Meet Andrea Zajac:
The Gut-Glowing, Hormone-Hacking, Brain-Fueling RD Boss Lady
She’s not just a Registered Dietitian — she’s a recovery renegade,
a functional nutrition force, and a precision-powered pro
who could probably teach half the field a thing or two (or twenty).
Whether she's calming cortisol, boosting butyrate, or decoding
DUTCH tests like a biochemical detective,
Andrea blends deep science with soul-centered care.
With a heart for Gut-Brain-Hormonal axis and a head for metabolomics,
she tailors every macro, micronutrient, and supplement like it’s couture.
She's building better guts, clearer minds, and stronger bodies—
one customized plan, one powerful conversation at a time.
When she’s not balancing testosterone metabolism for her MDD patients or
turning a men’s Trauma Therapy group onto mindful eating,
she’s sprinting through SIT workouts, brewing kefir magic, or
dreaming up anti-aging skin concoctions with L. reuteri and L. Plantarum.
Are you missing out on living a full life?
Are you experiencing GI distress that keeps you close to the bathroom?
Are you experiencing insulin resistance?
Do you have elevated cholesterol, triglycerides or blood sugar levels?
Are you beyond frustrated that you are eating less & still gaining weight in crazy places?
Are you on or considering a GLP1 for
DM support or weight loss?
Then you could benefit from my personalized,
precision Medical Nutrition Therapy!
Together we create a lifestyle change - not a diet.
You need something that you can stick with that is
manageable, safe and sustainable.
I help you find MORE foods to eat within your health parameters.
Yep, you read that correctly!
I want you to eat MORE incredibly colorful, fresh &
delicious foods to help you reach your health goals.
Did you know that more women over 50 develop
disordered eating than being diagnosed with breast cancer?
Together, we'll create an evidence-based nutrition plan that
supports a positive, healthy relationship with food
without restricting the things you love!
Optimal health starts with understanding your unique biology.
I recommend targeted functional lab tests for clients who want to uncover the root
causes of their symptoms and optimize their nutrition plan for lasting results.
These advanced assessments provide deep insights into hormone balance (DUTCH test),
genetic influences on metabolism (Nutrigenomics),
micronutrient status and detoxification pathways (NutrEval), and
gut health (GI Mapping). By leveraging this data, we can create a highly
personalized medical nutrition strategy that enhances nutrient
absorption, supports metabolic function, and maximizes energy and well-being.

What is Medical Nutrition Therapy?
Medical Nutrition Therapy (MNT) is an evidence-based, individualized nutrition process meant to help treat certain medical conditions.
It is covered by Medicare for Diabetes, Chronic Kidney Disease, and transplant.
MNT is developed and implemented by an RDN with the approval of the patient’s doctor.
MNT may be conducted in a hospital, in an outpatient clinic, or as part of a telehealth program.
What To Expect:
When MNT is not needed, patients can benefit from
personalized nutrition counseling & education.
During your initial assessment, our Registered Dietitian/Nutritionist (RDN) will collect biomedical, clinical and environmental information to create a treatment plan with an accurate nutrition diagnosis. Labs, medications, history of illness, family genetics, nutrigenomics, and lifestyle will be evaluated. Patients will receive a Nutrition Focused Physical Exam if deemed necessary for malnutrition evaluation.
Our RDN will provide a nutritional diagnosis and a treatment plan.
In addition to your treatment plan, proper monitoring and evaluating of health goals will occur. Patient-led goals allow partnership with accountability.
We can also customize a 7-Day Meal Plan, provide Meal Services and provide weekly, on-call, Concierge Dietitian/Nutrition Services.

Is a Registered Dietitian/Nutritionist the same as a Nutritionist?
Anyone can call themselves a nutritionist and there is no legislation for being a nutritionist.
However, only a Registered Dietitian/Nutritionist (RDN) can call themselves a Dietitian and only an RDN can provide medical nutrition therpy & counseling and diagnose & treat a nutritional diagnosis.
Inpatient Registered Dietitians provide expert guidance in hospital settings to include intensive care units where TPN and Tube Feedings may be required. They also work in medical/surgical wards for post-operative care. Outpatient Dietitians work with patients as they discharge from the hospital with the need for nutritional management for their medical diagnosis. Cognitive Behavioral Therapy, Motivational Interviewing and Behavioral Modification are techniques used when providing nutritional counseling by a Dietitian. Community Dietitians work to educate the public by creating nutrition-focused programs aimed at disease prevention, improving health outcomes and overall quality of life. Registered Dietitians also run hospital food service departments at hospitals, universities and large instititutions.
What qualifications do RDNs have?
Dietitians must complete a Bachelors in Science with at least a 1200 hour accredited didactic internship covering all modalities before passing an intensive 3-hr board exam.
