HelloPharmacist Scorecard of Vital-Dophilus Plus by Klaire Labs

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 0 of its 2 active ingredients.
  • “Probiotic Blend” is a proprietary blend — the label gives one combined amount (480 mg) without saying how much of each component you get.

Vital-Dophilus Plus contains 2 active probiotic ingredients: Lactobacillus rhamnosus and Lactobacillus acidophilus. Both are live bacteria meant to support gut health.

The product also includes vegetarian capsules and L-leucine as inactive ingredients.

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 supplement for digestive health.
  • We looked for evidence on: Antibiotic-associated diarrhea, Bacterial vaginosis, Clostridioides difficile infection, Constipation, Irritable bowel syndrome (IBS), Lactose intolerance — 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, Rotaviral diarrhea, Travelers' diarrhea.

Lactobacillus acidophilus is rated possibly effective for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis. For atopic disease (allergic conditions), it's rated possibly ineffective.

For acute respiratory distress syndrome, the evidence is too limited to rate. We hold no effectiveness data for Lactobacillus rhamnosus.

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. Gastrointestinal side effects—such as stomach discomfort, abdominal pain, indigestion, gas, bloating, diarrhea, vomiting, and burping—are uncommon when taking it orally.

Because live probiotic preparations contain active organisms, there is a theoretical concern they could cause infection in certain patients, though most documented cases appear linked to translocation of bacteria already present in the body. Rashes and itching have been reported in one trial, though it's unclear whether they were due to this ingredient specifically.

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.

Antibiotic drugs are the main concern with this product: taking them at the same time may reduce the probiotic's effectiveness. Space out your doses and ask your pharmacist for the best timing.

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 probiotic may help with IBS, certain infections, and antibiotic-related diarrhea. If you're on antibiotics, check with your pharmacist about timing—you'll want to space out doses.

Because we couldn't check one ingredient and the product contains live organisms, talk to your doctor before starting, especially if your immune system is compromised.

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.

Vital-Dophilus Plus by Klaire Labs: Common Questions

Does Vital-Dophilus Plus by Klaire Labs interact with any medications?
Yes. Based on its ingredients, Vital-Dophilus Plus 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?
Vital-Dophilus Plus 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.
Should I take this at the same time as my antibiotic?
No. Antibiotics can kill the live organisms in this probiotic, which would make it less effective. Ask your pharmacist how far apart to space the doses—typically a few hours is suggested.
Is this safe for kids?
Lactobacillus acidophilus is generally well tolerated in children, but since probiotics contain live organisms, check with your child's doctor before starting.
What's the Probiotic Blend in this product?
The product lists it as an ingredient, but its specific bacterial strains are listed separately as the individual ingredients shown on the label—in this case, the two Lactobacillus species.
Can this cause stomach side effects?
Gas, bloating, and mild stomach discomfort are uncommon but possible when you first take probiotics. Most people tolerate it well.
