(The above question refers to the traditional acidic vitamin C. If it was acid-free vitamin C, such a thing would not have happened. )
Recently, Austrian scientists have warned that the abuse of vitamin C will weaken human immunity.
Professor Goldberg of the Institute of Medicinal Chemistry of the University of Vienna recently told the press that studies have proved that vitamin C plays an important role in the composition of neurotransmitters such as protein and adrenaline in human connective tissue. When people are infected or have other inflammations, the demand for vitamin C also increases, but we must be very cautious when using large doses of vitamins.
Professor Goldberg warned that increasing the dose of vitamins to more than once a day is not only meaningless, but also likely to backfire. Because there is too much vitamin C around white blood cells, it can not only prevent white blood cells from destroying germs, but also protect germs and cancer cells. Excessive vitamin C can not only enhance human immunity, but also weaken it. Professor Goldberg specially reminded us not to take vitamin C casually like eating jelly beans.
But if you eat more vegetables and fruits rich in vitamins, such as oranges, peppers, tomatoes or potatoes, you don't have to worry about taking too much vitamin C.
At the same time, American researchers have found that the abuse of vitamin C may accelerate arteriosclerosis.
