Two common production techniques for bioactive peptides are enzymatic hydrolysis and microbial fermentation , which are both ways to break proteins down into smaller peptides or individual amino acids.12 The realm of bioactive peptides is somewhat limited because, remember, peptides can easily break down in the digestive tract, and many are too molecularly large to permeate the skin or intestinal lining.5 But there are several peptide varieties that are readily bioavailable by oral or transcutaneous administration, such as collagen and GHK-Cu
