Meet Catharine Arnston: The Woman Who Unlocked the Power of Algae

Catharine Arnston is the founder and Chief Scientific Officer of ENERGYbits®, a wellness company on a mission to help people feel, look, and live better—naturally. But her journey into the world of algae didn’t begin in a lab or a boardroom—it began with love, family, and a life-changing diagnosis.

In 2009, Catharine’s younger sister was diagnosed with breast cancer. As she supported her sister through treatment, Catharine turned to holistic nutrition to aid her recovery. While researching plant-based foods recommended by her sister’s oncologist, Catharine stumbled upon one of the world’s most powerful superfoods—algae.

What began as a personal quest quickly grew into a professional calling. Fascinated by the unparalleled nutrient density and healing potential of algae, Catharine left her corporate career, went back to school for nutrition, and devoted over a decade to studying the science behind spirulina and chlorella. Her passion, dedication, and relentless curiosity led to the creation of ENERGYbits®—a line of premium algae tablets that offer clean, plant-based energy, beauty, detox, and longevity.

As the Founder & CEO of ENERGYbits®, Catharine has spent 15+ years researching algae’s incredible benefits—from boosting energy and mental clarity to reversing aging at the cellular level. She has written hundreds of papers, given lectures at 30+ national medical conferences, spoken on 300+ podcasts and built ENERGYbits® into a highly respected global brand.

Today, Catharine is recognized as one of the leading experts in algae nutrition, empowering people around the world to reclaim their health—one tiny tablet at a time. Her story is one of compassion, purpose, and the belief that nature holds the key to our well-being.
