Despite the abundance of rumors and anecdotal evidence, ultimately nutritional supplements have not undergone the same stringent clinical testing as pharmaceutical products, and thus there is no guarantee as to their effectiveness to alleviate symptoms. It's still necessary to see the doctor when ill, and believing in a product's efficacy is not sufficient reason to postpone seeking medical advice. Most people today do not enjoy perfect health.
儘管有許多言之鑿鑿的見證或傳說，保健食品終究不是經過嚴格把關、通過層層臨床實驗的藥品，也不保證能有效的改善體質、緩和症狀，生病的人還是得看醫生，不能因相信食品的功效而延誤就醫。
