Brain Fog, Cognitive Function, and Longevity

Brain fog is one of the most common concerns people describe, yet it’s often dismissed.

This is something we hear all the time—and it’s rarely just “in your head.”

Brain fog is often connected to sleep disruption, insulin resistance, inflammation, and hormone imbalance.

It is usually not a single issue, but a pattern.
