Where does Yi Kexin come from?

Yikexin, a vitamin AD drop, is produced by Shandong Dyne Marine Biopharmaceutical Co., Ltd., and Yikexin is the trade name given to the drug by the company. Other pharmaceutical companies or factories may also produce this drug, but it will not be named Yikexin. This is a trademark right. There are many vitamin AD drops produced by manufacturers on the market now. The so-called "fake drugs" can be taken seriously, and the quality of fake drugs cannot be guaranteed. It is recommended to distinguish carefully.
