Vitamin C, also called ascorbic acid, is a water-soluble essential vitamin that the human body is unable to synthesise. Therefore, it is necessary to intake vitamin C from dietary sources. Vitamin C performs many vital physiological roles in the body. It is a powerful antioxidant that helps with the prevention of diseases such as diabetes, cataracts, atherosclerosis, heart diseases, and cancer.

Recommended Intake of Vitamin C

According to the National Institute of Health (NIH), the current recommended dietary allowance for vitamin C is as follows:

Age	Male	Female
0-6 months	40 mg	40 mg
7-12 months	50 mg	50 mg
1-3 years	15 mg	15 mg
4-8 years	25 mg	25 mg
9-13 years	45 mg	45 mg
14-18 years	75 mg	75 mg (pregnancy-80 mg, lactation- 115 mg)
19+ years	90 mg	75 mg (pregnancy-85 mg, lactation- 120 mg)
Smokers require 35 mg/day more vitamin C than non-smokers.

Health Benefits of Vitamin C

Fights Against Free Radicals

It is no secret that vitamin C is a powerful antioxidant. Antioxidants assist in strengthening the immune system. It helps to protect the cells from free radicals. Too many free radicals cause oxidative stress that causes various chronic diseases like cancer, Neurodegenerative diseases (such as Alzheimer’s and Parkinson’s), Arthritis, Chronic inflammation and age-related eye conditions (like cataracts and age-related macular degeneration). Vitamin C neutralises free radicals and prevents cellular damage. Studies claim it has free radical scavenging and pro-oxidative factors.

Regulates High Blood Pressure

Vitamin C assists in reducing high blood pressure by acting as a diuretic. It encourages the kidneys to remove excessive sodium and water from the body and relaxes the blood vessel walls, lowering blood pressure. Scientific studies indicate that taking vitamin C supplements can lead to a decrease in both the upper (systolic) and lower (diastolic) numbers of your blood pressure reading. In simpler terms, it can help in lowering both the higher and lower values when you measure your blood pressure.

Fights Heart Diseases

Vitamin C reduces the heart disease risk by lowering high triglycerides or LDL cholesterol levels. It decreases the risks of plaque buildup in arteries, thereby preventing stroke and atherosclerosis. A severe lack of vitamin C resulted in various cardiovascular diseases.

Reduces Blood Uric Acid Levels

The body releases uric acid as a waste product. Its high concentrations have the potential to crystallise and accumulate in the joints, leading to gout. It causes terrible pain and inflammation in the joints. Studies suggest that vitamin C helps in reducing blood uric acid levels and preventing gout.

Prevents Iron Deficiency

Iron absorption and iron metabolism depend on vitamin C. By combining with ferric iron to generate a chelate at an acidic pH that is soluble at the alkaline pH of the duodenum; vitamin C helps the body absorb iron. Essentially, this means that vitamin C stops ferrous iron from oxidising to ferric iron by making the stomach’s pH higher.

Slows Ageing

Vitamin C’s antioxidant qualities are advantageous for preventing ageing. Vitamin C boosts collagen, which prevents skin sagging. When applied to the skin, it helps new collagen turnover. It also protects skin cell protein from getting damaged. Studies have proved vitamin C serum helps to delay ageing and visible signs of biological skin ageing, giving your skin a fresh, bright, young look.

Reduces the Risk of Cancer

Vitamin C, as an antioxidant, helps reduce cancer risk by neutralising harmful free radicals that can damage DNA and lead to cancerous mutations. Additionally, it supports the immune system, aiding in the elimination of cancerous cells. While it’s not a direct cancer preventative, a diet rich in vitamin C can contribute to a reduced cancer risk by promoting cellular health and immune system functionality.

Summary

Vitamin C offers a multitude of health benefits. It functions as a potent antioxidant, combating free radicals and protecting against chronic diseases. Furthermore, it aids in regulating blood pressure, lowering cholesterol levels, and preventing plaque buildup in arteries. Vitamin C also lowers uric acid levels, preventing painful conditions like gout. It promotes iron absorption, preventing iron deficiency, and contributes to youthful skin by boosting collagen production. Moreover, its immune-boosting and DNA-protecting properties make it a valuable factor in reducing cancer risk. Overall, vitamin C is a versatile nutrient that supports overall health and well-being.
