Meet Katie Ernst, RD
Katie Ernst, RD is a Registered Dietitian with 18 years of experience in clinical and community nutrition. She founded RD Verify to help readers cut through supplement marketing and make more informed decisions about the products they are considering.
With a background in evidence-based nutrition care, Katie brings a practical, dietitian-led perspective to supplement reviews, GLP-1 nutrition support, gut health, fiber, protein, muscle preservation, and sustainable weight-management nutrition.
At RD Verify, her goal is simple: help you understand what a product actually offers, who it may be useful for, who should probably skip it, and whether the ingredient list, dose, cost, and claims make sense.
Professional Background

Her experience includes helping clients navigate weight management, GLP-1 support, digestive concerns, protein intake, fiber goals, supplement questions, and realistic habit change.
That clinical lens is what shapes RD Verify. Instead of repeating brand claims, Katie reviews supplements with a dietitian’s eye for ingredient quality, dosing, safety, practical use, and overall value.
