HelloPharmacist Scorecard of Ther-Biotic Synbiotic by Klaire Labs

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 Oct 8, 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 8 active ingredients.
  • “Probiotic Blend” is a proprietary blend — the label gives one combined amount (323 mg) without saying how much of each component you get.

The product lists eight ingredients. The active probiotic strains include Lactobacillus acidophilus DDS-1, Bifidobacterium bifidum UABb-10, Lactobacillus rhamnosus GG, Lactobacillus plantarum UALp-05, Bifidobacterium animalis lactis UABla-12, Lactobacillus reuteri UALre-16, and Lactobacillus paracasei UALpc-04.

Sunfiber is also listed, along with a probiotic blend container whose component ingredients are listed individually. The inactive ingredients are hydroxypropyl methylcellulose, gellan gum, water, silica, and ascorbyl palmitate.

These are the non-active materials used in the capsule and formulation.

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

This product doesn't appear to be marketed for a specific use, so we graded its ingredients' overall clinical evidence instead.

Moderate

Some clinical evidence supports its ingredients for:

Why this rating?
  • We looked at the product name, claims, and label statements and couldn't find a stated purpose to grade.
  • Since the label doesn't commit to one use, we graded the ingredients' overall clinical evidence instead.
  • On file: Antibiotic-associated diarrhea — rated "Possibly Effective" (Lactobacillus Acidophilus) (Natural Medicines).
  • On file: Bacterial vaginosis — rated "Possibly Effective" (Lactobacillus Acidophilus) (Natural Medicines).
  • On file: Helicobacter pylori — rated "Possibly Effective" (Lactobacillus Acidophilus) (Natural Medicines).
  • On file: Irritable bowel syndrome (IBS) — rated "Possibly Effective" (Lactobacillus Acidophilus) (Natural Medicines).
  • On file: Respiratory tract infections — rated "Possibly Effective" (Bifidobacterium Bifidum) (Natural Medicines).

For Lactobacillus acidophilus DDS-1, the evidence is rated possibly effective for Helicobacter pylori, bacterial vaginosis, antibiotic-associated diarrhea, and irritable bowel syndrome (IBS). It is rated possibly ineffective for atopic disease and has insufficient reliable evidence to rate for allergic rhinitis (hay fever).

For Bifidobacterium bifidum UABb-10, the evidence is rated possibly effective for IBS and respiratory tract infections. It has insufficient reliable evidence to rate for allergic rhinitis, acute respiratory distress syndrome (ARDS), and age-related cognitive decline.

We hold no effectiveness ratings for the other ingredients.

The evidence, ingredient by ingredient Lactobacillus Acidophilus 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.

Lactobacillus acidophilus is described as generally well tolerated in healthy adults and children, though the data also notes it should be checked with your doctor before use. Gastrointestinal side effects such as bloating, gas, and diarrhea are described as uncommon.

Rare serious infections, such as bloodstream infections, have been isolated in some patients, mostly when bacteria move from their usual location in the body. Bifidobacterium bifidum is generally well tolerated in healthy people, but those with weakened immune systems should be cautious.

Bloating and gas have been reported with probiotic use in general, not specifically with B. bifidum. Bifidobacterium sepsis has occurred in critically ill patients, but these cases are rare and none seem to be due to B. bifidum.

Side effects, ingredient by ingredient Lactobacillus Acidophilus Bifidobacterium Bifidum

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 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.

The main drug type to double-check is antibiotics, rated Moderate, because they may reduce the effectiveness of the live probiotic organisms. We hold no interaction data for the other ingredients we could not check, so please search your exact medications on this page and review them with your own doctor or pharmacist.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with some supporting evidence behind its ingredients' uses. Moderate medication interactions have been identified, and safety information is well characterized.

This product may be worth considering if you are looking at one of the areas where the evidence is rated possibly effective, such as IBS. If you take antibiotics, have a weakened immune system, or are critically ill, be more careful and talk it over first.

Please discuss it with your own doctor or pharmacist before starting, especially if you take any prescription medication.

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.
