I bought several bottles of vitamin E from Taobao some time ago. When inquiring, I found that Yangshengtang is divided into Shanghai and Hainan, and the prices are quite different. Hainan has a minimum of 53 bottles and Shanghai has a minimum of 16 bottles. Hainan's main raw materials: natural vitamin E, safflower seed oil and perilla oil, while Shanghai's main raw materials are natural vitamin E, soybean salad oil and gelatin. And the most important thing is that the functional content is different. Shanghai is only half of Hainan. There are real manufacturers in Hainan, but Shanghai Yangshengtang is not produced in Shanghai. We consumers don't know what company Shouguang was commissioned to produce. There is another one. Shanghai Yangshengtang can't find one of his counters, and there is no way to verify it. I suggest you stop using Shanghai. If you bought it through formal channels, you can return it to their home, because even the labels in Shanghai are fake.
