Our Go-To Vitamin C

Posted by Reviewer1640906 on Dec 07, 2016

For years now I take 1 to 2 every day as part of my vitamin regime, but in times when I feel the early signs of a cold, I ramp that up to one every hour or so until there are no symptoms. This can mean 5-10 a day. As Linus Pauling discovered there is a cure to the common cold. I find this the easiest form of Vit C to take large quantities of.

Well tolerated

Posted by 5608900336638002819 on Dec 02, 2016

I am actively working to improve my immune system and Vitamin C is key in that effort. This formula is well-tolerated and seems to be truly sustained release as there does not seem to be signs of it being eliminated from the body in large amounts. Sorry if that is TMI, but there isn't really any other way to tell that I know. So far have been feeling better overall.
