GAIL CLAYTON, DCN, CNS, MS, RPh, LDN

A Pharmacist Turned Functional Nutrition Expert
For over 25 years, I worked as a clinical pharmacist before pursuing advanced training in functional nutrition. My passion has always been helping people uncover the root cause of complex health challenges and supporting healing through evidence-based, natural approaches.

The Next Chapter: Retirement
As of the end of 2025, I retired from accepting new clients. I will continue to provide follow-up appointments for existing clients through 2026.

But my work doesn’t stop here. My mission continues through teaching and mentoring. I now focus on educating practitioners and health seekers through my courses on Organic Acids, Amino Acids, Mold Detox, and more.

Trusted Care with Carpathia Collaborative

While Drs. Christensen & Clayton primarily focus on education, practitioner training, and advancing systems-based approaches to complex chronic illness, individuals seeking clinical care may connect with the team at Carpathia Collaborative
