What is Vitamin C?

Vitamin C (also known as ascorbic acid) is a water-soluble vitamin with powerful antioxidant properties. Since Vitamin C is water soluble, it is not stored in your body. Instead, it must be consumed externally through food sources and supplementation. Antioxidants, like Vitamin C, are important for neutralizing “free radicals” in the body. Free radicals are waste products that are created when the body turns food into energy. Due to the high reactivity of free radicals, they often damage cells and organs, making the body weaker. Since antioxidants are used up as they continue to fight free radicals, it is important to replenish them through the consumption of antioxidant rich foods and supplements, like Vitamin C.

What are the benefits of Vitamin C?

Vitamin C is most commonly known for its proven benefits relating to cardiovascular health. Specifically, Vitamin C has reduced plaque buildup in healthy adults by preventing white blood cells from adhering to the walls of blood vessels.[1] Additionally, Vitamin C supplementation has shown to decrease both systolic and diastolic pressure in men and women.[2, 3] Vitamin C has also been show to help lower blood glucose levels and plasma free radicals in diabetics.[4] Vitamin C is also known to boost the immune system. The common cold is reduced in frequency and duration in cases where Vitamin C is taken regularly.[5]

When maintaining a healthy lifestyle, one strives to have a balanced diet and exercise regime. While exercise has an abundance of proven benefits, it can also produce free radicals that in turn have negative effects.[6] Various studies demonstrated how Vitamin C supplementation helps to reduce the oxidative stress caused by exercise, resulting in less muscle soreness and improved muscle function.[7, 8] Vitamin C has also been shown to decrease the oxidative stress and damage that results from smoking tobacco.[9] Vitamin C can help prevent cancer that often results from smoking, by reducing the number of cancer causing DNA damage sites.[10] For cancer patients, Vitamin C may lower the toxicity of chemotherapy drugs while increasing the effectiveness of the chemotherapy itself.[11, 12] Finally, high Vitamin C levels have been correlated with a lower long-term risk of gastric cancer.[13]

Why take Vitamin C supplements?

Vitamin C deficiency can cause many issues in the body from gingivitis to a decreased ability for the body to fight off infections. Although Vitamin C is present in many foods, it can be difficult to consume the necessary serving of fruits and vegetables for your body to get the Vitamin C it needs. Many studies, including those referenced here, suggest that adults should take 250-500mg of Vitamin C twice a day in order to gain the benefits.
