Practicing since 1990, Dr. Ingrid Fullerton operates Optimal Health Solution in Carlsbad at 701 Palomar Airport Road inside the Holistic Health Center near the Bressi Ranch business district. A Doctorate of Chiropractic paired with a Certification in Applied Clinical Nutrition from Southern California University of Health Sciences drives a dual-track model combining spinal correction with whole-food supplementation, a functional approach shared by the integrative medical team at NextMed North on the Palomar Airport Road corridor. Her Bachelor of Science in Human Biology from California State University, Long Beach and 14 years of competitive gymnastics inform an exercise-therapy methodology emphasizing joint stabilization and muscular balance. Microbiome testing, blood-chemistry panels, and allergy assessments supplement standard chiropractic intake, supporting a diagnostic process that coordinates with behavioral-health providers including Mindpath Health for patients whose chronic pain involves psychosomatic components. The practice's highest-complexity protocols pair kinesiological muscle testing with Standard Process whole-food supplement formulations to address nutrient deficiencies identified through serum 25-hydroxyvitamin D, ferritin, and comprehensive metabolic panels.
