HelloPharmacist Scorecard of Maxi Pro 100 Billion by Maxi Health

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 2 of its 2 active ingredients.
  • No proprietary blends here — you can verify the dose of every single component.

Maxi Pro 100 Billion has two active ingredients: Lactobacillus acidophilus and Bifidobacterium bifidum, both live probiotic bacteria. The product also contains inactive ingredients — hypromellose, microcrystalline cellulose, magnesium stearate, and silicon dioxide — which are capsule materials and binders.

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 immune support.
  • 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: Bifidobacterium Bifidum is rated "Possibly Effective" for Irritable bowel syndrome (IBS).

Lactobacillus acidophilus is possibly effective for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis. It's rated possibly ineffective for atopic disease (eczema, allergies), and the evidence for acute respiratory distress syndrome is insufficient to rate.

Bifidobacterium bifidum is possibly effective for IBS and respiratory tract infections. For hay fever, Alzheimer disease, and generalized anxiety disorder, the evidence is insufficient to rate.

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 ingredients are generally well tolerated in healthy adults and children. Because these are live organisms, there's a theoretical concern they could cause serious infection in people with very weakened immune systems — so check with your doctor first if that applies to you.

Gastrointestinal side effects like bloating, flatulence, abdominal discomfort, and diarrhea can occur, though they're uncommon. Rash and itching have been reported rarely in clinical trials with probiotic combinations, though it's unclear whether the probiotics were responsible.

No pregnancy or breastfeeding safety data is on file for either ingredient — talk with your pharmacist or doctor before use if you're pregnant or nursing.

Side effects, ingredient by ingredient Lactobacillus Acidophilus Bifidobacterium Bifidum

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.

Separate this product from any antibiotic drug by a few hours — antibiotics can kill the live probiotics and make this product less effective. Ask your pharmacist what timing works best for your specific antibiotic.

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.

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.

Maxi Pro 100 Billion by Maxi Health: Common Questions

Does Maxi Pro 100 Billion by Maxi Health interact with any medications?
Yes. Based on its ingredients, Maxi Pro 100 Billion 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?
Maxi Pro 100 Billion contains 2 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.
Will this help my irritable bowel syndrome?
Both ingredients are possibly effective for IBS based on the evidence we have, but that's different from proven. Your results may vary, and it's worth discussing with your doctor whether a trial makes sense for your situation.
Can I take this while I'm on an antibiotic?
Not at the same time. Since antibiotics kill the live bacteria in this product, they'd reduce its effectiveness. Space the doses a few hours apart — your pharmacist can tell you the best timing for your specific antibiotic.
What are the common side effects?
Bloating, flatulence, and abdominal discomfort can happen, but they're uncommon. Most people tolerate these probiotics well. If you experience persistent or worsening symptoms, mention it to your pharmacist.
Is it safe if I have a weakened immune system?
These are live organisms, so people with weakened immune systems should talk with their doctor before using this product. Your doctor can assess whether it's right for your situation.
Can I take this while pregnant or breastfeeding?
We don't have safety data on file for either ingredient during pregnancy or breastfeeding. Talk with your pharmacist or doctor — they can give you personalized advice based on your health and the evidence available.
