Vitamin C
Vitamin C yog cov dej-soluble vitamin tshaj plaws. Nws yog feem ntau koom nrog hauv kev tsim cov tshuaj tiv thaiv kab mob collagen hauv lub cev, cov nyhuv redox ntawm cov ntaub so ntswg kho, rog thiab protein synthesis, thiab tswj qee yam haujlwm ntawm lub cev. Kev kho mob tseem ceeb ntawm cov vitamin C yog cuam tshuam nrog scurvy tshwm sim los ntawm vitamin C tsis txaus, tau kawg, nws tseem tuaj yeem siv los ua cov tshuaj ntxiv rau ntau yam kab mob sib kis thiab mob ntev thiab purpura.
