HelloPharmacist Scorecard of Ultra Pro-20 by Ultra6 Nutrition

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 1 of its 21 active ingredients.
  • “Proprietary Probiotic Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

Ultra Pro-20 contains 21 ingredients, of which 15 are live probiotic strains — bacteria and one yeast — that are intended to support digestive and immune health. The checked strains include several Lactobacillus species (L. acidophilus, L. gasseri, L. bulgaricus, L. helveticus), multiple Bifidobacterium species (B. breve, B. bifidum, B. longum), Streptococcus thermophilus, Bacillus subtilis, and Saccharomyces boulardii, a beneficial yeast.

The product also contains prebiotic fructooligosaccharides (a carbohydrate that feeds beneficial bacteria) and six inactive ingredients: purified water, stevia, natural flavor, potassium sorbate, and citric acid.

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: probiotic support for digestive and gut health.
  • We looked for evidence on: Antibiotic-associated diarrhea, Clostridioides difficile infection, Constipation, Crohn disease, Colic, Diarrhea — and 3 related terms.
  • The strongest evidence on file: Saccharomyces Boulardii is rated "Possibly Effective" for Antibiotic-associated diarrhea (Natural Medicines).
  • Also on file: Saccharomyces Boulardii is rated "Possibly Effective" for Rotaviral diarrhea, Travelers' diarrhea, Clostridioides difficile infection.
  • Also on file: Lactobacillus Acidophilus is rated "Possibly Effective" for Antibiotic-associated diarrhea.

The evidence for most of these strains is still emerging. L. acidophilus and B. bifidum show possibly effective evidence for irritable bowel syndrome (IBS), and L. acidophilus is possibly effective for antibiotic-associated diarrhea and bacterial vaginosis.

B. longum has insufficient evidence for the conditions listed in our data. S. boulardii stands out with strong possibly effective ratings for travelers' diarrhea, antibiotic-associated diarrhea, and rotaviral diarrhea.

For many other uses — allergic rhinitis, anxiety, asthma, cognitive function — the evidence we hold rates as insufficient. The product has not been studied as a whole, so effectiveness depends on the individual strains and the dose.

The evidence, ingredient by ingredient Lactobacillus Acidophilus Bifidobacterium Breve Bifidobacterium Bifidum Bifidobacterium Longum Streptococcus Thermophilus Brewer's Yeast Lactobacillus Gasseri Lactobacillus Delbrueckii

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 11 of the 11 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 11 of 11.
  • General safety write-ups exist for 11 of 11.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

Most of these probiotic strains are generally well tolerated in healthy adults and children. However, live microorganisms do carry a small risk: rare cases of bacterial or fungal bloodstream infections (bacteremia, sepsis) have been reported, especially in critically ill patients, those with weakened immune systems, or people with central lines or catheters.

Gastrointestinal side effects — bloating, flatulence, abdominal discomfort, and diarrhea — are uncommon but can occur. One trial reported a rash with itching in a small number of participants, though it's unclear whether the probiotics were responsible.

We hold no pregnancy or breastfeeding data for most of these strains; B. longum is rated possibly safe in pregnancy. Because safety data are limited, talk with your doctor before use if you are very ill, immunocompromised, or pregnant.

Meds to double-check

Major interaction found
Known Interaction Concern · database check
Major identified

At least one ingredient has a documented Major-severity interaction. Check your medications for a personalized result.

Why this rating?
  • 10 of the 11 matched ingredients can interact with medications — Saccharomyces Boulardii, Brewer's Yeast, Lactobacillus Acidophilus, Bifidobacterium Breve, Bifidobacterium Bifidum, among others.
  • The most serious interaction on file is rated Major.
  • Some involve high-stakes drug classes: diabetes medications; lithium.
  • For scale: 318 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.

Separate antibiotic drugs from Ultra Pro-20 by at least 2–3 hours — antibiotics will kill the beneficial bacteria in the product and reduce its effectiveness. Antifungal medications can similarly reduce the viability of the S. boulardii yeast in this product.

If you are on any antibiotic or antifungal, run it through the medication checker on this page or ask your pharmacist before taking this supplement.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence for its stated purpose. Major medication interactions have been identified, and safety information is well characterized.

Ultra Pro-20 is a multi-strain probiotic designed to support digestive health, with the strongest evidence for S. boulardii in traveler's and antibiotic-associated diarrhea. If you take antibiotics or antifungals, space them several hours away from this product to preserve its effectiveness.

Avoid this product if you are critically ill or severely immunocompromised. Talk with your pharmacist before starting, especially if you're on other medications.

Ultra Pro-20 by Ultra6 Nutrition: Common Questions

Does Ultra Pro-20 by Ultra6 Nutrition interact with any medications?
Yes. Based on its ingredients, Ultra Pro-20 has a known interaction with 318 medications, including 9 rated major. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Ultra Pro-20 contains 21 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'd lose the benefit. Separate them by at least 2–3 hours — take your antibiotic at one time of day and this product at another. Your pharmacist can help you plan the timing.
What is S. boulardii and why is it in here?
S. boulardii is a beneficial yeast strain (not a bacterium) with good evidence for traveler's diarrhea, antibiotic-associated diarrhea, and rotaviral diarrhea. Avoid it at the same time as antifungal drugs, which can kill it.
Is this safe if I'm pregnant or breastfeeding?
We have limited pregnancy and breastfeeding data for most of these strains. B. longum is rated possibly safe in pregnancy, but for the others, the evidence just isn't there. Talk with your doctor or pharmacist before taking it while pregnant or nursing.
Can this cause side effects?
Most people tolerate it well. Bloating, flatulence, and mild abdominal discomfort can occur, though these are uncommon. In rare cases, a rash has been reported. If you're very ill or have a weakened immune system, ask your doctor first — there is a small risk of serious infections with live probiotics.
Does this product work?
S. boulardii has good evidence for traveler's diarrhea and antibiotic-associated diarrhea. L. acidophilus and B. bifidum show possibly effective evidence for IBS and antibiotic-associated diarrhea. For many other uses, the evidence is still unclear or insufficient.
What if I can't take this for some reason?
There are other probiotic products with different strains, and some foods like yogurt and fermented vegetables contain probiotics naturally. Ask your pharmacist about alternatives that suit your situation.
