HelloPharmacist Scorecard of Chewable Soluble Fiber With Probiotics by Mason Natural

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

Generated from HelloPharmacist’s pharmacist-curated databases and editorial rules · Last generated Jul 16, 2026

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 product contains 2 active ingredients: Bacillus coagulans, a live probiotic organism, and Fibersol 2, a soluble fiber. The inactive ingredients are stearic acid, magnesium stearate, silica, natural flavors, and natural fruit juices.

Does it work?

Moderate 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

This product doesn't appear to be marketed for a specific use, so we graded Bacillus Coagulans's overall clinical evidence instead.

Moderate

Some clinical evidence supports Bacillus Coagulans for:

Why this rating?
  • The label markets general wellness (“digestive health”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Constipation — rated "Possibly Effective" (Natural Medicines).
  • On file: Irritable bowel syndrome (IBS) — rated "Possibly Effective" (Natural Medicines).

Bacillus coagulans is possibly effective for constipation and irritable bowel syndrome (IBS). For other uses — antibiotic-associated diarrhea, athletic performance, cancer prevention, and nonalcoholic fatty liver disease — the evidence isn't established in the data we hold.

We couldn't check effectiveness data for Fibersol 2.

The evidence, ingredient by ingredient Bacillus Coagulans

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 1 of the 1 matched ingredient.
  • Pregnancy & breastfeeding safety ratings cover 1 of 1.
  • General safety write-ups exist for 1 of 1.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Bacillus coagulans is generally well tolerated in healthy adults, though evidence and product quality can vary from brand to brand. Safety data is limited, so talk to your doctor or pharmacist before using, especially if you have a weakened immune system, are severely ill, or have a central catheter — live probiotics have rarely caused serious bloodstream infections (bacteremia) or sepsis in these high-risk groups.

We have no reliable pregnancy or breastfeeding safety data on file for either ingredient, so discuss this product with your doctor or pharmacist if you're pregnant or nursing.

Side effects, ingredient by ingredient Bacillus Coagulans

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 1 matched ingredient can interact with medications — Bacillus Coagulans.
  • The most serious interaction on file is rated Moderate.
  • For scale: 182 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.

If you take antibiotics, you'll need to space them out from this probiotic — talk to your doctor or pharmacist about timing. The product contains live organisms, so anyone with a severely weakened immune system, central venous catheter, or severe illness should check with their healthcare provider first.

Check your own medication Run your meds through the checker above

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help with constipation or IBS symptoms if Bacillus coagulans works for you, but you'll need to time it carefully around any antibiotics. If you're generally healthy with a normal immune system, it's generally well tolerated, but if you're immunocompromised or seriously ill, check with your doctor first.

Talk it over with your own doctor or pharmacist before starting.

Antibiotic Drugs

Theoretically, taking antibiotics with Bacillus coagulans might decrease the effectiveness of B. coagulans.
B. coagulans preparations usually contain live and active organisms. Therefore, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and B. coagulans preparations by at least two hours.

Chewable Soluble Fiber With Probiotics by Mason Natural: Common Questions

Does Chewable Soluble Fiber With Probiotics by Mason Natural interact with any medications?
Yes. Based on its ingredients, Chewable Soluble Fiber With Probiotics has a known interaction with 182 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Chewable Soluble Fiber With Probiotics contains 2 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 does Bacillus coagulans do?
It's a live probiotic that may help with constipation and irritable bowel syndrome. For other conditions like antibiotic-associated diarrhea or athletic performance, we don't have enough solid evidence to say whether it works.
Will this work if I'm on antibiotics?
Antibiotics can kill off the live organisms in this probiotic, making it less effective. You'll need to take them at different times — ask your doctor or pharmacist for the right schedule.
Is this safe if I'm pregnant or breastfeeding?
We don't have enough safety data to know either way. Talk with your doctor or pharmacist about whether this product is right for you during pregnancy or nursing.
What about side effects?
It's generally well tolerated in healthy people, though product quality varies. Live probiotics are very rarely linked to serious infections in people with weakened immune systems or critical illness — if that's your situation, check with your doctor first.
Why couldn't you check the fiber ingredient?
We don't hold interaction data for Fibersol 2 on file, so we can't tell you what it might interact with. You can still run your specific medications through our search tool to be thorough.
