Injectable Vitamin C
IV Vitamin C · Ascorbic Acid (Injectable)
Injectable vitamin C (ascorbic acid) is a parenteral formulation of the essential water-soluble vitamin, administered intravenously (IV) or intramuscularly (IM). Vitamin C is a potent antioxidant and essential cofactor for numerous enzymatic reactions including collagen synthesis, carnitine biosynthesis, and neurotransmitter production. At physiological concentrations, it functions primarily as an antioxidant, but at the supraphysiological plasma levels achievable only through IV administration (>200mg/dL), it exhibits pro-oxidant properties that have been investigated in oncology research.,IV vitamin C can achieve plasma concentrations 30-70 times higher than the maximum achievable through oral supplementation, due to saturable intestinal absorption and renal threshold mechanisms. This pharmacokinetic difference is the primary rationale for injectable administration in clinical and research settings. High-dose IV vitamin C (15-100g) is used in integrative oncology, critical care (sepsis), and severe deficiency states (scurvy), while lower IM doses (500mg-2g) are used for general repletion and wellness.,The clinical evidence base is mixed. IV vitamin C has shown some promise in sepsis trials (CITRIS-ALI, VITAMINS) with inconsistent results, and early-phase oncology studies suggest possible quality-of-life benefits in advanced cancer patients. For scurvy and severe deficiency, injectable vitamin C is well-established. The compound is generally well-tolerated but requires G6PD screening before high-dose use due to risk of hemolytic anemia in deficient individuals.

How it works
As an electron donor, ascorbic acid serves as a cofactor for prolyl and lysyl hydroxylases (essential for collagen synthesis), dopamine beta-hydroxylase (norepinephrine synthesis), and various dioxygenases involved in carnitine biosynthesis and gene regulation via epigenetic demethylation.,At pharmacological IV concentrations (>200mg/dL plasma), ascorbic acid generates hydrogen peroxide extracellularly through auto-oxidation. Cancer cells, which often have low catalase activity, are selectively vulnerable to this oxidative stress, while normal cells with adequate catalase can neutralize H2O2. This is the basis for high-dose IV vitamin C research in oncology.,Ascorbic acid supports immune function by enhancing neutrophil chemotaxis, phagocytosis, and oxidative burst capacity. It also supports lymphocyte proliferation and antibody production, and protects immune cells from oxidative damage during inflammatory responses.

What to expect
Days 1-7: Rapid plasma level elevation after IV/IM dosing. Deficiency symptoms (fatigue, poor healing) begin improving. Subjective energy boost reported by many.

Pharmacokinetics
Storage. Store refrigerated at 2-8C. Protect from light. Ascorbic acid is sensitive to oxidation; discard if solution is darkened or discolored.
Regulatory status
FDA-approved for treatment and prevention of vitamin C deficiency (scurvy) and conditions requiring parenteral supplementation. High-dose IV use in oncology and sepsis is investigational/off-label.
