Health food is not allowed without anti-counterfeiting query code. When you don't check whether the health care products business is genuine, you should first look at whether there is a small blue hat on the package. As long as it is a real health care product, the Ministry of Health will use the police mobile unit as a special symbol, and indicate the product approval number, manufacturer's name, production date and expiration date in the eye-catching position of the outer packaging box. The regular batch number is generally under the little blue hat. The market is full of fake health products. If you don't observe carefully, there is no certain method, and it is easy to be deceived. Many people are cheated when they buy health care products and medicines. They not only wasted a lot of money, but also seriously affected their health. So be careful.
