Most people try to fix brain fog and focus issues with caffeine or nootropics, but those approaches only mask the problem.

This video explains that brain fog begins when the brain’s energy system—its mitochondria—starts to fail, long before any obvious signs of aging appear.

Modern stress, poor sleep, artificial light, toxins, and blood sugar swings quietly drain this energy and reduce the brain’s ability to repair itself.

It then explains how methylene blue, a well-studied compound with a long medical history, works inside brain cells to improve energy production, protect neurons, and support lasting clarity when used correctly and safely.
