HelloPharmacist Scorecard of Probiotic Advantage Ultra 20 by Dr. David Williams

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 Sep 3, 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 11 active ingredients.
  • “Probiotic Blend” is a proprietary blend — the label doesn't break down how much of each component you get.

Probiotic Advantage Ultra 20 contains 11 active ingredients: a blend of beneficial bacteria — L. rhamnosus, L. acidophilus, B. infantis, B. longum, B. bifidum, B. lactis, L. paracasei, L. salivarius, L. plantarum, and L. gasseri — plus kiwi extract. These live probiotic strains are meant to support your gut and digestive health; kiwi adds additional digestive support.

The tablet also contains inactive ingredients like cellulose, pectin, guar gum, and turmeric to hold it together and aid delivery.

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: digestive health and probiotic balance.
  • We looked for evidence on: Antibiotic-associated diarrhea, Bacterial vaginosis, Celiac disease, Clostridioides difficile infection, Constipation, Diarrhea — 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, Helicobacter pylori, Irritable bowel syndrome (IBS).
  • Also on file: Bifidobacterium Bifidum is rated "Possibly Effective" for Irritable bowel syndrome (IBS).

The probiotics in this product show mixed evidence. L. acidophilus is possibly effective for irritable bowel syndrome (IBS), H. pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis.

B. bifidum is possibly effective for IBS and respiratory tract infections. B. longum and L. gasseri lack reliable evidence for most of the conditions studied — we list insufficient data for them.

Kiwi extract also shows insufficient evidence for asthma, constipation, high blood pressure, and IBS. If you're considering this product for a specific health goal, talk it over with your doctor or pharmacist to see if the evidence supports it for your situation.

The evidence, ingredient by ingredient Lactobacillus Acidophilus Bifidobacterium Longum Bifidobacterium Bifidum Lactobacillus Gasseri Kiwi

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 5 of the 5 matched ingredients.
  • Pregnancy & breastfeeding safety ratings cover 5 of 5.
  • General safety write-ups exist for 5 of 5.
  • Remember: this measures how much safety information exists. Thin data is not the same as being safe.

The probiotic strains in this product are generally well tolerated in healthy adults and children. However, caution is advised for people with weakened immune systems, serious illness, or those who are critically ill — rare cases of bacterial bloodstream infection (bacteremia) and sepsis have been reported in such patients.

Kiwi extract can trigger allergic reactions in some people, ranging from itching and swelling of the lips and mouth to severe reactions like anaphylaxis, especially in those with known kiwi allergy. Gastrointestinal side effects from the probiotics — like bloating, flatulence, abdominal discomfort, and diarrhea — are uncommon but can occur.

During pregnancy, L. acidophilus and B. bifidum are rated possibly safe, and kiwi is rated likely safe, but data are limited; B. longum and L. gasseri are rated possibly safe for both pregnancy and lactation. Because safety data vary by ingredient, confirm with your doctor or pharmacist before taking this product during pregnancy or while breastfeeding.

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?
  • 5 of the 5 matched ingredients can interact with medications — Lactobacillus Acidophilus, Kiwi, Bifidobacterium Bifidum, Bifidobacterium Longum, Lactobacillus Gasseri.
  • The most serious interaction on file is rated Moderate.
  • Some involve high-stakes drug classes: anticoagulant / antiplatelet drugs.
  • For scale: 470 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.

Before you take Probiotic Advantage Ultra 20, check with your doctor or pharmacist if you're on blood thinners or antiplatelet drugs (warfarin, aspirin, clopidogrel, heparin) — kiwi extract may increase bleeding risk. If you take blood pressure medications, confirm first, since kiwi can lower blood pressure further.

If you're on antibiotics, separate them from this product by several hours, because antibiotics may kill the live probiotics and make them less effective. Altogether, these interactions span 470 individual medications.

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 product may help with IBS, antibiotic-associated diarrhea, or related digestive concerns if the probiotics L. acidophilus or B. bifidum are effective for you — but the evidence is "possibly" rather than proven. If you're on blood thinners, blood pressure medications, or antibiotics, you'll need to check with your doctor or pharmacist first, because this product interacts with all three types.

Anyone with a weakened immune system or known kiwi allergy should also clear it with their healthcare provider before starting.

Kiwi extract2 drug types · 289 drugs

Anticoagulant/Antiplatelet Drugs

Clinical research suggests that kiwi inhibits platelet aggregation. Theoretically, kiwi might increase the risk of bleeding when used with antiplatelet or anticoagulant drugs. Some anticoagulant or antiplatelet drugs include aspirin, clopidogrel (Plavix), dalteparin (Fragmin), enoxaparin (Lovenox), heparin, ticlopidine (Ticlid), warfarin (Coumadin), and others.

Likelihood Possible Evidence D
Antihypertensive Drugs

Clinical research suggests that consuming kiwi reduces systolic and diastolic blood pressure in hypertensive individuals. Theoretically, concomitant use of kiwi and antihypertensive drugs may increase the risk of hypotension when used in combination with drugs that lower blood pressure. These include captopril (Capoten), enalapril (Vasotec), losartan (Cozaar), valsartan (Diovan), diltiazem (Cardizem), amlodipine (Norvasc), hydrochlorothiazide (HydroDiuril), furosemide (Lasix), and many others.

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.

Probiotic Advantage Ultra 20 by Dr. David Williams: Common Questions

Does Probiotic Advantage Ultra 20 by Dr. David Williams interact with any medications?
Yes. Based on its ingredients, Probiotic Advantage Ultra 20 has a known interaction with 470 medications. Use the checker to see how it interacts with a specific drug.
How can one product interact with so many drugs?
Probiotic Advantage Ultra 20 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 probiotic while I'm on antibiotics?
You can, but timing matters. The antibiotics might kill the live organisms in the probiotic, making it less effective. Talk to your pharmacist about spacing out the doses — typically several hours apart — so they don't work against each other.
Is this product safe during pregnancy?
Most of the probiotic strains in this product are rated possibly safe during pregnancy. Kiwi extract is rated likely safe. However, safety data are limited, so talk with your doctor or pharmacist before starting it during pregnancy to make sure it's right for you.
What if I'm allergic to kiwi?
You should avoid this product. Kiwi can trigger serious allergic reactions in some people, including swelling of the mouth and throat, rash, and in rare cases anaphylaxis. If you have a known kiwi allergy, do not take it.
Will this help my irritable bowel syndrome (IBS)?
L. acidophilus and B. bifidum, two of the strains in this product, are rated possibly effective for IBS. That means there's some evidence they might help, but it's not proven. Talk with your doctor about whether this product fits your IBS management plan.
Can I take this if I have a weakened immune system?
Caution is advised. Rare cases of serious bacterial bloodstream infections have been reported in critically ill or immune-compromised patients taking probiotics. Check with your doctor before starting this product if your immune system is compromised.
What are the common side effects?
Gastrointestinal side effects like bloating, flatulence, abdominal discomfort, and diarrhea can occur, but they're uncommon. Allergic reactions to kiwi — itching, swelling of the mouth or lips — are possible in sensitive people. Most healthy people tolerate it well.
