How Much Vitamin C Should I Take ? Dr.Michael Greger
For many years, the RDA (the recommended daily allowance) for vitamins was just based on preventing deficiency with a margin of safety. But, the minuscule amount of vitamin C, for example, needed to avoid scurvy is not necessarily the ideal intake for optimal health. So, what might be the optimal intake of vitamin C? Let’s ask the body. How might we do that? By seeing how much the body absorbs and excretes.
Experiments showing how much vitamin C our body absorbs and excretes can give us a sense of how many vitamin C rich fruits and vegetables we should be take each day.

Nope, you wrong. A human body needs to take 1000 mg of Vitamin C per every 25lbs of body weight , so if a person weights 200lbs, that person needs 4000mg of vitamin C.

200 mg got within range of the optimal levels, 2000 mg got to the higher end, for the second chart greatest benefit was 200mg, it does show a lower risk at 1200 and 1200 absorption rate was 50 percent which is 600mg absorbed not 200, so maybe smaller amounts of c throughout the day would have some improvements. Vitamin c in large doses has been known to cure many diseases so I imagine the absorption rate would change if you were sick.
