The future of medicine holds immense promise for the therapeutic use of peptides across each medical specialty. Peptides are short chains of amino acids that serve as potent chemical messengers of the body. There are many varieties of peptides, each having a unique message to share and critical role to play in influencing the behavior of specific cells and tissues throughout each organ system. The potential of peptides to optimize energy metabolism and hormonal balance, strengthen the intelligence of the immune system, reduce inflammation, protect against infection, accelerate tissue healing and regeneration has been well demonstrated and will continue to be extensively researched. Our journey in understanding peptides is essential to the future of medicine because we are now using the bodies own communication system to heal itself and prevent/ reverse neurologic disorders, autoimmune disease, cardiovascular disease, gastrointestinal disease, hormonal imbalance, and much of what we have brushed off as the normal aging process. Currently, peptides are often used to heal injured tissues, reverse diabetes and obesity, regenerate mitochondria and promote energy, reduce inflammation, improve brain function, heal the stomach and gastrointestinal lining, reduce the burden of autoimmune disease and cancer.
