## Resource

What if the fatigue, brain fog, and loss of strength many women experience after 50 are not simply hormonal, but reflect deeper shifts in metabolism, muscle, and mitochondrial function? In this insightful episode, Dr. Elizabeth Goldspink reframes midlife as a metabolic and neurological transition rather than a purely hormonal one. She explains how muscle acts as a longevity organ, how mitochondrial efficiency impacts both energy and cognition, and how targeted lifestyle and nutrition strategies can restore resilience. This empowering conversation offers practical, science-informed steps to help women take control of how they age. Dr. Elizabeth Goldspink is a naturopathic doctor, women's health researcher, and founder of Wellex . She has more than 16 years of clinical experience supporting women's hormonal, metabolic, and immune health. Dr. Goldspink is a published author in peer-reviewed medical journals and has completed advanced training in mind-body medicine at Harvard University . Her work focuses on translating complex scientific research into practical, personalized health strategies. She has helped thousands of women restore energy, resilience, and long-term well-being. Her current focus is on evidence-based supplementation and metabolic health optimization for women in midlife and beyond.
