Generally accepted with some debate
"Vitamin C is a well-established essential nutrient with clear benefits for immune function and antioxidant protection. High doses are often used to shorten the duration of colds, although the evidence is mixed. It's most effective when taken preventatively or at the very first sign of symptoms. Absorption can be a limiting factor at higher doses."
