HelloPharmacist Scorecard of Ultimate Friendly Flora Probiotic 25 Billion CFU by ProCaps

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

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 4 active ingredients.
  • “Total CFU” is listed as a grouped ingredient — the label doesn't break down how much of each component you get.

This probiotic contains four active ingredients: Lactobacillus plantarum LP-115, Lactobacillus acidophilus LA-14, Lactobacillus paracasei UALpc-04, and Bifidobacterium animalis lactis. Together they deliver 25 billion colony-forming units (CFU) — a measure of live bacterial cells.

These are live microorganisms meant to support your gut flora. The capsule itself is filled with inactive ingredients like cellulose, silica, and magnesium stearate, which help hold the product together and keep it stable.

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: comprehensive probiotic complex for digestive health.
  • We looked for evidence on: Antibiotic-associated diarrhea, Bacterial vaginosis, Clostridioides difficile infection, Colic, Constipation, Irritable bowel syndrome (IBS) — 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: Lactobacillus Acidophilus is rated "Insufficient Reliable Evidence To Rate" for Constipation, Lactose intolerance, Necrotizing enterocolitis (NEC), Rotaviral diarrhea.

Lactobacillus acidophilus has been rated possibly effective for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis. It's rated possibly ineffective for atopic disease (allergic conditions), and the evidence isn't established for acute respiratory distress syndrome.

We don't have effectiveness data on file for the other three active bacterial strains in this product.

The evidence, ingredient by ingredient Lactobacillus Acidophilus

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.

Lactobacillus acidophilus is generally well tolerated in healthy adults and children. That said, because it contains live microorganisms, there's a small theoretical risk of infection in some patients — isolated cases of serious conditions like bacteremia (bacteria in the bloodstream) and endocarditis (heart infection) have been reported, though these mostly happened in people where the bacteria traveled from elsewhere in the body.

When taking this probiotic with other probiotics, some people have reported mild gastrointestinal side effects like bloating, gas, abdominal pain, or diarrhea, but these are uncommon. We don't have pregnancy or breastfeeding safety data on file for any of the ingredients.

Side effects, ingredient by ingredient Lactobacillus Acidophilus

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 — Lactobacillus Acidophilus.
  • 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 medication type to double-check with this product (Moderate severity). Taking them together can reduce the probiotic's effectiveness — ask your pharmacist how to space them apart.

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.

This product may help with IBS, antibiotic-associated diarrhea, and a few other gut-related conditions if the Lactobacillus acidophilus works for you. If you're on antibiotics, space them away from this probiotic.

Check your exact medications with the tool on this page, and talk with your pharmacist or doctor before starting, especially if you have a weakened immune system or serious underlying health issues.

Formula

Comprehensive probiotic complex Five essential beneficial strains 25 Billion CFU

Ultimate Friendly Flora Probiotic is a comprehensive blend of five established, beneficial probiotic strains, delivering an exceptional 25 billion colony forming units (CFU) per capsule. Probiotic means “for life” and probiotic-rich foods have been consumed for thousands of years. However, our diet is no longer rich in microflora with yogurt remaining one of its only sources, which typically contains unwanted calories and sugar and only provides unreliable levels of a single strain of microflora. There are trillions of beneficial microorganisms (microflora) in our body and their healthy balance is essential to the health of our digestive and immune systems. Our Ultimate Friendly Flora Probiotic is designed to enhance the balance of these microorganisms in our digestive, immune, urinary and genital systems. It is well established that the microflora in our GI (gastrointestinal) tract play a vital role in promoting healthy digestion, including nutrient absorption and regularity. Maintaining a proper balance of our microflora is also essential to healthy immune system function. The delicate balance of microflora is easily upset by stress, poor diet, digestive issues and aging. This fragile balance is further disrupted by medications that affect the digestive system and its pH balance, such as antacids or antibiotics, which can entirely wipe out our microflora. Ultimate Friendly Flora Probiotic provides 25 billion colony forming units per capsule of five carefully selected varieties of established, beneficial microflora to ensure the essential benefits of these remarkably healthy “friends.”

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.

Ultimate Friendly Flora Probiotic 25 Billion CFU by ProCaps: Common Questions

Does Ultimate Friendly Flora Probiotic 25 Billion CFU by ProCaps interact with any medications?
Yes. Based on its ingredients, Ultimate Friendly Flora Probiotic 25 Billion CFU 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?
Ultimate Friendly Flora Probiotic 25 Billion CFU contains 4 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.
What exactly are these live bacteria supposed to do?
Probiotics are meant to support the natural bacteria in your gut. The evidence we hold shows that Lactobacillus acidophilus may help with irritable bowel syndrome, antibiotic-associated diarrhea, bacterial vaginosis, and H. pylori infection. We don't have effectiveness data for the other three strains in this product.
Can I take this while I'm on an antibiotic?
Not at the same time. Antibiotics can kill the live bacteria in the probiotic, making it less effective. Ask your pharmacist or doctor how many hours apart you should take them — spacing them out is usually the fix.
What side effects should I watch for?
Most people tolerate this product fine. Mild gastrointestinal side effects like bloating, gas, or abdominal discomfort can happen, but they're uncommon. If you experience anything unusual or persistent, check with your pharmacist.
Is it safe if I have a weak immune system?
Because this product contains live microorganisms, there's a small theoretical risk for people with weakened immunity. Talk with your doctor or pharmacist before starting — they can tell you whether it's right for your situation.
Can I take this if I'm pregnant or breastfeeding?
We don't have safety data on file for any of the ingredients during pregnancy or breastfeeding. That means we can't say either way. Talk with your doctor or pharmacist for personalized advice.
What's in the capsule besides the bacteria?
The capsule contains plant cellulose, microcrystalline cellulose, silica, and magnesium stearate — these are standard inactive ingredients that help stabilize and deliver the product.
