Do pregnant women have to eat DHA?

My best friend has been taking dna when she was pregnant. I am also pregnant now. I don’t know if I should supplement it. Do pregnant women have to eat dha?

Pregnant women do not necessarily need to eat DHA. DHA is an essential polyunsaturated fatty acid, which is contained in most foods, such as salmon, saury, sardines, hairtail, etc. If there are no bad habits such as partial eclipse or picky eaters during pregnancy. If the human body continues to take in enough nutrients, it is not necessary to supplement DHA. However, if pregnant women cannot take in enough DHA by adjusting their diet, they need to take nutritional supplements reasonably according to the doctor's guidance. During pregnancy, they should go to the hospital for check-ups regularly to monitor the growth and development of the fetus.
