Elevate Your Vitamin C Levels with Nutrient-Dense Foods Vitamin C, also known as ascorbic acid, is a water-soluble vitamin essential for various bodily functions. It acts as a powerful antioxidant, protecting cells from damage caused by free radicals and supporting the immune system’s function. Vitamin C is crucial for the synthesis of collagen, a protein vital for skin, bones, and connective tissue health. It also aids in the absorption of iron and supports wound healing. Found abundantly in fruits and vegetables such as oranges, strawberries, kiwi, bell peppers, and broccoli, vitamin C is a crucial nutrient that the body cannot produce on its own. Its deficiency can lead to scurvy, characterized by fatigue, swollen gums, and poor wound healing. While a balanced diet usually provides adequate vitamin C, supplementation may be necessary in certain cases, such as during pregnancy, illness, or for individuals with limited dietary intake. Overall, vitamin C plays a vital role in maintaining overall health and well-being. Requierment : Functions : Vitamin C has long been hailed as a prevention and treatment mechanism for all kinds of acute infections, including the common cold. Vitamin C may play a role in both the prevention and treatment of pneumonia. Vitamin C may help support the heart and vascular system by protecting against endothelial dysfunction, preventing heart attacks, and countering the dangerous oxidation of blood lipids. Vitamin C may also play a role in HIV and cancer management. Vitamin C, or ascorbic acid, is a water-soluble vitamin that is perhaps best known for its ability to help ght colds and u. That’s because vitamin C is a powerful antioxidant that neutralizes potentially harmful organisms and enhances the immune system. Vitamin C helps promote healthy teeth and gums, aids in the absorption of iron, helps wound healing, and strengthens blood vessel walls. Deficiency : A severe form of vitamin C deficiency, known as scurvy, is characterized by general weakness, anemia, gum disease (gingivitis), and skin hemorrhage. Scurvy is seen more frequently in older, malnourished patients and is very rare. Smokers have higher vitamin C requirements because of smoking’s ability to increase oxidative stress, and deficiencies are more common in smokers than in non-smokers. Symptoms of vitamin C deficiency include dry and splitting hair, gingivitis, rough, dry skin, decreased wound healing rate, weakened tooth enamel, anemia, and a decreased ability to fight infections. A deficiency of vitamin C can cause scurvy, a disease characterized by bleeding gums, loose teeth, anemia, joint tenderness and swelling, poor wound healing, dry skin, loss of appetite, frequent bruising, and weakness. Scurvy is very rare in the United States; marginally deficient levels of vitamin C, however, are sometimes seen among the elderly, hospitalized patients, and people on very restrictive diets. These individuals often are susceptible to infection and also have slow wound healing. Food sources : Vegetarian Sources : A . Leafy green vegetables (per 100 grams) : B. Amla: 600-800mg C. Broccoli: 89 mg D. Bell peppers (red): 127 mg E. Kiwi: 92 mg F. Broccoli: 89 mg G. Brussels sprouts: 85 mg H. Pineapple: 47 mg I. Mango: 36 mg J. Papaya: 61 mg K. Guava: 228mg L. Strawberry: 59 mg Non-Vegetarian Sources (per 100 grams) : A.Chicken Breast: 2.3 mg B. Eggs: 0.1mg C. Fish: 1 mg Supplements : Over Dosage : According to the Food and Nutrition Board, vitamin C toxicity is very rare, because the body cannot store the vitamin. However, amounts greater than 2,000 mg/day are not recommended because such high doses can lead to stomach upset and diarrhea. There is some concern about the link between high-dose vitamin C supplementation to an increased risk of calcium oxalate kidney stones, but other studies have refuted this link. Conclusion : So, the best choice is to eat a well-balanced diet and get these nutrients from food sources.

Vitamin A is a fat-soluble nutrient essential for various bodily functions. It plays a crucial role in vision, particularly in low-light conditions, by maintaining the health of the retina and promoting good eyesight. Additionally, it supports the immune system by helping the body fight off infections and illnesses. Vitamin A is also important for maintaining healthy skin and mucous membranes, which act as barriers against bacteria and viruses. There are two forms of vitamin A found in food: preformed vitamin A (retinol) and provitamin A carotenoids. Retinol is found in animal products such as liver, eggs, and dairy, while carotenoids are found in colorful fruits and vegetables like carrots, sweet potatoes, and spinach. The body can convert carotenoids into active vitamin A as needed. A deficiency in vitamin A can lead to night blindness, dry skin, and an increased susceptibility to infections. However, excessive intake of vitamin A can be harmful, so it’s essential to consume it in appropriate amounts as part of a balanced diet. Requierment : Functions : Vitamin A serves several vital functions in the human body. Primarily, it is crucial for maintaining healthy vision, particularly in low-light conditions, by ensuring the proper functioning of the retina and supporting night vision. Additionally, vitamin A plays a pivotal role in promoting a robust immune system, helping the body fight infections and diseases effectively. It contributes to the integrity and health of skin and mucous membranes, acting as a barrier against pathogens and environmental pollutants.Vitamin A and beta-carotene are antioxidants, which may help protect against cancer and improve resistance to certain diseases. They also help form and maintain healthy function of the eyes, hair, teeth, gums, and mucous membranes. In addition, vitamin A is involved in fat metabolism and the production of white blood cells. Vitamin A is a fat-soluble vitamin that comes in two forms: retinol, found in animal tissues, and beta-carotene, found in plants. (Beta-carotene is sometimes called a provitamin because it must be broken down by the body into vitamin A before it acts as a vitamin.) Deficiency : Vitamin A deficiency occurs when the body lacks an adequate amount of vitamin A, a crucial nutrient for various bodily functions. Common symptoms include night blindness, where individuals have difficulty seeing in low-light conditions, and eventually, complete blindness if left untreated. Moreover, vitamin A deficiency weakens the immune system, making individuals more susceptible to infections and illnesses. In children, vitamin A deficiency can lead to stunted growth, delayed development, and increased mortality rates, particularly in developing countries where access to vitamin-rich foods is limited. Pregnant women with a deficiency may face higher risks of complications during childbirth and an increased likelihood of maternal mortality. Vitamin A deficiency often stems from a diet lacking in foods rich in vitamin A, such as liver, eggs, dairy products, and colorful fruits and vegetables. Addressing vitamin A deficiency typically involves dietary changes, supplementation programs, and public health initiatives aimed at improving access to nutrient-rich foods and education on proper nutrition practices.

Eggs: Approximately 520 IU D. Chicken Liver: 12,325 IU Supplements : Over Dosage : Excessive intake of vitamin A, measured in International Units (IU), can lead to a condition known as hypervitaminosis A. This occurs when the body accumulates too much vitamin A over time, causing toxicity. Symptoms of vitamin A toxicity can range from mild to severe and may include nausea, vomiting, dizziness, headache, blurred vision, bone pain, liver damage, and in severe cases, coma or even death. The tolerable upper intake level (UL) for vitamin A, established by health authorities, is around 3,000-10,000 IU per day for adults, varying based on age, gender, and other factors. However, chronic consumption of vitamin A supplements exceeding these levels or excessive consumption of animal liver, which is exceptionally high in vitamin A, can increase the risk of toxicity. It’s essential to be cautious with vitamin A supplementation and to consult healthcare professionals before taking high-dose supplements, especially for pregnant women, as excessive vitamin A intake during pregnancy can harm the developing fetus. Conclusion : So, the best choice is to eat a well-balanced diet and get these nutrients from food sources.
