Why can't "Riyuexing Protein Powder" be found in official website Health Food of State Administration of Pharmaceutical Products? This brand seems to be very popular, and there are many entries on the Internet. Others say that the country is famous. The common problem of health food is blind registration of trademarks, so the product name called during publicity is often inconsistent with the approval; Moreover, the product is approved by the national department, and the provinces have no right to approve it, so you can only tell me the product approval number, so as to help you check with the US Food and Drug Administration. It's actually quite simple. Look at the top left corner of the largest packaging surface of the product. The approved health food should have a police mobile force, with "health food" and the approval number written below. Enter the document number in the data query under the state/US Food and Drug Administration. If it has been approved, it should be ready for use. Alas, I wrote so much.
