HelloPharmacist Scorecard of Gastro Flora by NutriCology
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
Gastro Flora contains 4 active probiotic ingredients: three Lactobacillus strains (casei, rhamnosus, and acidophilus) and one Bifidobacterium strain (longum). These are live, beneficial bacteria meant to support gut health.
The capsule also contains inactive ingredients including fructooligosaccharides (a prebiotic fiber that feeds probiotics), hydroxypropyl methylcellulose (the capsule material), rice flour, and stearic acid.
Does it work?
Moderate evidence
The data we hold shows L. acidophilus is possibly effective for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis. For B. longum, the evidence in our data is insufficient to rate it for the conditions studied—age-related cognitive decline, allergic rhinitis (hay fever), antibiotic-associated diarrhea, generalized anxiety disorder (GAD), asthma, and athletic performance.
We hold no effectiveness ratings for the other two strains.
How safe is it?
Well-documented data
L. acidophilus is generally well tolerated in healthy adults and children, though you should check with your doctor before starting. B. longum is generally well tolerated in healthy people but warrants caution if you're seriously ill or immune-compromised.
In rare cases, both organisms have been isolated in serious infections like bacteremia and sepsis, mostly in critically ill or immunocompromised patients. Gastrointestinal side effects—abdominal discomfort, bloating, flatulence, and diarrhea—are uncommon with these probiotics alone but may occur, especially in combination products.
Meds to double-check
Moderate interaction found
Before taking Gastro Flora, check with your doctor or pharmacist about any antibiotic drugs you're taking—the most serious interaction is Moderate severity, where antibiotics can reduce the supplement's effectiveness. If you take antibiotics, ask your provider how to time them separately from this supplement.
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.
Gastro Flora may be worth considering if you're looking for probiotics to support gut health, particularly if you have IBS or antibiotic-associated diarrhea. The main thing to watch for is timing around antibiotics—space them several hours apart so the antibiotic doesn't kill the probiotics.
If you're seriously ill, immunocompromised, or pregnant, talk with your doctor or pharmacist first.

Gastro Flora by NutriCology Drug Interactions
HelloPharmacist Interaction Report
Gastro Flora by NutriCology contains four probiotic strains.
Through its Lactobacillus acidophilus and Bifidobacterium longum content, the product interacts with antibiotic drugs — a Moderate severity interaction where antibiotics might kill the live organisms in the supplement and reduce its effectiveness.
Read the full breakdown — every affected drug type, severity by severity
Both L. acidophilus and B. longum are living microorganisms, so taking them at the same time as antibiotics can decrease how well the probiotics work. The solution is simple: space them apart.
Your doctor or pharmacist can help you time them correctly so the antibiotic does its job and the probiotic survives to do its job.
We could not check the other two ingredients — Lactobacillus casei Lc-11 and Lactobacillus rhamnosus Lr-32 — because we hold no interaction data for them. Use the medication checker below to look up your exact drugs, and talk with your doctor or pharmacist before starting this supplement.

For each ingredient in Gastro Flora with known interactions, here are the types of medications they can affect. Open any type for the detail — or search your exact drug in the checker above.
Lactobacillus acidophilus La-14
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.
Bifidobacterium longum Bl-05
Antibiotic Drugs
Theoretically, taking Bifidobacterium longum with antibiotic drugs might decrease the effectiveness of B. longum.
Since B. longum preparations usually contain live and active organisms, simultaneously taking antibiotics might kill a significant number of the organisms. Tell patients to separate administration of antibiotics and B. longum preparations by at least 2 hours.
