While vitamin C supports immunity and overall health, most people can meet their needs through a balanced diet without risking unnecessary side effects. Read along with the original article(s) here: https://www.healthline.com/nutrition/side-effects-of-too-much-vitamin-c Quotes to ponder: "Consuming too much vitamin C has the potential to increase the amount of oxalate in your urine, thus increasing the risk of developing kidney stones." "It’s nearly impossible to consume too much vitamin C from food." "Unless you have a vitamin C deficiency, which rarely occurs in healthy people, it is probably unnecessary for you to take large doses of this vitamin."
