B vitamins affect DNA synthesis, growth and repair of our cells. It is clear that this is very suspicious in terms of the development of malignant tumors.
At some point, something similar was even detected in scientific research. We followed a large number of people and noticed an increased risk of developing cancer.
Then the scientists came to their senses and realized that such observations are not very reliable. You can find a connection in them, but the reason is harder to understand. It would be necessary to plan special complex scientific studies from scratch with cunning statistical analysis.
Fortunately, there was a lot of complex scientific research in the field of cardiology. There they watched people who took vitamins and expected heart attacks. But some of these people did not die of a heart attack, but of cancer.
Usually it was about a variety of supplements with vitamins B6, B9 and B12.
And so scientists have collected about twenty of the most juicy and high-quality studies, in which something about 80 thousand people have accumulated. The whole thing was shorthand, and it turned out that supplementation with B vitamins did not affect the risk of developing cancer, nor the death rate from cancer, nor the overall mortality among these people.
On the other hand, it became clear that if someone is abusing vitamins in large doses, then he theoretically can provoke the growth of microscopic tumors that will appear sometime in the future, and this will still be very monitored for a long time.
But as a pleasant bonus, they found out that B vitamins reduce the risk of developing melanoma. Everything turned out to be better than expected.
And you do not abuse vitamins?
