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 why a symptom is happening rather than simply suppressing it. Instead of treating fatigue with caffeine, hormonal acne with antibiotics, or perimenopausal symptoms with birth control, functional medicine identifies the underlying drivers hormonal imbalances, gut dysfunction, nutrient deficiencies, chronic inflammation, cortisol dysregulation, thyroid issues, or environmental exposures and builds a personalized plan to correct them. The result is symptom resolution that lasts, not management that requires a prescription forever.

At MSM Wellness, that means comprehensive lab testing that goes well beyond what conventional medicine runs, careful attention to the connections between body systems (your gut affects your hormones, which affect your skin, which affect your mood), and treatment plans designed for you specifically not a protocol you share with everyone else who walked through the door.

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.

What Dr. Bob Treats

Fatigue & Low Energy

Persistent fatigue is the most common reason patients come to MSM Wellness. If you’re exhausted despite sleeping, dependent on caffeine, or crashing every afternoon, there is a reason. Comprehensive testing identifies whether the driver is thyroid, cortisol, hormones, nutrients, or gut, and treatment targets the actual cause.

Gut Health

Bloating, IBS, constipation, food sensitivities, and reflux are signals from a gut system out of balance. Underneath an “IBS” label, we typically find SIBO, parasitic or yeast overgrowth, histamine intolerance, or hormonal influences on motility. Because the gut produces most of your serotonin and metabolizes your hormones, fixing it changes far more than digestion.

Perimenopause & Menopause

If you’re 35–55 and noticing hot flashes, night sweats, sleep disruption, anxiety, brain fog, or PMS that has worsened — you’re in perimenopause, even if your periods are still regular. We treat with a combination of bioidentical hormones when appropriate, cortisol support, gut work, and nutrient repletion.

Hair Loss & Thinning

Hair loss in women almost always has an identifiable cause — thyroid dysfunction, low ferritin (which needs to be above 70 for regrowth, not just “normal”), perimenopausal shifts, or cortisol elevation. Many of our patients are on Nutrafol; we help determine whether it’s actually the right fit and coordinate it with root-cause work.

Skin: Hormonal Acne, Eczema

Adult acne, eczema, and psoriasis are inflammation problems that surface on the skin. The gut-skin connection is well-documented, which is why these conditions respond to systemic root-cause work in ways that topicals can’t match.

Thyroid & Hashimoto's

If your TSH came back “normal” but you’re tired, cold, losing hair, and struggling with weight — the wrong test was run. A complete thyroid panel includes TSH, free T4, free T3, reverse T3, and both antibodies. Catching Hashimoto’s early lets us slow the autoimmune process before significant damage.

Anxiety, Mood & Cortisol

New-onset or worsening anxiety in your 30s, 40s, or 50s is rarely just “stress.” It’s usually a measurable cortisol pattern, a perimenopausal hormonal shift, or a gut-driven inflammatory state. Most patients see meaningful mood improvement within 8–12 weeks.

Men's Health

Men typically present with fatigue, low libido, low testosterone, gut issues, and anxiety — often together. Low testosterone is increasingly common under 40 and rarely standalone. We address the root drivers before defaulting to testosterone replacement.

How Dr. Foster is Different

A conventional appointment runs 7–15 minutes and ends with a prescription or a referral. MSM Wellness appointments run 60–90 minutes for new patients and 30–45 minutes for follow-ups, with time built in to actually understand your history and what’s connected to what.

We use comprehensive labs that look at the systems conventional medicine skips — full thyroid panels, complete hormonal evaluations, four-point cortisol testing, stool testing for the microbiome, and nutrient panels. And we build plans you can actually follow, with the support to follow them.
