Shanghai Yangshengtang is the abbreviation of Shanghai Yangshengtang Health Care Co., Ltd.: You can go to the "At Your Service" section of the website of Shanghai Administration for Industry and Commerce to find company information. Located in Pudong New Area, Shanghai, the company is mainly engaged in the sales of health food and cosmetics. The specifications of natural vitamin E soft capsules produced are: 300mg* 160 capsules/bottle, and fruity vitamin C is 500mg* 100 capsules/bottle. Because "Shanghai Yangshengtang" is a place name, not a trademark, there are many fake Shanghai Yangshengtang products on the market now. As far as I know, Yangshengtang adult multivitamin tablets are produced by Hainan Yangshengtang. Shanghai Yangshengtang does not produce multivitamin tablets. If you buy multivitamin tablets from Shanghai Yangshengtang, it must be fake.
