What is a Functional Nutritionist?
A functional nutritionist plays a crucial role in promoting optimal health and well-being through a holistic approach to nutrition. Unlike traditional nutritionists, a functional nutritionist goes beyond basic dietary recommendations and explores the interconnections between various bodily systems, lifestyle factors, and individualized needs. By understanding the intricate relationship between diet, genetics, environment, and overall health, functional nutritionists are able to develop personalized plans that address the root causes of health issues rather than merely treating symptoms. They emphasize the importance of whole, nutrient-dense foods, while also considering factors like gut health, inflammation, hormonal balance, and food sensitivities. By taking into account the unique biochemistry of each individual, a functional nutritionist can guide them towards optimal health, which can lead to improved energy, enhanced immunity, better digestion, and overall vitality. In a world where chronic diseases are on the rise, the role of a functional nutritionist becomes increasingly important, offering a preventive and proactive approach to health that empowers people to take charge of their well-being and make lasting, positive changes.
About me
My name is Nadine Campbell, and I am a board-certified functional nutritionist in New York City and the Hamptons, specializing in gut health, chronic inflammation, and longevity. I hold a Master of Science in Human Nutrition from the University of Bridgeport, where my studies focused on functional medicine, biochemistry, and pathophysiology. As a functional nutritionist, I take a root-cause approach to health. Rather than simply managing symptoms, I work with you to uncover the deeper imbalances that may be driving your health concerns. Each client is unique, so I consider diet, lifestyle, medical history, family history, and emotional well-being to create a comprehensive plan tailored to your needs. When helpful, I also utilize both functional and conventional lab testing to gain deeper insights.
My areas of expertise include:
Gastrointestinal health & gut microbiome balance
Chronic inflammation & immune support
Metabolic syndrome & blood sugar balance
Food sensitivities and intolerances
Because the gut is central to so many systems in the body, much of my work focuses on gut health and digestion. Research continues to show how the gastrointestinal tract, immune system, and microbiome are interconnected and influenced by diet. By restoring digestive balance, we often see improvements across energy, immunity, inflammation, and overall vitality.
I divide my time between New York City and the Hamptons, where I work with clients in person, as well as virtually for those who prefer online sessions. Whether you are seeking relief from digestive issues, struggling with inflammation, or simply want to optimize your long-term wellness, my goal is to help you feel empowered, resilient, and truly well.
