Magnetic bead-assisted extraction combined with ID-LC-MS/MS for simultaneous quantification of fat-soluble vitamins A, D, E, and K in human serum

Puntos clave

• Fat-soluble vitamins A, D, E, and K were effectively quantified using the method employed, enhancing measurement precision.
• The analysis demonstrated a 95% accuracy rate in vitamin levels across multiple serum samples.
• This study uses magnetic bead-assisted extraction paired with ID-LC-MS/MS for vitamin measurement.
• Highlighting nutritional assessments could benefit from improved methodologies for vitamin analysis.
