Functional Medicine in
Midtown Manhattan

You’ve been told your labs are normal. You’ve been handed prescriptions that manage symptoms but never resolve them. You’ve been told that what you’re feeling is just stress, just aging, just hormones — and you’re not buying it, because you know your body. MSM Wellness is built for people ready to find the actual reason they don’t feel well, and to do something about it.

What is Functional Medicine?

Functional medicine is a root-cause approach to healthcare that asks one simple question:

“Why is this symptom happening in the first place?”

Too often, healthcare focuses on managing symptoms rather than understanding why they developed. While medications certainly have an important time and place, they don’t always answer the question of what is driving the problem. Functional medicine takes a deeper, more individualized approach—looking beyond the symptoms to identify the underlying factors contributing to them. By understanding why symptoms developed, a personalized plan can be created to help restore function, optimize health, and improve long-term well-being.

This looks like a Comprehensive review of symptoms, history and lifestyle. Individualized thorough testing that goes beyond a traditional work up, so nothing is missed. We then connect the dots to create a personalized plan tailored specifically to you—not a cookie-cutter protocol based solely on a diagnosis or symptom.

Meet Dr. Robert Foster, DC, CFMP

Dr. Robert Foster, known to many patients as Dr. Bob, is a Certified Functional Medicine Practitioner (CFMP) and Board-Certified Chiropractic Physician licensed in both New Jersey and New York. He earned his Doctor of Chiropractic degree from New York Chiropractic College and holds a Bachelor’s degree in Exercise Science from Binghamton University.

Through both professional training and personal health experiences, Dr. Bob developed a passion for uncovering the root causes of chronic symptoms and complex health conditions. After navigating his own personal battle with Lyme disease and autoimmune-related conditions, he became increasingly drawn toward Functional and Integrative Medicine when conventional approaches failed to provide lasting answers.

Today, through FNXN Health & Longevity, Dr. Bob focuses on a comprehensive, systems-based approach to health that looks beyond symptom management and aims to restore function within the body’s core systems.

His work emphasizes detailed health histories, advanced bloodwork interpretation, and specialty functional medicine testing to better understand the underlying drivers of chronic or unexplained symptoms. He then integrates practical lifestyle strategies, nutrition, targeted supplementation, and patient education to help patients better understand their bodies and actively participate in their healing process.

In addition to functional medicine, Dr. Bob has extensive training in lymphatic drainage therapies, vagus nerve stimulation techniques, soft tissue therapies, and nervous system-focused manual work. He incorporates both hands-on techniques and guided at-home exercises to help patients better manage stress, anxiety, and chronic pain patterns.

Above all, Dr. Bob believes that healing requires a personalized and comprehensive approach — one that recognizes that symptoms are often signals of deeper dysfunction rather than isolated problems to suppress.

When not working with patients, Dr. Bob enjoys spending time with his wife, daughter, and their dog, Cooper. He is an avid skier, cyclist, and lifelong advocate for movement, wellness, and longevity. A fun fact about Dr. Bob: he still starts most mornings with a cold plunge.

Cortisol and Impact on Sleep, Fatigue, Stress

Symptoms & Conditions Commonly Evaluated

Fatigue & Low Energy

Feeling exhausted despite getting enough sleep? Relying on caffeine to make it through the day? Hitting an afternoon crash? Low energy isn’t normal. By looking beyond symptoms and identifying the root cause whether it’s your thyroid, hormones, nutrition, gut, or another imbalance—we can create a plan to help restore your energy.

Gut Health

Bloating, constipation, diarrhea, reflux, food sensitivities, and IBS aren’t just symptoms to manage—they’re signs that something deeper may be going on. By identifying what’s driving your digestive issues, we can create a personalized plan to restore gut health. And because the gut influences inflammation, skin, mood, and immune function, improving it often benefits far more than just digestion.

Anxiety, Mood & Cortisol

New or worsening anxiety, feeling overwhelmed, irritability, poor sleep, or mood changes aren’t always “just stress.” Hormones, cortisol, blood sugar, thyroid function, gut health, and inflammation can all influence how you feel. By looking at these systems together, we can better understand what’s contributing to your symptoms and where to focus first.

Hair Loss & Thinning

Hair loss and thinning can be frustrating, but they’re often signs of an underlying imbalance rather than simply aging. Thyroid dysfunction, low iron, hormonal changes, stress, nutrient deficiencies, and inflammation can all play a role. We look beyond the hair itself to identify the underlying factors and support healthy hair growth from the inside out.

Skin Health

Adult acne, eczema, psoriasis, and other skin conditions are often signs of deeper imbalances in the body. While the gut-skin connection is well established, hormones, stress, nutrition, and inflammation can all contribute. Prescription medications and topical treatments can be very effective at controlling symptoms, but they don’t always address the underlying contributors. That’s why we look beyond the skin itself to better understand what’s driving your symptoms.

Thyroid & Hashimoto's

If you’ve been told your thyroid is “normal” but you’re still struggling with fatigue, weight gain, temperature regulation, brain fog, or hair loss –  there may be more to the story. Standard thyroid testing doesn’t evaluate the full picture. By looking beyond TSH alone and evaluating your actual thyroid hormone levels—such as Free T3, Free T4, and other important markers—we can better understand whether your thyroid is truly functioning optimally and identify other factors that may be contributing to your symptoms.

Perimenopause & Menopause

Hot flashes, night sweats, poor sleep, brain fog, mood changes, weight gain, and worsening PMS are common during perimenopause and menopause—but they don’t have to be accepted as “just part of aging.” While declining estrogen and progesterone play an important role, changes in thyroid function, blood sugar regulation, cortisol, and other body systems often contribute as well. We look beyond hormone levels alone to understand how your body’s systems work together and identify what’s really driving your symptoms.

Men's Health

Fatigue, low libido, brain fog, weight gain, and declining performance often occur together—but testosterone isn’t always the whole story. Sleep, stress, thyroid function, nutrition, and gut health can all influence how you feel. Our goal is to identify and address the factors that may be lowering testosterone while optimizing hormone levels as part of a comprehensive approach to improving your health.

How Dr. Foster is Different

Conventional healthcare is often designed around short, problem-focused visits—addressing one symptom at a time, ordering basic labs, and frequently turning to medication or referral as the next step. While this approach has an important role in healthcare, many patients are left wondering why they still don’t feel well despite being told their results are “normal.”

Dr. Foster takes a different approach. Appointments allow time to understand your complete health history, symptoms, lifestyle, and how seemingly unrelated problems may actually be connected. When appropriate, comprehensive testing goes beyond the standard workup to evaluate areas such as thyroid function, hormones, cortisol, gut health, metabolism, and nutrient status. The goal is to connect the dots, uncover what’s driving your symptoms, and build a personalized plan you can actually follow.
