Glucotide Side Effects: The Printed Warning and Cautions
The Glucotide label prints no side-effect list, but it does carry a warning about licorice root.
Licorice may raise blood pressure at high doses, so the label says it is not for people with hypertension, heart, liver or kidney conditions, or for long use without medical supervision. If you take blood thinners (vitamin E) or have lab tests coming up (biotin), tell your doctor.
Check whether the label names you on who Glucotide is for.

Cautions
The printed warning, first and in full
Everything this label and our sources say about who should be careful, with the source lines quoted rather than summarised.
Printed on the bottle
WARNING: Licorice root may elevate blood pressure at high doses. Not for use by persons with hypertension, heart disease, liver or kidney disorders, or for prolonged periods without medical supervision.
That sentence is on the label and it is in none of the marketing supplied with this stock. The ingredient it concerns is licorice, which is first in the 82 mg proprietary blend. NCCIH’s licorice root page carries the same concern in more detail, and the three lines below are quoted from it exactly.
NCCIH on glycyrrhizin
“Licorice contains a component called glycyrrhizin, or glycyrrhizic acid, that can cause serious adverse effects, such as irregular heartbeat and cardiac arrest, especially when consumed in large amounts or in the long term.”
NCCIH on small amounts
“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.”
NCCIH on corticosteroids
“Interactions between licorice and corticosteroids have been reported.”
Read the second of those carefully, because it is the one that does the most work. The concern is not only about large amounts. The label does not publish how much licorice a serving carries or how much glycyrrhizin that licorice holds, so a reader cannot weigh the size of it. Licorice heads the declared order, which puts its ceiling at the whole 82 mg, and a ceiling that large rules out nothing.
Two conversations
Vitamin E and biotin, both worth raising
Vitamin E and blood thinners
NIH: “Taking large doses with anticoagulant or antiplatelet medications, such as warfarin (Coumadin), can increase the risk of bleeding, especially in conjunction with low vitamin K intake.” It also records that vitamin E “can inhibit platelet aggregation and antagonize vitamin K-dependent clotting factors”
Biotin and laboratory tests
NIH: “Supplementing with biotin beyond recommended intakes can cause clinically significant falsely high or falsely low laboratory test results” And: “FDA advises health care providers to ask their patients about any supplements they may be taking that contain biotin and to consider biotin interference as a possible source of error if laboratory test results do not match the clinical presentation of the patient.” The sizes belong in the same card as the finding: the amounts NIH reports are 10 to 300 mg a day, a single 10 mg dose moved a thyroid test, and 10 mg is 10,000 mcg. This label carries 315 mcg, about a thirty-second of the smallest of them.
Neither of those is a reason not to buy it and neither is presented as one. The vitamin E figure is 16 mg against a Daily Value of 15 mg and an upper limit of 1,000 mg, so the amount is not the issue; the interaction is, and it belongs in a sentence to a prescriber. The biotin figure is the largest multiple on the label and the smallest practical problem, which is an unusual combination and the reason it is drawn rather than described.
View as a table
| What | In micrograms | Where it comes from |
|---|---|---|
| The Daily Value | 30 mcg | NIH: 30 mcg for adults and children 4+ |
| This label, per serving | 315 mcg | printed on the panel as 1050% of it |
| One dose that moved a thyroid test | 10,000 mcg | NIH: a single 10 mg dose, inside 24 hours |
| The case reports | 10,000 to 300,000 mcg | NIH: patients taking 10 to 300 mg a day |
The figure above is the whole of the biotin argument in one picture. 315 mcg is ten and a half times the Daily Value, which is the eye-catching half. It is also roughly a thirty-second of the smallest dose NIH names in a case report, which is the half a scare story leaves out. NIH is also clear that “The FNB was unable to establish ULs for biotin because there is no evidence in humans that biotin is toxic at high intakes.” There is no upper limit for biotin because there is no evidence it is toxic at high intakes; the interference question is about measurement, not about harm from the vitamin.
The three upper limits
Zinc at 8 mg, magnesium at 125 mg, manganese at 1 mg
| Mineral | On this label | NIH upper limit | Share of the limit |
|---|---|---|---|
| Zinc | 8 mg | 40 mg a day | one fifth |
| Magnesium | 125 mg | 350 mg a day, supplemental | just over a third |
| Manganese | 1 mg | 11 mg a day | under a tenth |
Both minerals sit comfortably under the limits NIH publishes, and saying so is as much a part of this page as the warning at the top of it. Zinc becomes a problem in quantity: NIH records that “If used for weeks, doses of 50 mg zinc or more can interfere with copper absorption (which can cause low copper status), reduce immune function, and lower HDL cholesterol levels.” This label carries 8 mg, a fifth of the 40 mg upper limit. Magnesium in excess is usually a digestive matter rather than a systemic one, and NIH notes that “high doses of magnesium from dietary supplements or medications often result in diarrhea that can be accompanied by nausea and abdominal cramping” The supplemental upper limit is 350 mg and this label carries 125 mg. Neither figure is close to its ceiling and neither needs managing. The manganese is the third: 1 mg against an 11 mg upper limit, under a tenth of it.
What cannot be judged at all
The 12 members of the 82 mg blend have no published amounts. Anything dose-dependent about any of them — and the licorice at the top of the list is the clearest example — cannot be weighed from this bottle. The ordering rule gives a ceiling for each position, from the whole 82 mg at the top down to 6.9 mg at the bottom, and a ceiling is not a dose. It cannot tell you that an amount is small; it can only tell you that it is not larger than a number. Where a caution depends on how much you took, this label does not let you answer that, and no page on this site is going to pretend otherwise.
The printed caution
The rest of what the label says
Caution, as printed: Do not exceed recommended dose. Pregnant or nursing mothers, children under the age of 18 and individuals with a known medical condition should consult a physician before using this or any dietary supplement.
Also printed: Do not use if safety seal is damaged or missing.
Three more groups are named there, on top of the four in the warning. Add the vitamin E line for anyone on an anticoagulant and the corticosteroid line for anyone on steroids, and the list of people who should have a short conversation before starting is longer than the front of the bottle suggests. who it is for turns the same material into questions you can answer one at a time.
If something does happen
Stop taking it and speak to a clinician. This site holds stock and publishes the label; it does not give medical advice and cannot assess a symptom. The order desk on +1 (282) 450-4273 handles orders, tracking and refunds, and the 60-day window is reachable there. Anything about your body belongs with whoever manages your care.
