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 will retire 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 Dr. Sharon Yeh

For those seeking a new practitioner, I am honored to recommend Dr. Sharon Yeh, PharmD, MS, CNS.

Dr. Yeh trained directly with me for over 4 years, mastering advanced biochemistry, functional lab interpretation, and client-centered care. She shares the same dedication to uncovering root causes and designing personalized protocols that transform health.

What Sets Dr. Sharon Yeh Apart

With over 20 years of experience as a clinical pharmacist and advanced training in functional medicine and nutrition—including a Doctor of Pharmacy degree, a Master’s in Functional Medicine & Nutrition, and 1000+ hours of clinical mentorship to earn her Certified Nutrition Specialist® credential—Dr. Yeh brings both depth and precision to her practice.

She also holds NGH-certified hypnosis training, enriching her toolset with mind-body techniques that engage healing on a deeper level.
