Mike, I meant more the extra vitamin C for the cortisol reduction, not necessarily anything else. Also, the RDA guidelines are... for lack of a better word, made up. Sort of. Those are NOT adjusted for anyone in particular, they are the most general of the general. You should always keep in mind the the guidelines provided by the government are not optimal levels,
they are just made to prevent a deficiency.
Furthermore, there are studies showing that vitamin C doesn't really do anything for your immune system. It does a whole lot of other things, but not so much immune support. Thats straight from the mouth of one of the leading biochemists in the country, so if he tells me its true, then I'm taking his word for it.
I recommended to take the full spectrum amino acids in order to prevent deficiency in any one amino acid, just to clarify.
Finally, I know that vitamin C isn't toxic at doses of upwards of 30grams. I'm not sure where you read 2000mg, but thats definitely wrong. I used to take 3000mg per day. Its NOT recommended to take 4000mg or more per day for an extended period, not because of toxicity but because of the risk of scurvy after discontinuation.

What the second page is saying is that the vit. c gets re-absorbed in the tubules of the kidneys, and so not all of it gets excreted.
