Xylitol toxic to dogs, stevia Reb A and licorice in Olivaro: what to know
Olivaro's other ingredients include xylitol, which FDA says is toxic to dogs, with a drop in blood sugar possible within 10 to 60 minutes, and stevia extract (Reb A). The blend adds monoammonium glycyrrhizinate, a licorice-derived compound. Glycyrrhizin can raise blood pressure and lower potassium. Keep the bottle away from pets.

On the label
What are Olivaro's other ingredients?
The label lists Glycerin, Water, Organic Lemon Extract, Stevia Extract 97% (Reb A), Xylitol, Sodium Benzoate, Potassium Sorbate, Citric Acid and “Natural Flavors” (Olivaro label).
These sit outside the 200 mg blend, and the label prints no amount for any of them. Two are sweeteners, xylitol and stevia. A third item, Monoammonium Glycyrrhizinate, is inside the blend, as the 18th of 22 names, also with no amount. The front says “Clean Ingredients*”. The label gives that phrase no definition, and no test report is on file.
| Name on the label | Xylitol, Stevia Extract 97% (Reb A) and Monoammonium Glycyrrhizinate |
|---|---|
| What it is | Two sweeteners in the other ingredients (xylitol, stevia) and a licorice-derived compound in the blend (monoammonium glycyrrhizinate) |
| What it is sold for | Sweeteners and a licorice compound |
| Amount on the label | xylitol and stevia: other ingredients; glycyrrhizinate: blend |
| Amount used in research | FDA on xylitol and dogs; a stevia meta-analysis; a review of licorice and blood pressure |
| What the studies found | FDA says xylitol can cause a rapid, profound drop in a dog's blood sugar within 10 to 60 minutes and lists dietary supplements among possible sources, so keep this bottle away from pets. A stevia meta-analysis of 26 studies found a low-certainty glucose fall only at 3,342 mg a day or more. A review says glycyrrhizin, the main compound in licorice, blocks an enzyme and can cause high sodium, low potassium and higher blood pressure with continued excess intake, with meta-analyses showing systolic pressure up 5.45 mmHg. It does not discuss monoammonium glycyrrhizinate specifically, and the label gives no amount. |
| Main caution | Keep the bottle away from dogs and other pets and call a vet or animal poison control right away if a dog may have swallowed it. If you have high blood pressure, a heart condition or take medicines for them, ask a clinician about the glycyrrhizinate row. |
Pets
Is xylitol toxic to dogs?
Yes. FDA says xylitol can cause a rapid and profound drop in a dog's blood sugar, an effect that can occur within 10 to 60 minutes (FDA, Xylitol dangerous for dogs).
FDA lists dietary supplements among the possible sources, and says other serious effects may not appear for up to 12 to 24 hours. Signs include vomiting, decreased activity, weakness, staggering, collapse and seizures. The page gives no toxic dose, so we cannot say how much Olivaro would matter, and we will not guess.
Call a veterinarian, an emergency clinic or animal poison control right away. Do not wait for signs. Store the bottle where pets and children cannot reach it, as the label says to keep it out of reach of children.
We found no source on xylitol's effects on people's stomachs, so we make no claim about them.
Stevia
What does stevia Reb A do to blood sugar in studies?
In a 2024 meta-analysis of 26 studies, stevia was followed by a low-certainty fall in glucose only at 3,342 mg a day or more, with no effect on insulin or HbA1c (Zare 2024, stevia glucose meta).
The label lists Stevia Extract 97% (Reb A) with no amount. The label gives no reason for it. No trial tested Olivaro, and we found no source on Reb A safety limits, so we say nothing about them. The chart below sets that 3,342 mg beside the 200 mg blend, which does not hold the stevia, and shows how far apart the numbers sit.
- Chromium (mcg, not mg)0.7 mcg on the label
Reference level: the adequate intake for men is 35 mcg a day (NIH); the label's chromium is 0.7 mcg, 2% of the Daily Value; not a study dose. A reference level, not a study dose: the label is 2% of the level. (NIH ODS, Chromium)
- Gymnema (at most 200 mg, the whole blend)at most 200 mg: the whole blend
Reference: LiverTox gives 400 mg three times daily (1,200 mg) as the typical dose; the label prints no gymnema amount, and 200 mg is the whole 22-ingredient blend. A reference level, not a study dose. The label prints no amount for this ingredient. (LiverTox, Gymnema)
- Caffeine (reference level)at most 200 mg: the whole blend
Reference level: 400 mg a day is FDA's level for most healthy adults; the label states no caffeine amount (guarana and green tea are in the 200 mg blend). A reference level, not a study dose. The label prints no amount for this ingredient. (FDA, Spilling the Beans caffeine) (Schimpl 2013, guarana review)
- Stevia (study threshold)at most 200 mg: the whole blend
Study: a meta-analysis found a low-certainty glucose fall only at 3,342 mg a day or more; the label prints no stevia amount. Studies used about 17 times the 200 mg blend ceiling. (Zare 2024, stevia glucose meta)
- Any other blend ingredientat most 200 mg: the whole blend
The label prints no amount for the other 18 ingredients; 200 mg is the whole blend. We found no trial at the unstated amount. No human trial range found. (21 CFR 101.36(c), proprietary blends) (Saldanha 2023, proprietary blends perspectives)
Log scale: each gridline is ten times the one before. Chromium is in micrograms (mcg), the other rows in milligrams (mg). Blend rows have no printed amount, so 200 mg, the whole blend, is shown as the most any one could hold. A bar being far away does not mean the product is unsafe or useless; it means the study results cannot be borrowed for it, because none tested Olivaro or this 22-ingredient blend.
Licorice
Can licorice raise blood pressure and lower potassium?
Yes, with continued excess intake. A review says glycyrrhizin, licorice's main compound, blocks an enzyme called 11-beta-HSD2 and can cause high sodium, low potassium and a larger fluid volume (Deutch 2019, licorice and blood pressure).
The review cites two meta-analyses, of 18 and 26 studies, in which licorice raised systolic blood pressure by 5.45 mmHg. The abstract gives no safe amount, and it does not discuss monoammonium glycyrrhizinate specifically. So we cannot say what the label's row does. It prints no amount, and the most it could hold is the whole 200 mg blend.
We found no source with consumer numbers for amount, duration or age, so we give none. Anyone with high blood pressure, a heart condition or a rhythm problem, or who takes medicine for them, should ask a clinician or pharmacist about this row first. Chest pain, fainting or trouble breathing: call 911.

Who should ask a clinician before using Olivaro?
Anyone with high blood pressure, heart disease or a known medical condition should ask first, and so should anyone on diabetes medicine or insulin.
Keep taking prescribed medicine exactly as directed, and never stop or change it because of a supplement. The label tells pregnant or nursing mothers and children under 18 to consult a physician. LiverTox links gymnema and green tea extract to rare liver injury reports, which is another reason to ask about gymnema. NCCIH finds no reliable evidence that any herbal supplement controls diabetes (NCCIH, Diabetes and dietary supplements).
- Bring the label and list every medicine and supplement you take.
- Mention the licorice-derived row if you take blood pressure medicine.
- Say that the bottle contains xylitol if you share your home with a dog.

FAQ
Sweeteners and licorice questions
Is xylitol in Olivaro?
Yes. Xylitol is listed among the other ingredients, with no amount printed. FDA says xylitol is dangerous for dogs, so keep the bottle away from pets and call a veterinarian or animal poison control if a dog may have swallowed some.
How fast does xylitol affect a dog?
FDA says a dog's blood sugar can drop within 10 to 60 minutes, and other serious effects may take up to 12 to 24 hours. Do not wait for signs. Call a veterinarian, emergency clinic or animal poison control right away.
What is stevia Reb A?
Reb A is the name for a compound from the stevia plant, and the label lists Stevia Extract 97% (Reb A) among the other ingredients with no amount. A 26-study meta-analysis saw a low-certainty glucose fall only at 3,342 mg a day or more.
What is monoammonium glycyrrhizinate?
It is a licorice-derived compound, listed in the blend with no amount. A review says glycyrrhizin, licorice's main compound, can raise blood pressure and lower potassium with continued excess intake. It does not discuss this specific compound.
Does Olivaro contain licorice root?
The label does not list licorice root. It lists Monoammonium Glycyrrhizinate, a licorice-derived compound, in the blend, and prints no amount.
Should I worry about licorice and blood pressure with Olivaro?
Ask a clinician or pharmacist if you have high blood pressure or take blood pressure medicine. We cannot say what the unprinted amount does, and the review we read did not study this specific compound.
