Functional Medicine Practitioner & Gut Health Nutrition Specialist

My holistic journey began 16 years ago when dietary changes helped my speech-delayed son, then considered on the spectrum, make remarkable progress. That life-changing experience sparked my deep belief in the body’s ability to heal and set me on a path to support others in their wellness journeys.

I’m a ReCODE 2.0 Certified Nutritionist, Board Certified Applied Functional Medicine Practitioner, Integrative Nutrition Health Coach, and Gut Health Nutrition Specialist. I work independently with clients and collaborate closely with their primary care or ReCODE 2.0 Certified physicians to support them on the Bredesen Protocol®. My work centers on personalized care that integrates functional testing, red light therapy, sauna therapy, and BrainTap to address root causes and optimize cognitive and overall health.

At the core of my work is personalized nutrition—helping clients with glucose and ketone monitoring, meal planning, and sustainable habits. My approach is root-cause-focused, collaborative, and supportive, empowering each client to take charge of their health and build lasting wellness

“Karin Mullooly changed my life! I had been treated unsuccessfully for the prior 9 months by one of the area’s top GI practices and was in constant pain, frustrated, and depressed. Karin reviewed the exact same information from all the tests, scans, and bloodwork my docs had ordered but arrived at a completely different and, we now know, accurate diagnosis. I am pain free and actually feel better than ever. Karin revised my diet, added short-term corrective supplements, and monitored my progress until we achieved the desired outcome. She is a brilliant and compassionate practitioner..”
