Welcome
Hi, I'm Jaclyn, a Board-Certified Clinical Nutritionist based in Babylon, NY. I take a personalized, comprehensive approach to nutrition, helping clients connect the dots and better understand what may be contributing to digestive issues, fatigue, weight changes, anxiety, inflammation, and other symptoms that can be difficult to make sense of.
My approach combines whole-food nutrition, sustainable habit change, a comprehensive health history, and evidence-based assessment of bloodwork and specialized testing when appropriate so we can look beyond individual symptoms and understand the bigger picture.
I created my Essential Core4 Framework to assess four interconnected areas- inflammation & stress, metabolism & nutrient status, gut & immune health, and hormones & mood and turn what we learn into a realistic, personalized plan you can actually follow.
Nutrition Specialties
As a clinical nutritionist serving Babylon and Long Island, I help clients connect the dots across several interconnected areas of health:
Inflammation → Chronic inflammation, joint discomfort, skin concerns, cardiometabolic health, and liver health.
Metabolic Health → Blood sugar balance, prediabetes and diabetes, energy crashes, cravings, fatigue, high cholesterol, blood pressure, fatty liver, and sustainable weight management.
Hormonal Health → Women's health, perimenopause, thyroid health, sleep, and stress resilience.
Gut Health → Bloating, constipation, digestive discomfort, food sensitivities, intestinal permeability, and SIBO.
Mental & Emotional Well-Being → Anxiety, mood, chronic stress, brain fog, burnout, and nutrition-related factors that may influence mental well-being.
What Clients Are Saying
The Essential Core4 Framework
Everything is connected.
The Essential Core4 Framework is how I organize my comprehensive approach to nutrition, looking across four interconnected areas that can influence how you feel.
Rather than focusing on a symptom in isolation, I consider your nutrition, symptoms, health history, bloodwork, medications and supplements, sleep, stress, movement, and specialized testing when appropriate to help connect the dots and identify potential contributors.
From there, we create a personalized, evidence-based plan based on what your body actually needs.
1. Inflammation & Stress
Looking at factors that may contribute to inflammatory burden and your body’s ability to adapt to stress.
2. Metabolism & Nutrient Status
Looking at blood sugar regulation, energy, nutrient sufficiency, metabolic health, and how your body is being fueled.
3. Gut & Immune Function
Looking at digestion, gastrointestinal symptoms, gut function, the microbiome, and factors that may influence immune health.
4. Hormones & Mood
Looking at nutrition and lifestyle factors that intersect with hormonal health, mood, sleep, and stress regulation.
These areas don’t exist in isolation. The Essential Core4 Framework helps me look at the bigger picture, understand how different aspects of your health may be connected, and determine where nutrition and lifestyle changes may have the greatest impact.
Does This Sound
Like You?
You don’t need another restrictive diet or overwhelming list of rules. You need to understand why you don’t feel your best and have a realistic plan for what to do about it.
You may be in the right place if any of these sound familiar:
“I'm tired of feeling bloated and uncomfortable all the time.”
“My energy, mood, and cravings are all over the place.”
“I've done the labs, but I still don't have a clear plan.”
“I want to eat better without tracking every bite or cutting everything out.”
