As far as the dosage of the two drugs is concerned, there is no side effect at all (except for pregnant women, who have strict restrictions on the dosage of vitamin E, and the research data show that excessive dosage has teratogenic probability), because the dosage is too low (relatively safe dosage), and we don't know how much vitamin C causes stones, which may be eaten as a meal. These things are health products. As for the efficacy, I dare not compliment. Of course, they have no propaganda effect, but only some psychological effects at most.
