ImpactNeutral impact

While there is recognition of the article's relevance, the discussions mainly serve to highlight potential but unconfirmed benefits rather than prescribing immediate changes in practice.

Abstract in brief

Dietary supplements like zinc, biotin, vitamin D, nicotinamide, and Polypodium are often recommended in dermatology for skin, hair, and nail issues, but current evidence supporting their safety and effectiveness is limited.
Most existing studies lack standardized dosing, consistent outcome measures, and comprehensive reporting on side effects, making it difficult to compare results across different research.
The strongest evidence supports nicotinamide for preventing nonmelanoma skin cancers, while there is some potential for vitamin D and Polypodium in reducing melanoma risk and providing photoprotection; however, more high-quality studies are needed before these supplements can be widely endorsed.]
