What would you do if you were told you had anywhere from 10 minutes to 10 years to live?

In this episode, Dr. Barrett sit down with Samuel Shepherd, biochemical engineer, who shares his personal journey after being diagnosed with polycythemia vera, a rare blood disorder, and how that diagnosis led him to investigate the role of oxidative stress, free radicals, and cellular damage in chronic disease.

His research led him to study astaxanthin, a powerful carotenoid found in nature, and how it may influence inflammation, mitochondrial health, and oxidative balance at the cellular level.

This is not a typical supplement conversation. It's a deep dive into biochemistry, reactive oxygen species (ROS), protein misfolding, and immune signaling—and how these processes may be involved in conditions like cancer, diabetes, and neurodegenerative disease.

In this episode, we discuss:

➡️How oxidative stress and free radicals damage DNA and proteins
➡️The role of mitochondria and inflammation in chronic disease
➡️Why antioxidant defenses decline with age
➡️How protein misfolding may contribute to insulin resistance
➡️Why astaxanthin has become a major focus of his research

⚠️ Important: This episode is for educational discussion only and does not replace medical care. Cancer and chronic disease require professional diagnosis and treatment. Always consult qualified healthcare providers before making medical decisions.

If you're interested in biochemistry, longevity research, inflammation, and cellular health, this conversation will give you a new way to think about why disease develops—and what future research may reveal.
