Here's what a high-dose vitamin C IV is, how it works and who it's for. ## What Is Vitamin C? Vitamin C (ascorbic acid) is an essential nutrient your body can't make on its own. It plays important roles in: - Normal immune function - Antioxidant protection - Collagen production for skin and connective tissue - Iron absorption ## Why Oral Vitamin C Has Limits When you take vitamin C by mouth, your gut controls how much gets absorbed.
