Neural Fuel

Meaning

Neural fuel is a term used to describe the array of metabolic substrates and essential micronutrients that directly support the energy production and optimal function of neurons and glial cells in the central nervous system. While glucose is the brain’s primary energy source, the concept also encompasses alternative substrates like ketones and critical cofactors such as B vitamins and essential fatty acids. Adequate and stable neural fuel is crucial for maintaining cognitive clarity, mood stability, and the precise regulation of the neuroendocrine axes.
