Vitamin C Injections and Their Purpose
Injections of vitamin C raise a simple question for East Sacramento readers: what is the shot for? This page starts with what the vitamin does in the body, then looks at how the route of delivery changes the picture. For a general look at infusions, see Cleveland Clinic's article on the pros and cons of intravenous vitamin infusion.
What vitamin C does in the body
MedlinePlus says vitamin C is needed for the growth and repair of tissues in all parts of your body.
MedlinePlus lists several uses. It says vitamin C is used to form an important protein called collagen, used to make skin, tendons, ligaments, and blood vessels. It also says vitamin C is used to heal wounds and form scar tissue, to repair and maintain cartilage, bones, and teeth, and to aid in the absorption of iron.
Why the route matters
Acibadem sets out the absorption numbers. The gut absorbs 70–90% of moderate vitamin C intakes, and the kidneys excrete most of an intravenous surge within hours, so faster entry does not mean longer effect.
For a closer look at the high-dose end of the question, a systematic review covers the clinical benefits and risks of high-dose intravenous vitamin C.
Two cautions at high doses
Acibadem also flags two cautions. It says high-dose intravenous vitamin C is converted to oxalate and can raise kidney stone risk, and can trigger red-cell breakdown in undiagnosed G6PD deficiency.
Reading the menu
An infusion menu can read like a list of benefits. UNC Media Hub's report on IV vitamin therapy and its wellness cocktails is a useful second read alongside the numbers above.
Questions for your clinician
Two questions follow from the figures above. Would swallowed vitamin C meet the same goal, given how much the gut absorbs? And have you been tested for G6PD deficiency? A licensed clinician can answer both for your own case.
One last read before you book
Acibadem's piece on IV vitamin therapy and the Myers' cocktail, and the evidence behind them is worth finishing before you pick a treatment.
