Why You're Only Absorbing 10% of the Protein You Eat | Catharine Arnston PhD

In this episode of 'Hydrate with Tracy Duhs,' host Tracy Duhs welcomes Dr. Catharine Arnston, a PhD and founder of EnergyBits, to discuss a critical yet overlooked issue: most people absorb only about 10% of the protein they consume due to poor digestion, low stomach acid, and cellular inefficiencies. Dr. Arnston reveals that algae—specifically spirulina and chlorella—offer a revolutionary solution. Unlike animal or plant proteins that require days to break down into absorbable amino acids, algae proteins are already in amino acid form and are 99% bioavailable, absorbed in seconds to minutes. Spirulina, a cyanobacteria, is particularly powerful due to its high protein content (64%), complete amino acid profile, and unique blue pigment called phycocyanin, which supports cellular energy, induces apoptosis in cancer cells, and inhibits tumor angiogenesis. Chlorella acts as a natural detoxifier, removing heavy metals, pesticides, and radiation, while also promoting bowel health. The conversation emphasizes that true health isn't just about eating protein, but about ensuring the body can absorb and utilize it—especially in the context of aging, intermittent fasting, and modern toxin exposure. Dr. Arnston shares personal motivation from her sister’s breast cancer journey and her mission to make algae accessible as a foundational, effortless, and intelligent food for optimal health.
