What are the benefits of Vitamin C? The health benefits of vitamin C, also known as ascorbic acid, include the prevention and treatment of scurvy, common cold, lead toxicity, and cancer. Vitamin C helps to strengthen the immune system, reduce hypertension, cure cataracts, combat strokes, maintain skin elasticity, heal wounds and control asthma.


Vitamin C or ascorbic acid is one of the most efficient and reliable nutrients. It is a water-soluble vitamin and a powerful antioxidant in the synthesis of collagen, which helps to make blood vessels and muscles strong. The entire human body does not have the power to produce vitamin C. Therefore, it must be ingested through foods and other dietary supplements.

30 Proven Health Benefits of Vitamin C

1. What are the Benefits of Vitamin in preventing colds?

Vitamin C strengthens the immune system of our body, which protects us from cold and coughing. It facilitates the absorption of iron and thus strengthens the body’s resistance to infections. It also fights viruses.

2. What are the Benefits of Vitamin C for Combats stroke?

Vitamin C helps reduce the risk of stroke, a type of cardiovascular disease. A diet full of vegetables and fruits provides a good amount of this vitamin, which maintains adequate blood pressure. It also protects the body from free radicals that can cause a stroke.

3. What are the Health Benefits of Vitamin C to fight high blood pressure?

According to a report by Johns Hopkins Medicine, high doses of vitamin C can lower blood pressure. This function of vitamin C can be attributed to its physiological and biological effects. Vitamin C acts as a diuretic and causes the kidneys to remove more sodium and water from the body – relieving pressure on the vascular walls.

Vitamin C also protects the body’s nitric oxide supply, a molecule known to relax blood vessels. The antihypertensive effect can also be attributed to dietary supplements – taking 500 mg per day of vitamin C supplements could lower systolic blood pressure by 4 points and diastolic blood pressure by 1.5 points over a period of 2 months.

Vitamin C, according to another Italian study, also improves vasodilatation (the dilatation of blood vessels that lowers blood pressure). And it even prevents vasoconstriction.

4. What are the Benefits of Vitamin C to reduce the inflammation of the heart arteries?

Collagen is a structural protein in our skin and other connective tissues. Basically, it is the protein that our body makes to “glue” all the cells and tissues in our body together. In order to reduce inflammation in the heart arteries, our body must produce collagen in sufficient quantities, which is possible through a good intake of vitamin C.

5. What are the Benefits of Vitamin C to reduce the risk of dementia?

Vitamin C is a very good antioxidant. It is known that antioxidants reduce the risk of dementia and delay the process of cognitive aging. Vitamin C dissolves amyloid plaques, which are dementia-inducing toxic protein in our brain.

9. What are the Benefits of Vitamin C in preventing cataracts (eye diseases)?

Numerous laboratory studies have shown that high doses of vitamin C can slow the growth of prostate, liver, bowel and other cancer cells. Higher concentrations of vitamin C may also help in cancer treatment.

Intravenous administration of a type of vitamin C to inoperable patients with cancer led to a significant reduction in tumor volume without side effects. Ascorbate also killed cancer cells, as has been found in numerous studies. Another report from Cornell University had found that vitamin C stops aggressive colon cancer.

11. What are the Benefits of Vitamin C in strengthening immunity?

Vitamin C deficiency reduces the body’s resistance to certain pathogens. According to a study, vitamin C stimulates the immune system by increasing the strength and protection of the organism.

In addition to protecting the immune system, vitamin C also reduces the severity of various allergies and fights infections. This is achieved by enhancing T-cell proliferation in response to infection. It has also been found that people who suffer from wounds can accelerate their healing process by taking an optimal dose of vitamin C. The nutrient had improved the quality of the newly synthesized collagen and thus accelerated the process of wound healing.

And for colds, although more research is needed, vitamin C was found to reduce the duration of the cold. We don’t know yet whether the vitamin can protect against a cold – but it certainly reduces the duration of the cold.

12. What are the Benefits of Vitamin C in repairing wounds?

Vitamin C helps to heal wounds. It facilitates the growth of connective tissue, which accelerates the process of wound healing.

13. What are the Benefits of Vitamin C in protecting against gout attacks?

14. What are the Benefits of Vitamin C in preventing scurvy?

Scurvy is a disorder characterized by weakness, sore limbs, fatigue, and frizzy hair. It can also lead to bleeding, gum disease and a decrease in red blood cells. These symptoms can become very severe. Ultimately, scurvy is fatal if left untreated. Usually, death is the consequence of complications from infection or bleeding.

Scurvy is the direct result of a lack of vitamin C, a relationship that has been well documented throughout history. Fortunately, you are unlikely to develop scurvy as it takes a month or more of minimal or no vitamin C in your diet before symptoms appear.

However, it is known to occur in alcoholics (this is rare), and can sometimes occur in older people who are unable to live properly without help.

Sometimes scurvy is also observed in patients with mental disorders. In short, anyone who cannot feed themselves can still develop scurvy.

18. What are the Benefits of Vitamin C in treating preeclampsia?

According to an American study, vitamin C can help in the treatment of pre-eclampsia (high blood pressure during pregnancy). However, further studies are justified. Oxidative stress can also be responsible for pre-eclampsia. And since vitamin C helps combat oxidative stress, it can also help prevent this condition.

19. What are the Benefits of Vitamin C maintaining healthy gums?

A vitamin C deficiency can also lead to periodontal disease, a severe form of gingivitis (gum disease). A low vitamin C content can weaken the connective tissue and easily break down the capillaries.

The antioxidant properties of vitamin C play a role in collagen synthesis and help treat sunburn. The oral intake of vitamin C or the external application of vitamin C oil can help to improve the condition.

A good way to treat eczema is a combination of vitamin C and zinc – the daily intake of 500 to 1000 mg vitamin C and 15 mg zinc can positively influence the healing process.

25. What are the Benefits of Vitamin C in promoting hair growth?

A low intake of vitamin C can be a cause of a number of hair-related problems that affect our hair growth. Vitamin C deficiency can cause dry hair and splitting. These conditions are unfavorable for regular hair growth and eventually lead to hair loss.

When our body converts food that we consume to produce energy into glucose, free radicals are naturally produced. Those free radicals can damage our hair by weakening it, making it brittle and thin, which interrupts hair growth. The antioxidant properties of vitamin C reduce the formation of free radicals and minimize their effect on our body. A sufficient intake of vitamin C in our diet is essential for antioxidant protection against free radicals.

People who take large amounts of vitamin C have healthy, strong and thick hair.

Bone loss is associated with oxidative stress, but vitamin C supplementation has been shown to be protectionist.
