HelloPharmacist Scorecard of Primadophilus Kids Cherry Flavored by Nature's Way

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 Sep 3, 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 3 active ingredients.
  • “Proprietary Probiotic Blend” is a proprietary blend — the label gives one combined amount (28 mg) without saying how much of each component you get.

Primadophilus Kids contains three active probiotic strains: Lactobacillus acidophilus (La-14), Lactobacillus plantarum (LP-115), and Bifidobacterium bifidum/lactis (Bb-02). These are live beneficial bacteria meant to support digestive health.

The inactive ingredients include xylitol (a sweetener), inulin (a prebiotic fiber), and standard tablet binders like hydroxypropyl cellulose and magnesium stearate, plus natural cherry flavoring.

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: Supports healthy digestive flora.
  • We looked for evidence on: Antibiotic-associated diarrhea, Clostridioides difficile infection, Constipation, Irritable bowel syndrome (IBS), Lactose intolerance, Rotaviral 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 Irritable bowel syndrome (IBS).
  • Also on file: Lactobacillus Acidophilus is rated "Insufficient Reliable Evidence To Rate" for Constipation, Lactose intolerance, Rotaviral diarrhea, Travelers' diarrhea, and more.

Lactobacillus acidophilus has been studied for several digestive and health concerns. The evidence shows it is possibly effective for irritable bowel syndrome (IBS), antibiotic-associated diarrhea, and bacterial vaginosis, and possibly effective for Helicobacter pylori infection.

For atopic disease (allergic conditions), the evidence suggests it's possibly ineffective. For acute respiratory distress syndrome, there isn't enough reliable evidence to rate it.

We don't have effectiveness data on file for the other two strains in this blend.

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 children and adults. The live organisms it contains do carry a theoretical risk of infection in patients with severely weakened immune systems, though this is uncommon.

Gastrointestinal side effects like bloating, gas, abdominal discomfort, or mild diarrhea can occur when taking it with other probiotics, but these are unusual. During pregnancy, L. acidophilus is rated possibly safe; for breastfeeding, we don't have safety data on file.

Check with your child's doctor or pharmacist before starting, especially if your child has immune system concerns.

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.

If your child takes antibiotic drugs, separate the timing of the antibiotic and this probiotic by several hours—ask your pharmacist exactly how—so the antibiotic doesn't reduce the probiotic's effectiveness. We don't have interaction data for the other two probiotic strains in this product, so check your child's full medication list with your pharmacist to be sure.

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.

Primadophilus Kids is a three-strain probiotic aimed at children's digestive health, with the strongest evidence for IBS and antibiotic-associated diarrhea. The main thing to watch for is timing with antibiotics—separate them by a few hours so the antibiotic doesn't kill the beneficial bacteria.

If your child is on other medications or has immune concerns, talk it over with your child's doctor or pharmacist before you start.

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.

Primadophilus Kids Cherry Flavored by Nature's Way: Common Questions

Does Primadophilus Kids Cherry Flavored by Nature's Way interact with any medications?
Yes. Based on its ingredients, Primadophilus Kids Cherry Flavored 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?
Primadophilus Kids Cherry Flavored contains 3 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 give this to my child if they're on antibiotics?
Yes, but timing matters. The antibiotic can kill the live bacteria in the probiotic if you give them at the same time. Ask your child's pharmacist how many hours to separate them—typically a couple of hours apart is enough to let the antibiotic work without damaging the probiotic.
What does each probiotic strain in here do?
Lactobacillus acidophilus is studied most and shows promise for irritable bowel syndrome, antibiotic-associated diarrhea, and a few other digestive and bacterial concerns. The other two strains—Lactobacillus plantarum and Bifidobacterium bifidum/lactis—are included for digestive support, but we don't have published effectiveness data on file for them specifically.
Is it okay for a pregnant or breastfeeding mother to take this?
Lactobacillus acidophilus is rated possibly safe in pregnancy. We don't have safety data on breastfeeding or the other two strains. If you're pregnant or nursing, talk with your doctor or pharmacist before starting.
What side effects should I watch for?
Most kids tolerate it well. Occasionally, mild bloating, gas, or soft stools can happen, especially when starting. If your child has a severely weakened immune system, there's a very small theoretical risk of infection; mention that to your doctor when starting.
Does this product have any fillers?
It has inactive ingredients like xylitol (sweetener), inulin, hydroxypropyl cellulose, and magnesium stearate, which help form and flavor the tablet. These are standard and generally well tolerated, but if your child has a sensitivity to any of them, let your pharmacist know.
