I'm Dr. Erin Henderson, a licensed clinical psychologist. My background isn't in sales or marketing. It's in understanding how the mind and body interact, how research gets evaluated, and how to tell the difference between something that has real evidence behind it and something that simply sounds convincing.
The supplement industry is largely unregulated and heavily driven by marketing. As someone trained in evaluating empirical evidence, I focus on what actually works.
That's exactly the lens I bring to supplements. I created The Supplement Psychologist for people who want to make informed choices about what they put in their bodies.
Why retail platforms fall short
Online retail platforms are convenient, but convenience comes with a catch. Third-party supplement sellers operate with very little oversight — counterfeit products, mislabeled doses, and contaminated ingredients are well-documented problems.
When a product looks identical to the real thing but isn't — and you're taking it daily expecting a health benefit — that matters. Buying through a licensed practitioner on a professional platform removes that uncertainty entirely.
The Supplement Psychologist is powered by Fullscript -- What makes this platform different?
