Brain Fog & Mental Energy

Brain fog isn't "just stress."
It can be a cellular energy problem.

Your brain is the most energy-hungry organ you have — and its neurons run almost entirely on mitochondrial ATP. When cellular energy production dips, mental clarity is often one of the first things to go. mescreen™ measures how efficiently your mitochondria are producing that energy.

The mitochondrial connection

Though it's only about 2% of your body weight, your brain consumes roughly 20% of your energy. Neurons are among the most mitochondria-dense cells in the body for exactly this reason. When mitochondrial output falls, the brain feels it quickly — as fog, slow recall, and difficulty focusing. Most cognitive workups never measure this directly.
