Our Final Verdict
NanoDefense Pro
NanoDefense Pro is a 15 mL water-based liquid labelled "foot microbiome support". Its label lists colloidal silver, turmeric and quercetin extracts, luteolin, chrysin, serratiopeptidase and cosmetic peptides — with no amounts — and carries the warning "The safety of this product has not been determined." The sales page contradicts that, saying every ingredient has been "proven to be safe in clinical trials", and names an enzyme (deoxyribonuclease) that is not on the label. None of the ingredients has a human trial against nail fungus. For a confirmed fungal nail infection the evidence points to prescription treatment: oral terbinafine, or topical efinaconazole 10%.
