Only Vitamin C + menadione product on the market

Posted by Reviewer2733085 on Dec 08, 2011

This looks like a very promising combination for various forms of cancer, however the fact that the vitamin C is in the form of ascorbic acid limits the amount that many will be able to tolerate. A buffered form of vitamin C would be better.
