Purpose of vitamin C injections
Many people take vitamin C for general health or to boost their immune system. It’s also taken to treat vitamin C deficiency.
Vitamin C deficiency can lead to scurvy. Characteristic symptoms of vitamin C deficiency include:
swollen and bleeding gums
fatigue
poor wound healing
joint pain
loose teeth
colored spots on the skin
In some cases, signs of scurvy can occur within a month of consuming less than 10 milligrams (mg) per day of vitamin C.
Today, scurvy is rare in developed countries. It’s most likely to occur in people who:
smoke
consume a limited variety of food
have nutrient absorption problems
Vitamin C injections are approved by the U.S. Food and Drug Administration (FDA) for treating vitamin C deficiency. They’re also approved for helping to treat serious wounds from trauma or burns.
