HelloPharmacist Scorecard of Primadophilus Kids Probiotic Chewables 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 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 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.

This product has 3 active ingredients: Lactobacillus acidophilus LA-14, Lactobacillus plantarum LP-115, and Bifidobacterium — all live probiotic bacteria meant to support digestive and immune health. These come in a chewable tablet sweetened with xylitol and flavored with cherry, plus inactive ingredients like inulin (a prebiotic fiber), cellulose, and magnesium stearate.

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, Colic, 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 LA-14 is possibly effective for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis. It's rated possibly ineffective for atopic disease (eczema and related conditions), and the evidence for acute respiratory distress syndrome is too limited to rate.

We don't have effectiveness data on file for the other two probiotic 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. Gastrointestinal side effects like stomach discomfort, bloating, gas, diarrhea, or burping are possible but uncommon when taken with other probiotics.

Because these are live organisms, there's a theoretical concern they could cause infection in certain patients — most commonly in those with compromised immunity or underlying conditions — though this is rare. The safety data for this ingredient in pregnancy is rated possibly safe, but data are limited; talk with your child's doctor or pharmacist before use if you have questions.

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.

Check antibiotic drugs before giving this to your child. Taking antibiotics at the same time as this probiotic may reduce how well the probiotic works, so your pharmacist can help you 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 is a well-tolerated probiotic blend for kids that may help with IBS, antibiotic-related diarrhea, and a few other digestive concerns. If your child takes antibiotics, separate the timing — don't give them together.

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.
