In this episode, Professor Peter McCaffery joins Dr. Buck Joffrey to discuss the multifaceted role of Vitamin A in brain health, particularly its function as a signaling molecule that influences neuroplasticity and cognitive functions.

He elaborates on the challenges of Vitamin A supplementation, especially in aging populations, and the implications of retinoic acid signaling in neurodegenerative diseases like Alzheimer's.

The discussion also touches on the importance of skin health in the context of systemic aging and the potential for targeted therapies to enhance Vitamin A signaling without the risks associated with traditional supplementation.
