Hello phoenix23002 I personally take at least 10gr of Vitamin C every day on the recommendation of my medical/alternative doctor and also maintenance treatments every six weeks or so of 50gr Intravenous Vitamin C. I also used Avemar (Ave) for many months and will be going back on it soon. My understanding is that Vitamin C will not interfer at all with the Avemar as long as there is at least a two hour window between the two supplements. Here is a link to the Avemar website which is very informative.
