Jin Shierkang is the vitamin brand of Sino-American Squibb Pharmaceutical Co., Ltd., which occupies a major position in Squibb OTC business, with high market share and stable sales, and was once known as the three major brands of vitamins in China together with Shancun and 21 Gold Vita.
 
Sino-US Squibb is a joint venture between the well-known pharmaceutical company BMS and the Chinese side, with strong production strength, in addition to vitamin products, prescription oncology drugs, etc. Jin Shierkang series vitamins belong to OTC class B drugs, and the product classification is not as detailed as that of Shancun and other brands, and there are only two types of Jinshierkang adult and small Shierkang children.
 
As a pharmaceutical vitamin, there is little difference between the content of Jinshierkang and Shancun OTC multi-dimensional element tablets, and its vitamin A content is higher than that of Shancun, reaching 5000IU/capsule, and the vitamin content of each capsule has reached the recommended daily value or above. Xiao Shierkang is a chewable tablet type, with added food flavors and sweeteners, which is beneficial for children. Compared with Jin Shierkang, Xiao Shierkang has the same amount of vitamin A, no minerals, only vitamins, because children are relatively sensitive to vitamin A, it is not recommended for children with normal nutrition, and parents must consult a doctor when taking it to their children.
 
Some people will have symptoms of gastrointestinal discomfort when taking Jinshierkang, and other brands of vitamins will also have a similar situation, the main reason is that some minerals in multivitamin tablets will irritate the stomach, most vitamin tablets use calcium carbonate as a calcium raw material, which is cheap but irritating to take on an empty stomach, so it is recommended to take it after meals.
