HelloPharmacist Scorecard of UltraFlora Children's 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.

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 50:50 Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

UltraFlora Children's contains 2 active probiotic ingredients: Lactobacillus acidophilus NCFM Strain and Bifidobacterium lactis Bi-07. Probiotics are beneficial live bacteria that support digestive and immune health.

The product also includes inactive ingredients like xylitol, sorbitol, natural flavors, and cellulose for texture and taste.

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: support immune health in children.
  • We looked for evidence on: Antibiotic-associated diarrhea, Atopic disease, Atopic dermatitis (eczema), Colic, Constipation, Inflammatory bowel disease (IBD) — 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 "Possibly Ineffective" for Atopic disease.

Lactobacillus acidophilus has possibly effective evidence for irritable bowel syndrome (IBS), infections caused by Helicobacter pylori bacteria, antibiotic-associated diarrhea, and bacterial vaginosis. For atopic disease (allergic conditions), the evidence suggests it may not be effective.

For acute respiratory distress syndrome, we don't have enough reliable evidence to rate it. We hold no effectiveness data for Bifidobacterium lactis Bi-07.

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, though your doctor should sign off before you use it. Gastrointestinal side effects like stomach discomfort, bloating, gas, or mild diarrhea can occur but are uncommon.

Since these are live bacteria, there's a theoretical concern about infection in certain patients, though this is rare and usually involves translocation (movement) of bacteria from other body sites. One clinical trial reported rash and itching with a probiotic combination, but it's unclear whether L. acidophilus was the cause.

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 product — it may reduce the probiotic's effectiveness if taken at the same time. Separate the doses by a few hours if your child is on antibiotics.

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 probiotic may help with certain digestive issues and bacterial infections in children. The main caution is spacing doses away from antibiotics so the beneficial bacteria survive.

Ask your pharmacist before starting, especially if your child is on an antibiotic.

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.

How can one product interact with so many drugs?

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 while they're on an antibiotic?
Not at the same time. Antibiotics can kill the live bacteria in the probiotic. Ask your pharmacist how many hours to space them apart — usually a few hours works well.
What are these bacteria supposed to do?
Lactobacillus acidophilus supports digestive health and may help with IBS, diarrhea after antibiotics, and certain bacterial infections. Bifidobacterium lactis is also a beneficial bacteria, though we don't have effectiveness data for it in our system.
Are there any side effects I should watch for?
Gas, bloating, stomach discomfort, or mild diarrhea can happen but are uncommon. A rash was reported once in a trial with a probiotic mix, though it's unclear if the L. acidophilus caused it. Call your doctor if your child has unusual symptoms.
Is this safe for kids?
Lactobacillus acidophilus is generally well tolerated in healthy children. Still, check with your child's doctor before starting, especially if they have a weakened immune system or are very ill.
What's in this besides the probiotics?
The other ingredients are sweeteners (xylitol and sorbitol), natural flavors, and common binders and fillers like cellulose and silica.
