After dividing t the research subjects into control group(n=15), collagen group(n=15) of people taking collagen, enzyme group (n=15) of people taking enzyme, and complex group(n=15) of people taking them complexly, they were asked to take them in the morning and evening for total 12 weeks. After intake, the total content of amino acid in nails was increased by 6.4%(p<0.05) in the enzyme group, and by 7.1%(p<0.01) in the complex group. After intake, only the complex group showed the decrease of absorbance by 18.5%(p<0.001) for nail density,increase of nail thickness by 24.4%(p<0.001), and decrease of nail roughness by 25.4%(p<0.001).
