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

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 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

This product contains one active ingredient: Lactobacillus acidophilus La-14, a live probiotic microorganism. The inactive ingredients are tapioca dextrose, organic bamboo extract, and organic rice extract blend, which serve as fillers and capsule material.

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 health and probiotic balance.
  • We looked for evidence on: Antibiotic-associated diarrhea, Bacterial vaginosis, Clostridioides difficile infection, Colic, Constipation, Inflammatory bowel disease (IBD) — 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, Inflammatory bowel disease (IBD), Lactose intolerance, Necrotizing enterocolitis (NEC).

The evidence supports that Lactobacillus acidophilus is possibly effective for irritable bowel syndrome (IBS), Helicobacter pylori (a stomach bacterium), antibiotic-associated diarrhea, and bacterial vaginosis. It's rated possibly ineffective for atopic disease (allergic conditions).

For acute respiratory distress syndrome, we don't have enough reliable evidence to say either way.

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.

Lactobacillus acidophilus is generally well tolerated in healthy adults and children. Because it contains live organisms, there's a theoretical concern it could cause infection in some patients — though most documented cases occurred in people with existing conditions that allowed bacteria to move into the bloodstream.

Gastrointestinal side effects like bloating, gas, stomach discomfort, and diarrhea are possible but uncommon when taking it with other probiotics. Skin rash and itching were reported in one trial, though it's unclear if the probiotic was responsible.

The data are limited, so talk with your doctor or pharmacist before starting, especially if you have a weakened immune system or serious illness.

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.

Separate antibiotic drugs by a few hours from this probiotic — taking them at the same time may reduce the probiotic's effectiveness.

The bottom line

Scorecard at a glanceFully disclosed formula with some supporting evidence for its stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This probiotic may help with IBS, antibiotic-associated diarrhea, and a few other conditions if the evidence bears out for you. If you're on antibiotics, space them a few hours apart from this supplement.

Our Terrific Tummy contains 1.5 billion active cultures to provide you with probiotics to help keep your flora happy. Ingredients facts Lactobacillus acidophilus is a species naturally found in the intestinal tract and a variety of fruits and vegetables. The strain in Terrific Tummy ferments various non-digestible carbohydrates to produce lactic acid. Lactic acid in the digestive system can reduce pH levels which creates a favorable environment for the absorption of minerals like Calcium and Magnesium.

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.

Terrific Tummy Probiotic by Sundown Organics: Common Questions

Does Terrific Tummy Probiotic by Sundown Organics interact with any medications?
Yes. Based on its ingredients, Terrific Tummy 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?
Terrific Tummy Probiotic contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
Can I take this while I'm on antibiotics?
You can take both, but not at the exact same time. Antibiotics can kill the live organisms in the probiotic, making it less effective. Space them a few hours apart — ask your pharmacist for the best timing with your specific antibiotic.
Is it safe if I have a weakened immune system?
The data are limited in people with weak immunity. Although serious infections from L. acidophilus are rare, they have been reported. Talk with your doctor before starting if you have immune problems or a serious illness.
Will this help my IBS?
The evidence suggests L. acidophilus is possibly effective for IBS. It's not guaranteed to work for everyone, so it's worth trying under your doctor's guidance to see if it helps your symptoms.
What side effects might I experience?
Gas, bloating, stomach discomfort, and diarrhea are uncommon but possible, especially when combined with other probiotics. Rash and itching have been reported once in a trial, though it's not clear if they were caused by this ingredient. Most people tolerate it well.
Can I take this while pregnant or breastfeeding?
We don't have safety data on file for L. acidophilus in pregnancy or lactation. Talk with your doctor or pharmacist about whether it's right for you at that time.
