Although most people associate vitamin C with citrus fruits, it's present in various vegetables and fruit. These include broccoli, red peppers, spinach, cabbage, kiwi fruit, and strawberries.
This water-soluble vitamin helps boost immunity, protect against disease, and promote healthy skin. It also helps prevent allergies and promotes wound healing. You can also use Fildena 100 if your doctor prescribes it for you.
Antioxidant
Ascorbic acid, vitamin C, is a water-soluble vitamin found naturally in citrus fruits and vegetables. It is a potent antioxidant essential for several body processes, including wound healing, collagen production, and the proper functioning of immune cells.
It can also reduce the risk of heart disease, a leading cause of death in America. It helps lower high blood pressure, heart attack, and stroke risk factors.
Vitamin C is an essential nutrient in small amounts to stay healthy. It supports the health of our skin, bones and connective tissue, blood vessels, and gums. It also promotes wound healing and helps our bodies absorb iron.
In addition to helping maintain the strength of our immune systems, vitamin C has been shown to decrease cold and flu symptoms. It can help prevent angina by limiting the number of free radicals in our blood, which contribute to plaque buildup and fatty deposits in our arteries.
Additionally, it may protect our eyes by preventing the harmful effects of exercise-induced oxidative stress on retinal cells. It also helps prevent preeclampsia, which causes a surge in blood pressure during pregnancy.
When taken regularly, it can increase the number of immune cells called T-cells. T-cells are crucial in reducing the risk of infections and other diseases.
As an antioxidant, it can scavenge the damaging reactive oxygen species (ROS) in our bodies that cause inflammation and other immune system problems. This process deactivates ROS and protects our white blood cells, allowing them to keep fighting off bacteria and viruses.
Finally, it can improve skin elasticity and firmness by increasing collagen synthesis. Collagen is an important part of the connective tissue that makes up our skin, tendons, ligaments, and bones.
It also has been shown to enhance the absorption of non-heme iron, which our bodies can't absorb without supplementation. It is also a key nutrient in wound healing and has been shown to shorten healing time.
Immune System
Besides being an antioxidant, vitamin C is also important for immune health. It helps fight infections, improves wound healing, and strengthens the body's defenses against free radicals.
Although we can't make this vitamin in our bodies, getting plenty of it through diet and supplements is essential. It can help prevent various ailments, including chronic diseases such as heart disease and cancer.
It's also necessary to form collagen, a protein that helps repair wounds and maintain skin elasticity. A deficiency in this nutrient can weaken the skin barrier, which could result in various problems, such as acne and dermatitis.
There are many ways that vitamin C can help the immune system, but one of its most notable effects is that it reduces the severity and duration of cold and flu symptoms. The nutrient can also stimulate the production of white blood cells, the body's first line of defense against infections.
In addition, vitamin C helps activate phagocytes, immune cells that capture and digest bacteria and viruses. This allows the body to respond quickly to infection by sending the appropriate immune cells to attack the bacteria or virus.
The vitamin also helps protect the body's white blood cells from being damaged by reactive oxygen species, or ROS, released during the immune response. When ROS leak out of the compartments where white blood cells are stored, they can damage the immune system's ability to kill invaders.
Because of this, it's crucial to consume enough vitamin C during cold and flu season and regularly to ensure your immune system remains strong and healthy. This is especially true if you're prone to the flu, as the nutrient can increase the number of white blood cells in your body and boost your body's ability to attack the virus.
However, it's important to note that while supplements may have some benefits in helping the immune system, they will only work if your lifestyle is healthy. For example, if you're a smoker; drink too much alcohol; eat poorly; or are chronically stressed, your immune system will be compromised, and you cannot benefit from supplements. This is why it's crucial to follow a healthy, balanced diet and live an active lifestyle for accessories to be effective.
Cardiovascular Health
Vitamin C has long been considered an important nutrient for cardiovascular health. It helps dissolve arterial plaque and reduces oxidative stress in arteries, lowering cholesterol levels and improving endothelial function. It also boosts immunity by increasing the production of white blood cells and interferon, which help fight off infections.
In addition, it promotes the healthy growth of collagen and connective tissues that make up arteries and organs. These vascular walls must be strong and elastic for blood flow to travel smoothly. Low vitamin C intake is associated with greater arterial deterioration and a higher risk of heart disease, stroke, and death.
Several large cohort studies have demonstrated that individuals with higher plasma concentrations of vitamin C are less likely to have heart disease or develop a cardiovascular event than people with lower levels of this vitamin. For example, the European Prospective Investigation into Cancer and Nutrition (EPIC) study found that men and women with the highest plasma vitamin C concentrations had a 50% lower risk of heart failure, all-cause mortality, and ischemic heart disease than those with the lowest levels of this nutrient.
The same research also showed that participants who took 500 milligrams of vitamin C daily significantly improved their blood vessel tone and reduced endothelin-related vessel constriction, which are good indicators of heart health. These findings suggest that a diet high in antioxidant-rich fruits and vegetables can improve the heart's health.
Another interesting finding is that the amount of vitamin C in your bloodstream is inversely related to your blood pressure. Researchers at the University of California at Berkeley found that participants in the highest one-fourth of the vitamin C blood level distribution had 4.66 mmHg lower systolic and 6.04 mmHg lower diastolic pressure than those in the most inferior half. This is an important dietary factor because hypertension (high blood pressure) greatly increases the risk of heart disease and stroke.

Cancer
Vitamin C is an essential nutrient found naturally in many fruits and vegetables. It can also be synthesized from other nutrients, and the body needs to have adequate levels of this nutrient to function properly.
While this nutrient is not directly toxic to cancer cells, it does indirectly affect the development of certain types of cancers by inhibiting glucose transport in cancer cells and stimulating enzymes that can kill cancer cells. Scientists have shown that this effect is mediated through the oxidation of vitamin C to dehydroascorbate (DHA) in the extracellular space and subsequently inside the cell.
Cancer cells take up the vitamin through glucose transporters such as GLUT1 and are reduced in the cell to DHA. When DHA is oxidized in the extracellular space, it generates ROS that damages DNA. This causes PARP to activate and NAD+ depletion to inhibit glycolysis, resulting in an energy crisis and finally cell death.
Another way that high doses of vitamin C can cause cell damage is by increasing the levels of a protein called p53 in cancer cells. This protein is a tumor suppressor and can be turned on when ROS damages cancer cells. In this case, p53 activates the apoptosome, an enzyme that can kill cancer cells by inducing apoptosis.
Although a large amount of evidence suggests that vitamin C can be effective in preventing and treating cancer, many studies have not been conducted in a controlled, scientific manner. Hence, the medical community remains neutral until such higher-level studies have been completed. Until then, high-dose intravenous (IV) vitamin C therapy is being studied as a therapeutic agent for resectable or metastatic solid tumor malignancies.
This treatment is being administered to patients with colorectal and pancreatic cancers with mutations in the oncogenes KRAS or BRAF. The study is being conducted at Weill Cornell Medicine in New York, and it is being led by Dr. Manish Shah, Director of the Gastrointestinal Oncology Program.
