Episode notes

In this episode, Dr. Jockers talks with Catharine Arnston PhD about why algae may be one of the most overlooked tools for brain health, energy, and healthy aging. They unpack how spirulina delivers key nutrients that support memory, focus, and mitochondrial strength, while also helping the brain handle inflammation and oxidative stress.

Catharine explains why spirulina stands out for cognitive support, from its rich B vitamin content to its powerful antioxidant compounds that help protect neurons and cellular energy. You'll also hear how these nutrients may play a role in mental clarity, mood, and long-term brain resilience in ways most people never consider.

The conversation also dives into chlorella and its role in detoxification, especially when it comes to heavy metals and other environmental toxins that can affect both gut and brain health. As the episode unfolds, you'll learn how these two forms of algae work differently, when to use them, and why they may be a simple addition to a longevity-focused routine.
