Vitamin C

What are the benefits of vitamin C on the body?

Vitamin C, also known as ascorbic acid, provides many benefits for the human body, including:

  1. Antioxidant protection: Vitamin C acts as an antioxidant, protecting cells from damage caused by harmful molecules called free radicals.
  2. Collagen production: Vitamin C is essential for the production of collagen, a protein that helps to maintain skin, bone, and joint health.
  3. Immune system support: Vitamin C helps to support the immune system by stimulating the production and function of white blood cells.
  4. Iron absorption: Vitamin C helps the body absorb iron from plant-based foods.
  5. Wound healing: Vitamin C is involved in the healing process of wounds and tissue repair.
  6. Mood regulation: Vitamin C has been linked to improved mood and reduced stress.

The antioxidant vitamin C can neutralize free radicals in the body, which also helps prevent oxidative stress. Free radicals are molecules prone to instability, which can cause damage to cells and contribute to the development of chronic diseases and the aging process.

When free radical interacts with a biological molecule, it has the potential to rob that molecule of an electron, which in turn can cause the molecule to become unstable and contribute to oxidative stress. Vitamin C gives up one of its electrons to a free radical to perform its role as an antioxidant. This renders the radical harmless and stops it from wreaking havoc on the body’s cellular structure.

The body’s stores of other antioxidants, such as vitamin E, can be replenished when vitamin C is present, in addition to its ability to counteract the effects of free radicals. This helps to maintain a balance of antioxidants in the body, which is crucial for overall health and well-being since it prevents free radical damage.

Vitamin C helps the body absorb iron from plant-based foods, also known as “non-heme iron.” Non-heme iron isn’t as easily absorbed by the body as heme iron, which is found in animal products. Vitamin C helps the body take in non-heme iron by changing it into a form that is easier for the body to use.

When iron-rich plant-based foods are eaten with vitamin C, the body can absorb more iron. This is important because iron is needed for many things in the body, like making hemoglobin, which carries oxygen in the blood, and for the growth and repair of tissues.

It’s worth noting that eating foods high in iron and foods high in vitamin C together can help the body absorb iron much better. Some good food combinations are:

Spinach and strawberries
Broccoli and tomatoes
Lentils and bell peppers

Vitamin C has been shown to impact mood and emotional well-being. Here’s how:

  1. Stress reduction: Vitamin C helps reduce stress’s effects on the body. Chronic stress can increase levels of the stress hormone cortisol, which can negatively impact mood and emotional well-being. Vitamin C helps to reduce cortisol levels and improve the body’s ability to cope with stress.
  2. Serotonin synthesis: Vitamin C synthesizes serotonin, a neurotransmitter that regulates mood, sleep, and appetite. Vitamin C can help regulate mood and improve emotional well-being by supporting the synthesis of serotonin.
  3. Antioxidant protection: Vitamin C acts as an antioxidant, neutralizing free radicals in the body and preventing oxidative stress. Oxidative stress has been linked to depression and other mental health problems, and vitamin C can help to reduce oxidative stress and improve mood.
  4. Inflammation reduction: Vitamin C can help reduce inflammation in the body, which has been linked to depression and other mental health problems. By reducing inflammation, vitamin C can improve mood and emotional well-being.

Vitamin C is a water-soluble vitamin, meaning that any excess amount is not stored in the body and must be obtained regularly through diet or supplements.

What is the daily recommended intake of Vitamin C?

The recommended daily intake (RDI) of Vitamin C for adults varies based on factors such as age, sex, pregnancy, or breastfeeding, as well as lifestyle and habits. Here are the RDIs for various categories of adults:

  • Men: 90 mg/day – 2000 mg max
  • Women: 75 mg/day – 2000 mg max
  • Pregnant women: 85 mg/day – 2000 mg max
  • Breastfeeding women: 120 mg/day -2000mg max
Smokers: 125 mg/day (35 mg/day more than non-smokers)

Smokers need more Vitamin C for several reasons:

  1. Smoking increases the production of free radicals, which can damage cells and tissues. Vitamin C is an antioxidant that helps to protect against free radical damage.
  2. Smoking also depletes the levels of Vitamin C in the body.
  3. Vitamin C helps to protect the lung tissue from damage caused by smoking and may help to reduce the risk of lung cancer and other respiratory problems.
  4. Smoking also impairs the immune system, and Vitamin C is essential for a healthy immune system.

Therefore, smokers may need more Vitamin C to support their overall health and reduce the risk of damage caused by smoking. However, it is essential to consult a healthcare professional before taking high doses of Vitamin C supplements, as individual needs and tolerance may vary.

Alcohol consumers: Add 35 mg/day to their RDI to account for the increased oxidative stress from alcohol.

When you drink alcohol, your body needs more Vitamin C for several reasons:

  1. Alcohol is metabolized in the liver and produces toxins and free radicals that can damage liver cells. Vitamin C is an antioxidant that helps to protect against free radical damage.
  2. Alcohol also depletes the levels of several nutrients, including Vitamin C, in the body.
  3. Vitamin C is involved in the detoxification process of alcohol in the liver and helps to prevent liver damage and improve liver function.
  4. Alcohol can also impair the immune system, and Vitamin C is essential for a healthy immune system.

Therefore, people who drink alcohol may need more Vitamin C to support their liver health, reduce the risk of liver damage, and maintain optimal health. However, it is essential to consult a healthcare professional before taking high doses of Vitamin C supplements, as individual needs and tolerance may vary.

Adults with high physical activity levels: Add an additional 35 mg/day to their RDI.

When you have high levels of physical activity, your body needs more Vitamin C for several reasons:

  1. Physical activity increases the production of free radicals, which can damage cells and tissues. Vitamin C is an antioxidant that helps to protect against free radical damage.
  2. Vitamin C produces collagen, a protein essential for forming and repairing connective tissue, including muscles, tendons, and ligaments.
  3. During physical activity, Vitamin C helps to reduce the levels of certain hormones that contribute to muscle fatigue and soreness.
  4. Vitamin C is also involved in producing neurotransmitters, which are chemicals that help regulate muscle function and control movement.

Therefore, people who engage in high levels of physical activity may need more Vitamin C to support their active lifestyle and maintain optimal health. However, it is important to consult a healthcare professional before taking high doses of vitamin C supplements, as individual needs and tolerance may vary.

What are the consequences of having too much Vitamin C?

While Vitamin C is essential for good health, excessive consumption can lead to adverse effects. The recommended maximum daily intake of Vitamin C is 2,000 milligrams per day for adults. Consuming more than this amount may lead to the following consequences:

  1. Diarrhea: High doses of Vitamin C can cause diarrhea as the body eliminates the excess.
  2. Nausea and abdominal cramps: High doses of Vitamin C can cause stomach discomfort and nausea.
  3. Kidney stones: Long-term consumption of very high doses of Vitamin C can increase the risk of developing kidney stones in some people.
  4. Interactions with medications: High doses of Vitamin C can interact with certain medications, including blood thinners, and affect their effectiveness.
  5. Oxidation: While Vitamin C acts as an antioxidant in average amounts, consuming excessive amounts can lead to oxidative stress and increase the production of harmful free radicals.

Learn more about how too much vitamin C can cause kidney stones.

When you get too much vitamin C, your body turns it into oxalate. Oxalate is a natural chemical that is found in foods like nuts, fruits, and leafy green vegetables. In the body, oxalate can combine with calcium to form calcium oxalate, a compound that can precipitate and form crystals, leading to kidney stone formation.

High levels of oxalate in the urine can be caused by too much vitamin C, especially from supplements. This makes it more likely for people who are prone to calcium oxalate kidney stones to get them.

Importantly, most people can safely eat the amounts of vitamin C that are part of a normal diet without getting sick. But taking more than 2,000 milligrams of vitamin C per day for a long time can increase the risk of kidney stones in people who are already at risk.

Learn more about how too much vitamin C can interact with medications.

High doses of Vitamin C can interact with certain medications, causing either increased or decreased medication efficacy or potential side effects. Some medications that Vitamin C may interact with include:

  1. Warfarin (Coumadin) – Vitamin C can interfere with the blood thinning effects of warfarin, potentially increasing the risk of blood clots.
  2. Chemotherapy drugs – Vitamin C can enhance the effectiveness of some chemotherapy drugs and reduce their toxicity, but it can also interfere with the action of other chemotherapy drugs.
  3. Nonsteroidal anti-inflammatory drugs (NSAIDs) – Vitamin C can interfere with the absorption and effectiveness of NSAIDs, such as ibuprofen and aspirin.
  4. HMG-CoA reductase inhibitors (statins) – Vitamin C can increase the risk of muscle damage in people taking statins, a type of cholesterol-lowering medication.
  5. Estrogens – Vitamin C can interfere with the effectiveness of estrogen-containing medications.

Additional Questions

What does your body do with access amount of vitamin C?

Your body has a limited ability to absorb and store vitamin C, and excess amounts of vitamin C are generally excreted in the urine. Because vitamin C is a water-soluble vitamin, your body can flush out any excess amounts it doesn’t need.

How much-limited vitamin C can the body store, and where is it stored?

The body can store limited amounts of vitamin C and does not have a long-term storage mechanism for this water-soluble vitamin. Vitamin C is primarily stored in the liver and other tissues, but the amount stored is limited. The body can store about 70-100 milligrams of vitamin C, equivalent to about 1-2 weeks’ worth of the recommended daily intake.

Because the body’s stores of vitamin C are limited, it’s important to consume enough of this vitamin regularly to meet the body’s needs. Vitamin C is not synthesized by the body, so it must be obtained through diet or supplements.

What other vitamins or nutrients work in unison with vitamin C?

There are several vitamins and nutrients that work well with vitamin C:

  1. Vitamin E: Vitamin E is a fat-soluble vitamin that works as an antioxidant in the body. It helps to protect cell membranes from damage caused by free radicals. Vitamin C and E work together to enhance each other’s antioxidant effects.
  2. Zinc: Zinc is a mineral that plays a crucial role in immune function and wound healing. Vitamin C can enhance zinc absorption in the body and may help improve zinc levels in deficient people.
  3. Vitamin D: Vitamin D is essential for bone health and immune function. Vitamin C may help improve the absorption of vitamin D in the body.
  4. Iron: Iron is necessary to form red blood cells and transport oxygen throughout the body. Vitamin C can enhance the absorption of non-heme iron (found in plant-based foods) in the body.
  5. Selenium: Selenium is a mineral that plays a role in thyroid function and immune system health. Vitamin C may help improve the absorption of selenium in the body.

Is it possible your body can not break down Vitamin C?

Yes, some people may have difficulty breaking down Vitamin C. This is due to a genetic condition known as hereditary hemochromatosis, which affects the body’s ability to absorb and process iron. People with this condition can also have difficulty absorbing Vitamin C, leading to a deficiency if not appropriately managed.

What are the signs your body is not breaking down Vitamin C?

If your body breaks down Vitamin C properly, you may experience fatigue, joint and muscle pain, easy bruising, and a weak immune system. But these symptoms can also be caused by several other health problems, so you should see a doctor if you have any strange symptoms. A doctor may perform blood tests to determine if you have a Vitamin C deficiency and to check for other possible causes of your symptoms. Additionally, genetic testing may be done to determine if you have hereditary hemochromatosis, which can cause difficulty absorbing Vitamin C.

In conclusion

Vitamin C is an essential nutrient crucial for human health and well-being. It is involved in many functions within the body and is vital for skin health, eye health, and immune system function. Consuming a diet rich in Vitamin C is the best way to ensure that you get enough of this important nutrient, but supplements are available for those unable to get enough through diet alone. It is important to consume Vitamin C in moderation and not to exceed the recommended daily intake, as overconsumption can lead to adverse effects.
