Catharine Arnston: The Power of Algae – The World's Most Nutrient-Dense Superfood

In this powerhouse episode, Darin sits down with Catharine Arnston, founder and CEO of ENERGYbits, to explore one of the planet's oldest and most potent foods — algae.
From spirulina's superoxide dismutase to chlorella's detoxifying chlorophyll, Catharine breaks down the science of why these tiny organisms hold the key to longevity, energy, detox, and cellular repair.

This episode dives deep into the microbiology of health, uncovering how microalgae could solve both human nutrition and planetary sustainability — and why spirulina may truly be "the food of the future."
