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 vitamin C is 75 mg for women and 90 mg for men.

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

Approximately one-third of American adults have 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 (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 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.

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