I checked the actual container I bought (I had already thrown the box away) and it only lists that it contains 20% L-Ascorbic acid. It doesn't list anything other ingredient so I went on the US Patent & Trademark website to do a search for the product since it states on the back of the container that "this patented Vitamin C formulation......" but couldn't find anything but then that may have been that I wasn't searching the website properly as I am not familiar with the US Patent office. If my product had a patent I would definitely list the patent# directly on my product but this container doesn't show any patent number.

I use their vitamin c hydrating toner and have been really happy with it. It is also a great product.

This product sold by Swanson Health Products is sold at a lower price than some of the other competitors and sellers on Amazon. If another supplier chooses to sell this product at a higher price, we have no control over the amount they sell it for. We hope this helps clarify. -Swanson Health Products

Where the ingredients are listed on the jar, the word Ascorbyl Palmitate (Ester C) is listed as the 10th ingredient. The word aborbic acid or L-ascorbic acid is not listed. But I will say this works great with the retin A I use at night. I will be purchasing this again.

I called Swanson, to find out the source of the ascorbic acid they use in making their Vitamin C powder. The answer was that it is "derived from sugar alcohols, made from corn". So, yes it is corn-derived. Susan Calderone October 7, 2013

The information on the label was designed to comply with FDA requirement for such product. Moreover this product typically retains its effectiveness upto two years when stored well. Mostly, they are used up within few weeks to months of production, so as important as expiry date is they may not be an issue with so many vitamin c serums.

You are asking others who bought the product, not the company who sells it. I do not think so, but try Ebay

All of our stock is freshly manufactured in the USA. We purposely order in small quantities so that the stock does not age while it is in the Amazon warehouse waiting to be purchased. The shelf life is 3 years and once you open the bottle the potency of the vitamin C will last for up to 12 months.

As far as I know, the only ingredient is human grade vitamin C. I would contact the company just to make sure if you have any other questions or concerns.

When it comes to healthiness of Vitamin C, what matters is purity: whether it is made in the USA and the reputation of the manufacturer. Foreign-made chemicals can have ANYTHING in them, scary. GMO-free is irrelevant when you're talking about a pure chemical derived from a food source. Corn could have petunia genes or buffalo genes or whatever, but the resulting ascorbic acid is just a simple chemical with no leftover genetic material.

Hi wmi,Our supplier is the only European manufacturer of vitamin C in the world and confirms that our vitamin C is free from GMOs with every batch. Having an agreement set in place with Non-GMO Project would significantly increase our costs, and it's important for us to maintain our competitive pricing for our valued customers. This is why we state that our vitamin C is non-GMO, but cannot place the logo on our label without an official third party certifier.

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

The only certification mentioned on the label is that of " Quality Assurance International ". This would be relevant to the organic integrity of the contents. Regardless of the certification one way or another we would recommend this product and have been using it for several years now for both men and women. A difference in health was noticed when we had temporarily run out! (as for complete Vitamin C ... easy and cheap to obtain as an additional supplement, which we normally do anyway)

The bottle does not specify, but one review states that it called the company and questioned someone on each ingredient. They claim cyanocobalamin.

This product uses "Sodium Ascorbyl Phosphate" (Vitamin C). It is listed just like this, but without the quote marks.
