Licorice Root in Black Sugar Protect: The Ingredient to Check First
Licorice root is one of six ingredients the brand names for Black Sugar Protect, but the amount is not disclosed. No study has set a blood sugar dose for it. Its compound glycyrrhizin can raise blood pressure and lower potassium, more so with larger amounts or long use. Ask first if you have high blood pressure or heart or kidney disease.

On the list
Is there licorice root in Black Sugar Protect?
Yes. Licorice root is the first of the six ingredients on the brand's ingredient graphic. The amount is not disclosed, and neither is the form, such as a powder or an extract.
The sales page text never names it. It appears only as the words "LICORICE ROOT" over a stock photo of licorice sticks (Black Sugar Protect sales page). A paid press release from the brand also lists it, again with no amount (Newswire, sponsored).
The brand does not say why licorice is in a blood sugar formula. That matters, because licorice has a clear safety signal and no blood sugar case. The rest of the formula is covered on the ingredients page.

How it acts
Can licorice root raise blood pressure?
Yes. The main compound in licorice root, glycyrrhizin, can cause high blood pressure together with low potassium. Doctors call this hypokalemic hypertension, and it is the most common side effect of licorice (MSK, Licorice).
It is not only a problem with huge amounts. Memorial Sloan Kettering notes that eating even moderate doses over time has been linked to both effects. Case reports describe irregular heart rhythms and cardiac arrest after heavy use (MSK, Licorice).
NCCIH says even small amounts of glycyrrhizin have been linked to severe effects in people with high blood pressure. People with heart or kidney conditions, or a high salt intake, may react to smaller amounts too (NCCIH, Licorice).
That is why licorice deserves a careful look in any product meant for people watching their blood sugar.
Evidence
Does licorice root help blood sugar?
No study we could find supports it. None of our sources sets a blood sugar dose for licorice root, and the brand cites no study for including it (MSK, Licorice) (Black Sugar Protect sales page).
The American Diabetes Association's 2026 Standards say herb and spice supplements are not recommended for blood sugar benefit (ADA, Standards of Care 2026). So licorice adds a known risk without a shown benefit for blood sugar. In fairness, the amount may be small. Nobody can judge that until the label is published.
Who should ask first
Who should avoid licorice root?
People with blood pressure, heart or kidney problems, and anyone pregnant, should talk to a clinician before taking a product with licorice. The table sums up why.
| If you... | Why it matters | Source |
|---|---|---|
| Have high blood pressure | Even small amounts have been linked to severe effects | (NCCIH, Licorice) |
| Take a water pill (diuretic) | Higher risk of low potassium | (MSK, Licorice) |
| Take digoxin | May raise the risk of digoxin toxicity | (MSK, Licorice) |
| Take blood pressure medicine | May interfere with how it works | (MSK, Licorice) |
| Have heart or kidney disease, or eat a lot of salt | Smaller amounts may cause effects | (NCCIH, Licorice) |
| Are pregnant | Large amounts by mouth are unsafe | (NCCIH, Licorice) |
