Vitamins can be beneficial and can be harmful
Experts at Brigham Women's Hospital in the United States said that vitamins themselves could be beneficial or harmful because their effectiveness was linked to individual characteristics, including genetic ones.
"The work of vitamins is determined by genetic differences, for example, the same vitamins may be useful and may be dangerous," say the authors of the new theory on the effectiveness of vitamin supplements.
Scientists have decided to determine the real benefit of taking whole vitamins or individual vitamins and have focused their selection on the "vitamin" for which various studies have identified an effect on the body.
But the results obtained by the scientists in this study were heterogeneous. The results of some experiments have shown the protective effect of this vitamin, but tests using vitamin "" placebo have not confirmed its positive effect.
Researchers believe that the effect of vitamin-containing supplements is linked to the patient's genetic makeup.There is a methyltransferase gene (COMT) that determines whether vitamin E can protect against the development of cancer or, conversely, increase it. "
The researchers found that in women taking vitamin E, the risk of cancer depended on any COMT option in their body. Met Met, who had good cancer protection, was 14% less likely to benefit from the Val / Val option, where vitamin supplements increased their risk of infection by 15%.
Based on these results, scientists plan to determine which cancers can be caused by vitamin E in people with the Val / Val gene.
