Integrative medical practice and naturopathic wellness center at 5639 La Jolla Blvd, La Jolla, CA 92037, in the Bird Rock neighborhood. KOI Wellbeing staffs a team of MDs, nurse practitioners, and naturopathic doctors who collaborate on gut health protocols, bioidentical and pellet hormone replacement therapy, specialty lab testing, Morpheus8 radiofrequency microneedling, hair restoration, Xeomin injections, and custom IV infusion therapy with preservative-free, made-to-order nutrient blends. The naturopathic-plus-aesthetic dual track goes deeper than the IV-and-injectable model at RTW Health Services on Girard Avenue, which does not offer naturopathic consultations or gut-focused functional lab work. KOI also employs a registered dietitian nutritionist for functional nutrition coaching — rare among La Jolla wellness practices. A second location operates in Sorrento Valley. Open Monday through Friday 8am–5pm, Saturday 8am–4pm. SD Bombshell Aesthetics at 5726 La Jolla Blvd handles injectable aesthetics for Bird Rock clients who separate their hormone therapy from their cosmetic filler provider.
