What You'll Learn
Vitamin C is an essential nutrient for humans
Vitamin C, also known as ascorbic acid, is an essential nutrient for humans. It is needed for the growth and repair of body tissues and has several important functions. Firstly, it is required for the formation of collagen, a protein that is essential for making skin, tendons, ligaments, and blood vessels. Vitamin C is also an antioxidant, which means it helps block some of the damage caused by free radicals in the body. Free radicals are produced during the breakdown of food and exposure to tobacco smoke or radiation, and they contribute to the aging process and the development of various health conditions.
Vitamin C is not produced or stored in the body, so it is important to include vitamin C-rich foods in the diet to maintain healthy levels. The recommended daily intake of vitamin C for adults 19 years and older is 90 mg for men and 75 mg for women, with slightly higher requirements during pregnancy and lactation. Smokers and those exposed to second-hand smoke should also increase their vitamin C intake by an additional 35 mg per day.
Vitamin C is found in a wide variety of fruits and vegetables, with citrus fruits, green peppers, strawberries, tomatoes, broccoli, and potatoes being particularly rich sources. It is best to consume these foods raw or cooked with minimal water to retain the vitamin C content. Vitamin C improves the absorption of iron when consumed together, so pairing vitamin C-rich foods with iron-rich plant foods is beneficial.
While vitamin C deficiency is rare in developed countries, it can occur with a limited diet that provides less than 10 mg of vitamin C daily for an extended period. Scurvy is the hallmark disease of severe vitamin C deficiency, characterized by skin spots, bleeding gums, bruising, and loose teeth. Maintaining a balanced and varied diet that includes vitamin C-rich foods is the best way to ensure adequate intake and promote overall health.

It cannot be stored in the body and must be consumed daily
Vitamin C, also known as ascorbic acid, is an essential nutrient that plays a crucial role in the nervous system and various other functions in the body. It is required for the growth and repair of tissues, the formation of collagen, and the absorption of iron. However, the body cannot produce or store vitamin C, which means it must be consumed regularly as part of a healthy diet.
Vitamin C is a "water-soluble" vitamin, which means it is not stored in the body and needs to be consumed regularly. The Recommended Dietary Allowance (RDA) for adults aged 19 and older is 90 mg daily for men and 75 mg for women. During pregnancy and lactation, these requirements increase to 85 mg and 120 mg, respectively.
It is important to note that vitamin C deficiency is rare in developed countries, but it can occur with a restricted diet that provides less than 10 mg of vitamin C daily for an extended period. Smokers, individuals exposed to secondhand smoke, and those with drug or alcohol abuse issues are at a higher risk of deficiency.
To ensure adequate intake, it is recommended to include vitamin C-rich foods in your daily diet. Citrus fruits, green peppers, strawberries, tomatoes, broccoli, and dark leafy greens are excellent sources of vitamin C. Cooking these foods or exposing them to light can reduce their vitamin C content, so it is advisable to consume them raw or with minimal processing.
In summary, while vitamin C is crucial for maintaining health, it cannot be stored in the body and must be consumed daily through a balanced diet that includes a variety of vitamin C-rich fruits and vegetables.

It is important for the growth and repair of body tissues
Vitamin C, also known as ascorbic acid, is essential for the growth and repair of body tissues. It is a water-soluble vitamin, and the body does not produce or store it. Therefore, it is necessary to include vitamin C in your daily diet to maintain healthy levels.
Vitamin C plays a crucial role in forming collagen, an essential protein that makes up skin, tendons, ligaments, and blood vessels. Collagen provides structure and strength to these connective tissues, helping to keep them healthy and functioning properly. A deficiency in vitamin C can lead to scurvy, characterised by weakness, anaemia, bruising, bleeding, and loose teeth. These symptoms arise from the loss of collagen, which weakens the connective tissues.
Citrus fruits, green peppers, strawberries, tomatoes, broccoli, white potatoes, and sweet potatoes are excellent sources of vitamin C. Other good sources include dark leafy greens, cantaloupe, papaya, mango, watermelon, Brussels sprouts, cauliflower, and cabbage.
To ensure adequate vitamin C intake, it is recommended to consume a balanced diet rich in fruits and vegetables. Cooking or storing vitamin C-rich foods for extended periods can reduce their vitamin C content. Therefore, it is advisable to eat these foods raw or cook them with minimal water to retain the vitamin.
In summary, vitamin C is vital for the growth and repair of body tissues, especially in the formation of collagen. By including vitamin C-rich foods in your daily diet and maintaining a balanced and varied approach to nutrition, you can help support the health and functioning of your connective tissues.

It is an antioxidant that blocks damage from free radicals
Vitamin C, also known as ascorbic acid, is an essential nutrient that plays a crucial role in the human body. One of its key functions is its antioxidant property, which helps block damage caused by free radicals. Free radicals are molecules produced when the body breaks down food or when exposed to environmental factors such as tobacco smoke or radiation.
Over time, the buildup of free radicals can lead to oxidative stress, which has been implicated in various diseases and the aging process. Vitamin C, as an antioxidant, neutralizes these free radicals, preventing them from causing harm to cells and tissues. This protective effect is particularly important in maintaining healthy skin, bones, blood vessels, and connective tissues.
Vitamin C is necessary for the formation of collagen, a vital protein that provides structure and strength to these connective tissues. By blocking the damage caused by free radicals, vitamin C helps preserve the integrity of collagen fibrils, ensuring the proper functioning of skin, tendons, ligaments, and blood vessels. This protective mechanism helps prevent skin spots, bruising, and bleeding caused by weakened blood vessels.
Additionally, vitamin C's antioxidant property may also provide benefits beyond connective tissue health. Research suggests that it may contribute to a reduced risk of certain chronic diseases associated with free radical damage. These include cancer, heart disease, and arthritis. While the exact mechanisms are still being studied, the antioxidant effects of vitamin C offer a promising area of exploration in disease prevention and management.
It is important to note that the body does not produce or store vitamin C. Therefore, it is essential to include vitamin C-rich foods in your daily diet. Citrus fruits, green peppers, strawberries, tomatoes, broccoli, and dark leafy greens are excellent sources of vitamin C. By incorporating these foods into your meals, you can help maintain optimal vitamin C levels and harness its antioxidant benefits to protect your body from free radical damage.

A deficiency in vitamin C can lead to scurvy
Vitamin C, also known as ascorbic acid, is a vital nutrient for human health and well-being. A deficiency in vitamin C can lead to scurvy, a clinical syndrome resulting from insufficient vitamin C intake. Scurvy is a rare but serious condition that requires early diagnosis and treatment. It is characterised by a range of symptoms affecting multiple organ systems.
The human body does not produce vitamin C naturally, nor can it store vitamin C. Therefore, it is essential to include vitamin C in our daily diet. The recommended daily intake for adults aged 19 to 64 is 40mg, which can typically be obtained from a varied and balanced diet rich in fruits and vegetables. For adults over 65, the recommended intake is slightly lower at 30mg for men and 25mg for women. During pregnancy and lactation, the recommended intake increases to 85mg and 120mg, respectively.
A vitamin C deficiency can develop when an individual's diet provides less than 10mg of vitamin C daily for an extended period, usually a month or longer. Scurvy is the hallmark disease of severe vitamin C deficiency and is characterised by symptoms resulting from the loss of collagen, which weakens connective tissues. This can lead to a range of oral and musculoskeletal manifestations, including:
- Gingivitis with bleeding, swollen, and receding gums
- Dental caries
- Bruising
- Arthralgias (joint pain, typically in the knees, ankles, and wrists)
- Muscle aches
- Hematarthrosis
- Muscular hematomas
The deficiency also causes systemic symptoms such as fatigue, muscle weakness, malaise, mood changes, peripheral neuropathy, and vasomotor instability. Early symptoms may include irritability, loss of appetite, and aching pain.
The good news is that scurvy is treatable and preventable. Treatment involves consuming sufficient fruits and vegetables and addressing any underlying causes of malnutrition. Vitamin C supplementation is also an effective way to treat and prevent scurvy.
