In the past, collagen was often part of the nutrition: by bone brewing, skin, cartilage or offal, collagen were regularly taken into account, all parts of an animal were used (today it is called "from nose to tail"). Today we eat industrially processed foods that contain far fewer nutrients. Even low -fat foods are often preferred, at the same time it has been a trend for a long time to consume only the best parts. A high -quality collagen powder compensates for these defects. Additional taking collagen is therefore a sensible addition to modern nutrition.
