HelloPharmacist Scorecard of Biothin Probiotic 10 Billion CFU by Dr. Mercola

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

Full disclosure
Ingredient Transparency · database check
Full

Every active ingredient lists its own amount on the label.

Why this rating?
  • The label discloses an exact amount for 1 of its 1 active ingredient.
  • No proprietary blends here — you can verify the dose of every single component.

Biothin Probiotic contains one active ingredient: Lactobacillus gasseri BNR17, a beneficial probiotic strain containing live microorganisms. The product also includes several inactive ingredients — microcrystalline cellulose, hydroxypropyl methylcellulose, gellan gum, fructooligosaccharides, ascorbyl palmitate, and silicon dioxide — which serve as capsule material, binders, and preservative support.

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 Gasseri's own graded uses on its monograph.

Why this rating?
  • The label markets this product for: Supports metabolic health.
  • We looked for evidence on: Obesity, Weight management, Metabolic syndrome, Body composition.
  • The closest evidence on file: Lactobacillus Gasseri is rated "Insufficient Reliable Evidence To Rate" for Obesity (Natural Medicines).

The evidence for Lactobacillus gasseri is not established in our data. We hold insufficient reliable evidence to rate it for allergic rhinitis (hay fever), aspirin-associated stomach damage, asthma, bacterial vaginosis, common cold, and diarrhea.

That doesn't mean it doesn't work for these conditions — it means the research we have isn't robust enough to call it effective. Talk with your doctor or pharmacist about what the current science actually supports for what you're hoping to address.

The evidence, ingredient by ingredient Lactobacillus Gasseri

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 gasseri is generally well tolerated in healthy adults, but the safety evidence is limited and incomplete. The product comes with a caution: not enough reliable safety data exists, so use it only under a doctor's guidance.

Because these are live, active microorganisms, there is a theoretical concern that in some patients — especially those with weakened immune systems or other risk factors — the bacteria could spread beyond the gut and cause infection. Cases of bacteremia, sepsis, endocarditis, and other serious infections involving lactobacilli have been reported in the medical literature, though these are thought to occur mainly when bacteria translocate from the mouth or other natural sites.

Pregnancy and lactation safety data are not on file for this ingredient.

Side effects, ingredient by ingredient Lactobacillus Gasseri

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 Gasseri.
  • 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.

Check with your pharmacist or doctor before taking this product if you use antibiotics. Timing matters: antibiotics can kill the live organisms in the probiotic and reduce its effectiveness.

Altogether, these interactions span 182 individual medications. Use the medication checker below to look up your exact drugs.

The bottom line

Scorecard at a glanceFully disclosed formula 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 single-strain formula that's generally tolerated well in healthy people, but the evidence for what it actually does is limited. If you take antibiotics, space out your doses.

Most importantly, talk with your doctor or pharmacist before starting — especially if you have a weakened immune system, recent surgery, or other risk factors — so they can make sure it's right for you.

Antibiotic Drugs

Theoretically, taking Lactobacillus gasseri with antibiotic drugs might decrease the effectiveness of L. gasseri.
Lactobacillus gasseri 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. gasseri preparations by at least two hours.

Biothin Probiotic 10 Billion CFU by Dr. Mercola: Common Questions

Does Biothin Probiotic 10 Billion CFU by Dr. Mercola interact with any medications?
Yes. Based on its ingredients, Biothin Probiotic 10 Billion CFU 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?
Biothin Probiotic 10 Billion CFU contains a single active ingredient, and that one ingredient can interact with many different medications on its own. We check it against each medication and show the mechanism 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.
What exactly is Lactobacillus gasseri BNR17?
It's a beneficial probiotic strain — a live microorganism — included in this product. Probiotics are intended to support gut health, though the evidence for what this particular strain actually does is not strong enough in our data to call it proven.
Can I take this with my antibiotics?
Not at the same time. Antibiotics can kill the live bacteria in the probiotic, making it less effective. Talk with your pharmacist about spacing — usually waiting until after your antibiotic course to start the probiotic works best.
Is this safe during pregnancy or while breastfeeding?
We don't have safety data on file for this ingredient during pregnancy or lactation. Talk with your doctor or midwife to see if it's right for you.
What side effects should I watch for?
Most people tolerate it well. The main theoretical concern is that in some patients — especially those with weakened immunity — the live bacteria could spread and cause infection, though this is rare. Tell your doctor right away if you develop signs of infection like fever, chills, or unusual symptoms after starting.
Does this actually work for diarrhea or colds?
We don't have enough reliable evidence to say it works for diarrhea, common cold, or the other conditions listed. The research just isn't there yet. Ask your pharmacist what the current science actually shows.
