Nervonic acid is primarily used in the development of treatments for neurological disorders due to its role in the synthesis of sphingolipids, which are crucial components of the myelin sheath in nerve cells. It is being researched for its potential to support myelin repair in conditions like multiple sclerosis and other demyelinating diseases. Additionally, it is incorporated into dietary supplements aimed at improving cognitive function and brain health. In cosmetics, nervonic acid is valued for its skin-repairing properties, helping to enhance skin barrier function and hydration. Its applications also extend to the study of metabolic diseases, where it is explored for its lipid-regulating effects.
