Market demand: there is a great demand for health care products, because people pay more and more attention to health, and many people hope to improve their health through health care products. This background of market demand gives some unscrupulous businessmen the opportunity to cheat money.

Health doubts: Many people are very concerned about health problems, but they don't understand the scientific knowledge of physical condition and drugs, which makes some unscrupulous merchants use people's doubts about health and lack of scientific knowledge to defraud consumers' trust through false propaganda and buy health care products.

Marketing means: some unscrupulous merchants often use false propaganda, exaggerate the efficacy of health care products, pretend to have authoritative qualifications and other means to attract consumers to buy. They will cheat consumers with false clinical research results and false expert recommendations.

Lack of supervision: The lack of supervision on the health care products market makes some unscrupulous businesses sell fake and shoddy products through false advertisements, thus defrauding consumers of money. The absence of supervision institutions has increased the living space of these unscrupulous businesses.

In a word, the main reason for the existence of swindlers in the health care products market is the comprehensive effect of market demand, health concern, marketing means and lack of supervision. Therefore, consumers should be rational when purchasing health care products, know the real situation of products, and choose formal channels to avoid being deceived.
