HelloPharmacist Scorecard of TruBifido by Master Supplements

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 5 active ingredients.
  • “Proprietary Probiotic Blend” is a proprietary blend — the label gives one combined amount (130.64 mg) without saying how much of each component you get.

TruBifido contains five active ingredients, all probiotics—beneficial live bacteria. The two we have detailed data for are Bifidobacterium longum infantis and Bifidobacterium bifidum; the others are additional Bifidobacterium strains (Bi-07, HN019, and animalis lactis) grouped in a proprietary blend.

The inactive ingredients are cellulose, alginate, hydroxypropyl methylcellulose, gellan gum, water, phosphate, magnesium stearate, silicon dioxide, ascorbic acid, LactoStim, and calcium silicate—these are binders, fillers, and capsule materials.

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 and immune health support.
  • We looked for evidence on: Antibiotic-associated diarrhea, Colic, Clostridioides difficile infection, Common cold, Constipation, Exercise-induced respiratory infections — and 4 related terms.
  • The strongest evidence on file: Bifidobacterium Bifidum is rated "Possibly Effective" for Irritable bowel syndrome (IBS) (Natural Medicines).
  • Also on file: Bifidobacterium Breve is rated "Insufficient Reliable Evidence To Rate" for Antibiotic-associated diarrhea, Constipation, Irritable bowel syndrome (IBS), Necrotizing enterocolitis (NEC), and more.

Evidence for this product is mixed and limited. Bifidobacterium bifidum shows possibly effective ratings for irritable bowel syndrome and respiratory tract infections, but evidence is insufficient to rate its use for hay fever, Alzheimer disease, or anxiety.

Bifidobacterium longum infantis is rated possibly ineffective for age-related cognitive decline and sepsis, and we have insufficient evidence for hay fever, antibiotic-associated diarrhea, and atopic disease. For most of the conditions these strains might target, the research just isn't there yet.

The evidence, ingredient by ingredient Bifidobacterium Breve Bifidobacterium Bifidum

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.

Both checked Bifidobacterium strains are generally well tolerated in healthy people, but caution is warranted if you're very ill or immunocompromised—there are rare reports of these bacteria entering the bloodstream in critically ill patients, including infants in intensive care. Bloating and flatulence are known side effects of probiotics in general, though they haven't been specifically reported for these strains.

Safety data overall are limited, so check with your doctor or pharmacist before starting, especially if you have a weakened immune system. We have no pregnancy or breastfeeding safety data on file for these ingredients.

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 — Bifidobacterium Breve, Bifidobacterium Bifidum.
  • 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.

Before taking TruBifido, check with your pharmacist if you're on any antibiotic drugs—these can kill off the live bacteria in this supplement if taken at the same time. Space doses a few hours apart to protect the product's effectiveness.

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.

TruBifido is a multispecies probiotic aimed at digestive and immune support. If you take antibiotics, you'll need to separate doses from this product to keep it effective.

Antibiotic Drugs

Theoretically, taking Bifidobacterium breve with antibiotic drugs might decrease the effectiveness of B. breve.
Since B. breve 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. breve preparations by at least 2 hours.

TruBifido by Master Supplements: Common Questions

Does TruBifido by Master Supplements interact with any medications?
Yes. Based on its ingredients, TruBifido 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?
TruBifido contains 5 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 TruBifido while I'm on an antibiotic?
You can, but timing matters. Since antibiotics kill bacteria—including the beneficial ones in this supplement—take them a few hours apart. Your pharmacist can help you schedule them so the probiotic stays effective. Always let them know you're using both.
What does each ingredient in TruBifido do?
The active ingredients are all Bifidobacterium strains, a type of probiotic (beneficial live bacteria) thought to support gut and immune health. Two of them—longum infantis and bifidum—have some research behind them for conditions like IBS and respiratory infections, though the evidence is limited for most uses.
Is TruBifido safe if I have a weak immune system?
Caution is needed. While these probiotics are generally well tolerated in healthy people, there are rare reports of Bifidobacterium bacteria entering the bloodstream in critically ill patients. Talk to your doctor before taking it if your immune system is compromised.
Will TruBifido give me gas or bloating?
Bloating and flatulence have been reported with probiotics in general, though they haven't been specifically reported from these Bifidobacterium strains. Start with a low dose and increase gradually to see how your stomach responds.
Can I take TruBifido if I'm pregnant or breastfeeding?
We don't have safety data on file for these specific ingredients during pregnancy or breastfeeding. Talk to your doctor or pharmacist for personalized guidance before you start.
