Did you know that the Recommended Dietary Allowance (RDA) for adult male smokers is 35 mg/day higher than for non-smokers? This highlights why a single, simple RDA formula for vitamin C does not exist, as requirements depend on a range of factors including age, sex, and lifestyle.

Taking amounts higher than this can lead to potential side effects or risks associated with excessive vitamin C intake. This guide details what happens when you consume too much and provides the official dietary guidelines for various populations.
