HelloPharmacist Scorecard of FloraVantage Balance Probiotic by Bariatric Advantage

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

This product contains 2 active ingredients: a proprietary probiotic blend and Lactobacillus acidophilus NCFM, a beneficial bacteria strain. The blend also includes Bifidobacterium animalis lactis Bi-07.

These are live microorganisms designed to support your gut flora. The capsule itself contains microcrystalline cellulose, hydroxypropylmethylcellulose, magnesium stearate, and silica 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

This product doesn't appear to be marketed for a specific use, so we graded Lactobacillus Acidophilus's overall clinical evidence instead.

Moderate

Some clinical evidence supports Lactobacillus Acidophilus for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredient's overall clinical evidence instead.
  • On file: Antibiotic-associated diarrhea — rated "Possibly Effective" (Natural Medicines).
  • On file: Bacterial vaginosis — rated "Possibly Effective" (Natural Medicines).
  • On file: Helicobacter pylori — rated "Possibly Effective" (Natural Medicines).
  • On file: Irritable bowel syndrome (IBS) — rated "Possibly Effective" (Natural Medicines).

Lactobacillus acidophilus shows possibly effective evidence for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis. It's rated possibly ineffective for atopic disease (allergic conditions), and there isn't enough reliable evidence to rate it for acute respiratory distress syndrome (ARDS).

The effectiveness data we hold doesn't cover Bifidobacterium animalis lactis Bi-07 specifically.

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. That said, because it contains live, active microorganisms, there's a theoretical risk — extremely rare but documented in medical literature — that in certain patients it could cause infection in the bloodstream or other serious sites; most of these cases involved people whose immune systems or gut barriers were already compromised.

Oral use with other probiotics may cause mild gastrointestinal side effects like bloating, flatulence, abdominal pain, or diarrhea, though these are uncommon. One clinical trial reported two rashes and one case of itching, but it's unclear whether those were due to L. acidophilus or the combination.

No pregnancy or lactation safety data is on file for these ingredients.

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 if you're taking any antibiotic drugs — spacing them from this probiotic is important to keep the live bacteria effective. No other major medication interactions are documented for the ingredients we could check, though one strain (Bifidobacterium animalis lactis Bi-07) we were unable to evaluate.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This probiotic may help with IBS, antibiotic-associated diarrhea, or bacterial vaginosis based on the evidence we have. If you're taking antibiotics, space them several hours apart from this product.

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?
FloraVantage Balance 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 I take this if I'm on an antibiotic?
You can, but timing matters. Antibiotics kill the live bacteria in probiotics, so separate the two by a few hours. Talk to your pharmacist about the best schedule for your specific antibiotic.
Will this help my irritable bowel syndrome?
Lactobacillus acidophilus is rated possibly effective for IBS based on the evidence we have, so it's worth trying — but results vary by person. Your doctor or pharmacist can help you decide if it's right for you.

The product contains Lactobacillus acidophilus NCFM and Bifidobacterium animalis lactis Bi-07, both beneficial bacteria strains that naturally live in your gut.
Can this cause side effects?
Most people tolerate it well. Some people report mild bloating, gas, or abdominal discomfort, especially if they're new to probiotics — these are uncommon. Very rarely, in people with weakened immune systems, live probiotics have caused serious infections, so check with your doctor if you're immunocompromised.
Is it safe to take while breastfeeding or pregnant?
We don't have safety data on file for these ingredients during pregnancy or breastfeeding. Talk with your doctor or midwife before starting this product if you're pregnant or nursing.
