This HND piece examines the emerging world of peptide supplementation. We start with a bit of biochemistry—pointing out that bioactive peptides include many hormones, antibiotics, and other compounds that participate in the metabolic functions of living organisms. A prime example is insulin, well-known to diabetics as one of the few substances that can rapidly lower blood glucose levels.
In a few cases, topical use of peptides (including collagen) and oral supplementation (creatine) are well-established. However, there are dozens of other peptides out there that are the subject of research, as well as semi-legal use by the public. The good news is that bioactive peptides are very powerful; the bad news is that bioactive peptides are very powerful.
