HelloPharmacist Scorecard of Multi-Flora Probiotic by Vitamer Laboratories

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

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.

Multi-Flora Probiotic contains 5 active ingredients, all of them live bacterial strains commonly found in fermented foods and your own gut. The main ones are Lactobacillus acidophilus and Bifidobacterium bifidum, which are well-studied probiotics believed to support digestive and immune health.

The product also includes Lactobacillus lactis, Lactobacillus reuteri, and Lactobacillus plantarum — a blend designed to deliver a mix of beneficial species. The inactive ingredients are Jerusalem Artichoke, a vegetable capsule, cellulose, medium chain triglycerides, and water — these serve as fillers and the capsule itself.

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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • The label markets general wellness (“digestive health support”), not a specific health condition, so there is no single claim to grade against clinical-evidence data.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Antibiotic-associated diarrhea — rated "Possibly Effective" (Lactobacillus Acidophilus) (Natural Medicines).
  • On file: Bacterial vaginosis — rated "Possibly Effective" (Lactobacillus Acidophilus) (Natural Medicines).
  • On file: Helicobacter pylori — rated "Possibly Effective" (Lactobacillus Acidophilus) (Natural Medicines).
  • On file: Irritable bowel syndrome (IBS) — rated "Possibly Effective" (Lactobacillus Acidophilus) (Natural Medicines).
  • On file: Respiratory tract infections — rated "Possibly Effective" (Bifidobacterium Bifidum) (Natural Medicines).

L. acidophilus is possibly effective for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis. Bifidobacterium bifidum is possibly effective for IBS and respiratory tract infections.

For other conditions listed in our data — like allergic rhinitis (hay fever), Alzheimer disease, and generalized anxiety disorder — we don't have enough reliable evidence to say one way or the other. The other three Lactobacillus strains in this product don't have effectiveness ratings in our data.

The evidence, ingredient by ingredient Lactobacillus Acidophilus Bifidobacterium Bifidum

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Both L. acidophilus and B. bifidum are generally well tolerated in healthy adults and children. That said, the safety data are limited in some areas, so it's worth checking with your doctor before you start, especially if you have a weakened immune system — probiotics carry a theoretical risk of infection in people who are immunocompromised.

Common side effects are usually mild and rare: bloating, flatulence, abdominal discomfort, and gas. In clinical trials, rashes and itching have occasionally been reported, though it's unclear which ingredient — or the combination itself — caused them.

L. acidophilus contains live organisms, which means there's a small theoretical concern about serious infections (like sepsis or bacteremia) in very specific circumstances; most documented cases appear to be due to bacteria moving from other parts of the body rather than from the supplement itself. For pregnancy, L. acidophilus is rated possibly safe; we have no lactation data on file for either ingredient.

Because evidence is limited, talk with your doctor or pharmacist about whether this product is right for you during pregnancy or while breastfeeding.

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?
  • 2 of the 2 matched ingredients can interact with medications — Lactobacillus Acidophilus, Bifidobacterium Bifidum.
  • 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.

Before you take Multi-Flora Probiotic, double-check with your doctor or pharmacist if you're on antibiotics. The live bacteria in this product can be killed off if you take them at the same time, making the probiotic less effective.

Time your doses apart — your healthcare provider can advise you on the best schedule for your situation.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This probiotic blend is generally well tolerated and may help with IBS, antibiotic-related diarrhea, and a few other digestive concerns. The main thing to watch is taking it separately from antibiotics — at least a few hours apart — so the antibiotics don't kill off the live bacteria.

If you're immunocompromised or pregnant, or if you take any regular medications, talk it over with your doctor or pharmacist before you start.

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.

Multi-Flora Probiotic by Vitamer Laboratories: Common Questions

Does Multi-Flora Probiotic by Vitamer Laboratories interact with any medications?
Yes. Based on its ingredients, Multi-Flora 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?
Multi-Flora 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.
Can I take this probiotic while I'm on an antibiotic?
Yes, but timing matters. Taking them together might kill off the live bacteria in the probiotic before they work. Instead, separate them — usually a few hours apart — and ask your doctor or pharmacist exactly when to take each one based on your antibiotic.
What does this probiotic do?
The strains in here are possibly effective for irritable bowel syndrome, antibiotic-associated diarrhea, bacterial vaginosis, and a few other digestive concerns. For respiratory infections and allergies, there isn't enough reliable evidence yet to say whether it helps.
What are the side effects?
Most people tolerate it well. Mild gas, bloating, and abdominal discomfort can happen, but they're uncommon. Rashes and itching have been reported in one trial, though it's unclear if the probiotic caused them. Serious infections from probiotics are very rare and usually only happen in people with weakened immune systems.
Is it safe to take while pregnant?
L. acidophilus is rated possibly safe in pregnancy, but we don't have enough data to be sure either way. Talk with your doctor or pharmacist about whether this product is right for you during pregnancy — they can weigh the possible benefits against any individual concerns.
Is this safe if I have a weakened immune system?
Because probiotics contain live organisms, people with weakened immune systems should be cautious. Check with your doctor before you start, since there's a theoretical risk of infection in that situation.
Does this product have any fillers?
Yes — there are inactive ingredients including Jerusalem Artichoke, cellulose, medium chain triglycerides, and water, plus the vegetable capsule itself.
