But even if vitamins have many important jobs and not getting enough can be dangerous, you also have to be careful not to slip to the other side, says Dragsted. ‘Vitamins are very bioactive substances,’ he explains.
This means that they play an important role in the body’s chemical processes. And in large quantities, some vitamins can be harmful.
One vitamin pill usually contains one or two times the recommended daily allowance, and some vitamins are already harmful from three or four tablets. This applies, for example, to vitamin A which is soluble in fat.
The water-soluble vitamins rarely reach harmful levels, but B3, B6 and C can cause itching, numbness and diarrhea at high doses.
The future of vitamin pills is personal
In the future, taking our daily vitamin pill could be a personal matter, with the vitamin content tailored to our individual needs.
Our genes determine how well cells can absorb certain vitamins, how efficiently they are converted from inactive provitamins to active vitamins, or how well they working in the machinery of the body.
