HelloPharmacist Scorecard of Gut Buddies Plus FOS by Tishcon Corp.

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 11, 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 1 of its 6 active ingredients.
  • “Blend” is a proprietary blend — the label gives one combined amount (10,000,000,000 CFU) without saying how much of each component you get.

Gut Buddies Plus FOS contains 6 active ingredients: a proprietary blend that includes FOS (a type of dietary fiber), plus five strains of live probiotic bacteria — Bl-04 Bifidobacterium lactis, La-14 Lactobacillus acidophilus, Ls-33 Lactobacillus salivarius, Lp-115 Lactobacillus plantarum, and Lc-11 Lactobacillus casei. The capsules also contain inactive ingredients (hypromellose, vegetable magnesium stearate, silicon dioxide, and purified water) that help hold the formula together.

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: broad spectrum probiotic digestive health support.
  • We looked for evidence on: Antibiotic-associated diarrhea, Bacterial vaginosis, Clostridioides difficile infection, Colic, Constipation, Irritable bowel syndrome (IBS) — and 4 related terms.
  • The strongest evidence on file: Lactobacillus Acidophilus is rated "Possibly Effective" for Antibiotic-associated diarrhea (Natural Medicines).
  • Also on file: Lactobacillus Acidophilus is rated "Possibly Effective" for Bacterial vaginosis, Irritable bowel syndrome (IBS).
  • Also on file: Lactobacillus Acidophilus is rated "Insufficient Reliable Evidence To Rate" for Constipation, Lactose intolerance, Necrotizing enterocolitis (NEC), Postoperative infection.

L. acidophilus shows possibly effective evidence for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis. It's rated possibly ineffective for atopic disease, and we don't have enough reliable data to rate it for acute respiratory distress syndrome (ARDS).

We have no established effectiveness data in our records for the other four bacterial strains in this product or for FOS itself.

The evidence, ingredient by ingredient Lactobacillus Acidophilus

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.

L. acidophilus is generally well tolerated in healthy adults and children. In clinical trials, some people experienced mild gastrointestinal side effects — epigastric discomfort, abdominal pain, indigestion, gas, bloating, diarrhea, vomiting, or burping — though these are uncommon.

Because L. acidophilus preparations contain live organisms, there's a theoretical concern that they might cause infection in certain patients, though most reported cases appear to be due to bacteria moving from other parts of the body where they naturally live. The data are limited, so ask your healthcare provider before use.

Side effects, ingredient by ingredient Lactobacillus Acidophilus

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 — Lactobacillus Acidophilus.
  • 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 antibiotic drugs, check with your pharmacist — L. acidophilus in this product may lose effectiveness if you take them at the same time. We could not check interactions for the other bacterial strains and FOS.

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 IBS, antibiotic-related diarrhea, and a few other digestive concerns, based on the L. acidophilus it contains. If you take antibiotics, space them apart from this probiotic to protect its effectiveness.

Talk with your pharmacist before starting, especially if you have a weakened immune system or are taking medications.

Antibiotic Drugs

Theoretically, taking Lactobacillus acidophilus with antibiotic drugs might decrease the effectiveness of L. acidophilus.
L. acidophilus 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 L. acidophilus preparations by at least two hours.

Gut Buddies Plus FOS by Tishcon Corp.: Common Questions

Does Gut Buddies Plus FOS by Tishcon Corp. interact with any medications?
Yes. Based on its ingredients, Gut Buddies Plus FOS 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?
Gut Buddies Plus FOS contains 6 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 is FOS and what does it do?
FOS (fructooligosaccharides) is a type of dietary fiber included in this product. We don't have effectiveness data on file for FOS alone, but it's often used in probiotic formulas to support digestive health.
Can I take this with antibiotics?
You can, but timing matters. Antibiotics kill bacteria — including the live organisms in this probiotic — so they work best when spaced apart. Ask your pharmacist how many hours to wait between them.
Does L. acidophilus really help with IBS and diarrhea?
L. acidophilus is rated possibly effective for both irritable bowel syndrome and antibiotic-associated diarrhea, meaning the evidence supports it but isn't conclusive. Individual results vary.
What side effects might I experience?
Most people tolerate it well, but some experience mild gas, bloating, abdominal discomfort, or changes in bowel movements — these are uncommon and often temporary. If you develop a rash or other unusual symptoms, stop and tell your doctor.
Is this safe if I have a weakened immune system?
L. acidophilus is generally well tolerated, but because it contains live organisms, there's a theoretical risk in people with severely compromised immunity. Talk with your doctor before starting.
Can I take this while pregnant or nursing?
We don't have safety data on file for L. acidophilus — or the other ingredients in this product — during pregnancy or breastfeeding. Please ask your doctor or pharmacist for personalized advice.
