Cognitive Fuel Source

Meaning

Cognitive Fuel Source refers to the essential energy substrates utilized by the central nervous system to power continuous, high-demand neuronal activity, signaling, and cellular maintenance. While glucose is the brain’s primary metabolic fuel, alternative molecules like ketone bodies become crucial energy providers during states of fasting or carbohydrate restriction. Ensuring a consistent, efficient, and flexible supply of these energy molecules is paramount for sustaining executive function, attention span, and complex memory processes. Insufficient or unstable fueling is a direct contributor to common symptoms like mental fatigue and cognitive fog.
