HelloPharmacist Scorecard of Ultimate Flora RTX Daily Probiotic by Renew Life

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 10 active ingredients.
  • “Ultimate Flora Daily Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

This probiotic contains 10 ingredients, of which the active ones are the live bacterial strains: L. acidophilus, L. salivarius, L. paracasei, B. breve, L. casei, L. brevis, L. rhamnosus, L. plantarum, B. lactis (two strains), and a blend labeled Ultimate Flora Daily Blend. These are probiotics—beneficial bacteria meant to support your gut health.

The capsule itself is made from vegetable material, with cellulose as a filler.

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: Supports natural defenses and digestive health.
  • We looked for evidence on: Antibiotic-associated diarrhea, Bacterial vaginosis, Colic, Clostridioides difficile infection, 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).

L. acidophilus appears possibly effective for irritable bowel syndrome (IBS), Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis, based on the evidence we have on file. B. breve, by contrast, doesn't have clear evidence backing it for the conditions listed—it's rated either possibly ineffective or having insufficient evidence.

For the other strains in this product (L. salivarius, L. paracasei, L. casei, L. brevis, L. rhamnosus, and L. plantarum), we don't hold effectiveness ratings.

The evidence, ingredient by ingredient Lactobacillus Acidophilus Bifidobacterium Breve

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 2 of the 2 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 2 of 2.
  • General safety write-ups exist for 2 of 2.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

L. acidophilus is generally well tolerated in healthy adults and children, though you should check with your doctor before starting it. Gastrointestinal side effects like bloating, flatulence, abdominal pain, and diarrhea can occur when taking L. acidophilus with other probiotics, but they're uncommon.

B. breve is also generally well tolerated in healthy people, but it needs caution in those who are very ill or immunocompromised; limited safety data exist, so talk to your healthcare provider before use. In rare cases, both L. acidophilus and B. breve have been linked to serious infections (bacteremia and abscess) in vulnerable patients, though most cases appear tied to bacteria that were already present in the body.

Side effects, ingredient by ingredient Lactobacillus Acidophilus Bifidobacterium Breve

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?
  • 2 of the 2 matched ingredients can interact with medications — Lactobacillus Acidophilus, Bifidobacterium Breve.
  • 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 your antibiotic medications before taking this product. L. acidophilus and B. breve can be killed by antibiotics taken simultaneously, reducing the probiotic's effectiveness.

Space them out by at least a few hours. We couldn't check several other bacterial strains in this formula for interactions, so run your full medication list through the checker below.

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 if you have IBS, antibiotic-associated diarrhea, or certain other digestive concerns, though evidence for some strains is limited. If you take antibiotics, separate them from this product by a few hours—the antibiotic can kill the live bacteria in the capsule.

Talk to your pharmacist before starting, especially if you're very ill, immunocompromised, or pregnant.

L. acidophilus1 drug type · 182 drugs

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.

Ultimate Flora RTX Daily Probiotic by Renew Life: Common Questions

Does Ultimate Flora RTX Daily Probiotic by Renew Life interact with any medications?
Yes. Based on its ingredients, Ultimate Flora RTX Daily 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?
Ultimate Flora RTX Daily Probiotic contains 10 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 probiotic while I'm on antibiotics?
Not at the same time. Antibiotics kill the live bacteria in this product, making it less effective. Separate them by a few hours—take your antibiotic in the morning and the probiotic in the evening, or as directed by your pharmacist.
What are probiotics supposed to do?
Probiotics are live beneficial bacteria that may support your gut health. This product is labeled possibly effective for irritable bowel syndrome, antibiotic-associated diarrhea, bacterial vaginosis, and Helicobacter pylori infection, though evidence varies by strain.
Could this cause side effects?
Most people tolerate it well, but some experience mild gastrointestinal discomfort—bloating, gas, abdominal pain, or diarrhea—especially when first starting. These are uncommon. Rarely, in vulnerable patients, probiotics have caused serious infections, so talk to your doctor if you're very ill or immunocompromised.
Is it safe if I'm pregnant or nursing?
We don't have safety data on file for L. acidophilus or most of the other strains in pregnancy and lactation. Talk to your doctor or pharmacist before taking this product if you're pregnant or nursing.
How many live bacteria strains are in this?
This product contains 10 active ingredients—all live bacterial strains. Some we have good evidence for (like L. acidophilus), and others we have less data on. The exact CFU (bacterial count) should be on the label.
