1330. Why you absolutely MUST take algae daily to protect your longevity

In this episode of The Human Upgrade, Host Dave Asprey sits down with Catharine Arnston, PhD, founder of ENERGYbits and a leading voice in algae research and functional medicine. Entering her 70th year with the energy, skin, and cognition of someone decades younger, Catharine is living proof of what happens when you care for your mitochondria. Together they unpack why mitochondrial decline accelerates after age 30, how superoxide dismutase (SOD) and glutathione protect against cellular aging, and why spirulina and chlorella are uniquely powerful for energy, detox, and resilience. You’ll hear practical strategies for using algae to optimize brain performance, metabolism, and longevity—plus insights on diet, hormones, and the hidden biological “programming” that makes aging optional. Built for listeners who care about biohacking, hacking human performance, and functional medicine, this conversation connects mitochondria with real-world energy, resilience, and lifespan upgrades.

Your mitochondria are the power plants of your cells, and when they break down, you lose energy, brain sharpness, and resilience against aging. In this episode, you’ll learn how to hack your mitochondria to supercharge human performance, prevent decline, and extend longevity with tools that are natural, effective, and backed by decades of research. 

 

Host Dave Asprey sits down with Catharine Arnston, founder of ENERGYbits, recent PhD graduate, and one of the world’s top experts on algae and functional medicine. Entering her 70th year without medications, with the cognition to finish a doctorate, and the health markers of someone decades younger, Catharine is living proof of how mitochondria and nutrition shape aging, brain optimization, and resilience. 

 

Together they break down why mitochondria fail after age 30, how algae works as a master supplement to restore superoxide dismutase (SOD) and glutathione, and what happens when you give your cells the nutrients they’re wired to need. They uncover how mitochondria connect to energy, inflammation, metabolism, and cellular resilience. This is a masterclass in hacking energy and longevity, built for people who want to upgrade every system of the body and mind. 

 

You’ll learn: 

  • Why mitochondria decline after age 30 and how to stop it
  • The role of superoxide dismutase (SOD) and glutathione in preventing cellular “rust”
  • How spirulina and chlorella outperform most supplements for detox and energy
  • The connection between mitochondria and brain optimization
  • Why men’s higher iron levels accelerate aging and how algae helps balance it
  • The real link between metabolism, inflammation, and longevity
  • How to build a mitochondria-first biohacking stack that actually works

 

This is essential listening for fans of biohacking, hacking human performance, functional medicine, and longevity who want actionable tools from Host Dave Asprey and a guest who embodies what it means to age with energy, clarity, and vitality.
