The Top Vitamin C Food

Vitamin C is more than just a nutrient; it is a pillar of health and a foundation for our well-being. The remarkable thing about Vitamin C is it is readily available in a large portion of our daily foods! Most of the time, this is sufficient to meet your daily requirements and more! Just by eating a balanced and varied diet, you can get all the vitamin C your body needs every day.

Vitamin C has long been associated with protecting us from the common cold, and when it was discovered in 1932, it was primarily used to prevent scurvy in sailors. It now provides numerous health benefits, ranging from wound healing to infection prevention and even skin health, as it acts as an antioxidant, protecting the body from free radical damage. Incorporating vitamin C-rich foods into your diet will help you absorb enough iron to let your body function optimally. Welcome to our investigation into Vitamin C Food.This blog will cover what Vitamin C is, its numerous health benefits, and which foods have the highest concentrations of vitamin C to help you meet the recommended dietary allowance.

Eat plenty of fruit and vegetables high in Vitamin C.

What is Vitamin C or Ascorbic Acid?

Vitamin C, ascorbic acid, or L-ascorbic acid is a water-soluble vitamin. It is essential for many physiological processes in the human body. It is essential for immune system support, wound healing, iron absorption, and antioxidant protection against free radical damage.

Vitamin C cannot be created in the body and must be supplied regularly by diet or supplementation. Tomatoes, citrus fruits, Brussels sprouts, strawberries, broccoli, kiwi, and bell peppers are all good sources of vitamin C.

Vitamin C is part of a variety of biochemical events in the body, including the creation of neurotransmitters, hormones, and certain enzymes.

Health Benefits of Vitamin C

Antioxidant Properties:

Vitamin C is an effective antioxidant that helps neutralize damaging free radicals, these are unstable chemicals that can cause oxidative damage to cells and contribute to aging and disease. Vitamin C, by scavenging free radicals, protects cells and promotes overall health.

Immune Support: 

Vitamin C strengthens the immune system by increasing the activity of immune cells such as neutrophils, lymphocytes, and macrophages. It promotes the development of white blood cells, antibodies, and cytokines, all of which are required to combat infections and illnesses.

Collagen Synthesis: 

Vitamin C is required for the production of collagen. This is a structural protein in connective tissues, skin, bones, and blood vessels. Collagen provides tissue strength and suppleness, facilitates wound healing, and helps maintain healthy skin, hair, and nails.

Wound Healing: 

Vitamin C aids in wound healing by stimulating collagen synthesis and tissue repair. It promotes the creation of new blood vessels and strengthens the immunological response to injuries, therefore, accelerating the healing process.

Iron Absorption: 

Vitamin C increases the absorption of nonheme iron.  This is in plant-based meals and iron supplements. Vitamin C promotes iron absorption in the intestines by converting it from ferric to ferrous form, which is especially advantageous for people who are at risk of iron deficiency or anemia.

Cardiovascular Health: 

Vitamin C may promote blood vessel dilatation, reduce oxidative stress, and improve endothelial function. Consuming more Vitamin C or having higher blood levels of vitamin C may reduce the risk of heart disease and stroke.

Eye Health: 

Vitamin C, along with other vitamins such as Vitamin E and beta-carotene, may help protect against age-related macular degeneration (AMD) and cataracts, two prevalent eye disorders that can cause vision loss. These strong antioxidants destroy free radicals and protect the eyes from oxidative damage.

Vitamin C Intake

What is the recommended dietary Vitamin C intake for an adult? How much Vitamin C do you need and how much is too much?

The Food and Nutrition Board of the National Academies of Sciences, Engineering, and Medicine created the Recommended Dietary Allowance (RDA) for Vitamin C, which offers basic limits for daily consumption.

Adults (aged 19 and up): 

The RDA for Vitamin C is 90 milligrams per day for men and 75 milligrams per day for women. Pregnant women usually require 85 milligrams per day, while lactating mothers may need 120 milligrams per day.

Adolescents (14 to 18 years old): 

The recommended daily allowance for Vitamin C for adolescents is 75 milligrams for both males and females. 

Children (ages 1 to 13 years): 

The recommended daily intake of Vitamin C varies with age. For example, children aged 4 to 8 years need 25 milligrams per day, whereas children aged 9 to 13 years need 45 milligrams per day.

Infants (ages 0 to 12 months): 

The Adequate Intake (AI) of Vitamin C for infants is calculated depending on the average intake of healthy breastmilk. During the first year of life, newborns usually get enough Vitamin C from breast milk or infant formula. Breast milk contains Vitamin C, which rises as the infant gets older. However, the recommended intake for infants aged 7 to 12 months is 50 mg of Vitamin C each day.

However, more Vitamin C isn’t necessarily better for you. Your intestines absorb it, and once 1000mg is absorbed, it will be absorbed at 50% less capacity. When you ingest high doses, the excess is generally excreted causing no harm to the body. However, there are cases where higher Vitamin C intake has caused adverse effects, therefore it is advised to not exceed the daily recommended dosages. 

Health professionals suggest that taking 2000 mg daily is the highest amount you can take without causing any risk to yourself. Taking more than 3000mg of Vitamin C creates kidney stones, especially for those with a chronic disease like kidney disease. People with gout find that uric acid starts to increase in their bodies if they take too much Vitamin C. It could also cause you to absorb too much iron in your blood.

Vitamin C Deficiency

Causes of Vitamin C Deficiency

Vitamin C deficiency, often known as scurvy, can arise as a result of a variety of causes that prevent appropriate Vitamin C consumption or absorption. Although it is not common, it can occur for various reasons.

Health Disorders

Certain health conditions like kidney disease, malabsorption, or cancer can prevent the body from absorbing enough Vitamin C.

Additionally, certain medical problems that impact digestion or nutrient absorption can raise the risk of Vitamin C insufficiency. Examples include gastrointestinal disorders like Crohn’s disease, ulcerative colitis, and celiac disease, as well as ailments that alter the stomach lining or limit acid production.

Restricted Diet

The most prevalent cause of Vitamin C insufficiency is a diet low in Vitamin C-rich foods like fruits and vegetables. Individuals who consume a limited amount of fresh fruits and vegetables, especially those on restricted diets of less than 10mg a day of Vitamin C or with limited access to fresh produce, are at risk of Vitamin C insufficiency. This is when dietary supplements need to be taken.


Passive and active cigarette smoking raises the body’s need for Vitamin C and hastens its depletion through oxidative stress. Smokers are more likely to have Vitamin C insufficiency than nonsmokers, even if they consume an adequate amount of Vitamin C.

Alcohol and Drug Abuse

Chronic alcohol intake can impair the absorption, usage, and storage of Vitamin C in the body. Alcoholics may have poor food habits and decreased nutritional absorption, which increases the risk of Vitamin C deficiency.

Vitamin C Deficiency Symptoms

Constant Infections

Low Vitamin C levels can result in low immune defense in the body so you are more prone to infections. Your recovery time will also be longer because your body isn’t able to cope as readily with the inflammation caused by infections.

Having enough Vitamin C gives you a decreased risk of scurvy.


Due to the inability to absorb enough iron, you may develop anemia. The degree of vitamin deficiency will determine how extreme the shortness of breath, tiredness, and feelings of weakness will be.

Wound Healing and Bruising

A deficiency in Vitamin C results in connective tissue not being made or incomplete. This results in wounds not being repaired properly and getting infected. Vitamin C is required for collagen formation, which is critical to blood vessel integrity. Deficiency can cause weaker blood vessels, which are more susceptible to bruising and bleeding, such as nosebleeds or gum bleeding.


Vitamin C helps to synthesize neurotransmitters like dopamine and norepinephrine, which regulate mood. Deficiency can cause irritation, sadness, and mood swings. This is an extreme emotional response to not feeling physically well and no matter how much rest is taken, it doesn’t make you feel any better.

Fatigue and Weakness

An extreme lack of energy is felt when you have a deficiency in Vitamin C as it is needed to produce energy. Additionally, Vitamin C promotes the production of carnitine, a chemical essential in energy metabolism. Deficiency can cause weariness, weakness, and lethargy. This can hinder your daily life as you lack the strength and motivation to do anything.

Joint and Muscle Pain

Vitamin C aids in the creation of collagen, a protein that gives shape and strength to connective tissues, including joints. Deficiency can cause joint discomfort, stiffness, and edema. Additionally, Vitamin C deficiency can result in muscle weakness, pain, and tenderness.

Decrease in Oral Health

Vitamin C deficiency can cause gingivitis, which is characterized by swollen, inflamed gums that bleed readily, especially while brushing or flossing. In severe cases of Vitamin C deficiency, it could cause a loss of collagen in the gums and jawbone, causing teeth to loosen or fall out.

Vitamin C Supplements

Vitamin C supplements come in a variety of forms, including tablets, capsules, chewable tablets, powders, and liquid formulations. They are often used to enhance overall health and well-being, particularly in people who may not get enough Vitamin C from their diets. Vitamin C supplements are also taken by people who have higher Vitamin C needs owing to various reasons.

If you can’t get enough Vitamin C via food then you need to take a dietary supplement. Make sure you stick to the recommended dosage so that you don’t cause any harm to your body.

Taking more Vitamin C than you should could cause you to experience flatulence, stomach pain, and diarrhea. These symptoms will pass once you stop taking dietary supplements.
