Is 1000mg vitamin C a lot?

DailyRequirement60mg. 1000 mgm is a lot.Daily requirement of Vitamin C is 60mgm.You can get enough from your diet if you have citrus fruits/juices,tomato,papaya,green leafy vegetables like kale,kivi fruit,bell peppers,guava,brocolli,strawberriespeas.Some recommend supplement up to 1000 mgm but I don't exceed more than 500 mgm as large doses can cause diarrhea,nausea,abdominal pain,Calcium oxalate kidney stones etc.
Controversial! I believe 300mg per day is enough. Some physicians believe that 1000mg/day is ok. I disagree!
