what is collagen peptides made of?

I think it’s really important to highlight the sustainability aspect here. When consumers ask what it’s made of, some get squeamish, but they shouldn’t.
Collagen peptide production is actually a fantastic example of upcycling. The raw materials (hides, bones, and scales) are by-products of the meat and fishing industries. Instead of these nutrient-dense parts going to waste, specialized facilities extract the protein to create high-value health supplements. If you are a brand owner, this is a great sustainability story to tell your customers.
