Allara's nutrition evidence library
What is Allara's PCOS Nutrition Evidence Library?
The Allara PCOS Nutrition Evidence Library is a carefully curated collection of scientific studies, clinical guidelines and Allara-created guides that provide the foundation for our nutritional recommendations. We prioritize evidence-based research to ensure that every suggestion we make is grounded in the latest scientific understanding, supporting women with PCOS on their journey to better health.
Allara’s Evidence-Based PCOS Diet & Nutrition Programming
We pride ourselves on providing evidence-based PCOS management and treatment, including our Registered Dietitians (RDs). We built our nutrition program on a strong foundation of continuous literature review. That means all the information shared with patients has research to back it up. The articles and studies that inform recommendations are evaluated not just for their content but also for their overall quality and reliability.
As new studies, findings, or scientific understandings arise, the body of evidence Allara uses may change as well. This means: Yes, our recommendations may change over time, and we are proud of that. We will always seek to provide you with the most up-to-date, exceptional-level care.

PCOS Nutrition FAQ
What is the PCOS diet?
Don’t think of this as yet another diet. We work with our patients to instill sustainable, healthful eating and lifestyle habits that are proven to support their PCOS and hormonal health goals.
What is a healthy diet for polycystic ovary syndrome?
The Allara approach to PCOS nutrition is highly personalized. Our dietitians work with each patient to find a healthful, sustainable, and whole-foods approach to eating and thriving with PCOS.
Can you recommend a PCOS meal plan?
We collaborate with each patient on an overall wellness strategy that often includes evidence-based meal plans and recommendations.
What is the best diet for PCOS?
There is no “best diet” for PCOS, as everybody is unique and has different needs.
Do you recommend supplements for PCOS?
People with PCOS are at higher risk of nutritional deficiencies, so a combination of a whole-food diet and supplements, such as Inositol and a good multivitamin, can help you meet your macro- and micronutrient goals.
“I was given an explanation of how my hormonal imbalance was affecting me as a whole - body & mind - & tools so that we could start to manage my condition. I am happy to announce after a year of trying, I found out that I was pregnant & I couldn’t be happier!”
“This is genuinely the first time in my 7 years of being diagnosed, that I have felt seen and heard.”
“The Allara Community gives me the courage and support to continue my PCOS journey - I am never afraid to ask the hard questions and love hearing from other women with the same challenges.”
"My doctor went above and beyond making sure I had all the necessary tests, but also tremendously helped me in understanding my diagnosis, helping me change my lifestyle, and making sure I get the treatment I deserve."
"Before Allara I had no real direction or understanding of what it meant to have PCOS. Now I have a team of people that take time to explain every single thing to me, ask me how I feel and let me be a part of my treatment plan."
