Vitamin C, technical name ascorbic acid is a water-soluble vitamin present in certain foods but that can also be obtained through supplementation.
Humans are different from other animals in that they can’t synthesize the vitamin by their own bodies but must get it elsewhere.
The Benefits Of Vitamin C
• We need vitamin C in order to make L-carnitine, collagen and some neurotransmitters.
• Vitamin C is also involved in the metabolism of protein.
• We need vitamin C for the formation of collagen that is part of the connective tissue in the body’s organs and plays a role in wound healing.
• Vitamin C is also a good antioxidant, which makes it good in preventing cancer. It has the important role of regenerating other antioxidants in the body.
• There is research going on that looks into whether or not vitamin C is definitely linked to its antioxidant properties or whether there is something else going on that makes this a good cancer fighter.
• Oral vitamin C produces tissue and plasma concentrations that are tightly controlled. As a water-soluble nutrient, it is excreted by the urine.
Recommended Intake of Vitamin C
The dietary intake of vitamin C has been set up by the Food and Nutrition Board. It sets up the Daily Reference Intakes for all types of nutrients.
According to this board, the recommended intake of vitamin C includes the following:
• Ages 0-6 months, the intake should be 40 mg per day
• Ages 7-12 months, the intake should be 50 mg per day
• Ages `1-3 years, the intake should be 15 mg per day
• Ages 4-8 years, the intake should be 25 mg per day
• Ages 9-13 years, the intake should be 45 mg per day
• Ages 14-18, the intake should be 75 mg per day

Other forms of vitamin C supplements include calcium ascorbate, sodium ascorbate, ascorbic acid with bioflavonoids, dehydroascorbate, xylonate, threonate, and calcium ascorbate.
A few research studies using human participants found that the bioavailability is different depending on the form of vitamin C used.
Other studies have indicated that there are no differences in the bioavailability of the various types of vitamin C. These vitamins are all extremely cheap and can be used to indicate the individual’s vitamin intake.
Vitamin C Deficiency
Vitamin C deficiency results in scurvy.
The timeline for getting scurvy depends on the body’s initial stores of the vitamin in the body to begin with. Signs begin to show up within a month of withdrawing all vitamin C from the diet. Symptoms start out with tiredness, malaise, and other flu-like symptoms.
