Abstract:
1. A collagen hydrolysate for use to improve the health of human skin, hair and/or nails, wherein the collagen hydrolysate is derived from mammals or poultry, wherein the collagen hydrolysate is produced by the consecutive action of at least two metalloproteases and/or serine proteases with a different specificity, wherein at least 90% by weight of the collagen hydrolysate has a molecular weight of less than 3,500 Da, wherein the collagen hydrolysate comprises at least four characteristic peptides with a molecular weight between 600 and 1,200 Da, and wherein the at least four characteristic peptides, in a molecular weight distribution determined by MALDI mass spectroscopy, have an intensity of at least twice the intensity of their surroundings, the MALDI mass spectroscopy being carried out by adjusting a sample of the collagen hydrolysate in 0.1% trifluoroacetic acid to a final concentration of 10 μg/μl, purifying the adjusted sample using μC
