There. Now that I've posted a link, you know it is true. But this information is widely known.
I know nothing of the sort. One study does not convince me of anything.
http://www.ncbi.nlm.nih.gov/pmc/articles/PMC3145266/
I do note, however, some interesting points in the article:
Compared to other genes, the
GLO gene is therefore “predisposed” to being lost because it makes a single compound unnecessary for other pathways.
Explaining the frequent loss of
GLO genes by saying that it only affects the production of a single compound also implies that losing the capacity to make this compound is not selected against, i.e., that such a loss does not cause any selective disadvantage. Since all species which have lost the capacity to synthesize vitamin C have a vitamin C-rich diet, this is the most common explanation brought forward to explain its frequent occurrence...
I did also note some errors in the report, such as the RDA of vitamin C.
I refer you to
http://ajcn.nutrition.org/content/69/6/1086.full
and
http://www.ncbi.nlm.nih.gov/pubmed/14594788?dopt=Abstract
Nevertheless the link you provided said, "...although it has been suggested that a regular diet does not contain enough vitamin C, experiments with guinea pigs did not detect any beneficial effects by increasing the amount of vitamin C in the diet of these animals"
One wonders why we are looking at guinea pigs when studies are available in humans.

And tried to follow some of the links, such as Tomkins 2013b, which apparently refers to Jeffrey Tomkins. Information about him can be found at
http://www.icr.org/jeffrey_tomkins/ so I assume you will reject anything he has to say about the matter after reading, "After receiving his Ph.D., he worked at a genomics institute and became a faculty member in the Department of Genetics and Biochemistry at Clemson. He had become a Christian as an undergraduate at Washington State University in 1982, with a goal to eventually work as a scientist and author in the creation science field. In 2009, Dr. Tomkins joined the Institute for Creation Research as Research Associate," so I won't waste my time looking for his paper.
