Nature Had It First explains what may be happening inside your body when you live with an autoimmune or hormonal condition, so you can have a better conversation with your doctor.
Find your condition
Each condition page explains the research in plain words and gathers our videos in one place.
Get a free tracker
A week of tracking shows patterns that a single appointment can’t. Choose the Prep Pack if you’re not sure.
Bring your questions
Every video ends with questions for your doctor. Write them down and take them with you to your next visit.
What we are, and what we aren’t
We are a mother and daughter who have lived with autoimmune illness in our family since 1992, and the authors of two books. We read the research so you don’t have to start from zero.
We are not doctors. We don’t diagnose, treat or sell supplements, and we’ll never tell you to stop a medication. Read how we research.
One email a week, in plain language
