question: Hello doctor, I am 21 years old female. I want to use Glutathione for skin whitening. So I want to know whether 1000 mg Glutathione is safe for the body or not? Will taking 1000 mg Glutathione daily show any side effects? If yes, then what type of side effects it will be? Will it affect my menstruation? Well, my health is good. Sometimes, my heart feels uneasy and my knee aches a bit but apart from that I am fit.
