C-vitamiini leidub taimse päritoluga toiduainetes. Parimad Eestimaal kasvavad taimed, mis rohkelt askorbiinhapet sisaldavad, on must sõstar, kibuvits, lehtkapsas, hapukirss, mädarõigas, petersell ja astelpaju. Võõramaistest tulnukatest on rohkesti C-vitamiini paprikas, kiivis, papaias ja tsitrusviljades.
Vitamin C is essential for the synthesis of collagen, a protein important in the formation of connective tissue and in wound healing. It acts as an antioxidant, protecting against damage by reactive molecules called free radicals. The vitamin also helps in stimulating the immune system. It has been shown in animal trials that vitamin C has some anticarcinogenic activity.
