- Most people obtain vitamin C through diet or oral supplements. However, the body tightly regulates plasma levels, and intestinal absorption drops sharply when high doses are taken orally.
- Because vitamin C is water‑soluble, excess amounts are excreted, limiting the achievable blood concentration.
- Intravenous (IV) therapy bypasses the gastrointestinal tract, allowing clinicians to deliver much higher doses directly into the bloodstream.
- IV administration can produce plasma concentrations up to 100 times higher than oral supplementation.
- These high levels are hypothesized to provide enhanced antioxidant and immune‑modulating effects.
