摘要

The present invention relates to a collagen hydrolyzate produced by enzymatic hydrolysis of type B bone gelatin, wherein the collagen hydrolyzate is formed from peptides of which at least 50% by weight, especially at least 70% by weight, have a molecular weight of 1500 to 3500 Da, and which have a mean molecular weight in the range from 4000 to 8000 Da, especially in the range from 4500 to 6000 Da. The invention further relates to the use of this collagen hydrolyzate as active ingredient to maintain and/or improve the health of the bones, especially for prevention and/or treatment of osteoporosis. The invention further relates to a food supplement comprising the collagen hydrolyzate.
