Common questions
The standard is 90 mg for adult men and 75 mg for adult women. Smokers need more, an additional 35 mg/day, and the numbers go up during pregnancy (85 mg) and while nursing (120 mg).
There's an upper limit of 2,000 mg a day for adults. Vitamin C is water-soluble, so your body clears out what it doesn't use, but going well over that limit regularly can cause digestive upset.
The evidence suggests it can modestly reduce how severe a cold is and shorten how long it lasts. It's not going to prevent you from catching one, but it may make the experience shorter and milder.
It's a genuine multi-tasker. It supports collagen formation and wound healing, helps your body absorb iron, supports adrenal gland function, and acts as an antioxidant throughout the body.
