IV vitamin C (ascorbic acid) is a treatment that involves administering high doses of vitamin C directly into the bloodstream. There are many potential benefits of IV vitamin C, including the following:

1. It boosts the immune system. It is a potent antioxidant that improves immunity by fighting against free radicals and reducing inflammation. Intravenous infusion increases the concentration of vitamin C in the blood, thereby enhancing the body’s ability to fight infection and disease. 
2. It reduces inflammation via multiple mechanisms. It helps reduce the free radicals that cause damage to healthy cells. It also decreases the chemical messengers responsible for driving ongoing inflammation.
3. It helps fight cancer. High concentrations of vitamin C in the bloodstream can cause death in cancer cells while leaving the healthy cells unharmed. Studies show that it can also make chemotherapy and radiation more effective. Additionally, it can help reduce the inflammation that contributes to the growth and spread of cancer cells. 
4. It supports skin regeneration and wound healing. Vitamin C is one of the most crucial components of collagen, the part of our skin responsible for elasticity and the ability to heal and repair. For this reason, it is a great addition to any anti-aging regimen. 
5. It decreases symptoms of allergies. Histamine is a chemical that plays an important function in many bodily functions, including inflammation, allergic reactions, stomach acid production, and stress response. When histamine is chronically elevated it can lead to swelling, inflammation, redness, itchiness, emotional irritability, insomnia, and stomach ulcers. Vitamin C is a powerful inhibitor of histamine 

**A word of caution: some studies suggest that a small percentage of IV vitamin C will be metabolized into oxalate, increasing the risk of kidney stones. For patients who are prone to kidney stones it is often preferable to start out with lower doses of vitamin C or choose a different type of IV therapy altogether.
