Level 1: What is DHADHA? It is an Omega-3 fatty acid and an essential nutrient for the human body. It plays a very important role in brain and eye development and also helps maintain cardiovascular health. However, the human body cannot synthesize DHA on its own and needs to be consumed through food or nutritional supplements. Pregnant women need to increase their DHA intake during pregnancy because the fetus\’s brain and retina require a large amount of DHA to support their normal development. In addition, pregnant women themselves also need enough DHA to maintain cardiovascular health and prevent postpartum depression, etc.
