"A US study reports that vitamin and mineral supplements do not reduce the risk of death. And there's a suggestion that high-dose calcium supplements could actually increase the risk.
But the study is hampered by numerous limitations, so the results are not clear-cut.
The researchers looked at data from more than 30,000 adults in the US. This included a one-off 24-hour dietary recall and whether the adults had taken any dietary supplements in the previous 30 days.
This data was linked to a national database to find out who died over the next 6 years.
The main problem is that we do not know if any of them needed to take supplements because of deficiencies.
A large number also reported having had cancer at some point in their life at the beginning of the study, but it's not clear if they still had cancer.
These and other factors reduce any confidence in the results.
This study does not change current advice. Most people who eat a healthy, balanced diet should already be consuming enough vitamins and minerals without having to worry about whether they need to take supplements.
The one exception is vitamin D, which is hard to get sufficient amounts of from your diet in the autumn and winter, as sunlight is needed to stimulate the production of vitamin D.

After reading this research i am afraid of talking supplements.
You should ask to your friends eat healthy food. I also eat healthy food such as whole eggs, salmon, nut, beans, and leafy green.
