Nervonic acid is primarily utilized in the field of health and nutrition due to its significant role in brain function and development. It is a key component in the synthesis of nerve cell myelin, which is essential for the proper transmission of nerve impulses. This makes it valuable in dietary supplements aimed at supporting cognitive health, particularly in aging populations or individuals with neurological disorders.

In the cosmetic industry, it is incorporated into skincare products for its moisturizing and skin barrier-enhancing properties. It helps in maintaining skin elasticity and preventing moisture loss, making it beneficial for anti-aging formulations and treatments for dry or damaged skin.

Additionally, nervonic acid is being explored in medical research for its potential therapeutic applications in treating diseases like multiple sclerosis and adrenoleukodystrophy, where myelin repair is crucial. Its role in lipid metabolism also makes it a subject of interest in studies related to metabolic disorders and cardiovascular health.
