The Unique Way How to Achieve Optimal Health in Your 40s w/ Erin Gagne, FNP-BC
Today’s episode is hands down the best resource on the podcast for any woman approaching 40, in her 40s, or beyond! My guest, Erin Gagne, shares invaluable insights on hormone health, perimenopause, supplements, stress management, fitness, and so much more. Grab a pen and journal because you’re going to want to take notes!
This is Erin’s second time on the show & if you missed her the first time I highly recommend scrolling back & giving it a listen (I’ll link it below). We covered women’s hormone health, birth control, functional medicine, and the spiritual aspect of healing.
Erin is a board-certified Family Nurse Practitioner and Functional Medicine Practitioner specializing in hormone therapy and metabolic health. With over a decade of experience, she helps men and women—especially those in perimenopause and menopause—reclaim their vitality through a holistic, personalized approach.
Having healed from early-onset hormonal imbalances herself, she brings both expertise and personal insight to her work. Erin’s practice offers comprehensive hormone replacement therapy (HRT), including bioidentical hormones, peptides, and thyroid management.
In This Episode, We Discuss:
-
Perimenopause: what it is, why it’s not something to fear, and how to support your body through this transition.
-
Deep dive into hormone health: specific tests, symptoms, protocols, and treatment options.
-
Thyroid health and its impact on energy, metabolism, and overall wellness.
-
The importance of muscle (the organ of longevity) and how to build it effectively.
-
The chronic stress, under-eating, high cortisol, weight gain cycle and how to break free.
-
Debunking myths and wellness trends in both Eastern and Western modalities.
-
Must-do wellness practices for women in their 40s.
-
Why it might be time to ditch alcohol.
-
The best workouts for women in their 40s (spoiler: it’s not the same as in your 20s!).
-
Supplements: common deficiencies, the role of methylation, trusted brands, and proper dosages.
-
Semaglutide & GLP-1s: how they work and the role of stress in insulin resistance.
-
The importance of mindset, personal responsibility, and the quality of our relationships in our health journey.
And so much more! Erin is a wealth of knowledge, and I highly recommend her services. My mom worked with her and loved it, and as soon as I get my blood work done I’m going to work with her too! She also takes virtual patients, which is perfect if you're not in South Carolina.
