23 Nutrition Therapy

23 Nutrition Therapy is a Berkeley-based nutrition practice led by registered dietitian nutritionist Gayatri. The practice uses a functional medicine approach informed by the Kalish Method to look beyond isolated symptoms and address underlying stressors connected to concerns such as brain fog, fatigue, digestive issues, hormone imbalance, gut health, and detox support. Its care model combines clinical dietetics with functional nutrition, emphasizing nutrition as a therapeutic tool for restoring balance while also supporting long-term wellness through lifestyle, behavior, genetics, and longevity-informed habits. In addition to client care, the business includes The Functional Clinic Immersion Mentorship, founded in 2023 to train dietitians and dietetic interns in functional nutrition.
