Turns out too much of a good thing is not really good

Several people swallow pills, meaning vitamin pills, regularly. The collection is usually a combination of A, B, C, D, E, plus calcium, B Complex, B12, you name it.

Haven't heard much about all vitamins, but vitamin E supposedly causes more harm than good. Other vitamins also fail in producing any benefits to our health.

Here's what I read about effect of vitamins in general. 'A January 2009 editorial in The Journal of the National Cancer Institute noted that most studies of vitamins had shown no cancer benefits, but some had shown unexpected harms. Two studies of beta carotene found higher lung cancer rates, and another study suggested a higher risk of precancerous polyps among users of folic acid compared with those in a placebo group.

In 2007, The Journal of the American Medical Association reviewed mortality rates in randomized trials of antioxidant supplements. In 47 trials involving 181,000 participants, the rate of dying was 5 percent higher among the antioxidant users. The main culprits were vitamin A, beta carotene and vitamin E; vitamin C and selenium seemed to have no meaningful effect.'
