Katie Duda

Katie Duda is an Integrative Health Practitioner, bestselling author, and mother of three whose work sits at the intersection of functional medicine, gut health, and hormone optimization for women.

After years of navigating her own health struggles — digestive distress, hormonal imbalances, fertility challenges, and symptoms that conventional medicine couldn't explain — Katie found her way through functional medicine and root-cause healing. That journey became the foundation of a practice dedicated to helping women reclaim their energy, confidence, and vitality without extreme protocols or guesswork.

Specializing in women in their 30s and 40s who are doing everything right and still feel held back, Katie uses advanced functional at-home lab testing, holistic nutrition, and personalized lifestyle strategies to uncover what's actually driving symptoms — and address it at the source. Her approach is grounded, science-informed, and built around real life.

In Fix Your Gut, Transform Your Life — her bestselling 30-day gut healing protocol with over 4,500 copies sold — Katie distills 7 years of clinical experience into a practical, accessible guide that has helped thousands of women transform their digestion, balance their hormones, and feel genuinely well in their own bodies.

As the founder of Well Within Collective, Katie continues to work with women nationwide through 1:1 coaching, educational content, and her podcast — bringing root-cause healing out of the clinical setting and into everyday life.

Her mission is simple: help women understand their bodies, heal from the inside out, and build a life that actually feels good to live in.
