7 Impressive Ways Vitamin C Benefits Your Body

Vitamin C is an essential vitamin, meaning your body can’t produce it. Yet, it has many roles and has been linked to impressive health benefits.

It’s water-soluble and found in many fruits and vegetables, including oranges, strawberries, kiwi fruit, bell peppers, broccoli, kale, and spinach.

The recommended daily intake for adults, for vitamin C is 80mg.

While it’s commonly advised to get your vitamin C intake from foods, many people turn to supplements to meet their needs.

Here are 7 scientifically proven benefits of taking a vitamin C supplement.

1. May reduce your risk of chronic disease

Vitamin C is a powerful antioxidant that can strengthen your body’s natural defences.

Antioxidants are molecules that boost the immune system. They do so by protecting cells from harmful molecules called free radicals.

When free radicals accumulate, they can promote a state known as oxidative stress, which has been linked to many chronic diseases.

Studies show that consuming more vitamin C can increase your blood antioxidant levels by up to 30%. This helps the body’s natural defences fight inflammation.

2. May help manage high blood pressure

Around one in three adults in the UK has high blood pressure.

High blood pressure puts you at risk of heart disease, the leading cause of death globally.

Studies have shown that vitamin C may help lower blood pressure in both those with and without high blood pressure.

An animal study found that taking a vitamin C supplement helped relax the blood vessels that carry blood from the heart, which helped reduce blood pressure levels.

Moreover, an analysis of 29 human studies found that taking a vitamin C supplement reduced systolic blood pressure by 3.8 mmHg and diastolic blood pressure by 1.5 mmHg, on average, in healthy adults.

In adults with high blood pressure, vitamin C supplements reduced systolic blood pressure by 4.9 mmHg and diastolic blood pressure by 1.7 mmHg, on average.

While these results are promising, it’s not clear whether the effects on blood pressure are long term. Moreover, people with high blood pressure should not rely on vitamin C alone for treatment.

3. May lower your risk of heart disease

Heart disease is the leading cause of death worldwide.

Many factors increase the risk of heart disease, including high blood pressure, high triglyceride or LDL (bad) cholesterol levels, and low levels of HDL (good) cholesterol.

Vitamin C may help reduce these risk factors, which may reduce heart disease risk.

For example, an analysis of 9 studies with a combined 293,172 participants found that after 10 years, people who took at least 700 mg of vitamin C daily had a 25% lower risk of heart disease than those who did not take a vitamin C supplement.

Interestingly, another analysis of 15 studies found that consuming vitamin C from foods — not supplements — was linked to a lower risk of heart disease.

However, scientists were unsure whether people who consumed vitamin C rich foods also followed a healthier lifestyle than people who took a supplement. Thus, it remains unclear whether the differences were due to vitamin C or other aspects of their diet.

Another analysis of 13 studies looked at the effects of taking at least 500mg of vitamin C daily on risk factors for heart disease, such as blood cholesterol and triglyceride levels.

The analysis found that taking a vitamin C supplement significantly reduced LDL (bad) cholesterol by approximately 7.9 mg/dL and blood triglycerides by 20.1 mg/dL.

In short, it seems that taking or consuming at least 500mg of vitamin C daily may reduce the risk of heart disease. However, if you already consume a vitamin-C-rich diet, then supplements may not provide additional heart health benefits.

4. May reduce blood uric acid levels and help prevent gout attacks

Gout is a type of arthritis that affects approximately one in four UK adults.

It’s incredibly painful and involves inflammation of the joints, especially those of the big toes. People with gout experience swelling and sudden, severe attacks of pain.

Gout symptoms appear when there is too much uric acid in the blood. Uric acid is a waste product produced by the body. At high levels, it may crystallize and deposit in the joints.

Interestingly, several studies have shown that vitamin C may help reduce uric acid in the blood and, as a result, protect against gout attacks.

For example, a study including 1,387 men found that those who consumed the most vitamin C had significantly lower blood levels of uric acid than those who consumed the least.

Another study followed 46,994 healthy men over 20 years to determine whether vitamin C intake was linked to developing gout. It found that people who took a vitamin C supplement had a 44% lower gout risk.

Additionally, an analysis of 13 studies found that taking a vitamin C supplement over 30 days significantly reduced blood uric acid, compared with a placebo.
