The speed at which a neural impulse travels is dependent on the length of the axon and the density of the axon membrane fibrils. When the axon is encased by a myelin sheath, the density of the axon membrane fibrils is increased, thus increasing the speed at which a neural impulse travels.
Myelin is a specialised cell membrane that surrounds some nerve fibres. It is formed by two main types of cells: glial cells and Schwann cells. Glial cells are named for their similarities to other types of cells, called glia, that support nerve cells (or neurons). Schwann cells are part of a nerve cell itself.
This article will discuss how to increase your myelin growth through nutrition, how to test yourself for deficiencies that may be slowing down myelin growth, and what supplements can help remedy these deficiencies.

The myelin sheath is a layer of a protective material that surrounds the axon of some glial cells. This layer assists in the transmission of neural impulses by increasing the speed at which an impulse travels.
First, the myelin sheath has a high electrical resistance, which means that it takes more time for an electrical current to travel through it than it would in a unprotected axon.
Second, the layers of myelin act like layers of insulation, preventing loss of voltage along the path of the axon.
