HelloPharmacist Scorecard of Pro-Bio by Enzymedica

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 8 active ingredients.
  • “Proprietary Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

Pro-Bio contains 8 ingredients, including a proprietary blend with five types of live Lactobacillus bacteria (L. acidophilus, L. casei, L. paracasei, L. plantarum, L. rhamnosus, and L. salivarius), plus Bacillus subtilis and L. bulgaricus — all probiotics meant to support your gut. The inactive ingredients are gellan gum, cellulose, and water.

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, Diarrhea — 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: Bacillus Subtilis is rated "Possibly Effective" for Antibiotic-associated diarrhea.

The evidence is mixed. L. acidophilus in this product is possibly effective for irritable bowel syndrome, H. pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis.

Bacillus subtilis is possibly effective for antibiotic-associated diarrhea. L. bulgaricus has insufficient evidence to rate for acne, hay fever, diarrhea, asthma, fatty liver disease, and the common cold.

The other ingredients in the blend lack established evidence in our data. Since this is a blend with multiple strains, the real-world benefit depends on whether the combination works better than individual strains — something we don't have information on.

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 3 of the 3 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 3 of 3.
  • General safety write-ups exist for 3 of 3.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

L. acidophilus and Bacillus subtilis are generally well tolerated in healthy adults. Side effects are uncommon but can include mild gastrointestinal symptoms like bloating, flatulence, abdominal discomfort, or diarrhea — particularly when L. acidophilus is combined with other probiotics.

One headache was reported in a trial of Bacillus subtilis. Rarely, live probiotic bacteria can cause serious bloodstream or other infections, especially in very ill or immunocompromised people; these cases are thought to result from bacteria moving from their normal locations in the body.

Safety data for L. bulgaricus are limited, and people who are severely ill or immunocompromised should be cautious. Pregnancy and lactation safety data are not well studied for this supplement — talk with your doctor if you're pregnant or nursing.

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 3 matched ingredients can interact with medications — Lactobacillus Acidophilus, Lactobacillus Delbrueckii, Bacillus Subtilis.
  • 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 start Pro-Bio, double-check any antibiotic drugs you're taking — they can reduce how well the live bacteria in this product work. Separate the timing of antibiotics and Pro-Bio by a few hours if you can.

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.

Pro-Bio may help if you have antibiotic-associated diarrhea or irritable bowel syndrome, though evidence is strongest for the L. acidophilus ingredient. If you take antibiotics, separate them from this product by a few hours.

If you're very ill, immunocompromised, pregnant, or nursing, check with your doctor first. Use the medication checker to make sure your exact drugs won't interfere.

Pro-Bio by Enzymedica: Common Questions

Does Pro-Bio by Enzymedica interact with any medications?
Yes. Based on its ingredients, Pro-Bio 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?
Pro-Bio contains 8 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 Pro-Bio help my antibiotic-related diarrhea?
L. acidophilus and Bacillus subtilis in Pro-Bio are both possibly effective for antibiotic-associated diarrhea. Just time them right — don't take your antibiotic and this probiotic at the same time, because the antibiotic will kill the live bacteria in the supplement. Space them out by a few hours if you can.
What are the most common side effects?
Side effects are uncommon, but when they do happen with probiotics, they're usually mild gut symptoms — bloating, gas, abdominal pain, or diarrhea. One headache was reported in a trial. Most people tolerate it well.
Is it safe to take Pro-Bio if I'm pregnant?
Safety data for this product in pregnancy aren't well studied. Probiotics in food are generally considered fine, but supplement safety is less clear. Talk with your doctor or pharmacist before using it while pregnant or nursing — they can give you personalized advice.
Can I take Pro-Bio if I have a weak immune system?
People who are very ill or immunocompromised should be cautious with live probiotic supplements. Very rarely, the bacteria can cause serious infections in these patients. Check with your doctor before starting this product if your immune system is compromised.
How does Pro-Bio work?
It contains live beneficial bacteria meant to support your gut health. L. acidophilus is possibly effective for irritable bowel syndrome, bacterial vaginosis, H. pylori, and antibiotic-related diarrhea. The other strains lack strong evidence, and we don't know if the combination works better than individual strains.
