Felicia Newell, MScAHN, RD

Registered Dietitian, Nutritionist and Nutrition Consultant

Felicia is a Registered Dietitian with over fifteen years of experience in nutrition research, clinical care, private practice consulting, and nutraceutical formulation review. With a Master’s in Applied Human Nutrition, she bridges nutrition science and pharmacology—focusing on ingredient-function relationships, bioavailability, metabolic signaling, and consumer safety.

Felicia collaborates with health brands, product developers, and regulatory teams to evaluate formulation efficacy, optimize nutrient dosing, assess nutrient–drug and herb–drug interactions, and translate complex science into credible, consumer-friendly content. Her expertise in pharmacokinetics and pharmacodynamics informs her evaluation of how nutrients, adaptogens, botanicals, amino acids, and micronutrients influence hormonal balance, energy metabolism, and overall physiological resilience.

Her career spans public health, chronic disease prevention, digestive and clinical nutrition, and sports and performance nutrition. As owner of Sustain Nutrition and a consultant and media contributor, Felicia supports evidence-based communication on topics like hormone balance, cortisol regulation, and nutraceutical science.

Guided by integrity, transparency, and sustainability, she partners with brands committed to scientific rigor, responsible product formulation, and improving public health through credible, evidence-based innovation.
