Kay Russell is the lead product researcher and supplement strategist for VitaminProGuide.com. A graduate of Indiana University, Kay has spent over a decade deconstructing nutritional labels and investigating the physiological impacts of natural compounds on metabolic health.
Kay’s approach is rooted in evidence-based wellness, focusing on separating clinical research from marketing hype. Whether she is testing the absorption rates of liquid tinctures or analyzing the purity of plant-based superfoods, her mission is to provide readers with first-hand experience and laboratory-backed insights.
When she isn’t deep-diving into NIH clinical trials, Kay can be found hiking the trails of the Midwest or experimenting with nutrient-dense, plant-based recipes in her kitchen.
