Vitamin C is a strong antioxidant that can boost your blood antioxidant levels. This may help reduce the risk of chronic diseases like heart disease.

Vitamin C is a powerful antioxidant that can strengthen your body’s natural defenses².

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 diseases³.

Studies show that consuming more vitamin C can increase your blood antioxidant levels by up to 30%. This helps the body’s natural defenses fight inflammation ^4,5

Vitamin C supplements have been found to lower blood pressure in both healthy adults and those with high blood pressure.

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 levels⁶.

Moreover, an analysis of 29 human studies found that taking a vitamin C supplement reduced systolic blood pressure (the upper value) by 3.8 mmHg and diastolic blood pressure (the lower value) 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 average⁷.

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.

Vitamin C supplements have been linked to a reduced risk of heart disease. These supplements may lower heart disease risk factors, including high blood levels of LDL (bad) cholesterol and triglycerides.

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 supplement⁸.

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 ⁹.

Vitamin-C-rich foods and supplements have been linked to reduced blood uric acid levels and lower risk of gout.

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 least¹⁰.

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 risk¹¹.

Additionally, an analysis of 13 studies found that taking a vitamin C supplement over 30 days significantly reduced blood uric acid, compared with a placebo¹².

While there appears to be a strong link between vitamin C intake and uric acid levels, more studies on the effects of vitamin C on gout are needed.

Vitamin C can improve the absorption of iron that is poorly absorbed, such as iron from meat-free sources. It may also reduce the risk of iron deficiency.

Vitamin C supplements can help improve the absorption of iron from the diet. Vitamin C assists in converting iron that is poorly absorbed, such as plant-based sources of iron, into a form that is easier to absorb¹³.

This is especially useful for people on a meat-free diet, as meat is a major source of iron.

Consuming 100 mg of vitamin C may improve iron absorption by 67%¹⁴.

As a result, vitamin C may help reduce the risk of anemia among people prone to iron deficiency.

In one study, 65 children with mild iron deficiency anemia were given a vitamin C supplement. Researchers found that the supplement alone helped control their anemia¹⁵.

Vitamin C may boost immunity by helping white blood cells function more effectively, strengthening your skin’s defense system, and helping wounds heal faster.

Vitamin C helps encourage the production of white blood cells known as lymphocytes and phagocytes, which help protect the body against infection¹⁶.

Vitamin C helps these white blood cells function more effectively while protecting them from damage by potentially harmful molecules, such as free radicals.

Vitamin C is an essential part of the skin’s defense system. It’s actively transported to the skin, where it can act as an antioxidant and help strengthen the skin’s barriers¹⁷.

Studies have also shown that taking vitamin C may shorten wound healing time¹⁸.

Low vitamin C levels have been linked to an increased risk of memory and thinking disorders like dementia, while a high intake of vitamin C from foods and supplements has been shown to have a protective effect.

Studies suggest that oxidative stress and inflammation near the brain, spine, and nerves (altogether known as the central nervous system) can increase the risk of dementia¹⁹.

Vitamin C is a strong antioxidant. Low levels of this vitamin have been linked to an impaired ability to think and remember²⁰.

Several studies have shown that people with dementia may have lower blood levels of vitamin C²¹.

High vitamin C intake from food or supplements has been shown to have a protective effect on thinking and memory as you age²²
