.7 micrograms per 1 ml serving. The NIH lists trials of chromium and glucose at 1.28 to 1,000 mcg a day, says a typical multivitamin carries 35 to 120 mcg, and says chromium supplements commonly provide 200 to 500 mcg. There is no reading of those figures on which 0.7 is a dose.
Eighth of twenty-two in a 200 mg blend, so at most 25 mg, with no standardisation printed. The studies the monograph describes used 200 or 400 mg a day of extract standardised to 25% gymnemic acids, or 500 to 1,000 mg a day of leaf extract.
This is the one we would be most careful about. NCCIH says Asian ginseng “might lower blood sugar levels” and that anyone with diabetes should consult their health care provider before using it, and warns that using herbal supplements alongside conventional diabetes drugs “can cause unwanted side effects”. The ginseng here has no printed amount, so nobody — including your pharmacist — can size the question.
The blend contains monoammonium glycyrrhizinate. NCCIH says glycyrrhizin “can cause serious adverse effects, such as irregular heartbeat and cardiac arrest”, and that even small amounts have been linked to severe adverse effects in people with hypertension, a high salt intake, or heart or kidney conditions. The amount is not published.
NCCIH records that “interactions between licorice and corticosteroids have been reported”. Same ingredient, same missing number.
The label's caution panel tells pregnant or nursing mothers and children under 18 to consult a physician before using this or any dietary supplement. We would follow it.
The general case, and the one this bottle fails hardest. Twenty-three named ingredients, one printed amount, no standardisations anywhere, and a dosing instruction that offers one dropper or two without saying how much a dropper holds. Every figure on this site that looks like a dose is a ceiling we calculated from the order the ingredients are printed in.
Nothing you answer leaves your browser. Three of the five are about medication and blood pressure, and that is deliberate.

A ceiling is not an amount, and on these three that is the whole problem.
Monoammonium glycyrrhizinate. Eighteenth of twenty-two, so at most 11.1 mg. It is a salt of glycyrrhizic acid, the compound in licorice root. NCCIH writes that glycyrrhizin “can cause serious adverse effects, such as irregular heartbeat and cardiac arrest”, and that “even small amounts of glycyrrhizin from licorice root products have been linked to severe adverse effects in people who consume a lot of salt, in people with hypertension”, and in people with heart or kidney conditions. It adds that “interactions between licorice and corticosteroids have been reported”.
Panax ginseng aerial extract. Twelfth of twenty-two, so at most 16.7 mg. NCCIH: “Some evidence suggests that Asian ginseng might lower blood sugar levels.” And: “If you have diabetes, consult your health care provider before using Asian ginseng.”
Guarana and green tea. Third and seventh by weight, both caffeine sources, neither carrying a caffeine figure. The amount is probably small. The point is that the label does not let you establish it.
Now the part that turns those from footnotes into a problem. A ceiling is not an amount. A pharmacist can tell you whether 10 mg of a glycyrrhizin salt matters alongside your blood pressure medicine. Nobody can tell you whether somewhere between a trace and 11.1 mg matters, because that is not a question with an answer.
And there is an arithmetic wrinkle specific to this bottle: at two droppers a day, every one of those ceilings doubles.
Photograph the panel and show it to whoever manages your prescriptions before the first dose. That is the label's own instruction, phrased as a practical step. It is free, it takes a minute, and on this formula it is the single most useful thing on this page.
Somebody who has read about a specific ingredient and gone looking for it.
If you read the chromium literature and want the 200 to 1,000 micrograms that chromium supplements commonly provide, this bottle gives you 0.7. If you read the gymnema trials and want 400 mg of extract standardised to 25% gymnemic acids, this bottle caps gymnema at 25 mg and prints no standardisation at all.
A proprietary blend is worst for the informed buyer, which is a strange thing for a product in this category to be. Somebody who knows nothing loses nothing they were aware of. Somebody who has done the reading finds that the one piece of information their reading prepared them to use is the piece that is missing.

Everything above is either printed on the label or quoted from a named source we opened. None of it is a judgement about your health, which we are not qualified to make and have no information to make it with. If any row in that table describes you, the useful next step is the panel in front of a pharmacist, not another article.
Glyco Harmony is a blood sugar supplement in 2 fl oz dropper bottles. Its panel prints one amount — chromium, 0.7 micrograms — and puts twenty-two further ingredients inside a 200 mg blend with no individual figures. We publish the gap rather than filling it.
Order NowRead the label firstFor a healthy adult taking the label dose, the individual ingredients are in common use and the amounts involved are small. Whether it is safe for <i>you</i> is harder than it needs to be, because twenty-two of the twenty-three ingredients carry no amount — including a licorice derivative and a botanical that may lower blood sugar. The caution panel tells anyone with a known medical condition to consult a physician first, and on this formula that is the right instruction. We are not clinicians and this is not medical advice.
Ask the person who prescribes it, and take the bottle with you. NCCIH says Asian ginseng might lower blood sugar levels and that anyone with diabetes should consult their health care provider before using it, and warns that using herbal supplements alongside conventional diabetes drugs can cause unwanted side effects. Because no amount is printed, nobody can size that question from the label.
It is the reason we would want the glycyrrhizinate quantified. NCCIH writes that even small amounts of glycyrrhizin from licorice root products have been linked to severe adverse effects in people with hypertension and in those who consume a lot of salt. The ceiling here is 11.1 mg and the actual amount is not published.
NCCIH records that interactions between licorice and corticosteroids have been reported. Same ingredient, same missing number, same answer: that is a pharmacist question before the first dropper.
We cannot say, and neither can the label. What can be quoted is NCCIH on Asian ginseng: “Some evidence suggests that Asian ginseng might lower blood sugar levels.” If you already take something that lowers blood sugar, an unquantified second thing that might is a conversation to have in advance rather than afterwards.
Almost certainly a small amount, and the label will not tell you how much. Guarana is third by weight in the blend and green tea seventh, and both contain caffeine; neither carries a caffeine figure. The FDA cites 400 mg a day as the amount not generally associated with dangerous negative effects in healthy adults, and you cannot add an unknown to that sum.
The label's caution panel says pregnant or nursing mothers should consult a physician before using this or any dietary supplement. We would follow it.
The caution panel says children under the age of 18 should consult a physician before use. The brief is firmer and says it is for adults 18 and over.
Monoammonium glycyrrhizinate, eighteenth of twenty-two, so at most 11.1 mg. It is a salt of glycyrrhizic acid, the compound in licorice root. NCCIH says glycyrrhizin “can cause serious adverse effects, such as irregular heartbeat and cardiac arrest”, and that “even small amounts” have been linked to severe adverse effects in people with hypertension, a high salt intake, or heart or kidney conditions. The amount here is not published.
Twelfth of twenty-two, so at most 16.7 mg. NCCIH reports that Asian ginseng improved several cardiometabolic factors including fasting blood glucose, while calling the research on blood sugar control in people with diabetes “inconclusive and conflicting”. Its practical note is the one to read: “If you have diabetes, consult your health care provider before using Asian ginseng.” Note also that this is the <i>aerial</i> extract rather than the root most research uses.
