HelloPharmacist Scorecard of Women's Probiotic 50 Billion by ProBioCare

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 2 of its 11 active ingredients.
  • “Lactobacilli Blend” is a proprietary blend — the label gives one combined amount (35,000,000,000 CFU) without saying how much of each component you get.

Women's Probiotic 50 Billion contains 11 active ingredients: five individual probiotic bacterial strains (Lactobacillus salivarius, L. plantarum, L. acidophilus, L. casei, and Bifidobacterium breve), a prebiotic blend, fructo-oligosaccharides, arabinogalactan, a Lactobacilli Blend, and a proprietary Bifidobacterium Blend. The live bacterial cultures are meant to support healthy gut flora, while the prebiotics (fibers that feed beneficial bacteria) help them thrive.

The capsule also contains inactive ingredients: cellulose, magnesium stearate, silica, and calcium silicate.

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?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • 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).

The evidence for this product's individual ingredients is mixed. Lactobacillus acidophilus is possibly effective for irritable bowel syndrome, antibiotic-associated diarrhea, Helicobacter pylori infection, and bacterial vaginosis.

Fructo-oligosaccharides and arabinogalactan don't have enough reliable evidence to rate them for any condition. For the other probiotic strains in the product, we hold no effectiveness data.

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 4 of the 4 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 4 of 4.
  • General safety write-ups exist for 4 of 4.
  • 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. Bifidobacterium breve is generally well tolerated in healthy people, though caution is advised for those who are very ill or have weakened immune systems.

Arabinogalactan and fructo-oligosaccharides can both cause bloating and flatulence; the good news is that studies show fructo-oligosaccharides at doses under 10 grams per day don't reliably increase these symptoms compared with placebo. Because supplement-level doses of fructo-oligosaccharides and arabinogalactan have limited safety data, check with your doctor before use.

Pregnancy and lactation safety data are not on file for most ingredients in this product — talk with your healthcare provider about whether it's right for you during pregnancy or 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?
  • 3 of the 4 matched ingredients can interact with medications — Lactobacillus Acidophilus, Larch Arabinogalactan, Bifidobacterium Breve.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: immunosuppressants / transplant drugs.
  • For scale: 302 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.

If you take antibiotic drugs, separate your doses from this product — antibiotics can kill the live bacteria before they work. If you take immunosuppressant medications (such as cyclosporine, tacrolimus, or azathioprine after a transplant), check with your doctor or pharmacist first, because the arabinogalactan in this product may interfere with how those drugs work.

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 may be worth considering if you have IBS, antibiotic-associated diarrhea, or bacterial vaginosis, since L. acidophilus shows promise for those. Before you start, check your medications — especially if you take antibiotics or immunosuppressant drugs — using the interaction tool on this page.

Let your doctor or pharmacist know you're thinking about adding it so they can review your full medication list.

Each ingredient & the kinds of drugs it affects

For each ingredient in Women's Probiotic 50 Billion with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.

Lactobacillus acidophilus1 drug type · 182 drugs

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.

Likelihood Probable Evidence D

Bifidobacterium breve1 drug type · 182 drugs

Antibiotic Drugs

Theoretically, taking Bifidobacterium breve with antibiotic drugs might decrease the effectiveness of B. breve.
Since B. breve preparations usually contain live and active organisms, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and B. breve preparations by at least 2 hours.

Likelihood Probable Evidence D

Arabinogalactan1 drug type · 121 drugs

Immunosuppressants

Theoretically, larch arabinogalactan might interfere with immunosuppression therapy due to immunostimulant effects. Immunosuppressant drugs include azathioprine (Imuran), basiliximab (Simulect), cyclosporine (Neoral, Sandimmune), daclizumab (Zenapax), muromonab-CD3 (OKT3, Orthoclone OKT3), mycophenolate (CellCept), tacrolimus (FK506, Prograf), sirolimus (Rapamune), prednisone (Deltasone, Orasone), corticosteroids (glucocorticoids), and other drugs.

Women's Probiotic 50 Billion by ProBioCare: Common Questions

Does Women's Probiotic 50 Billion by ProBioCare interact with any medications?
Yes. Based on its ingredients, Women's Probiotic 50 Billion has a known interaction with 302 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Women's Probiotic 50 Billion contains 11 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 probiotic work if I'm taking antibiotics?
It's unlikely to work well if you take them at the same time — the antibiotic will kill the live organisms in the probiotic. Space your doses apart: take the antibiotic as prescribed, and ask your pharmacist how long to wait before taking the probiotic. You might also ask if you need to restart the probiotic after your course of antibiotics ends.
Can I take this during pregnancy?
The safety data for most ingredients in this product during pregnancy are not on file. Lactobacillus acidophilus alone is rated possibly safe in pregnancy, but we don't have enough information about the others. Talk with your doctor or midwife before starting it — they can weigh the risks and benefits for your situation.
Will it make me bloated?
Bloating and flatulence are possible, especially when you first start — they come from the prebiotic fibers (fructo-oligosaccharides and arabinogalactan) that feed the bacteria. The good news is that studies show these symptoms are usually mild at lower doses and don't always happen. Starting with a smaller dose and building up may help.
Is this actually effective for gut health?
L. acidophilus in this product is possibly effective for irritable bowel syndrome, antibiotic-associated diarrhea, Helicobacter pylori, and bacterial vaginosis. For the other strains and the prebiotic fibers, we don't have enough reliable evidence to say whether they work for specific conditions. Probiotics as a category are still being studied.
What are the inactive ingredients?
The capsule contains cellulose, magnesium stearate, silica, and calcium silicate — standard binders and flow agents. There are no major allergens listed, but if you have sensitivities to any of these, let your pharmacist know.
