Ms. Wen belongs to the “tonic family”, she usually takes deep-sea fish oil, propolis and other health products. Recently, she felt tired and weak one after another and lost her appetite. The hospital examination revealed that her liver was not good and her transaminases were elevated. The doctor told her that this is the liver damage caused by taking health care products indiscriminately, and it is directly related to her usual unscientific large amount of supplements. If she didn’t control the amount of supplements she took, her liver function would get worse and worse, and eventually it might develop into fatty liver and cirrhosis. She was very puzzled, “I take health supplements to strengthen my body, how can I get sick instead?” Most people through the normal diet, the body does not have a serious lack of various nutrients, in this case, if the daily dose of vitamins, trace elements, etc., most can not be effectively absorbed, to be metabolized by the liver decomposition out of the body, which is undoubtedly greatly increased the workload of the liver. And iron, vitamin A and D, etc. intake too much can not be excreted, there is a risk of accumulation in the liver to lead to cirrhosis, hepatosplenomegaly and other toxic reactions. Before preparing to take a supplement, you must consult your doctor or have a comprehensive medical checkup to see if you really need a supplement; if you need to take health supplements, you should not take large doses or for a long time.
