Vitamin C, also known as Ascorbic Acid, is an antioxidant with anti-inflammatory properties that play an important role in immune support. It is also a key component in making collagen. High doses of Vitamin C can be given intravenously or orally. When taken through an intravenous infusion, Vitamin C reaches much higher levels in the blood than when the same amount is taken orally. Some studies suggest that higher levels of Vitamin C may aid in killing cancerous cells. These specialty infusions are given with potassium, calcium, and magnesium in sterile water to help maintain fluid and acid/base balance.
