HelloPharmacist Scorecard of Ultimate Flora Immune Probiotic 25 Billion 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 12 active ingredients.
  • “Bifido Probiotic Blend” is a proprietary blend — the label doesn't break down how much of each component you get.
  • “Lacto Probiotic Blend” is a proprietary blend — the label doesn't break down how much of each component you get.
  • “Immune Probiotic Culture Blend” is a proprietary blend — the label gives one combined amount (77 mg) without saying how much of each component you get.

This product contains 12 active probiotic ingredients — living beneficial bacteria that support digestion and immune function. The two Lactobacillus acidophilus strains (NCFM and La-14) are the ones we have the most data on.

The rest are a mix of other Lactobacillus species (plantarum, rhamnosus, casei, brevis, paracasei), Bifidobacterium species (lactis, infantis), and Lactococcus lactis. These are grouped into three blends on the label: Bifido, Lacto, and Immune Probiotic Culture blends.

The inactive ingredients are microcrystalline cellulose (a filler), the capsule itself, and medium-chain triglycerides.

Does it work?

Not established
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
Not established

The graded evidence we hold for these ingredients covers different conditions than the ones this product is marketed for, so there's no established rating for its stated use — see Lactobacillus Acidophilus's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: supports respiratory and immune health.
  • We looked for evidence on: Allergic rhinitis (hay fever), Asthma, Respiratory tract infections, Common cold, Influenza, Immune function.
  • The closest evidence on file: Lactobacillus Acidophilus is rated "Insufficient Reliable Evidence To Rate" for Allergic rhinitis (hay fever) (Natural Medicines).
  • Also on file: Lactobacillus Acidophilus is rated "Insufficient Reliable Evidence To Rate" for Asthma, Respiratory tract infections.

For the Lactobacillus acidophilus strains we have data on, the evidence shows they're possibly effective for irritable bowel syndrome (IBS), antibiotic-associated diarrhea, Helicobacter pylori infection, and bacterial vaginosis. They appear possibly ineffective for atopic disease, and there isn't enough reliable evidence yet to rate them for acute respiratory distress syndrome.

We don't have effectiveness ratings for the other nine probiotic strains in this blend.

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. Mild gastrointestinal side effects like stomach discomfort, bloating, gas, or diarrhea are uncommon but can occur when taking probiotics, especially in combination.

In rare cases, the live organisms have caused serious infections (bacteremia, sepsis, endocarditis) — but these almost always happened in people with weakened immune systems or serious underlying illness, not healthy people. There's no safety data on file for use during pregnancy or breastfeeding, so talk with your doctor or pharmacist if you're pregnant or nursing.

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.

Antibiotics are the main medication type to watch with this product. Taking them at the same time as these probiotics can reduce how well the probiotics work.

Separate them by several hours — your pharmacist can help you time them right. For the other nine probiotic strains in this blend, we hold no interaction data, so run your full medication list through the checker below.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no established evidence rating for its marketed use. Moderate medication interactions have been identified, and safety information is well characterized.

This probiotic is a solid choice if you have IBS, need support after antibiotics, or want general digestive health — especially if you tolerate live probiotics well. If you take antibiotics, separate them from this product by a few hours.

Check your medications below before starting, and talk to your pharmacist if you have a weakened immune system or serious underlying illness.

Ultimate Flora Immune Probiotic 25 Billion by Renew Life: Common Questions

Does Ultimate Flora Immune Probiotic 25 Billion by Renew Life interact with any medications?
Yes. Based on its ingredients, Ultimate Flora Immune Probiotic 25 Billion 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 Immune Probiotic 25 Billion 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 my antibiotic?
Not at the same time. Antibiotics kill the live bacteria in probiotics, so you won't get the probiotic benefit. Take your antibiotic dose, then wait a few hours before taking this product, or take the probiotic first and wait before your antibiotic. Ask your pharmacist for the best timing for your specific antibiotic.
What does this probiotic actually do?
The Lactobacillus acidophilus strains are possibly effective for irritable bowel syndrome, antibiotic-associated diarrhea, Helicobacter pylori infection, and bacterial vaginosis. We don't have solid evidence for the other strains in the blend, though they're generally considered supportive for digestive and immune health.
Will it cause side effects?
Most people tolerate it well, but some get mild stomach discomfort, bloating, gas, or diarrhea — these are uncommon. In very rare cases, the live organisms have caused serious infections, but only in people with weakened immune systems. If you have a serious illness or weak immunity, check with your doctor first.
Is it safe if I'm pregnant or breastfeeding?
We don't have safety data on file for pregnancy or breastfeeding with this product. Talk with your doctor or pharmacist — they can help you decide if it's right for you.
Why are there so many different bacteria in one capsule?
Different probiotic strains have different roles in your gut and immune system. By combining them, the product aims to cover more ground for digestive and immune support — though we have stronger evidence for some strains than others.
Does it have fillers?
Yes — microcrystalline cellulose (a common filler), the capsule, and medium-chain triglycerides. These are all inactive ingredients; the live bacteria are the active part.
