Abstract: The paper is to explore how to carry out post-market technical evaluation of dietary supplements in China by referring to the experiences at home and abroad. Experiences of major countries and regions in the post-market evaluation of similar products of dietary supplements and China’s experience in drugs were systematically reviewed. Combined with the actual situation of the health food industry in China， suggestions were put forward for the post-market technical evaluation of health foods in China. There are many useful experiences worth learning from， such as the mandatory reporting responsibility of enterprises in the United States， a special scientific committee which provides long-term technical support in the European Union， post-market monitoring by enterprises in Australia， the establishment of relevant monitoring systems in Taiwan， the relatively mature regulatory system， evaluation system and management system in the field of drugs and medical devices， and the establishment of adverse reaction monitoring bases in the field of cosmetics， the responsibility of post-mark adverse reaction monitoring of food for special medical purposes by medical institutions， and the post-market management in various fields giving priority to safety. In combination with the current situation of China’s health food industry， five specific suggestions， such as promoting the construction of laws and regulations， are put forward.
