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 (1).
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 defenses (2).
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 (3Trusted Source).
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 (4Trusted Source, 5).
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.
2. May help manage high blood pressure
Approximately one-third of American adults have high blood pressure (6Trusted Source).
High blood pressure puts you at risk of heart disease, the leading cause of death globally (7Trusted Source).
Studies have shown that vitamin C may help lower blood pressure in both those with and without high blood pressure.
