The Wellness Clinic
Lab testing, nutrition, and functional care that gets to the root of how you feel, not just the surface
What Is The Wellness Clinic?
We start with the basics most people have never actually had time to fix. How you sleep. How you move. What you're putting in your body and how it's using it. The Wellness Clinic is built on the belief that these foundations come first, and everything else, testing, nutrition support, hormone work, builds on top of that groundwork instead of skipping past it.
-
Before we add anything new, we look at what's already there. This is a full look at your sleep, movement, and daily nourishment, the foundations that have to be steady before testing or protocols can really work. It's often the step that gets skipped, and usually the one that matters most.
-
Standard bloodwork often misses what's actually going on. We use functional and metabolic testing, hormone panels, and tools like DUTCH testing to get a real picture of what's happening in your body at the biochemical level. This is where guesswork stops and your plan starts being built on your actual numbers, not averages.
-
Food is information for your body, and most of us were never taught how to read it. This is hands on support for building a way of eating that actually matches your metabolism, your goals, and your day to day life, not a generic meal plan pulled off a chart. We look at blood sugar regulation, nutrient density, and what's realistic for you to sustain
-
Your body runs on rhythm, when you sleep, when you eat, when you're exposed to light, and when you move all send signals that shape your mood, energy, and resilience. When those rhythms get disrupted, whether from irregular sleep, screen exposure at night, or inconsistent routines, it can directly affect mental health, inflammation, and metabolic function. In this area of care, we look at your daily patterns and biological timing to help restore the rhythms your body needs to function and feel well, using practical, sustainable changes rather than more medication.
-
Not every body needs the same support, and more isn't always better. This is where we get specific, choosing peptides and supplements based on what your labs and symptoms are actually telling us, so you're not wasting money or guessing your way through a supplement aisle.
Functional & Metabolic Lab Testing
Why Lab Testing Matters
Guessing isn't a plan, and neither is treating a symptom without understanding what's actually causing it. Hunger, energy, mood, sleep, and weight are all managed by hormones and metabolic processes happening underneath the surface, and the only way to really see what's going on is to look. That's what lab testing gives us, a clear, individual picture instead of a guess based on averages.
Standard checkups often stop at "your labs are normal," even when you don't feel normal at all. Functional and metabolic testing goes further, looking at hormone balance, thyroid function, blood sugar regulation, inflammation, and nutrient status so we can catch what a basic panel misses. Once we know what's actually happening in your body, we can build a plan around your biology instead of a one size fits all approach that was never built for you in the first place.
Nutrition & Metabolic Coaching
Why Nutrition & Metabolic Coaching Matters
Most nutrition advice out there is built for someone who doesn't exist, a generic person with generic goals and a generic metabolism. But your body processes food differently than your neighbor's, your sister's, or whoever's meal plan you found online. What actually works is understanding how your specific body handles blood sugar, where your energy dips during the day, and what kind of eating pattern you can realistically stick with long term, not just for two weeks.
This isn't about restriction or another diet to fail at. It's about learning to read your own body's signals so food starts working for you instead of against you, and building something sustainable enough that it just becomes how you eat, not something you're white knuckling through.
Peptide & Supplement Strategy
Why Peptide & Supplement Strategy Matters
Walk into any supplement aisle and you'll find a hundred products all claiming to fix the same problem, and most people end up guessing, or worse, taking everything at once and hoping something sticks. That's expensive and it's not actually strategic.
The better approach starts with your labs and your actual symptoms, not a trend you saw online. Once we know what your body is genuinely low on, or what pathway needs support, we can choose specific peptides or supplements that are doing real work, instead of throwing things at the wall. More isn't better here, targeted is better.
Circadian Biology & Lifestyle Medicine
Why This Matters
Your body runs on rhythm, when you sleep, when you eat, when you're exposed to light, and when you move all send signals that shape your mood, energy, and resilience. When those rhythms get disrupted, it can directly affect mental health, inflammation, and metabolic function. We look at your daily patterns and biological timing to help restore the rhythms your body needs to feel and function well, using practical, sustainable changes rather than more medication
Why a Foundational Health Assessment Matters:
It's tempting to want to skip straight to testing and protocols, but if your sleep is wrecked, you're not moving your body, and your nourishment is an afterthought, no amount of advanced testing is going to hold up on top of that. Foundations first isn't a slower path, it's the one that actually works.
This assessment looks at the basics most people have never gotten real support around: how you sleep, how you move, and how you're nourishing yourself day to day. Getting these steady is often the step that changes the most, and it's usually the one that gets overlooked entirely in favor of something that feels more advanced
Direct-to-Consumer Labs:
Most people only think of lab testing as something that happens after a doctor's visit, ordered through insurance, on someone else's timeline. Direct-to-consumer (DTC) labs work differently. These are labs you can order yourself, without needing an appointment first, so you can get a clear picture of what's happening in your body on your own schedule.
This is about giving you more access to your own information, not replacing the value of working with a provider. Once you have your results, that's exactly where working with Jennifer and Jay matters most, they can help you actually understand what they mean and what to do next.
More Ways to Access Your Own Health Information
Jennifer can order labs directly as part of your ongoing care, and she accepts insurance as a primary provider. Jay works alongside her on the nutrition and metabolic side, translating those labs into a plan you can actually live with. This route works well if you want an established relationship with a team managing your care over time.
As your provider:
You can also order select labs on your own, outside of insurance, without needing a visit first. This is a good fit if you already know what you're looking for, or you want to explore before committing to ongoing care.
Either way, you're the one deciding how involved you want a provider to be. That's the point. Healthcare doesn't have to be one path for everyone.
Direct-to-consumer:
A quick note: due to state regulations, direct-to-consumer lab ordering isn't available to residents of New York, New Jersey, or Rhode Island. This applies to the self-service labs specifically, if you're an established patient working with Jennifer and Jay directly, labs can still be ordered as part of your care regardless of where you live.

J Gulinello, MS, CNSc, FNTP
Clinical Nutritionist| Functional Nutrition Specialist | Metabolic & Ancestral Health Educator
J is a clinical nutritionist with a master’s degree in Clinical Human Nutrition (MS), graduating with honors, and advanced certification as a Certified Nutrition Specialist Candidate (CNSc). With years of experience in functional nutrition, metabolic coaching, and lifestyle intervention, he brings a deeply evidence‑based yet ancestrally informed approach to human health.
His path into nutrition began unconventionally. After earning a degree in Music Production & Engineering from Berklee, J’s lifelong love of athletics led him to become an ISSA‑Certified Personal Trainer with a specialty in Fitness Nutrition. What started as a curiosity quickly became a professional calling: he immersed himself in the science of longevity, metabolism, and human performance — reading extensively, attending conferences, and collaborating with MDs, PhDs, and engineers.
Realizing that much of conventional nutrition was built on outdated or incomplete science, J pursued formal training through the Nutritional Therapy Association, becoming a Functional Nutritional Therapy Practitioner (FNTP). This training emphasized a bio‑individual, systems‑based approach focused on digestion, fatty acids, minerals, hydration, and blood sugar regulation — the foundations of metabolic resilience.
J later completed his master’s degree in Clinical Human Nutrition, where he worked with physicians and nurses in a New York City hospital system to improve employee health outcomes through nutrition, sleep optimization, stress physiology, and lifestyle medicine. His graduate work strengthened his expertise in clinical assessment, therapeutic nutrition, and metabolic intervention.
Today, J specializes in:
Low‑carbohydrate and ketogenic nutrition
Fasting protocols and metabolic flexibility
Ancestral and evolutionary nutrition
Performance nutrition and longevity science
Functional nutrition for whole‑body systems
Metabolic health for Mental Health
He continues to conduct independent research through an ancestral and evolutionary lens, and he leads in‑person retreats designed to reconnect people with the foundations of human health.
Outside of his clinical work, J is an avid mountain climber, endurance athlete, and lifelong student of human performance. His blend of academic rigor, functional nutrition training, and real‑world coaching experience allows him to help individuals optimize their physiology, reclaim metabolic health, and live with greater vitality.
