Vitamins, pros and cons
Most people assume that vitamins, even in large doses are not harmful because they are natural and in fact there were no signs of side effects during the execution of various scientific studies.
The participants were asked the same three months about side effects, but nothing serious was reported and there was no difference between those who received placebo and those receiving vitamins.
But some experts say they are against, that everyone take very high doses of vitamins, due to possible risk of cancer associated with folic acid and other unknown side effects.
But the risk of cancer is small and is connected to taking folic acid in large quantities, research suggests that even in this case only affects the smokers and people with certain genes associated with the processing of the vitamin.
