Is omega-3 DHA

Omega-3 is not DHA, but DHA is a type of omega-3 fatty acid. Omega-3 fatty acids mainly include alpha linolenic acid, eicosapentaenoic acid, and docosahexaenoic acid, among which docosahexaenoic acid is DHA. Omega-3 fatty acids are a group of polyunsaturated fatty acids that are crucial for human health, mainly including three types. Alpha linolenic acid is mainly present in plant-based foods such as flaxseed oil and walnuts, and can be partially converted into EPA and DHA in the body. Epidocosapentaenoic acid is mainly derived from deep-sea fish and has anti-inflammatory and blood lipid regulating effects. Docosahexaenoic acid is an important component of the brain and retina, playing a crucial role in the neurodevelopment of infants and young children and cognitive function in adults. DHA, as an important member of the omega-3 family, has unique physiological functions. DHA accounts for approximately 15-20% of the weight of the cerebral cortex and is an important substance for the growth and maintenance of nervous system cells. DHA can also promote the development of retinal photoreceptors, and deficiency may lead to delayed visual development. Compared to other omega-3 fatty acids, DHA has a higher concentration in the nervous system and a more specific effect.

It is recommended to obtain omega-3 fatty acids through a balanced diet and consume deep-sea fish 2-3 times a week. Pregnant women, pregnant women, lactating women, and infants can increase their intake of DHA appropriately. When choosing supplements, attention should be paid to distinguishing the efficacy of different types of omega-3 and using them under the guidance of professionals. Maintaining a healthy lifestyle and engaging in moderate exercise can help improve the utilization efficiency of omega-3 fatty acids.
