HelloPharmacist Scorecard of Fast Acting Enzymes + Daily Probiotic by Schiff Digestive Advantage

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 30, 2026

What’s inside

Low disclosure
Ingredient Transparency · database check
Low

Most active ingredients don't disclose an individual amount — you can't tell how much of each you're getting.

Why this rating?
  • The label discloses an exact amount for 0 of its 5 active ingredients.

This product contains five active ingredients, each a digestive enzyme or probiotic. Bacillus coagulans GBI-30 6086 is a live probiotic organism that may support gut function.

Hemicellulase, alpha-galactosidase, cellulase, and invertase are digestive enzymes — proteins that break down different kinds of carbohydrates and fiber in food to make them easier for your body to absorb. The remaining ingredients are inactive — fillers and binders that give the capsule its form and stability.

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
Moderate

Some clinical evidence supports this product's ingredients for its stated purpose, but it isn't conclusive.

Why this rating?
  • The label markets this product for: digestive support and bloating relief.
  • We looked for evidence on: Constipation, Flatulence, Irritable bowel syndrome (IBS), Dyspepsia, Gas, Abdominal discomfort — and 1 related terms.
  • The strongest evidence on file: Bacillus Coagulans is rated "Possibly Effective" for Constipation (Natural Medicines).
  • Also on file: Bacillus Coagulans is rated "Possibly Effective" for Irritable bowel syndrome (IBS).
  • Also on file: Bacillus Coagulans is rated "Insufficient Reliable Evidence To Rate" for Dyspepsia, Flatulence.

Bacillus coagulans is possibly effective for constipation and for irritable bowel syndrome (IBS). For antibiotic-associated diarrhea, athletic performance, cancer, and nonalcoholic fatty liver disease, the evidence isn't strong enough to rate it one way or the other.

We don't hold effectiveness ratings for the enzymes (hemicellulase, alpha-galactosidase, cellulase, and invertase) in our data.

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 the quality and safety data for probiotic products vary. That said, there isn't enough reliable safety information overall, so talk to your doctor before starting.

There is a theoretical concern that live probiotic organisms could cause infection in people with severely weakened immune systems, central lines, or other serious illness — though this risk is very low in people with healthy, intact immune systems. The pregnancy and lactation safety data for Bacillus coagulans isn't on file for us; ask your doctor or pharmacist for personalized advice if you're pregnant or breastfeeding.

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.

Check with your doctor or pharmacist before combining this product with antibiotics. Antibiotics are the only drug type with documented interactions with Bacillus coagulans in our data.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This product may help with constipation or IBS symptoms through its probiotic. If you take antibiotics, time them separately from the probiotic so the antibiotic doesn't kill the live organisms.

Talk with your doctor or pharmacist before starting, especially if you have a weakened immune system or are pregnant or breastfeeding.

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.

Does Fast Acting Enzymes + Daily Probiotic by Schiff Digestive Advantage interact with any medications?
Yes. Based on its ingredients, Fast Acting Enzymes + Daily Probiotic 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?
Fast Acting Enzymes + Daily Probiotic contains 5 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.
Will this help my IBS?
Bacillus coagulans in this product is possibly effective for IBS. That means the evidence suggests it may help, but it's not guaranteed to work for everyone. Talk to your doctor if your symptoms don't improve or get worse.
Can I take this if I'm on an antibiotic?
You can, but don't take them at the same time. Antibiotics can kill the live organisms in the probiotic and make it less effective. Separate them by a few hours — ask your pharmacist for the best timing with your specific antibiotic.
What do the digestive enzymes in this do?
They break down carbohydrates and fiber in your food so your body can absorb them more easily. The four enzymes work together to handle different types of carbs and plant material.
Is this safe if I'm pregnant?
We don't have enough safety data for Bacillus coagulans in pregnancy. Talk to your doctor or pharmacist before taking it if you're pregnant or breastfeeding — they can give you personalized advice based on your situation.
Does this have fillers?
Yes, it contains several inactive ingredients like maltodextrin, microcrystalline cellulose, and magnesium stearate, which are standard binders and flow agents in capsules.
Is this safe for people with weakened immune systems?
Probiotic products that contain live organisms carry a very small theoretical risk in severely ill or immunocompromised people. If your immune system is weak or you have a central line, check with your doctor before using this.
