Hi, I’m Claire Margolf, a Registered Dietitian based in Denver, Colorado and Integrative & Functional Nutrition Certified Practitioner specializing in women in perimenopause and menopause.
My practice, Nutrition With You, is built on a simple premise: the foundation a woman builds during perimenopause directly shapes her long-term risk for cardiovascular disease, osteoporosis, cognitive decline, and metabolic dysfunction.
That window matters and it is consistently underserved. I work at the intersection of functional nutrition, and the metabolic and biological shifts women experience during this transition, bridging the gap between a patient's clinical picture and a nutrition plan that actually addresses it.
I’m glad you’re here.
I specialize in women in their 40s and early 50s navigating the metabolic and hormonal changes of perimenopause through a functional, lab-based approach.
I'm often asked whether I work with women who are already postmenopausal in their 60s and beyond. The answer is yes. While the hormonal landscape changes after menopause, many of the same underlying drivers remain: metabolic health, body composition, inflammation, gut function, and how the body is processing and responding to hormones over time.
This means the work doesn't stop at menopause. In many ways, this stage becomes even more important for supporting long-term health, preserving muscle mass, and reducing cardiometabolic risk.
Who I Work With
After completing my clinical training and working in a hospital setting, I saw firsthand how much of our healthcare system is built around managing disease once it has already progressed. There is a place for that care, but very little time is spent asking why symptoms are happening in the first place, or how to intervene earlier. I'm a wife and mom of a teen and a preteen, living the same season of life as many of the women I work with.
Over the years, I've watched close friends in their 40s and 50s change in ways they couldn't explain. Some were on HRT and some weren't, but their stories sounded the same: weight changes, hair loss, mood shifts, and sleepless nights. Sharp, confident women who started feeling like strangers in their own bodies.
One friend told me something I haven't forgotten: "I no longer speak up in meetings because I've lost the confidence that I can find the words." I've had my own quiet moments too. Enough to understand how disorienting this transition can be, and how much it matters to have someone in your corner who truly gets it. I wanted to be the practitioner I kept wishing existed for the women in my life.
