About Rachel
Bio
Rachel Swanson, MS, RD, LDN doesn’t do generic wellness advice. She architects peak human performance.
As Nutrition Director at LifeSpan Medicine and founder of Diet Doctors, LLC, Rachel works at the intersection of cutting-edge science and elite health optimization. Most recently, she turned that lens on fertility. Her debut book TRYING! (2026) distills 400+ studies into a roadmap for reproductive health that the field has been missing.
Rachel holds an MS in Clinical Nutrition from NYU, trained at Mt. Sinai, and completed functional medicine training through IFM.
When she’s not rewiring how people think about food and longevity, she’s writing checks as an angel investor in wearable tech and women’s health.
