Dr. Brandon Mannie

Dr. Brandon Mannie is a board-certified functional medicine practitioner with over 400 hours of post-graduate training in clinical nutrition and functional medicine. He graduated from the prestigious Northwestern Health Sciences University in 2004 and has been in private practice ever since.

Over the past 20+ years, Dr. Mannie has consulted with more than 3,000 patients — people who were told their labs were "normal," yet still felt far from well. His approach goes beyond symptom management: he investigates the root causes driving chronic illness and builds personalized protocols that restore true, lasting health.

His clinical passions include weight loss resistance, thyroid dysfunction, type 2 diabetes, and autoimmune disease. He now operates a fully virtual practice, helping patients from all across the country from his home in College Grove, TN, where he lives with his wife Megan and their four children — Jonah, Micaiah, Isaac, and Hannah.

Most patients who come to Dr. Mannie have already seen multiple doctors. They've been told their labs are "normal," been handed prescriptions that mask symptoms, and sent home without real answers. That's the gap functional medicine is designed to fill.

Dr. Mannie's approach starts with listening — understanding your full health history, lifestyle, genetics, and environment — then running advanced functional lab panels that conventional medicine rarely orders. The result is a truly personalized protocol, not a one-size-fits-all prescription.

"I've seen patients who were dismissed for years finally get real answers and real results. That's why I do this work."

— Dr. Brandon Mannie

"Functional medicine isn't alternative medicine. It's the medicine of asking 'why' — and not stopping until you find the answer."

— Dr. Brandon Mannie
