Catharine Arnston on Spirulina, Chlorella, Mitochondria, Detox, Brain Energy, and Longevity&nbsp;Visit&nbsp;<a href="https://energybits.com/" rel="noopener noreferrer" target="_blank">https://energybits.com/</a>&nbsp;and use code&nbsp;HUMANUPGRADE&nbsp;for&nbsp;20% off.&nbsp;Could one of the oldest foods on Earth also be one of the most overlooked tools for mitochondrial health, brain function, detoxification, and longevity?&nbsp;Host Dave Asprey sits down with Catharine Arnston, founder of ENERGYbits and author of&nbsp;Love Your Health to Bits with Algae, to explore the biology of spirulina and chlorella and why these microscopic organisms have been studied for decades as unusually nutrient-dense foods.&nbsp;Catharine explains the major differences between spirulina and chlorella, from how they are grown and processed to how she uses them for completely different purposes. Spirulina contains compounds including phycocyanin and superoxide dismutase that Catharine believes can support mitochondrial function, antioxidant defenses, cellular energy, and brain health, while chlorella is used primarily for binding and removing unwanted compounds such as heavy metals. They also discuss why water quality, sourcing, drying temperature, and processing can dramatically change the final product.&nbsp;The conversation goes deep into mitochondrial biology, including the electron transport chain, ATP production, oxidative stress, free radicals, cytochrome c, superoxide dismutase, and the blue pigment phycocyanin. Dave connects these mechanisms to his own experience rebuilding mitochondrial function and explains why increasing cellular energy without adequate antioxidant defenses may create problems, particularly for people experimenting with advanced longevity interventions such as mitochondrial peptides.&nbsp;Dave and Catharine also explore methylene blue, psychedelics, exercise, brain aging, environmental toxins, nutrient density, food quality, algae farming, sustainable agriculture, and why maintaining mitochondrial function may become increasingly important with age. Catharine, who turns 70 shortly after the recording, also shares the philosophy behind her first book and her belief that aging does not have to mean accepting declining energy and cognitive function.&nbsp;This is essential listening for anyone interested in mitochondria, spirulina, chlorella, cellular energy, brain health, detoxification, oxidative stress, longevity, biohacking, nutrient density, methylene blue, peptides, and maintaining performance as you age.&nbsp;You’ll Learn:&nbsp;<ul><li>Why spirulina and chlorella work differently in the body&nbsp;</li><li>How spirulina may support mitochondrial energy and antioxidant defenses&nbsp;</li><li>Why chlorella is commonly used for heavy metal and toxin binding&nbsp;</li><li>What phycocyanin and superoxide dismutase do inside cells&nbsp;</li><li>How oxidative stress can disrupt mitochondrial energy production&nbsp;</li><li>Why Dave cautions against pushing mitochondrial output without adequate cellular protection&nbsp;</li><li>How algae may support brain health, longevity, and performance as you age&nbsp;</li></ul>&nbsp;Dave Asprey is 4x NY Times Bestselling Author, Longevity Expert and Creator of the Biohacking Movement.
