Susan Markowitz RDN
Registered Dietitian Specializing in Integrative & Functional Nutrition

For over 30 years, I’ve worked at the forefront of functional nutrition, mastering the science of human physiology in the high-stakes world of critical care. I saw firsthand the power of nutrition to save lives - but I also saw a broken system. We were waiting for people to break down rather than building them up.

I refused to accept that the "norm" is a slow decline. I founded Nutrition Happiness to shatter that paradigm. I bridge the gap between rigorous hospital-grade science and the holistic power of functional medicine.

My mission is simple: to help you take back control of your biology. whether you are in New Jersey or joining me from across the nation, we won't just manage your symptoms - we will optimize your energy, ignite your longevity, and create the extraordinary health you deserve.
