Peptides are everywhere right now and the questions I’m getting about them in clinic have never been higher.
So here’s my honest take as a Functional Medicine Practitioner and Nutritional Therapist.
Peptides are short chains of amino acids that signal different processes in the body and some of them have genuinely interesting therapeutic potential. But the way they’re being marketed right now, particularly GLP-1 analogues like semaglutide, is running well ahead of the nuance people actually need.
What concerns me most is that peptides are being used as a first response rather than a last resort, without addressing the underlying terrain that got someone there in the first place.
Gut health, blood sugar regulation, inflammation, sleep, stress physiology, these all need to be part of the picture. A peptide won’t fix a dysregulated nervous system or a microbiome that’s been depleted for years.
That doesn’t mean they have no place. It means they work best when the foundations are already being supported.
As always, context matters. Your biology is individual. And anything that acts as a powerful signal in the body deserves careful, informed consideration - not a trend-driven decision.
More on this to come. Save this if peptides are something you’re currently exploring or being offered.
