One cup of blueberries a day can improve vascular function, support the aging brain, and tighten glucose control in ways that go far beyond antioxidant activity. In this episode, Dr. Rhonda Patrick breaks down how blueberry anthocyanins and their downstream metabolites act as signaling molecules that support endothelial function and memory, while long-term studies link regular blueberry intake to slower cognitive decline and lower dementia risk. She also details the evidence for post-meal glucose control and insulin sensitivity, and explains why blending blueberries with bananas may reduce polyphenol availability.

The next 10 years may add decades to human lifespan by compressing the time it takes to understand, treat, and prevent disease. In this episode, Dr. Derya Unutmaz explains why accelerating AI could transform drug discovery, shorten clinical trials, and push cancer treatment toward increasingly personalized interventions. He also reframes AI not as an existential threat, but as a medical enabler that doctors may soon be ethically obligated to use.

Many symptoms attributed to aging are also consistent with chronic inflammatory stress and impaired NAD metabolism. Dr. Charles Brenner explains the mechanisms, the human data, and what interventions actually move the needle. He also cuts through the crowded world of NAD boosters, including oral NAD pills, NMN, NR, and NAD IV drips, clarifying what actually raises NAD in humans and what emerging research suggests about NR for lowering inflammation and improving recovery.
