Recent BBC news indicated two controversial topics.
One is that Iron tablet is useful for women anemia,
Iron pills may help women beat fatigue
Prescribing iron supplements may help some women with fatigue even if they are not officially anaemic, Swiss researchers suggest.A severe shortage of iron is the most common cause of anaemia resulting in lethargy, weakness and feeling faint.
A study of 198 women, published in the Canadian Medical Association Journal, showed iron pills may also help those with moderately low iron levels too.
Taking too much iron, however, can be dangerous.
The researchers looked at reproductive age women, between 18 and 53, as menstruation is known to lower iron levels.
They said unexplained fatigue was a common problem in doctors' surgeries, but it was as yet unknown whether iron supplements could help these women.

another is that Calcium tablet might increase the risk of heart failure.
Calcium pills pose 'heart risk'
People who take calcium supplements could be increasing their risk of having a heart attack, according to researchers in Germany.Calcium is often taken by older people to strengthen bones and prevent fractures.
But the study, published in the journal Heart, said the supplements "should be taken with caution".
Experts say promoting a balanced diet including calcium would be a better strategy.
The researchers at the German Cancer Research Centre, in Heidelberg, followed 23,980 people for more than a decade.
They compared the number of heart attacks in people who were taking calcium supplements with those who did not.

This news was tweeted before.
Actually, supplements are easy to take the ingredients and we can save the time to think about the balance of diets.
However, I strongly believe that our health is basically based on eating and exercise. As long as we don't have a strong reason I can't manage it, we shouldn't expect the supplements too much.
