HelloPharmacist Scorecard of Fiber Gummy Rings Berry Melon by OLLY

Our pharmacy team’s full take, with four database checks built into the cards below — a summary of what is known, not a grade of the product itself.

From our pharmacy team — supplement deep dive

What’s inside

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

This gummy contains one active ingredient: fructooligosaccharides (FOS), a type of fiber derived from plants. FOS is meant to support digestive health.

The gummies also contain inactive ingredients — water, sugar, gelatin, glucose syrup, pectin, and various acids and flavorings — that give them their texture, taste, and shelf life.

Does it work?

Strong evidence
Evidence for Intended Use · database check
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
Strong

Clinical evidence supports at least one of this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Supports bowel and digestive health.
  • We looked for evidence on: Constipation, Diarrhea, Digestive regularity, Gut microbiota balance.
  • The strongest evidence on file: Black Psyllium is rated "Effective" for Constipation (Natural Medicines).
  • Also on file: Black Psyllium is rated "Insufficient Reliable Evidence To Rate" for Diarrhea.
  • Also on file: Fructo-oligosaccharides (fos) is rated "Insufficient Reliable Evidence To Rate" for Constipation, Travelers' diarrhea.

The evidence isn't established in the data we hold. FOS has been studied for constipation, osteoporosis, diabetes, travelers' diarrhea, and high cholesterol, but the research so far is insufficient to rate whether it actually works for any of these purposes.

If you're thinking about this product for a specific reason, it's worth talking through with your doctor about what the science does and doesn't support.

The evidence, ingredient by ingredient Black Psyllium Fructo-oligosaccharides (fos)

How safe is it?

Well-documented data
Safety Information · database check
Well characterized

Adverse-effect, pregnancy, and general safety data are on file for most of these ingredients.

Why this rating?
  • We hold adverse-effect (side-effect) data for 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

FOS is generally well tolerated in food amounts, but at supplement-level doses the safety data is limited — so check with your doctor before starting, especially if you're using it regularly. The most common side effects are gas, bloating, abdominal pain, and flatulence.

Interestingly, a review of clinical studies found that FOS doses between 2.5 and 15 grams daily for up to 8 weeks did not increase these symptoms more than placebo, though individual experience can vary — starting at a lower dose may help you find what your stomach handles best.

Meds to double-check

Moderate interaction found
Known Interaction Concern · database check
Moderate identified

The most serious documented interaction for these ingredients is Moderate. Check your medications for a personalized result.

Why this rating?
  • 1 of the 2 matched ingredients can interact with medications — Black Psyllium.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: heart-rhythm medications; lithium.
  • For scale: 2,026 individual medications appear in the full list. A big number alone doesn't make a product dangerous — what matters is whether YOUR medication is on it, so run yours through the interaction checker on this page.

No interactions are documented for the ingredients we could check. You're still welcome to run your specific medications through the search tool on this page, or mention this product to your own doctor or pharmacist before starting.

Ingredients driving the most interactions

Each ingredient & the kinds of drugs it affects

For each ingredient in Fiber Gummy Rings Berry Melon with known interactions, here are the types of medications it can affect. Open any type for the detail — or search your exact drug in the checker above.

Dietary Fiber7 drug types · 2,025 drugs

Carbamazepine (Tegretol)

Theoretically, black psyllium might reduce the effects of carbamazepine and increase the risk for convulsions.
Theoretically, black psyllium might reduce carbamazepine absorption. A preliminary study using blond psyllium reported decreased carbamazepine bioavailability due to binding of the drug to psyllium, as well as reduction of available fluid in the gut for dissolution of the drug. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Lithium

Theoretically, taking black psyllium at the same time as lithium might reduce lithium absorption.
The fiber in black psyllium might reduce lithium absorption and plasma levels. Some case reports describe a reduction in plasma lithium levels with concomitant administration of blond psyllium. This was reversed when psyllium was stopped. This interaction may also occur with black psyllium.

Likelihood Probable Evidence D
Metformin (Glucophage)

Theoretically, black psyllium might increase the therapeutic and adverse effects of metformin.
Animal research shows that concurrent consumption of blond psyllium with metformin slows and increases the absorption of metformin. This interaction may also occur with black psyllium. To avoid changes in absorption, take psyllium 30-60 minutes after metformin.

Likelihood Possible Evidence D
Olanzapine (Zyprexa)

Theoretically, taking black psyllium at the same time as olanzapine might reduce olanzapine absorption.
The fiber in black psyllium might decrease the absorption of olanzapine. A single case report describes a reduction in the effectiveness of olanzapine when it was concomitantly administered with an unspecified type of psyllium 3 grams orally twice daily. This effect was reversed when psyllium was stopped.

Likelihood Possible Evidence D
Digoxin (Lanoxin)

Theoretically, taking black psyllium at the same time as digoxin might reduce digoxin absorption and decrease digoxin levels.
Psyllium might bind digoxin in the gut. However, some clinical evidence suggests that psyllium does not impact digoxin absorption.

Likelihood Unlikely Evidence B
Ethinyl Estradiol

Theoretically, taking black psyllium at the same time as ethinyl estradiol might alter levels of estradiol.
Concurrent use of blond psyllium with ethinyl estradiol results in a slight increase in the extent of ethinyl estradiol absorption and a slower rate of absorption. This is unlikely to be clinically significant.

Likelihood Unlikely Evidence D
Oral Drugs

Theoretically, psyllium might increase, decrease, or have no effect on the absorption of oral drugs.
Psyllium seems to have variable effects on drug absorption. To avoid changes in absorption, take psyllium 30-60 minutes after oral medications. Animal research shows that blond psyllium delays and increases the absorption of metformin and ethinyl estradiol. Case reports and animal research suggest that blond psyllium might reduce absorption of lithium, digoxin, olanzapine, and carbamazepine. Finally, some pharmacokinetic studies show that psyllium does not affect the absorption of levothyroxine or warfarin. Although many of these studies evaluated blond psyllium, the fiber content in black psyllium may have similar effects.

Fiber Gummy Rings Berry Melon by OLLY: Common Questions

Does Fiber Gummy Rings Berry Melon by OLLY interact with any medications?
Yes. Based on its ingredients, Fiber Gummy Rings Berry Melon has a known interaction with 2,025 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Fiber Gummy Rings Berry Melon contains 3 active ingredients, and an interaction can come from any of them. We check every ingredient, combine the results into one list per medication, and show which ingredient and mechanism is responsible.
Where does this information come from?
The product label data comes from the NIH Dietary Supplement Label Database (DSLD); the interaction data is built on the Natural Medicines database and reviewed by HelloPharmacist pharmacists.
What exactly is FOS?
FOS stands for fructooligosaccharides — a type of carbohydrate fiber that comes from plants. It's meant to support digestive health, though the evidence for what it actually does isn't well established yet.
Will this give me gas or bloating?
Gas, bloating, and abdominal discomfort are the most common side effects people report with FOS, especially at higher doses. That said, clinical studies found these symptoms didn't happen more often than placebo in doses up to 15 grams daily. Your experience might differ — if you're new to it, start with a smaller amount and see how your stomach responds.
Is it safe to take while breastfeeding?
The product facts don't include safety data for pregnancy or breastfeeding. Talk with your doctor or pharmacist about whether it's okay for you personally.
Does this actually help with constipation, diabetes, or cholesterol?
FOS has been studied for all three, but the evidence so far is too weak to say whether it works. If you're considering it for one of these reasons, check with your doctor about what's actually proven to help with your situation.
What are the inactive ingredients in this gummy?
The gummies contain water, sugar, gelatin, glucose syrup, pectin, lactic acid, citric acid, natural flavors, tartaric acid, black carrot, and copper chlorophyllin — all there to give the gummy its texture, taste, and shelf life.
