17B CFU

Probiotic Strength

Why Kerabiotics Outperforms Topical Antifungals

Topicals treat the surface. Kerabiotics addresses the systemic microbiome factors that cause nail fungus to keep coming back.

🦠

Probiotic Nail Microbiome

3 clinically studied probiotic strains (17B CFU) target the gut-nail axis — the systemic root cause of recurrent fungal infections that topicals can't reach.

🧪

Caprylic Acid Antifungal

300 mg of Caprylic Acid (C8 medium-chain fatty acid) directly disrupts Candida cell membranes in the gut and systemically throughout the body.

🌿

Quercetin + Tea Tree

Anti-inflammatory Quercetin combined with terpinen-4-ol from Tea Tree oil targets fungal organisms at multiple biological stages.

💊

Biotin 5,000 mcg

Clinical-dose biotin supports nail keratin synthesis — rebuilding the nail structural protein that fungal infection degrades over time.

How Kerabiotics Works — 3 Steps

A multi-mechanism approach that topicals and single-ingredient supplements cannot replicate.

1

Restore Gut Balance

Probiotic strains colonize the GI tract, reducing Candida overgrowth — the systemic reservoir that drives recurrent nail infections.

2

Block Fungal Activity

Caprylic Acid and Quercetin disrupt fungal cell membranes and block the enzymes fungi use to spread through nail tissue.

3

Rebuild Nail Tissue

Biotin (5,000 mcg) and Zinc (20 mg) provide the raw materials for healthy nail keratin to regrow and replace infected nail.

Margaret T.

Texas · Week 14

Tried two topicals and a prescription cream over two years — nothing lasted. With Kerabiotics, by week 10 I started seeing healthy pink nail growing from the base. By week 14 the difference is visible.

Florida · Week 20

The yellow discoloration on my big toenail for almost three years is almost completely gone at 20 weeks. The probiotic theory made sense to me and the results confirmed it.

California · Week 12

Nails look healthier and less brittle at 12 weeks. I'm giving 4 stars because the timeline is longer than I hoped — but I'm seeing real progress so continuing my 6-bottle order.

Healthy nail microbiome — understanding toenail fungus

What Is the Nail Microbiome and Why It Drives Fungal Infections

Like the gut, your nails host a community of microorganisms. In healthy people, beneficial bacteria occupy the nail space and suppress fungal overgrowth. When this balance breaks — through antibiotics, poor circulation, or gut dysbiosis — Trichophyton rubrum establishes infection.

This explains why topicals that address surface symptoms often fail long-term: they do not restore the microbiome balance that allowed the infection in the first place. Kerabiotics' probiotic approach targets this root cause.

Frequently Asked Questions

What is Kerabiotics? +
Kerabiotics is an oral probiotic supplement formulated to address toenail fungus from the inside. It combines 3 probiotic strains (17B CFU) with Caprylic Acid, Quercetin, Biotin, and Zinc to target the nail microbiome root cause of chronic fungal infections.
How long does Kerabiotics take to work? +
Most users see initial nail color and texture changes within 30–45 days. Full results for already-damaged nails require 90–180 days, as nails grow 1–2 mm per month and the infected portion must physically grow out.
