According to her, excessive consumption of vitamin A can lead to oncology. “It is an antioxidant and protects against oncology, but its overdose can, on the contrary, lead to oncology. In fact, in general, this applies to any vitamins, because one way or another, everyone can harm in their own way, “the specialist explained.
The expert noted that an overdose of vitamin C can lead to allergic reactions, and in the case of constant intake – to the possibility of the formation of kidney stones.
