I noticed that several people have talked about megadosing their vitamin C, and I was wondering why? I know the loss of the ability to synthesize vitamin C has been put forward as a reason to megadose, but I'm not sure I understand that as a reason to consume more.
Here is my current knowledge of Vitamin C, based on conventional nutrition:
-Your ability to absorb vitamin C decreases as the dose increases. Ex. 1 g, you absorb 75%; 3 g, you absorb 40%; 5 g, you absorb 25%.
-Vitamin C at very high doses interacts with iron, creating oxidative stress
-A possible "rebound" deficiency occurs when supplementation is stopped because of decreased absorption
The reduced absorption I assume is the reason why people say that taking lots of vitamin C makes for pricey urine.
Has anyone experience health improvement from taking loads of vitamin C? Does anyone have any studies or articles they can direct me towards? I haven't really looked into this, but I thought one of you probably has and could give me a hand!
