Aging Is Natural, Declining Is Not: The Algae Science Most Doctors Miss

She's 70 years old, holds a PhD she earned in her late 60s, and looks like she cracked the code on aging. But Dr. Catharine Arnston isn't selling a beauty secret she's sharing 17 years of research into two of the most scientifically documented superfoods on Earth: spirulina and chlorella.In this episode of SHE MD, Mary Alice Haney and Dr. Aliabadi sit down with Dr. Catharine Arnston, Chief Scientific Officer of ENERGYbits, for one of the most eye-opening conversations we've had on this show. It started with her sister's breast cancer diagnosis and a pivot away from a 25-year corporate career. What she found in the research changed everything she thought she knew about energy, brain health, aging, and women's bodies.This isn't wellness fluff. There are over 100,000 peer-reviewed studies on these two algae. NASA has been feeding them to astronauts for 50 years. The United Nations endorsed spirulina as the answer to world hunger. And yet most women in the Western world have never heard of them.

Dr. Catharine Arnston is the founder and Chief Scientific Officer of ENERGYbits, the medical-grade algae company she launched 17 years ago after pivoting from a 25-year international corporate career to research plant-based nutrition for her sister, who had been diagnosed with breast cancer. Her research led her to spirulina and chlorella, two microalgae backed by more than 100,000 scientific studies, and to a mission of bringing clean, hand-sourced algae nutrition to women, families, and elite athletes around the world. Catharine earned her health coaching certificate from the Institute for Integrative Nutrition and went on to complete her PhD in her late 60s, becoming one of the most credentialed and outspoken advocates for algae nutrition in the world. Her upcoming book, Love Your Health to Bits with Algae, set for an October release, distills 17 years of research into accessible, "science with sarcasm" guidance for the everyday reader. Catharine lives by the philosophy that "aging is natural, declining is not" and is on a mission to make algae as common in the Western world as it has been in Asia for the past 60 years.
