HelloPharmacist Scorecard of Lactobacillus Tablets by Health Star

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.

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.

Health Star Lactobacillus Tablets contains two active ingredients: Lactobacillus acidophilus and Lactobacillus bulgaricus. These are beneficial bacteria (probiotics) that support digestive and gut health.

The product also includes several inactive ingredients — whey, sucrose, cellulose, stearic acid, lactose, croscarmellose sodium, nonfat dry milk, magnesium stearate, and silica — which serve as fillers and binders to hold the tablet 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: Probiotic dietary supplement for digestive health.
  • We looked for evidence on: Antibiotic-associated diarrhea, Bacterial vaginosis, Clostridioides difficile infection, Constipation, Inflammatory bowel disease (IBD), 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, Inflammatory bowel disease (IBD), Lactose intolerance, Rotaviral diarrhea.

Lactobacillus acidophilus is possibly effective for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis. The evidence suggests it may help with these conditions, though more research would strengthen that picture.

For atopic disease (allergic and inflammatory conditions), it's rated possibly ineffective. For acute respiratory distress syndrome, there isn't enough reliable evidence to rate it one way or the other.

We have no effectiveness data on file for Lactobacillus bulgaricus.

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. Most people don't experience side effects, though a small number taking it with other probiotics have reported mild gastrointestinal discomfort — bloating, gas, abdominal pain, or loose stools — and these events are uncommon.

Very rarely, in people with certain underlying conditions or compromised immune systems, Lactobacillus has been linked to serious infections like bacteremia or sepsis, though this is thought to occur when bacteria translocate from areas where they naturally live in the body. For pregnancy, the safety data suggests it's possibly safe, though you should check with your doctor before use.

We have no lactation data on file.

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.

Antibiotic drugs are the main concern — taking them at the same time as this product may reduce how well the probiotic works. Space doses several hours apart and let your pharmacist know you're using both.

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 product may help with irritable bowel syndrome, antibiotic-associated diarrhea, and a few other digestive or bacterial conditions if you're looking for probiotics. If you take antibiotics, space them a few hours away from this supplement — otherwise the antibiotic may kill the beneficial bacteria.

Check your exact medications with the tool on this page before you start, and talk with your doctor or pharmacist if you have questions.

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.

Lactobacillus Tablets by Health Star: Common Questions

Does Lactobacillus Tablets by Health Star interact with any medications?
Yes. Based on its ingredients, Lactobacillus Tablets 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?
Lactobacillus Tablets 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.
Can I take this while I'm on antibiotics?
You can, but timing matters. Antibiotics can kill the live bacteria in this probiotic, so separate them by a few hours if you can — take one in the morning and one in the evening. Ask your pharmacist for the best schedule for your specific antibiotic.
What's the difference between the two bacteria in this product?
Both Lactobacillus acidophilus and Lactobacillus bulgaricus are beneficial bacteria that support gut health. We have effectiveness and safety data for acidophilus but not for bulgaricus, so we can't tell you what bulgaricus does on its own.
Will this help my irritable bowel syndrome?
Lactobacillus acidophilus is possibly effective for IBS, meaning the evidence suggests it may help, but it's not a guarantee. How well it works varies from person to person — talk with your doctor about whether it's worth trying for your situation.
Are there any side effects?
Most people tolerate it well. A small number report mild stomach symptoms like bloating, gas, or loose stools, especially when combined with other probiotics. These are uncommon and usually mild. In rare cases with underlying health issues, serious infections have occurred, so check with your doctor before starting if you have a weakened immune system.
Is it safe if I'm pregnant?
Lactobacillus acidophilus is rated possibly safe in pregnancy, but because data are limited, talk with your doctor or pharmacist before you start — they can give you personalized advice based on your situation.
Does this product have fillers?
Yes — it contains whey, sucrose, cellulose, lactose, and several other inactive ingredients that help hold the tablet together. If you're allergic or sensitive to milk or any of these, check the full ingredient list with your pharmacist first.
