Nutritionist Elena Sukhanova spoke about the features of B vitamins, as well as why you should not be afraid of their overdose.
/b> One of the main features of all B vitamins is their water solubility. And this means that they are perfectly excreted by the body, which will leave itself exactly as much as it needs.
“Therefore, overdoses are extremely rare. And all the B vitamins are enzyme vitamins, that is, they are players that accelerate all the processes in which they participate, ”the expert notes.
Despite the fact that each of the B-vitamins is more responsible for a particular process in the body, they also have common functions and properties. For example, it is these nutrients that are responsible for the synthesis of energy from food.
It is also worth considering that in order to get the greatest effect from taking these vitamins, you need to take them in combination, and not separately. It is in this form that they exist in nature.
If someone tells you that vitamin B12 is poorly absorbed from B1, B9 and B3, then this applies only to large therapeutic doses. Moderate preventive dosages of these vitamins do not contradict each other.
For better absorption, give preference to natural rather than synthetic vitamins.
