Anti-inflammatory Bundle 


Food-first functional nutrition therapy services prioritize using dietary interventions to optimize health, focusing on personalized approaches tailored to individual needs. The core of LWell Functional Nutrition programs lies in the innovative methodologies of MRT (Mediator Release Test) and GI mapping. MRT tests identify specific food sensitivities and intolerances, guiding the creation of customized dietary plans to reduce inflammation and improve overall well-being. Concurrently, GI mapping offers insights into gut microbiome composition and function, informing targeted strategies to promote digestive health. LWell Functional Nutrition services emphasize a comprehensive approach, complementing dietary modifications with lifestyle adjustments to achieve sustainable results. Unlike traditional medical nutrition therapy, LWell Functional Nutrition is a deeper dive into personalized wellness, offering a holistic perspective that addresses underlying factors contributing to health imbalances. Patients receive structured guidance and support to embark on a transformative journey toward optimal health and vitality.

How does it work?  

Upon enrollment in a program, you’ll be prompted to complete an extensive health questionnaire in addition to enrollment forms, followed by the delivery of two kits to your doorstep. GI mapping requires a comprehensive stool analysis, the results of which will be forwarded to your practitioner for evaluation. Other tests like MRT, IgG, and micronutrient testing necessitate a blood draw, conveniently facilitated at the LWell office. Upon receipt of both test results, our functional medicine practitioners meticulously analyze the data to formulate a tailored program. During your consultation, you’ll collaborate with the practitioner to review and adjust the program according to your preferences and lifestyle. At this juncture, you can choose whether to engage with a health coach, a registered dietitian, or continue receiving guidance from a functional practitioner based on your ongoing needs.
