HelloPharmacist Scorecard of MetaKids Probiotic by Metagenics

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 2 active ingredients.
  • “A Probiotic Blend of” is a proprietary blend — the label gives one combined amount (107.80 mg) without saying how much of each component you get.

MetaKids Probiotic contains two active probiotic strains: Lactobacillus acidophilus NCFM and Bifidobacterium animalis lactis Bi-07. Both are live microorganisms designed to support healthy gut bacteria in children.

The inactive ingredients — xylitol, natural flavors, sorbitol, and others — serve as binders, thickeners, and taste enhancers.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Lactobacillus Acidophilus's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: immune health support for children.
  • We looked for evidence on: Respiratory tract infections, immune function, infection prevention, children's immunity.
  • The closest evidence on file: Lactobacillus Acidophilus is rated "Insufficient Reliable Evidence To Rate" for Respiratory tract infections (Natural Medicines).

Lactobacillus acidophilus is 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 and there's insufficient evidence to rate it for acute respiratory distress syndrome.

We hold no effectiveness data for the Bifidobacterium animalis lactis Bi-07 strain 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 children. Most gastrointestinal side effects — like bloating, abdominal discomfort, or diarrhea — are uncommon when taken orally.

In rare cases, the live organisms in probiotic products might theoretically cause infection in patients with certain immune system issues, though this is not typical in healthy kids. Because data are limited, check with your child's doctor before starting, especially if they have a compromised immune system or are in the hospital.

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, space out the timing — antibiotics may kill off the live organisms in this probiotic. Check with your child's doctor or pharmacist about how far apart to take them.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This probiotic may help with certain digestive issues like antibiotic-related diarrhea, though the evidence is still developing. The main caution is timing it away from antibiotics — they'll cancel each other out if taken together.

Talk with your child's doctor or pharmacist before starting, particularly if your child is on any medications or has ongoing health concerns.

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.

MetaKids Probiotic by Metagenics: Common Questions

Does MetaKids Probiotic by Metagenics interact with any medications?
Yes. Based on its ingredients, MetaKids 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?
MetaKids 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 my child take this while on antibiotics?
Not at the same time. Antibiotics can kill the live bacteria in this probiotic, making it less effective. Ask your pharmacist or doctor how long to wait between doses — usually a few hours is enough.
What's the difference between the two probiotics in this product?
Both Lactobacillus acidophilus and Bifidobacterium animalis lactis are beneficial bacteria meant to support gut health. We have effectiveness data on the acidophilus strain but not the detailed breakdown on the Bi-07 strain alone.
Is this safe for healthy kids?
Generally, yes — it's well tolerated in healthy children. Mild side effects like bloating or stomach discomfort can happen but are uncommon. If your child has immune system issues or is hospitalized, check with their doctor first.
Does this actually help with diarrhea?
Lactobacillus acidophilus is rated possibly effective for diarrhea linked to antibiotic use. The evidence isn't definitive, but it's one of the better-studied uses for this strain.
What are all these inactive ingredients for?
Xylitol and sorbitol add sweetness for kids, while things like microcrystalline cellulose and magnesium stearate help hold the tablet together. They don't add therapeutic value — just make the product easier to take.
