RTRX 2025

Turning Possibilities Into Real Action

Dr. Weston hosting a masterclass at RTRX 2025

Our very own Dr. Marguerite Weston took the stage at RTRX for a second year in a row. This time, she followed up her talk with hands-on functional strength testing and one-on-one engagement. With a renewed focus on metabolic health and actionable knowledge, the Donaldson presence this year turned inspiration into movement and possibility into personalized insight.

The Masterclass: “Creating Possibilities For Your Health”

Dr. Weston challenged attendees to take a proactive look at their long-term health. She explored how the body’s nutritional needs evolve and how today’s common health struggles (like IBS and vitamin D deficiency) reflect modern lifestyle challenges.

By demystifying lab work and connecting daily habits to lasting outcomes, she empowered attendees to take real steps toward extending their healthspan.

Key Takeaways From Her Session Included:

  • Understanding optimal lab ranges for metabolic health

  • How to interpret lab results to better advocate for yourself

  • Lifestyle shifts that support methylation and long-term vitality

  • The role of hormones, why they change and how they affect overall health

  • Brain health strategies, including dementia prevention and reducing “brain fog”

  • Supplements and lesser-known “healthspan hacks” worth exploring — & which to ignore

  • The difference between functional medicine and conventional medicine, and why prevention matters

The Longevity Circuit: 5 Tests To Gauge Your Metabolic Age

Attendees engaged with their metabolic health through movement-based assessments as part of our 5-part Longevity Circuit. The circuit was designed to provide insight into how the body is functioning today and how it may age over time, through the use of dorsiflexion lunges, grip strength testing, dead hangs, jumping power measurements and pulling strength.

Dr. Weston brought her functional medicine team along to guide the experience, with experts on hand to help attendees interpret their results and offer practical strategies for improvement.
