What Clients If you're looking for nutrition and diet consultation in Miami come to Jessica at NextGeneration Nutrition. I am a sports/ortho physical therapist in the area and had a great experience. I eat healthy and exercise regularly but knew I needed some gut health assistance.  I received blood work and supplements from Jessica to improve my G.I. function. I felt the difference with her recommendations within 2 weeks. Also, her online consultation was easy to fix in my schedule!

Jessica from Next Generation Nutrition is outstanding! When I started my nutrition wellness journey, I didn’t have any idea of what to expect and I was a bit skeptical about the process. However, after working with Jessica for almost 5 months, I can confidently say that becoming her client was the right decision to make.  She is very knowledgeable and kind.  She has not only educated me on topics related to nutrition, macros, gut health, oils, and mindful eating but she has completely helped change my relationship with food (think therapy for the gut ).  Working with her, we were able to identify some vitamin deficiencies in my body and I have been taking supplements that have helped improve that. We have also worked on meal plans and food choices that have made healthy eating something not only attainable but sustainable. I find myself making better choices when it comes to food without sacrificing proper nutrition or enjoyment.  She has also been very encouraging of my exercise routine (I have been using a Peloton bike and app).  I humorously call my wellness plan the “holy trinity:” nutrition, supplements, and exercise. This has NOT been a diet for me but a journey to leading a healthier lifestyle… and today, 20 pounds lighter and eating more than I used to, I can sincerely say: Thank you, Jessica. You changed my life for the best! And to you reading this testimonial I say: remember that a “journey of a thousand miles starts with a single step” and maybe this is that single step for you.  Believe me, it is worth it; you are worth it!
