HelloPharmacist Scorecard of Pre+Probiotic by Priority One Nutritional Supplements

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.

This product contains 2 active ingredients. The first is Lactospore, a strain of live Bacillus coagulans bacteria — a type of probiotic designed to support your gut.

The second ingredient is PreticX 95P, which we couldn't find interaction or effectiveness data for in our system. The capsule also contains inactive ingredients like silicon dioxide and purified water to hold everything together.

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: Constipation, Diarrhea, Dyspepsia, Flatulence, Irritable bowel syndrome (IBS), Antibiotic-associated diarrhea — and 4 related terms.
  • The strongest evidence on file: Bacillus Coagulans is rated "Possibly Effective" for Constipation (Natural Medicines).
  • Also on file: Bacillus Coagulans is rated "Possibly Effective" for Irritable bowel syndrome (IBS).
  • Also on file: Bacillus Coagulans is rated "Insufficient Reliable Evidence To Rate" for Antibiotic-associated diarrhea, Diarrhea, Dyspepsia, Flatulence, and more.

Lactospore (Bacillus coagulans) is possibly effective for constipation and irritable bowel syndrome (IBS). For other uses listed — antibiotic-associated diarrhea, athletic performance, cancer prevention, and fatty liver disease — the evidence isn't established in our data.

PreticX 95P's effectiveness data isn't on file.

The evidence, ingredient by ingredient Bacillus Coagulans

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.

Bacillus coagulans is generally well tolerated in healthy adults, though product quality varies between brands. That said, there isn't enough reliable safety data to cover every situation, so talk to your doctor before using — especially if you're severely ill, immunocompromised, or have a central line or other indwelling catheter, as rare cases of serious infection have been reported in those groups.

Pregnancy and lactation safety data for this product isn't on file; ask your doctor or pharmacist whether it's right for you.

Side effects, ingredient by ingredient Bacillus Coagulans

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 — Bacillus Coagulans.
  • 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.

If you're taking antibiotics, separate them from this product — don't take them together, as the antibiotics may kill the beneficial bacteria and reduce the probiotic's effectiveness. No other interactions are documented for the ingredients we could check.

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.

If you're dealing with constipation or IBS and have a healthy immune system, this probiotic may help. Just don't take it at the same time as antibiotics — space them several hours apart.

If you're on any medications or have a weakened immune system, check with your pharmacist first.

Antibiotic Drugs

Theoretically, taking antibiotics with Bacillus coagulans might decrease the effectiveness of B. coagulans.
B. coagulans 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 B. coagulans preparations by at least two hours.

Pre+Probiotic by Priority One Nutritional Supplements: Common Questions

Does Pre+Probiotic by Priority One Nutritional Supplements interact with any medications?
Yes. Based on its ingredients, Pre+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?
Pre+Probiotic 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.
Can I take this with my antibiotic?
Not at the same time. Antibiotics can kill the live bacteria in this probiotic and make it less effective. Take your antibiotic at one time of day and this product several hours apart — ask your pharmacist for the exact timing that works best for your antibiotic.
Does this really help with IBS or constipation?
Bacillus coagulans (Lactospore) is possibly effective for both. That means there's some evidence it can help, but it's not a guarantee — results vary. Give it a fair trial and track how you feel.
Is this safe if I'm pregnant or breastfeeding?
We don't have safety data on file for pregnancy or lactation with this product. Talk to your doctor or pharmacist — they can help you weigh the benefits and risks for your situation.
What's Lactospore?
It's a live strain of beneficial bacteria called Bacillus coagulans. Probiotics like this are meant to support your gut health and digestion.
What's PreticX 95P for?
We don't have effectiveness data for that ingredient on file, so I can't tell you what it's designed to do. You might check the product label or contact the manufacturer for more details.
