This isn’t one-size-fits-all nutrition advice
It’s a personalized path forward, led by a team that sees the full picture
I help women finally understand what the conventional system misses—and use food as medicine to reduce inflammation, balance hormones, and feel good again.
You’re not crazy. You’re just missing answers
When she’s not diving into research or leading community challenges, you’ll find her hiking with her husband and two kids, sourcing the best seasonal produce at the farmer’s market, or making a blood sugar-balanced smoothie.
Her work has been featured on The Today Show, ABC News, Oprah, Women’s Health Magazine, Yahoo, and Mind Body Green.
Brigid Titgemeier, MS, RDN, LD, IFNCP is a leading expert in women’s health and a functional registered dietitian with over a decade of experience helping thousands of women—including leaders like Fortune 500 CEOs, senators, and bestselling authors—reverse chronic symptoms through strategic nutrition and real data.
Board Certified in Integrative and Functional Nutrition and holding a Master’s in Public Health Nutrition from Case Western Reserve University, Brigid helped launch the Cleveland Clinic Center for Functional Medicine under Dr. Mark Hyman and serves as an adjunct instructor at Case Western’s School of Medicine, where she co-created and teaches the Integrative and Functional Nutrition curriculum.
Her approach blends clinical precision with real-world practicality, going beyond rigid protocols to deliver sustainable change that actually sticks
Functional nutrition - before it was trending
She knew there was a more comprehensive way to help women heal..
Or worse: “This is just part of aging.”
So she built IT
Smart, capable women being told they were “normal” when their intuition said otherwise.
Or that they were “just stressed.”
Because that’s what Brigid kept seeing:
It’s about fixing what the conventional system keeps ignoring—like why you feel awful even when you’re “doing everything right.”
But this isn’t about impressing you with credentials.
Because Women Deserve Better
It’s about helping women finally feel like themselves again.
It’s not about chasing a perfect diet or obsessing over every number.
This is where our work lives—bridging clinical insight with doable daily systems.
She saw women dismissed, overwhelmed, and drowning in protocol perfectionism … when what they really needed was a way forward that worked in real life.
When Brigid first entered the world of functional medicine, she was struck by the gap:
Great theory, beautiful science—but very little day-to-day support.
Symptom relief shouldn’t require a pill for every ill.
