Re: Vitmain C synthetic vs. natural

I think any brand of vitamin C that is non Genetically-Modified-Organisms corn is fine. The label usually says non-GMO or no GMOs = (Genetically Modified Organism(s)). Mexican corn believe it or not is the best and is non Genetically-Modified-Organisms by in large. The farmers stood up to protect their corn industry from Genetically-Modified-Organisms contamination but only for corn. Not other foods. They have 100's of types of corn in Mexico and is part of their cultural identity. Apparently, Mexicans can by American GMO corn seeds cheaper (due to the large government subsidies on these) than the Mexican organic seeds but most of the farmers refuse to do so. I think they are a hell of a lot smarter than farmers here in this respect.

There is a number of very large companies that have a policy to use non GMO plants for all their vitamins/supplements and have their own farms. It won't be hard for you to find which these are. If I were you I'd go to a number of small family owned supplement stores. They frequently buy these brands and can tell you what you are asking me in detail.
