I’m two weeks into my Healthnix journey and already feeling the difference, less fatigue, less bloating, and no more midday naps! After years of trying restrictive diets that hurt my mental health, this approach feels supportive and sustainable. My RD helps me find realistic swaps (even at restaurants!) instead of cutting things out. Finally, a way of eating that actually works for me.
I know it’s only been one week (barely) but in just this little time, I’m feeling so much better. Can you imagine how much better I will feel in a month.. two months.. six months? Amazing. My head (brain) is thinking so clearly. It’s crazy. It seems if I encounter an obstacle or issue, I […]
I know it’s only been one week (barely) but in just this little time, I’m feeling so much better. Can you imagine how much better I will feel in a month.. two months.. six months? Amazing. My head (brain) is thinking so clearly. It’s crazy. It seems if I encounter an obstacle or issue, I have the energy and know-how to solve or remedy it — almost immediately. Is this your experience as well?

I first had a conversation with Hillary about 9 weeks ago. I had just found out I had osteoarthritis and was in constant pain and feeling quite despondent. Hillary spoke to me about what I hoped to achieve, I said I would like to be healthier, to not be in constant pain and to hopefully slow down the symptoms of arthritis. We spoke about what food I was eating, likes/dislikes. Hillary then went through how I could make positive changes to my diet. I have taken on board everything she said, I love my breakfast of yoghurt fruit and muesli every morning. I have cut out almost all ultra processed foods. I have lost 2kg already really easily, as I don’t really get hungry anymore. My pain has reduced enormously due to the changes in my diet. I can’t thank Hillary enough for giving me the confidence I needed to make these changes.
Hillary has provided thoughtful, tailored guidance to help reach my goal of losing weight and improve my health whilst living with arthritis, without completely cutting out the foods I enjoy. Hillary has a good knowledge of food and nutrition, and was able to suggest lots of new foods and dishes I could eat to help […]
Hillary has provided thoughtful, tailored guidance to help reach my goal of losing weight and improve my health whilst living with arthritis, without completely cutting out the foods I enjoy. Hillary has a good knowledge of food and nutrition, and was able to suggest lots of new foods and dishes I could eat to help me lose weight by improving my diet. She also provided information about foods to avoid or cut back on because they can trigger inflammation or are generally unhealthy. I’m grateful for her expertise and support.
I was lucky enough to have two 1 hr consultations with Hillary regarding dietary issues. I benefitted from some very good nutritional advice to aid with weight loss and cholesterol control, and have subsequently introduced some new items into my diet to further enhance these aims.

I was lucky enough to have two 1 hr consultations with Hillary regarding dietary issues. I benefitted from some very good nutritional advice to aid with weight loss and cholesterol control, and have subsequently introduced some new items into my diet to further enhance these aims. Although my diet was acknowledged as being good overall, Hillary helped me with some fine tuning that I’m sure will benefit me in the long term. I feel I learnt some valuable things from Hillary and found her to be very professional, thorough and a pleasure to talk with. I do feel my energy levels, which were very poor due to constant pain or at best severe discomfort, have started to improve.
I’ve now had my first call with Nicole in which she spent over an hour talking me through everything and giving advice. Nicole then followed up our call with a lengthy, really informative email which has made me feel very positive about my new eating plan and the start of becoming much healthier and hopefully […]
I’ve now had my first call with Nicole in which she spent over an hour talking me through everything and giving advice. Nicole then followed up our call with a lengthy, really informative email which has made me feel very positive about my new eating plan and the start of becoming much healthier and hopefully reducing my daily pain etc. I will be having a call with her again towards the end of July but she has told me I can contact her any time if I need any extra help which is really good to know. I just wanted to share my positive experience with her this morning.

12-week Personalized Nutrition Program
A 12-week experience combining lab testing, personalized nutrition, and daily expert support. You’ll get:
Healthnix is built for people who want to explore using nutrition and lifestyle changes to navigate chronic pain, autoimmune symptoms, or inflammation-related conditions like IBS, PCOS, diabetes, and fatigue. While symptoms vary — joint pain, gut issues, brain fog, exhaustion — many trace back to underlying inflammation, gut imbalances, or immune dysfunction. That’s where your assigned registered dietitian will focus. Our program is specifically designed to facilitate how you and your dietitian work together to connect the dots between your labs, symptoms, and lifestyle choices — so you can finally start getting answers that make sense for your body and feel better.
No. Healthnix is 100% insurance-free. No deductibles. No co-pays. No surprise bills. One transparent price, everything included. (Note: We are not currently FSA/HSA eligible.)
Available throughout the continental U.S. Lab testing is conducted via Quest Diagnostics (47 states) and Bioreference Labs (NY, NJ) — with access to 2,000+ locations nationwide.
Note: We are not able to facilitate lab testing in Rhode Island. Residents of RI will need an address in another state to participate.
The Healthnix program includes 73 biomarkers across the following groups:
These categories provide a comprehensive view of your health and nutrition needs. For a detailed list of every biomarker (with Quest LOINC codes) and their dietary implications, view the complete lab panel here.
Note: In New York and New Jersey, testing is performed through Bioreference Laboratories. Their reports may show more LOINC codes due to how results are mapped, but the biomarkers tested are equivalent.
The Healthnix program is designed to be light-touch and easy to fit into daily life. Here’s what to expect:
