Health foods fall under the category of foodstuffs, and do not need to undergo strict testing before they are sold. Nevertheless, they are often produced in capsule or tablet form, and appear to be no different from medicine. Manufacturers also frequently insinuate that they possess powers to treat various kinds of ailments.
健康食品屬於食品類，不須經過嚴格檢驗即可上市；但它們常被製成膠囊或錠狀，看起來跟藥沒有兩樣，業者也常會暗示他們具有某些療效，這就形成管理上的灰色地帶。
