HelloPharmacist Scorecard of UltraFlora Balance 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

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 2 active ingredients.
  • “A Proprietary Probiotic Blend” is a proprietary blend — the label gives one combined amount (55 mg) without saying how much of each component you get.

UltraFlora Balance contains 2 active ingredients: Lactobacillus acidophilus NCFM and Bifidobacterium lactis Bi-07. Both are live-culture probiotics — beneficial bacteria meant to support digestive health.

The product also includes microcrystalline cellulose, magnesium stearate, silica, and a capsule shell as inactive ingredients.

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: healthy intestinal environment and immune health.
  • We looked for evidence on: Antibiotic-associated diarrhea, Bacterial vaginosis, Clostridioides difficile infection, 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 Bacterial vaginosis, Irritable bowel syndrome (IBS).
  • Also on file: Lactobacillus Acidophilus is rated "Insufficient Reliable Evidence To Rate" for Constipation, Inflammatory bowel disease (IBD), Lactose intolerance, Necrotizing enterocolitis (NEC).

Lactobacillus acidophilus is possibly effective for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis based on the evidence we hold. It's rated possibly ineffective for atopic disease, and we don't have enough reliable evidence to rate it for acute respiratory distress syndrome.

We have no effectiveness data on file for Bifidobacterium lactis Bi-07 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. Since it contains live, active microorganisms, there's some concern it could theoretically cause infection in certain patients — though such cases are rare and usually occur when bacteria spread from areas where they naturally live.

Minor gastrointestinal side effects like bloating, gas, abdominal discomfort, or diarrhea are uncommon but can happen, especially when combined with other probiotics. Talk with your doctor before starting this product, especially if you have a compromised immune system or serious underlying illness.

We have no safety data on file for Bifidobacterium lactis Bi-07.

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 documented concern — they can reduce how well this probiotic works. We couldn't verify interactions for Bifidobacterium lactis Bi-07, so check your full medication list with the search tool on this page before starting.

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.

UltraFlora Balance may help if you have IBS, antibiotic-related diarrhea, or certain infections — but the evidence is preliminary. The main thing to watch is antibiotics: they can kill off the live bacteria in this product, so space out your doses.

If you're on any medications at all, check them below, and ask your pharmacist about timing.

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.

UltraFlora Balance by Metagenics: Common Questions

Does UltraFlora Balance by Metagenics interact with any medications?
Yes. Based on its ingredients, UltraFlora Balance 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?
UltraFlora Balance 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 I take this with antibiotics?
Not at the same time. Antibiotics kill the live bacteria in this product, so you'll want to separate when you take them — ask your pharmacist for the best spacing. The product may be less effective if you take them together.
What's the difference between the two probiotics in here?
Both are beneficial bacteria that live in your gut. Lactobacillus acidophilus and Bifidobacterium lactis Bi-07 are different strains that work together to support digestive health, though the science behind this particular blend is limited in our data.
Will this give me side effects?
Uncommon, but some people experience mild gas, bloating, or stomach discomfort — especially at first or if they're also taking other probiotics. These usually settle down. If you have a weak immune system or serious illness, talk to your doctor first, since live probiotics carry a theoretical risk in those cases.
Can I take this while pregnant or breastfeeding?
We don't have safety data on file for either ingredient during pregnancy or lactation. Talk with your doctor or pharmacist about whether this product is right for you in those situations.
Does this actually work for IBS?
The evidence says it's possibly effective — meaning there's some research support, but it's not definitive. Results vary from person to person, so it may help you, but it's not guaranteed.
