科學(xué)家表示，沒有證據(jù)表明這些制劑對健康有益，而且實際上有些制劑還可能損害健康。

一項針對近3.9萬名女性的研究發(fā)現(xiàn)，從統(tǒng)計數(shù)據(jù)來看，多種維生素制劑、B族維生素、葉酸、以及鐵、鎂、銅等礦物元素都會增加過早死亡的風(fēng)險。
Nearly a third of adults in Britain take some form of dietary supplement most days and the industry is worth ￡675million a year.

來自芬蘭、挪威、美國和韓國的科學(xué)家研究了普通維生素和礦物元素制劑的長期健康效果，共有38772名年齡在55歲至69歲的女性接受了調(diào)查。
Over an 18-year period the women recorded any supplements they regularly took.
在調(diào)查的18年中，受訪女性記錄了她們服用的所有補充制劑。
The results, published in the Archives of Internal Medicine, found copper increased the risk of dying prematurely by 18 per cent. Folic acid – which pregnant women are told to take to protect their child against spina bifida – increased risk of death by almost 6 per cent, while iron raised the risk by nearly 4 per cent.

The scientists do not fully understand how supplements may trigger early death, but they may interfere with the body's natural defences. They say the supplements should only be taken by patients who are malnourished and only under the supervision of a doctor. Everyone else should ensure they eat a balanced diet to get adequate vitamins and minerals.
科學(xué)家尚不完全清楚維生素制劑導(dǎo)致過早死亡的原因，但這些制劑會妨礙人體的自然抵抗力�？茖W(xué)家表示，只有那些營養(yǎng)不良的病人才需要服用這種制劑，而且需要醫(yī)生指導(dǎo)。其他人應(yīng)該確保均衡飲食，從食物中獲得足夠的維生素和礦物質(zhì)。
