Burn Gummy Side Effects and Who Should Be Careful
Most Burn Gummy side effects are mild: stomach upset, gas or loose stools.
Berberine may affect metformin, cyclosporine and other drugs, and chromium may lower blood sugar with diabetes medication and reduce levothyroxine absorption. It is not for pregnancy, breastfeeding or under-18s.
Use the fit check before ordering.
What are the most common Burn Gummy side effects?
A quick map first. Each ingredient gets its own section below.
The most likely Burn Gummy side effects are mild stomach problems. Berberine can upset the stomach, and the sweeteners maltitol and xylitol can cause gas or loose stools. The bigger risks are drug interactions, which matter most if you take diabetes, thyroid or transplant medicines.
The table sorts each effect by the ingredient behind it. Most people who take one gummy a day will notice nothing at all, since the doses are small. Small does not mean zero, so read the rows that apply to you.
Possible Burn Gummy side effects and interactions, by ingredient
| Possible effect | Linked ingredient | What to do |
|---|---|---|
| Upset stomach, cramps, constipation or diarrhea | Berberine HCl (40 mg) | Take it with food. Stop if it lasts more than a few days. |
| Gas, bloating or loose stools | Maltitol and xylitol | Cut back on other sugar-free foods. Stop if it continues. |
| Low blood sugar (shaky, sweaty, dizzy) | Berberine and chromium, with diabetes medicines | Eat some sugar, check your level, call your doctor. |
| Changed drug levels | Berberine | Ask a pharmacist before you start if you take any medicine. |
| Less thyroid medicine absorbed | Chromium (25 mcg) | Space the two apart. Ask your pharmacist how. |
| Liver stress (rare) | Coumarin, if cassia cinnamon is used | Skip it if you have liver disease, unless a doctor agrees. |
| Reaction to a dye | FD&C Red 40 | Stop and seek care for hives, swelling or trouble breathing. |
Berberine in Burn Gummy: stomach effects and drug interactions
The ingredient with the most side-effect data. Most of it comes from doses 12 to 38 times higher than one gummy.

Berberine's main side effects are in the gut: nausea, cramps, gas, constipation and diarrhea (NCCIH, Berberine and weight loss). Trials that used 500–1,500 mg a day reported mostly these GI effects (Dong et al., 2012). One gummy has 40 mg, so stomach effects should be milder, but some people are sensitive. The dose comparison is on the Burn Gummy ingredients page.
Drug interactions are the more serious issue. Goldenseal, a plant rich in berberine, changed how the body handled metformin and many other drugs (NCCIH, Goldenseal). Berberine slows some liver enzymes, called CYP enzymes, that clear drugs from the body. When those enzymes slow down, drug levels in the blood can rise.
- Metformin and other diabetes medicines: blood sugar may drop too low
- Cyclosporine: a transplant drug whose blood level can rise with berberine
- Drugs cleared by CYP enzymes: many heart, cholesterol, seizure, mood and blood-thinning medicines
- Any prescription taken daily: ask a pharmacist to check it against berberine
Is Burn Gummy safe during pregnancy or breastfeeding?
No. Burn Gummy is not for pregnancy or breastfeeding. Berberine may be unsafe during both, and it can pass to a baby through breast milk (NCCIH, Berberine and weight loss). Newborns may be at risk of a serious form of jaundice. The same advice applies to goldenseal and other berberine plants (NCCIH, Goldenseal).
If you find out you are pregnant while taking Burn Gummy, stop and tell your doctor. One gummy is a small dose, but there is no reason to keep taking it.
Chromium in Burn Gummy: diabetes medicines and thyroid medicine
Each gummy has 25 mcg of chromium, 71% of the Daily Value. That is a normal food-level amount. Two interactions still matter (NIH ODS, Chromium). Our chromium picolinate article covers the mineral in more depth.
Diabetes medicines and low blood sugar
Chromium, and berberine too, may add to the effect of insulin and diabetes pills. Together they could push blood sugar too low. Watch for these signs, especially in the first weeks:
- Shaky hands
- Sweating
- Fast heartbeat
- Sudden hunger
- Dizziness
- Confusion
- Headache
If they appear, eat or drink some fast sugar and check your level if you can. Then call your doctor before your next gummy.
Levothyroxine and thyroid medicine
Chromium may lower the amount of levothyroxine your body absorbs. Taking them at the same time could make your thyroid dose less effective. Ask your pharmacist how many hours apart to take them. Many people take thyroid pills first thing, so a gummy later in the morning may need a set gap.
Cinnamon in Burn Gummy: coumarin and the liver
Cinnamon is safe in normal food amounts for most people. The concern is coumarin, a natural compound found in high levels in cassia cinnamon. Coumarin has been linked to liver problems in sensitive people (NCCIH, Cinnamon). Ceylon cinnamon has far less.
The Burn Gummy label says “cinnamon bark extract, 28 mg” and does not name the species. Extracts can also hold more or less coumarin than the raw bark. We cannot tell you how much coumarin one gummy holds. At 28 mg of extract, the amount is likely small.
- Skip it if you have liver disease, unless your doctor agrees.
- Tell your doctor if you take other drugs that can affect the liver.
- Stop and seek care for yellow skin or eyes, dark urine or pain under the right ribs.
Sugar alcohols in Burn Gummy gummies: gas and loose stools

Burn Gummy is sweetened with maltitol and xylitol. These sugar alcohols are only partly absorbed. The rest reaches the colon, where bacteria ferment them and draw in water. The result can be gas, bloating and a laxative effect, and it grows with the dose (Lenhart & Chey, 2017).
One gummy has 1 g of total carbohydrate, and sugar alcohols count toward it. So each gummy holds well under a gram. On its own, that rarely causes trouble. Symptoms are more likely if you also eat sugar-free candy, gum, protein bars or drinks. More in our maltitol and xylitol article.
- People with IBS may react to small amounts.
- Take the gummy with food if your stomach is sensitive.
- Never take extra gummies. More sweetener means more gut effects.
Red 40, sweeteners and allergies in Burn Gummy
Other Burn Gummy ingredients that some people choose to avoid
| Ingredient | Why it is there | Who should take care |
|---|---|---|
| FD&C Red 40 | Color | People who avoid synthetic dyes, or who have reacted to dyes before |
| Acesulfame K | Sweetener | People who avoid artificial sweeteners |
| Stevia leaf extract | Sweetener | People sensitive to stevia or plants in the daisy family |
| Natural flavoring | Taste | People with food allergies: the source is not listed |
| Pectin, rice flour | Texture and coating | Rarely a problem; check if you have a rice allergy |
Red 40 is a common food dye approved for use in the United States. A small number of people react to dyes with hives or itching. Some parents avoid it for children, but Burn Gummy is for adults only. If you have food allergies, ask the order desk at +1 (855) 482-1597 about the flavoring source before you start. The full list is on the Burn Gummy Supplement Facts page.
Keep Burn Gummy away from dogs: xylitol is toxic to pets
Burn Gummy contains xylitol. In dogs, xylitol can cause a fast, dangerous drop in blood sugar and can damage the liver. A few gummies may be enough to harm a small dog. Signs can start within an hour: vomiting, weakness, wobbling or seizures.
- Store the bottle high up and closed, not in a handbag on the floor.
- Do not drop or share gummies around pets.
- If a dog eats any, call your vet or an animal poison control line right away. Do not wait for signs.
When to stop taking Burn Gummy and call a doctor
Most people will never need this list. Keep it anyway.
- Right away
Seek urgent care
Hives, swelling of the face or throat, trouble breathing, fainting, or confusion that could mean very low blood sugar.
- Same day
Stop and call your doctor
Shaky or sweaty spells, yellow skin or eyes, dark urine, or strong stomach pain.
- Within a few days
Stop and reassess
Diarrhea, cramps or bloating that last more than two or three days.
- Before you restart
Check your medicines
A new prescription, a changed dose, a pregnancy or planned surgery. Ask before taking another gummy.
Bring the bottle to any appointment so your doctor can read the label. If you stop inside 60 days of purchase, call +1 (855) 482-1597 about a refund. Day-to-day use is covered on the how to use Burn Gummy page.
Burn Gummy side effects questions
What are the most common Burn Gummy side effects?
The most likely are stomach upset from berberine and gas or loose stools from the sugar alcohols maltitol and xylitol. At one gummy a day, both are usually mild. Stop and ask a doctor if they last or get worse.
Can I take Burn Gummy with metformin?
Ask your doctor first. Berberine changes how the body handles metformin and many other drugs, and berberine and chromium can add to the blood sugar lowering effect of diabetes medicines. That raises the risk of low blood sugar.
Can I take Burn Gummy while pregnant or breastfeeding?
No. Berberine may be unsafe during pregnancy and breastfeeding, and it may harm a newborn. Burn Gummy is for healthy adults 18 and over only.
Does Burn Gummy affect thyroid medicine?
It can. Chromium may reduce how much levothyroxine your body absorbs. If you take thyroid medicine, ask your pharmacist how far apart to space the two.
Is Burn Gummy dangerous for dogs?
Yes. It contains xylitol, which is toxic to dogs even in small amounts. Keep the bottle out of reach, and call a vet right away if a dog eats any gummies.
Is the cinnamon in Burn Gummy bad for the liver?
The risk is linked to coumarin in cassia cinnamon, mostly at high intakes. The label does not say which cinnamon is used, and 28 mg is a small amount. People with liver disease should ask a doctor first.
Does Burn Gummy cause jitters or trouble sleeping?
It should not. The label lists no caffeine or other stimulant. If you feel shaky or sweaty, that can be a sign of low blood sugar, especially if you take diabetes medicine.
When should I stop taking Burn Gummy?
Stop if you have ongoing stomach pain, diarrhea, signs of low blood sugar, a rash or swelling, or yellow skin or eyes. Stop and call your doctor if you become pregnant or start a new medicine.
