　　Vitamins, which maintain and facilitate the body's various functions, are anessential part of our diet. Many people take vitamin supplements to guaranteethem the _(1)_ daily allowance. However, recent studies have suggested that people who take vitamin supplements may be getting too much of a good thing.
　　Many of the foods we eat already have vitamins _(2)_ added to them. People drinking a glass of orange juice may think that they're only getting a dose of vitamin C. In fact, they are also getting added calcium and vitamin D. Breakfastcereal alone provides more than half a person's daily allowance of some vitamins. _(3)_ these levels with supplements can cause some nasty side effects.
　　According to the Office of Dietary Supplements in the US, too much vitamin A can cause headaches and affect bone strength. Too much iron can affect the liverand _(4)_ unpleasant vomiting. Vitamin supplements are not _(5)_ the samerigorous tests as medicine, which makes knowing what's really in themproblematic. Besides, they are not tested for safety or effectiveness because they are not considered a _(6)_ for disease.
　　If you feel that you must take vitamin supplements, nutritionists suggest taking them in _(7)_ doses. This means that if you take a calcium pill, you shouldn't drink too much milk. They also advise against excessive intake, such as eating three energy bars for breakfast and then taking a dose of vitamin A. If your diet is relatively balanced, chances are you are already OK where vitamins are concerned.

服用維他命有撇步
很多人都用錯誤的方式追求健康。
維生素維持且促進身體的各種機能，是飲食中不可或缺的部分。許多人服用維他命補充品，以確保達到每日建議攝取量。然而，近來研究顯示，服用這些補充品的人可能攝取過量的維生素。
我們所吃的食物當中，很多已經含有人工添加的維生素。喝下 1 杯柳橙汁的人可能認為他們只攝取到維生素 C。事實上，他們也獲得額外添加的鈣質和維生素 D。光是早餐吃的穀類食品就提供某些維生素一半以上的每人每日攝取量。因此，服用補充品增加攝取量可能造成一些嚴重的副作用。
根據美國膳食補充品辦公處的說法，過量的維生素 A 可能引發頭痛並影響骨骼強度。過量的鐵質則可能影響肝臟和導致令人難受的嘔吐。維他命補充品不同於藥品，不會接受相同嚴格測試的管制，這讓了解維他命的真實成分顯得困難重重。由於它們不被視為疾病的治療方法，所以也不會經過安全和效用的檢測。
倘若你覺得一定要吃維他命補充品，營養學家建議攝取合理的劑量。這表示假如吃了 1 粒鈣片，就不要喝太多牛奶。他們也建議不要過量攝取，像是吃了 3 條能量棒當早餐後，再吃 1 劑維生素 A。如果你的飲食相當均衡，可能就不用擔心維生素攝取的問題了。
