8 Amazing Health Benefits of Vitamin C Beyond Immunity Support

What Experts Say About Vitamin C Benefits

Dr. Joel Fuhrman, MD, notes;

“Vitamin C is indispensable for iron absorption, making it crucial for preventing anemia, especially in plant-based diets. It also contributes significantly to healthy vision and has been studied for its potential in supporting cardiovascular health by improving endothelial function.”

What Are The Benefits of Vitamin C Beyond Immunity?

1. Cardiovascular Health

Did you know that your vitamin C intake can play a pivotal role in the onset of cardiovascular disease? Current research suggests that a vitamin C deficiency is associated with a higher risk of mortality from cardiovascular disease, and that vitamin C may improve lipid profiles in some individuals, especially those with low vitamin C levels in their blood.

However, the current literature provides little support for the widespread use of vitamin C supplementation to reduce cardiovascular disease risk or mortality unless you have a deficiency, or if your dietary pattern does not regularly include a variety of foods high in vitamin C.

If you’re not sure what your vitamin C status is, getting a fasting blood sample at your next checkup can help you determine if a vitamin C supplement is right for you in order to promote heart health.

2. Joint Health and Anti-Aging Benefits

Vitamin C is needed for collagen synthesis, which is essential for healthy joints. Vitamin C's anti-inflammatory properties may also help fight inflammation, helping to prevent or reduce joint pain, specifically for those who suffer from osteoarthritis.

Vitamin C has also been shown to have anti-aging benefits, with its powerful antioxidant effects working to fight oxidative stress and age-related disorders. The benefits are also seen in aging skin and wrinkles. Ensuring you’re getting enough vitamin C can help make aging a little less daunting.

3. Skin Health

Healthy skin contains high concentrations of vitamin C, which stimulates collagen synthesis and assists in antioxidant protection against UV damage. Skin cells depend on vitamin C for the production of collagen, and for the regulation of the collagen/elastin balance in the skin layer.

Good skin health is positively associated with fruit and vegetable intake, meaning the more produce you eat the better your skin health is. Vitamin C also promotes wound healing and reduces raised scar formation after an injury or surgery.

4. Iron Absorption and Anemia

Vitamin C promotes the absorption of non-heme iron found in plant based foods. This is particularly important if you follow a plant focused eating pattern, which is the case for a vegan, or vegetarian.

Iron is important as it is found in red blood cells and transports oxygen throughout the body through the bloodstream. Iron is a vital nutrient of concern among vegan eating patterns, as it’s harder for the body to absorb non-heme iron with an absorption rate of 2-10%.

Sources of heme iron such as meat, fish and poultry are absorbed by the body at 15-35%, making it considerably easier to meet your iron needs. A well-balanced plant focused diet can provide enough iron as long as you’re pairing your non-home iron sources such as beans, nuts, seeds, etc, with vitamin C to help promote absorption and prevent iron deficiency anemia.

5. Brain Function

Research has shown that a vitamin C deficiency negatively affects brain function particularly during development, and regeneration following traumatic brain injury when blood flow to part of the body is restricted which leads to a lack of oxygen.

The antioxidant power of vitamin C can help protect the brain from tissue damage caused when the blood supply returns to tissue after a period of lack of oxygen. Vitamin C plays a unique role in the release and synthesis of neurotransmitters, including dopamine, norepinephrine, and acetylcholine all of which are important messengers that help your body function optimally.

6. Eye Health

Vitamin C supports eye health by protecting blood vessels and acting as an antioxidant. Diets rich in fruits and vegetables with vitamin C are linked to a lower risk of cataracts and age-related macular degeneration (AMD).

However, the benefits come primarily from whole foods, as supplements alone are unlikely to prevent these conditions. A balanced, colorful diet is the best way to naturally support healthy vision.

7. Supports Healthy Blood Pressure

High blood pressure affects nearly half of U.S. adults and is a major risk factor for heart disease. Some studies show that vitamin C supplements can help relax blood vessels, potentially leading to modest reductions in both systolic and diastolic blood pressure.

It's important to note that vitamin C should not replace prescribed blood pressure treatments but may complement a heart-healthy lifestyle.

8. Lowers Uric Acid and Supports Gout Management

Gout is a type of arthritis that causes intense pain, swelling, and inflammation, often in the big toe. It’s triggered by high uric acid levels in the blood, which can form crystals in the joints and cause painful attacks.

Vitamin C may help lower uric acid levels. One study showed that higher vitamin C intake is independently associated with a lower risk of gout. Supplemental vitamin C intake may be beneficial in the prevention of gout.

Vitamin C supplements can consistently lower uric acid levels in just a month. While more research is needed to confirm its long-term benefits, getting enough vitamin C through diet or supplements may help support uric acid management and joint health.

How Much Vitamin C Should You Take Daily?

The daily recommended dietary allowance for vitamin C is 90 mg for men, and 75 mg for women 19 years and older. To give you some perspective, ½ cup of red bell pepper provides 95 mg of vitamin C. One orange, provides 70 mg of vitamin C, so if you’re eating pattern includes adequate amounts of fruits and vegetables you wouldn’t need to supplement to meet your needs

Individuals who require more vitamin C include smokers, and women who are pregnant or breastfeeding. Smokers require 35 mg more per day than non-smokers. If you don’t regularly consume 3 cups of vegetables and 2 cups of fruit each day, a dietary supplement may be in your best interest to promote overall health and wellbeing.

If you do choose to use a vitamin C supplement, look for one that contains approximately 90 mg, and ensure it’s third party certified to ensure safety, purity and accuracy.

Conclusion

The immune-supporting properties of vitamin C are famous, although the list of good effects of this nutrient goes much further than cold prevention.

Vitamin C, as an important antioxidant, helps maintain heart and joint health, collagen production to achieve a healthy skin and aging, and enhancement of iron absorption to avoid anemia, and plays a significant role in brain function.

A well-balanced diet with fruits and vegetables usually provides enough vitamin C, but some may need more. Including vitamin C-rich foods supports health and strength. Understanding its benefits can help you make better dietary and supplement choices for a stronger, healthier body.
