"Alternative medicine" is double-speak. If it is not medicine, then it cannot be called medicine. I am changing "alternative medicine" to "alternatives to medicine" to emphasize that "orthomedicine" is not medicine. An encyclopedia is not a forum for pseudoscientists to use double-speak to make their quackery sound legitimate.
Pseudoscience
The evolutionary claims advanced by Mathhias Rath have no bearing in science whatsoever. Giving him an entire paragraph in this article lends him undue respectability.Can you imagine an article on the element mercury say, with a paragraph about the controversial doctor-x who theories that evolutionary deficiencies of it result in tennis elbow or some such nonsense. This article is replete with dubious nutrition as it is,without adding spurious evolutionary theories into the mix.Im removing the mathias paragraph for this reason.If people want to read about his crack pot theories they can look him up in his main article.

C Vitamin
Another indication (proof) of the myopia, insolence, and arrogance of the contributors from the Land of Intelligent Design: not only is this article incorrectly called 'Vitamin C' instead of 'C Vitamin' but THERE IS NO REDIRECT from 'C Vitamin' either. It's time people with this lack of savvy retired from Wiki.
About the opening sentence
The article begins with: "Vitamin C ... is an essential nutrient required in small amounts" When we read the rest of the article, we realize that what small means is actually the root of the debate on vitamin C (emphacized two sentences later). Small amounts, yes: smaller than protein, lipids, and sugars, yes. But as small as other vitamins ? It would be partial (biased) to let this be suggested. The reference provided in the section "Natural mode of synthesis" :
Milton, K. (1999) "Nutritional characteristics of wild primate foods: do the diets of our closest living relatives have lessons for us?" Nutrition. 1999 Jun;15(6):488-98.
which supports:
Most simians (higher primates who cannot produce vitamin C) consume the vitamin in amounts 10 to 20 times higher than that recommended by governments for humans.
Has its importance. If we accept that vitamin will mean "small amounts" in this case as well, without perceiving the very problem caused by this choice of words, we are not neutral. I would suggest something like the following: instead of:
Vitamin C or L-ascorbic acid is an essential nutrient required in small amounts in order to allow a range of essential metabolic reactions in animals and plants. Vitamin C is widely known as the vitamin that prevents scurvy in humans. The joint US-Canadian Dietary Reference Intake recommends 90 milligrams per day and no more than 2 grams per day (2000 milligrams per day), although the amount that humans require for optimum health is a matter of on-going debate.
I suggest:
Vitamin C or L-ascorbic acid is essential to allow a range of essential metabolic reactions in animals and plants. The unability to produce vitamin C (gulonolactone oxidase deficiency) is rare (ref avail.) . It is shared by all great apes/primates/simians, including humans. The former consume vitamin C in amounts 10 to 20 times higher than what the latter consume. The amount that humans require is a matter of on-going debate. Vitamin C is most widely known as the vitamin, which, in small amounts, prevents scurvy.
The following research, which also summarizes earlier results by others, poses well the problem that we are facing when speaking of vitamin C: Comp Biochem Physiol A Mol Integr Physiol. 2003 Sep;136(1):47-59. Micronutrient intakes of wild primates: are humans different? Milton K. Department of Environmental Science, Policy and Management, Division Insect Biology, University of California, Berkeley, CA 94720-3112, USA. kmilton@socrates.berkeley.edu Low micronutrient intake is implicated in a diversity of human health problems, ranging from problems associated with food insufficiency to those associated with food over-consumption. Humans are members of the order primates, suborder anthropoidea, and are most closely related to the great apes. Humans and apes are remarkably similar biologically. In the wild, apes and monkeys consume diets composed largely of plant foods, primarily the fruits and leaves of tropical forest trees and vines. Considerable evidence indicates that the ancestral line giving rise to humans (Homo spp.) was likewise strongly herbivorous (plant-eating). The wild plant parts consumed by apes and monkeys show moderate to high levels of many minerals and vitamins. The estimated daily intake of specific minerals, vitamin C and some other vitamins by wild primates is often quite high in comparison to intake levels of these same micronutrients recommended for humans. Are the high micronutrient intakes of wild primates simply a non-functional, unavoidable by-product of their strongly plant-based diets or might they actually be serving important as yet undetermined immunological or other beneficial functions? A better understanding of the basis for this apparent difference between humans and wild primates could help to clarify the range and proportions of micronutrients best suited for optimal human development, health and longevity.

Chemotherapy interaction
