Caitlin Johnson
PCOS & Fertility Dietitian and PCOS patient — creator of The PCOS App and PCOS Formularies with 52K+ followers
Caitlin Johnson is a registered dietitian who wears many hats in the PCOS world: she is a PCOS patient herself, a fertility-focused PCOS dietitian, the creator of The PCOS App, and the founder of PCOS Formularies. With over 52,000 Instagram followers at @pcosfertilitynutrition, she has built a platform rooted in both personal experience and clinical expertise.
The PCOS App — which Caitlin created — is a digital tool designed specifically for women with PCOS to track symptoms, access PCOS-friendly meal plans and recipes, and monitor their fertility journey. The fact that it was built by a PCOS dietitian who is also a PCOS patient gives it a depth and specificity that generic health apps lack.
Through PCOS Formularies, Caitlin provides evidence-based supplement guidance tailored specifically to PCOS and fertility. Her clinical content covers ovulation induction nutrition, fertility-supportive eating patterns for PCOS, and how to optimize hormones for conception.
Caitlin's content at @pcosfertilitynutrition is particularly valuable for women navigating the intersection of PCOS and fertility — one of the most emotionally and practically complex aspects of the condition. She brings clinical credibility, personal relatability, and practical tools that few others in the space can match.
