What Is a Peptide, and How Does It Work?

A peptide is a chain of amino acids that function primarily as signaling molecules. They carry messages between cells, influencing downstream processes in ways that are both targeted and far-reaching. 

For example, GLP-1 peptides act as hormone signals that tell the body to shift several systems at once. The “message” is essentially: regulate appetite, improve blood sugar control, and slow nutrient intake, with downstream effects that can indirectly help with menopausal symptoms. 

Peptides are distinct from hormones, though the two categories overlap.  Some peptides are hormones, and some hormones are peptides, which is part of what makes the category feel confusing from the outside. The important thing to understand is that peptides are cellular messengers, and that they operate at the mitochondrial level in ways that make them pharmacologically meaningful.

Peptide therapy can be a wonderful adjunct to integrative midlife health optimization. While I don't directly prescribe them, I can provide guidance on how to create a well-managed peptide protocol that doesn't just provide a prescription but provides clinician guidance along with the additional integrative strategies such as nutrition & mindful movement, to ensure success.
