to also take copper as vit c depletes copper in your body? For some reason this Vit c I had a lot of problem with. It made me feel irritable and gave me an acid stomach. I prefer Vit c from life extension as it doesn't have the side effects of this one

Far too low PH

Posted by 5132604943336530110 on Sep 01, 2013

This product may be easily absorbed, but it is a disaster for your stomac. I tested the PH was as low as it could bee on the test strip. It is sad that the traditional buffered C-vitamins, pure calcium ascorbate, hardly seems to be manufactured any more. I quite sure that I am not the only one with a sensitive stomach.
