Taking DHA in normal doses is generally harmless, but if overdosed over a long period of time, it may be taxing on the kidneys. DHA (docosahexaenoic acid) is an important component of the brain and retina, suitable for pregnant women and children during development. It can effectively promote the neural development of the fetus, and it can improve high blood pressure as well as high blood sugar in pregnant women, and it can promote the development of intelligence in children. However, excessive consumption is generally not recommended because excessive consumption of DHA may burden the kidneys, which is not conducive to the health of the organism. In order to ensure the development of pregnant women as well as the fetus, it is recommended to try to take in the DNA needed by the organism through diet, or take DHA under the advice of a doctor to ensure the normal needs of the body. In daily life, it is recommended to eat some nutritious and light food, such as egg soup, pork liver, lean meat porridge, milk, broccoli, bananas, etc., to ensure that the diversity of food is conducive to the health of the body.
