1. Why Is Vitamin C Important?

Vitamin C, also known as L-ascorbic acid, is a water-soluble vitamin crucial for various bodily functions. But why exactly do we need it?

Vitamin C is an essential nutrient because humans cannot synthesize it on their own; we must obtain it through our diet. According to research from the University of California, Berkeley, in July 2025, adequate vitamin C intake supports immune function and promotes vibrant health.

1.1. What Are the Key Benefits of Vitamin C?

Vitamin C is vital for health. Vitamin C is more than just an immune booster; it’s a powerhouse of benefits:

• Collagen Synthesis: Vitamin C is essential for the production of collagen, a protein vital for skin, tendons, ligaments, and blood vessels.
• Antioxidant Protection: It acts as a potent antioxidant, neutralizing harmful free radicals and protecting cells from damage.
• Immune Function: Vitamin C supports the immune system, helping the body fight off infections and illnesses.
• Iron Absorption: It enhances the absorption of nonheme iron, the type of iron found in plant-based foods.

1.2. What Happens if You Don’t Get Enough Vitamin C?

Vitamin C deficiency can lead to scurvy, a condition characterized by fatigue, weakness, and impaired wound healing. Signs of deficiency includes fatigue, inflammation of the gums, impaired collagen synthesis, connective tissue weakness, and capillary fragility. Other symptoms include depression, swollen and bleeding gums, loosening or loss of teeth.

4. What Are the Recommended Daily Intakes of Vitamin C?

Knowing how much vitamin C you need daily is crucial for maintaining optimal health.

4.1. Understanding the Recommended Dietary Allowances (RDAs)

The Food and Nutrition Board (FNB) at the Institute of Medicine (IOM) of the National Academies has established Dietary Reference Intakes (DRIs) for vitamin C. These recommendations vary based on age, gender, and specific conditions:

Smokers need an additional 35 mg of vitamin C per day due to increased oxidative stress.

4.2. Can You Get Too Much Vitamin C?

While vitamin C is generally safe, excessive intake can lead to side effects: Vitamin C has low toxicity.

• Gastrointestinal Issues: High doses can cause diarrhea, nausea, and abdominal cramps.

5. What Are the Health Benefits of Vitamin C?

Vitamin C offers a wide array of health benefits, supported by scientific research.

5.1. Vitamin C and Cancer Prevention

Vitamin C’s antioxidant properties may help prevent cancer by neutralizing free radicals and reducing oxidative damage. Epidemiologic evidence suggests that higher consumption of fruits and vegetables is associated with lower risk of most types of cancer. According to a cohort of 82,234 women from the Nurses’ Health Study, consumption of an average of 205 mg/day of vitamin C from food was associated with a 63% lower risk of breast cancer among premenopausal women with a family history of breast cancer.

However, most randomized clinical trials suggest that vitamin C supplementation, usually in combination with other micronutrients, does not affect cancer risk.

5.2. Vitamin C and Cardiovascular Health

High intakes of fruits and vegetables, rich in vitamin C, are associated with a reduced risk of cardiovascular disease. Oxidative damage contributes to cardiovascular disease.

A prospective study in 20,649 British adults found that those in the top quartile of baseline plasma vitamin C concentrations had a 42% lower risk of stroke than those in the bottom quartile.

5.3. Vitamin C and Eye Health

Vitamin C may play a role in preventing age-related macular degeneration (AMD) and cataracts.

A population-based cohort study in the Netherlands found that adults age 55 years or older who had high dietary intakes of vitamin C as well as beta-carotene, zinc, and vitamin E had a reduced risk of AMD. The Age-Related Eye Disease Study (AREDS) found that high doses of selected antioxidants, including vitamin C, helped slow the progression of advanced AMD.

5.4. Vitamin C and the Common Cold

Vitamin C has been a popular remedy for the common cold for decades.

A 2007 Cochrane Review found that prophylactic use of vitamin C did not significantly reduce the risk of developing a cold in the general population. However, in trials involving marathon runners, skiers, and soldiers exposed to extreme physical exercise and/or cold environments, prophylactic use of vitamin C reduced cold incidence by 50%.

6. How Does Vitamin C Interact With Medications?

Vitamin C supplements can interact with certain medications, affecting their efficacy or increasing the risk of side effects.

6.1. Potential Interactions with Chemotherapy and Radiation

The use of vitamin C and other antioxidants during cancer treatment is controversial. Some data indicate that antioxidants might protect tumor cells from the action of radiation therapy and chemotherapeutic agents. Individuals undergoing chemotherapy or radiation should consult with their oncologist prior to taking vitamin C or other antioxidant supplements, especially in high doses.

6.2. Interactions with Statins

Vitamin C, in combination with other antioxidants, may attenuate the increase in high-density lipoprotein levels resulting from combination niacin–simvastatin (Zocor) therapy. Health care providers should monitor lipid levels in individuals taking both statins and antioxidant supplements.
