Vitamin C (ascorbic acid) is a vitamin necessary for your body to make the protein collagen, which is used to support connective tissue.
It’s necessary to make collagen and a powerful antioxidant, which protects cells from chemical damage. It’s not really the magic immune booster the public thinks it is, but it does help somewhat and doesn’t hurt.
A deficiency in vitamin C results in the inability to produce collage, which is called scurvy. Symptoms of this include bleeding gus and other stuff.
Vitamin C is not stored in your body, and any extra is eliminated fairly quickly in the urine. Given the protective effects of vitamin C, it’s smart to get enough so that your blood has as much as it can. This requires 200mg/day for adult men and women. The recommended intake from the National Institute of Health is only 100mg/day, but since there’s evidence that vitamin C is more and more beneficial up to 200mg/day, and since there is no toxicity associated with excessive intake, I recommend 200mg/day.
It’s found in citrus fruits (why limes were used to cure it) as well as a variety of meats, fruits, and vegetables. It is also very cheap to supplement, so I recommend everyone be on a supplement with vitamin C because it’s good insurance, can be hard to get from the diet, cheap, effective, and safe.
