where is this vitamin c coming from and I've read it comes from corn grown in China? What guidelines of quality do the farmers practice?*

Check your facts! Where did you read it's made from corn grown in China? I called the company--nothing comes from China in their products.

Nothing on the bottle says anything about the sources. I would look at they website, it details manufacturing, standards, etc. They strive for non-GMO and have strict standards and an open plant to physicians. You could give them a call to confirm that products are not sourced from China. Hope this helps.

I could not find any words on the bottle saying where it was manufactured. I only see a "Distributed Exclusivley by Jarrow Formulas..."The manufacturing location may have been on a box that the jar of vitamins came in but I am not sure if it did come in a box and where that might be. I'm sorry I couldn't be of more assistance!

Most manufacturers will NOT divulge that information. Please contact Bulk Supplements directly to see what they say. "Vitamin C" is manufactured almost solely in China via an industrial process that's purely synthetic or via microbial fermentation, so for the fermentation process there would definitely be GMO components, because the microbes (algae or bacteria) are genetically engineered. Here's a paper on how most vitamin supplements are produced today: Ascorbic acid production. From: Vandamme EJ. Production of vitamins, coenzymes and related biochemicals by biotechnological processes. J Chem Tech Biotechnol 1992; 53:313-327. Most manufacturers will NOT divulge that information.

The manufacturer is closed until Monday, so we would have to follow up with you at that time. The manufacturer is emphatic that it is non-GMO, so they are either using organic corn, or certified non-GMO corn. But in any event, we will inquire from the manufacturer on Monday (they are on the West coast) and get back to you. Thanks. UPDATE: After talking to the manufacturer, we have confirmed that all of the corn that is used in the manufacturing of the Ascorbic Acid is certified GMO-free, although by the time they complete the manufacturing process, there is absolutely no corn residue left at all. We hope this helps.

I really do not know. The packaging does not say, nor does it provide the source of the ascorbic acid. However, it seams fresh. I recommended it to a friend.

GMO! I bought it thinking it was not. I will be returning it. Google GMO free vitamin C. There's one made in England.

I love metagenics so this is hard to say---it probably has GMO. Anything made with ascorbic acid is coming from corn and that probably has a high percentage of being GMO. Forget the gluten problem GMO is just not healthy for everyone including people sensitive to gluten.

I tried to find out the answer to those questions myself. I wasn't positive if I got my answer. On the box it says Manufactured exclusively "for" Salvere Health located in Oregon. But that wasn't the answer I was hoping for. I like when it says made in USA plan and simple. Also it just says Vitamin C, not L-Ascorbic Acid which is the form of Vitamin C that is less irritating and been shown to have good results. But in spite of the lack of clarity, I tried it because of its high rating. I seem to be trying a lot of these serums of this type, I had the best results with Salvere .

There is NOTHING on my bottle that says "Made in China." I've purchased this outside of Amazon and have NEVER seen that on the bottle. Why not call their company 1-800-421-9210 and ask. Maybe your bottle was made in China? I really don't know how to answer your question. All I will say is this Vitamin C Powder is *VERY* good! I will always take it!

Hi Mr R., It is in the form of L-ascorbic acid which is naturally occurring in food sources, unlike D-ascorbic acid which must be chemically synthesized. Hope this helps answer your question, and if you have any other questions you can reach us by responding to this comment thread or by email at amazon@vivalabs.com.

I just spoke with Tom at Life Extension. He didn't say corn derived. He said it was synthetically derived. I tried a "natto" derived supplement and experienced terrible stomach upset. Even though it's synthetically derived, I consider it the lesser of two evils.

I looked the item up on Amazon. The page you bought it from says, "Made in the USA". It makes sense to me because we grow so much corn here at home. I hope that allays your worries. Mark

I am not sure Larry. I do not use it anymore. I was always under the impression that Vitamin C had to be taken orally or eat an orange for it to do any good. It did feel great on my skin however. Maybe go to the makers web site to see just how much vitamin c is actually in it.

REAL vitamin C from organic fruits can be found in the Alive brand of powdered vitamin C. The ascorbic acid vitamin C in these and other capsules and pills is made from genetically modified corn.

I'm not sure what it is made from, but according bulk supplements' website it is non-gmo. I prefer this too. :) http://www.bulksupplements.com/ascorbic-acid-vitamin-c-crystalized-powder.html
