It was hoped they would, since the vitamins do reduce levels of homocysteine, an amino acid (氨基酸) that is higher in the blood of people who have a higher risk of heart disease. In fact, homocysteine was reduced 30 per cent after one year of treatment in the participants who took both vitamins. But in the following three years, many vitamin takers died as those who didn't take the vitamins. Even worse, the study was stopped early because another similar study suggested that there may be an increased risk of cancer from taking B vitamins.

I remember sitting in a long meeting with my ankles crossed, when I tried to stand up I crumpled on the floor and hit my chin on the glass coffee table because my legs had gone completely numb and worthless.
