I choose Australia. Australia is a big country of health care products, and the whole people are healthy. R&D and production take a long time, and it has the same international advanced production equipment and technology as American health care products. Compared with the United States, Australia pays more attention to the naturalness of products, attaches great importance to environmental protection, and controls raw materials very strictly. Well-known health care products are certified by international authoritative organizations, and brands such as natural care and healthy care are very good.
