According to him, there is no scientific evidence that vitamin C in large doses reduces the duration of the disease and the severity of the coronavirus disease.
“Taking more than the safe dose of a vitamin can lead to side effects.

Also, the use of high doses of vitamin C for a long time contributes to the more rapid formation of kidney stones, which is important to know for people who are predisposed to this disease.
When taking vitamin C along with iron, excessive accumulation of iron in the body is also possible, ”said Lomonosov.
