L-Methionine is provided here as a pure sulfur-containing amino acid precursor for keratin synthesis. As the primary protein component of nails, keratin requires adequate sulfur donor molecules like Methionine for strong disulfide bond formation.

This single-ingredient approach is efficient for providing the structural building blocks needed for nail plate rigidity. However, it lacks the Biotin and Silicon cofactors needed for growth speed and cross-linking density.
