How about the FDA certification?
The U.S. FDA (Food and Drug Administration) is an agency of the U.S. federal government that regulates the safety of food and drugs. The FDA has strict standards and procedures for regulating gold-containing products, especially food and drugs that may contain gold.
In the U.S., many foods and pharmaceuticals contain small amounts of metals that may be used to add value to a product or to serve a specific purpose. However, if the metal content is too high, it can be harmful to human health.
The FDA sets standards and limits for gold-containing products based on scientific research and expert opinion. In general, the FDA requires manufacturers to clearly indicate the gold content on product labels and ensure that the metal content is within safe limits. In addition, the FDA regularly conducts random inspections of products on the market to ensure compliance.
For gold-containing foods, the FDA usually imposes strict controls on metal content to ensure that it does not pose a health risk to consumers. For example, for gold-containing beverages, FDA requires manufacturers to add maximum metal content limits to their formulas and to monitor and inspect the manufacturing process.
As for gold-containing drugs, the FDA strictly requires pharmaceutical companies to provide sufficient safety and efficacy data to ensure that metallic ingredients will not affect the efficacy and safety of the drugs. All drugs must be approved by the FDA before marketing to ensure compliance with relevant regulations and standards.
Overall, the U.S. FDA has stringent regulatory standards and procedures for gold-containing products that are designed to protect the health and safety of consumers. When purchasing gold-containing products, consumers should pay attention to the gold content information on the product label and choose reliable brands and products to ensure that their health is not compromised.
