Vitamin C stands as one of the most researched antioxidants, playing multiple critical functions in keeping your immune system operating at peak performance. It supports the production and activity of white blood cells, including neutrophils and lymphocytes, which serve as frontline defenders against invading pathogens. By enhancing phagocytosis, the process where immune cells engulf and destroy harmful microbes, Vitamin C helps neutralize threats efficiently. Additionally, this nutrient contributes to maintaining epithelial barriers in the respiratory tract and skin, acting as a physical shield that prevents easy entry for viruses and bacteria. Its potent anti-inflammatory properties help modulate cytokine responses, preventing excessive inflammation that could otherwise prolong discomfort during infections. High-dose delivery through IV allows for concentrations far exceeding what oral intake can achieve, promoting enhanced antioxidant protection that combats oxidative stress generated during immune activation. This oxidative stress, if unchecked, can impair cellular function and delay recovery, making intravenous Vitamin C a strategic tool for those experiencing frequent illnesses or heightened exposure risks.
