研究發現 維生素補充劑幾乎沒有什麼積極作用

People who use vitamin and mineral supplements to keep their heart in tiptop shape probably aren't getting much out of it, suggests a new review published in the Journal of the American College of Cardiology.

一項發表在《美國心臟病學會雜誌》上的最新評論指出，使用維生素和礦物質補充劑來保持心臟處於最佳狀態的人，可能並沒有獲得太多的幫助。

The study found that most popular supplements, such as vitamin C and calcium, seemed to provide no benefits in preventing cardiovascular disease or early death. Some even appeared to slightly raise the risk of death.

研究發現，大多數受歡迎的補充劑，如維生素C和鈣，似乎對預防心血管疾病或過早死亡沒有任何益處，反而似乎會稍微增加死亡的風險。

Researchers analyzed more than 150 randomized clinical trials published from 2012 to 2017. In total, they looked at trials of 15 vitamin and mineral supplements, including multivitamins.

研究人員分析了從2012年到2017年發表的超過150個隨機臨牀試驗。總的來說，他們研究了15種維生素和礦物質補充劑的試驗，包括複合維生素。

The four most commonly used supplements in the US -- vitamins C and D, calcium, and multivitamins in general -- were found to have no significant effects on any cardiovascular health outcomes, or on the chances of dying prematurely.

研究發現，美國最常用的四種營養藥--維生素C、D、鈣和複合維生素，對心血管健康的任何結果都沒有顯著影響，也沒有對過早死亡的可能性有顯著影響。

Across 43 studies, for instance, there were 2,908 deaths among 18,719 people who took vitamin D, compared to 2,968 deaths among 18,831 people in control groups.

在43項研究中，18719名服用維生素D的患者中有2908人死亡，而對照組的18831人中有2968人死亡。

"We were surprised to find so few positive effects of the most common supplements that people consume," said lead author David Jenkins, a professor in the department of Nutritional Sciences at the University of Toronto in Canada, in a statement.

加拿大多倫多大學營養科學系的教授大衛·詹金斯在一份聲明中表示：“我們驚奇地發現，人們攝入的最常見的補品幾乎沒有什麼積極作用。”

"Our review found that if you want to use multivitamins, vitamin D, calcium or vitamin C, it does no harm—but there is no apparent advantage either."

“我們的研究發現，如果你想使用多種維生素、維生素D、鈣或維生素C，雖然不會對身體造成傷害，但也沒有明顯的優勢。”
