HelloPharmacist Scorecard of Clear Nails Plus Max by Justified Laboratories

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

Clear Nails Plus Max contains six active ingredients, all probiotics and a prebiotic: three Lactobacillus species (paracasei, plantarum, and acidophilus), a Bifidobacterium species, fructooligosaccharide (a carbohydrate that feeds beneficial bacteria), and a proprietary blend of additional probiotic bacteria labeled MAKTREK. These are live-culture supplements meant to support your gut.

The product also contains three inactive ingredients — cellulose, rice maltodextrin, and L-leucine — which are fillers and carriers.

Does it work?

Couldn't assess
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 assessable

We hold no graded evidence for this product's ingredients for its stated purpose.

Why this rating?
  • The label markets this product for: Advanced nail health support.
  • Our graded evidence for these ingredients doesn't cover that particular purpose.

The evidence for Lactobacillus acidophilus — one of the three Lactobacillus strains in this product — shows it is possibly effective for irritable bowel syndrome, Helicobacter pylori infection, antibiotic-associated diarrhea, and bacterial vaginosis. It's rated possibly ineffective for atopic disease, and we don't have enough reliable evidence to rate it for acute respiratory distress syndrome.

Fructooligosaccharide, the prebiotic in the blend, has insufficient evidence for osteoporosis, constipation, diabetes, travelers' diarrhea, and high cholesterol. We don't hold effectiveness data for the other probiotic strains in this product.

The evidence, ingredient by ingredient Lactobacillus Acidophilus Fructo-oligosaccharides (fos)

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 generally well tolerated in healthy adults and children. Gastrointestinal side effects — epigastric discomfort, abdominal pain, indigestion, gas, bloating, diarrhea, vomiting, and burping — can occur when you combine probiotics, but they're uncommon.

One trial reported two cases of rash and one of itching, though it's unclear whether L. acidophilus or another ingredient was responsible. Rarely, L. acidophilus has been isolated in serious infections like bacteremia and sepsis, though this typically happens in patients whose natural bacteria move to other parts of the body.

Fructooligosaccharide commonly causes abdominal pain, bloating, and gas, especially at higher doses, but a meta-analysis of eight trials found no increase in these symptoms at doses under 15 grams daily. Safety data for supplement-level doses of fructooligosaccharide are limited.

No pregnancy or breastfeeding data are on file for any ingredient.

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 2 matched ingredients can interact with medications — Lactobacillus Acidophilus.
  • 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.

Antibiotic drugs are the main medication type to double-check before using this product. Antibiotics can reduce the effectiveness of the live Lactobacillus acidophilus in this supplement.

Try to separate doses by a few hours, or let your pharmacist know you're taking both. Use the medication search tool on this page to verify your exact prescriptions.

The bottom line

Scorecard at a glanceFormula with limited ingredient disclosure with no assessable stated purpose. Moderate medication interactions have been identified, and safety information is well characterized.

This is a probiotic-prebiotic blend aimed at gut health. It's generally well tolerated, but gas and bloating are common, especially when you first start.

If you take antibiotics, space them out from this supplement — antibiotics can kill the live cultures and make the product less effective. Talk to your pharmacist about your specific medications before you start.

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.

Clear Nails Plus Max by Justified Laboratories: Common Questions

Does Clear Nails Plus Max by Justified Laboratories interact with any medications?
Yes. Based on its ingredients, Clear Nails Plus Max 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?
Clear Nails Plus Max contains 6 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.
Will this product work if I'm on antibiotics?
Antibiotics can kill the live probiotic organisms in this product, which may make it less effective. It's best to separate your antibiotic dose and this supplement by a few hours. Talk to your pharmacist about the timing that works for your specific antibiotic.
What side effects should I expect?
Gas, bloating, and abdominal pain are the most common side effects, especially when you first start. These are usually mild and often go away. Nausea, diarrhea, and burping can also happen, but they're less frequent. If side effects don't improve in a few days, check with your pharmacist.
Is it safe to take this if I have a weakened immune system?
We don't have specific safety data for people with weakened immunity. Although Lactobacillus acidophilus is generally well tolerated in healthy people, very rare serious infections have been reported. You should check with your doctor before starting, especially if your immune system isn't working normally.
Can I take this while pregnant or breastfeeding?
We don't have pregnancy or breastfeeding safety data on file for any of the ingredients in this product. Talk with your doctor or pharmacist about whether it's right for you during pregnancy or while nursing — they can weigh your individual situation.
Why does this product include fructooligosaccharide (FOS)?
Fructooligosaccharide is a prebiotic, meaning it acts as food for the beneficial bacteria in the product. It helps the probiotics survive and thrive in your gut. However, it can also cause gas and bloating on its own, especially at higher doses.
