Vitamin D has long been associated with bone health—but emerging neuroscience suggests its role goes far beyond that.

In this episode, we explore how the so-called “sunshine vitamin” may influence brain structure, cognitive function, and long-term mental health outcomes.

From its role as a neurosteroid regulating hundreds of genes to its connection with depression, ADHD, and dementia risk, the data is beginning to paint a much bigger picture.

We also unpack:
✔ Why midlife Vitamin D levels may impact brain health decades later
✔ The link between geography, sunlight exposure, and mental health risk
✔ The surprising reality of widespread deficiency—even in sunny regions

As research continues to evolve, one question becomes hard to ignore:

Are we underestimating the role of Vitamin D in shaping brain health across the lifespan?
