The deficiency of vitamin C in human beings as well as in some species of birds and fishes, which are not capable to synthesize it, suffer from the disease scurvy. Therefore, the citrus fruits such as orange, kiwi, lemon, guava, grapefruit, papaya, and strawberries, and vegetables such as broccoli, cauliflower, and capsicums, which are rich in ascorbic acid, are highly recommended for daily consumption.

Vitamin C or L-ascorbate, a water-soluble antioxidant that is widely distributed in nature. It is highly abundant in some fruits and vegetables and is also found in animal organs such as the liver and kidney [55, 127]. Usually, fruits and vegetables serve as the main sources of Vitamin C for the human body. Farbstein et al., [55] had explained that Vitamin C is needed for many physiological processes and has shown a great potential in improving immunity performances, as well as lowering the risk of cardiovascular disease and cancer. Vitamin C plays an important role in human health as an antioxidant which can protect the body against oxidative stress [122].

Citrus fruits such as orange, grapefruit, lime and lemon are an abundant source of Asc. Many non-citrus fruits such as strawberries, pineapple, kiwi fruit, blueberries, watermelon, and apple are good sources of Asc. Vitamin C is also found in many vegetables like broccoli, kale, spinach and carrot.

Scurvy is a nutritional disease caused by deficiency of Vitamin C (ascorbic acid). Vitamin C is not produced in the human body, so we are entirely reliant on dietary intake (Hirschman and Raugi 1999; Keenan et al. 2002; Linster and Van Schaftingen 2007). The vitamin is an essential component of several cellular processes including reversing oxidisation from free radicals which cause disease in the body. Vitamin C is also an important contributor to the synthesis of collagen production, an essential building block of connective tissue (Linster and Van Schaftingen 2007). The consequence of Vitamin C deficiency leads to a breakdown of bodily tissues that rely on collagen for structural stability, including blood vessels, skin, muscular tissue, and bone (Hirschman and Raugi 1999). Increased risk of more severe infectious disease is another consequence (Wintergerst et al. 2006) of relevance to the pre-antibiotic era.

The vitamin C derivative known as ascorbic acid 2-glucoside or ascorbyl glucoside (AA-2G) was studied by Hakozaki et al., Hsiao et al., and Lin et al.[11–13] The AA-2G molecule has a conjugated glucose in the carbon-2-hydroxyl which increases the stability of the active, and protects the vitamin C molecule from degradation due to high temperature, pH and metal ions. Once applied topically, AA-2G is hydrolyzed by a cellular α-glucosylase and it is converted to L-ascorbic acid (vitamin C) which then exerts its antioxidant activity. In addition, the vitamin C has been used topically to treat photoaged skin since it is known to increase collagen synthesis, and it has also been reported to decrease melanin synthesis and has therefore been used as a skin whitener. The use of natural raw materials in the production of cosmetics and pharmaceutical products has increased in recent years, verified by the numbers of natural skin care products launched on to the market. Several studies have been published in this regard discussing how natural raw materials can replace synthetic compounds in formulations, how these actives can reduce potential harmful effects, or how they improve the effectiveness of the product.[14,15]
Immune nutrition and exercise: Narrative review and practical recommendations

Of all the potential exogenous antioxidant supplements, the essential nutrient vitamin C has received the greatest attention as a strategy to support immune health in athletes (Nieman et al., 2002b). Initially, interest was also partly due to preliminary evidence of the prophylactic benefit of vitamin C on the common cold. The current evidence, however, provided by the latest Cochrane review, reports that routine vitamin C supplementation (> 0.2 g per day) does not reduce the risk of developing a cold in the general population but such regular supplementation (as opposed to upon onset of symptoms) appears to reduce the duration and severity of colds (Hemilä & Chalker, 2013). In contrast, pre-specified subgroup analysis of trials in this review concluded that there is firm evidence that vitamin C supplementation between 0.25 and 1.0 g/day results in reduced number of participants reporting URS under periods of physical stress with or without cold stress (marathon runners, skiers and soldiers on subarctic operations). The underlying mechanism(s) of such effects remains unclear, particularly as any role of exercise-induced oxidant production in alterations of immune dysfunction has not been shown consistently (Nieman et al., 2002b). Additional evidence has purported benefits of vitamin C in non-infectious causes of URS (e.g. exercise-induced bronchoconstriction) following exercise (Hemila, 2013).
