This company make their own supplements under the name of California Gold Nutrition. I ordered a C0Q10 but when it arrived I noticed it contained modified food starch. I wrote to customer service to enquire what it was made from and if it was GMO. I have had 6 messages back from someone sounding like they are screaming at me and asking me why I am asking this and where do I get my information. I keep writing back saying I am not accusing them of anything but asking. Finally she answered saying it is corn starch so I wrote back asking where they purchase it if it is not GMO, all I got back was another email 'screaming' at me again asking me where I get my information. This company seriously has something going on and say on their home page, that they don't use GMO wherever possible. As corn in the US is 90% GMO I have to assume this product contains GMO and I am throwing it away. They are unbelievably impossible to speak to and very rude.
