The main differences between dha and nervonic acid are different body compositions, different production methods, and different effects.

1. Different ingredients: DHA is the abbreviation of docosahexaenoic acid, a type of unsaturated fatty acid, and nervonic acid is an intermediate product produced during the metabolism of tyrosine, so DHA The main components of nervonic acid and nervonic acid are unsaturated fatty acids.

2. Different production methods: DHA is mainly supplied through food, such as marine fish, walnuts, peanuts, sesame seeds, and deep-sea fish. These foods all contain DHA. Nervonic acid is mainly extracted from fruits, vegetables and grains, and can also be converted into DHA or EPA in the human body.

3. Different functions: The function of DHA is to promote the growth and maintenance of nervous system cells, help brain cell development, repair nervous system functions, and prevent dementia and stroke. The function of nervonic acid is to increase the excitability of cerebral cortex cells, maintain the stability of the nervous system, and prevent neurasthenia and amnesia.

4. Both DHA and nervonic acid have good health care functions. They can be supplemented by eating more fish and nut foods on a daily basis, as well as eating more protein-rich foods, such as eggs, milk, etc. , to ensure nutritional balance.
