HelloPharmacist Scorecard of PureProbiotic by Pure Encapsulations

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

PureProbiotic contains 6 active probiotic ingredients: Lactobacillus rhamnosus LR-32, Lactobacillus plantarum LP-115, Lactobacillus acidophilus LA-14, Bifidobacterium bifidum Bb-06, Bifidobacterium breve Bb-18, and Bifidobacterium animalis lactis Bb-04. These are all live bacteria meant to support your gut health.

The product also contains two inactive ingredients — cellulose and water — that serve as fillers and capsule material.

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).
  • On file: Respiratory tract infections — rated "Possibly Effective" (Bifidobacterium Bifidum) (Natural Medicines).

The evidence for these strains is mixed. Lactobacillus acidophilus is possibly effective for irritable bowel syndrome, Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis.

Bifidobacterium bifidum is possibly effective for irritable bowel syndrome and respiratory tract infections. Bifidobacterium breve has insufficient reliable evidence for the conditions studied.

For several other conditions — atopic disease, hay fever, anxiety, cognitive decline, and sepsis — the data either show insufficient evidence or suggest these strains are possibly ineffective.

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.

Overall, these probiotic strains are generally well tolerated in healthy adults and children. Gastrointestinal side effects like bloating, flatulence, abdominal discomfort, and diarrhea can occur, but they're uncommon.

There's a theoretical concern that because these are live organisms, they could rarely cause infection in people with weakened immune systems or those who are critically ill — cases of bacteremia and sepsis have been reported, though most are rare. If you're immunocompromised or severely ill, check with your doctor before starting.

Lactobacillus acidophilus and Bifidobacterium bifidum are both rated possibly safe in pregnancy; data for Bifidobacterium breve in pregnancy and lactation are not on file.

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, Bifidobacterium Breve, 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.

Antibiotic drugs are the main concern — they can reduce how well these probiotics work. Since this product contains live organisms, antibiotics taken at the same time may kill a significant number of them.

Talk to your pharmacist about spacing them at least several hours apart. No other medication interactions are documented for the ingredients we could check.

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 product may help with certain digestive issues like irritable bowel syndrome and antibiotic-associated diarrhea, though the evidence is strongest for Lactobacillus acidophilus. The main thing to watch for is timing with antibiotics — you'll need to space them apart so the antibiotics don't kill the live bacteria in this product.

If you have a weakened immune system or are critically ill, talk to your doctor before starting. Check your exact medications with your doctor or pharmacist before you begin.

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.

PureProbiotic by Pure Encapsulations: Common Questions

Does PureProbiotic by Pure Encapsulations interact with any medications?
Yes. Based on its ingredients, PureProbiotic 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?
PureProbiotic contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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 while I'm on an antibiotic?
Not at the same time. Antibiotics can kill the live bacteria in this probiotic, making it less effective. Ask your pharmacist how many hours apart to take them — usually they recommend spacing them out during the day.
Is this safe if I have a weak immune system?
You should check with your doctor first. While these probiotics are generally well tolerated in healthy people, those with weakened immune systems need to be cautious because there's a theoretical risk of infection from the live organisms.
What side effects might I get?
Bloating, flatulence, abdominal discomfort, and diarrhea can happen, but they're uncommon. Rashes have been reported in rare cases with probiotic combinations, though it's unclear whether they were due to the probiotics themselves.
Will this help my irritable bowel syndrome?
Lactobacillus acidophilus and Bifidobacterium bifidum in this product are possibly effective for IBS, meaning some evidence supports their use, but it's not definitive. Talk to your doctor about whether to try it for your specific situation.
Is it safe to take while pregnant?
Lactobacillus acidophilus and Bifidobacterium bifidum are rated possibly safe in pregnancy. We don't have pregnancy safety data for the other strains in this product, so ask your doctor or midwife before starting.
