Drugs refer to substances used to prevent, treat and diagnose human diseases, purposefully regulate human physiological functions, and specify indications or functional indications, usage and dosage. Health food is used to regulate the body's function, improve the body's disease resistance, improve the sub-health state and reduce the risk of illness, not to prevent and treat diseases. Simply put, drugs can cure diseases, but health care products can't. Let's take a concrete look at their differences: the production capacity and technical conditions of different drugs in production and formula must be strictly examined by relevant state departments, and they must be strictly examined in pharmacology, pathology and virus, and after years of clinical observation, the curative effect and indications are clear, and the adverse reactions are clear before they can be put into the market; Health products can be put into the market without hospital clinical experiments. Quality control in the production process Different vitamin drugs must be produced in pharmaceutical factories, and the quality control requirements in the production process are very high, such as air cleanliness, aseptic standards and raw material quality. At present, all drugs must meet GMP standards. Vitamin food can be produced in food factories, and the standard is lower than that of pharmaceutical production. "Wei Shi Jian Zi" or "Shi Guo Jian Zi" with different approval numbers and signs are the approval numbers of health food products approved by the Ministry of Health and the State Food and Drug Administration in different periods, and "Wei Shi Jian Zi" is the approval number of the Ministry of Health in 2003 and before. Since the establishment of the US Food and Drug Administration in 2004, the word "Weishi" had to be re-approved and changed to "Shiguo". Drug quasi-word: it is a drug, which can cure diseases and has curative effect; Food health care words: health care products, can protect health, can not cure diseases. As a drug with poor curative effect, it must undergo a lot of clinical verification and be approved by National Medical Products Administration (SFDA). It has strict indications and has a certain curative effect in treating diseases. As a health food, it has no therapeutic effect, and it can only be marketed by detecting health indicators such as pollutants and bacteria.
