Neuronic acid is a core natural component of brain nerve fibers and cells, and is an essential nutrient for brain development and maintenance. It plays a significant role in improving the activity of brain nerves and preventing brain nerve aging. The naturally extracted nerve acid is added as an active ingredient in health food or cosmetics to infant, young or elderly formula. In addition, products with added neurotransmitters are more suitable for people with brain diseases such as stroke sequelae, Alzheimer's disease, cerebral palsy, brain atrophy, memory loss, insomnia, and forgetfulness.
