What Is Vitamin C?

Vitamin C is a powerful antioxidant vitamin that is considered essential. An essential vitamin is one that must be consumed through diet. Vitamin C foods include colorful fruits and vegetables, such as strawberries, cantaloupe, spinach, peppers and tomatoes. Citrus fruits are also a fantastic source of vitamin C such as oranges, lemons, limes and grapefruit. Although there are many dietary sources of vitamin C, it is easily destroyed through heating and freezing. On top of that, fruits and vegetables grown today are grown in nutrient-depleted soil, resulting in a lower nutrient content.

Vitamin C supplements help to ensure that you get enough vitamin C in your diet. For reasons stated above, even people consuming healthy amounts of fruits and vegetables daily may need a good vitamin C supplement. They are available in tablets, chewables, liquids, effervescents, powdered crystallines and vitamin C pills.

Benefits of Vitamin C

The strength of your immune system can be affected by your diet, lifestyle and stress levels. This means that you have the ability to strengthen or weaken your immune system. With that power comes responsibility!

Vitamin C is a very important nutrient that plays a key role in many operations in our bodies. It’s important for the immune system, cell repair, wound healing, bone strength, and more. Some of the most important vitamin C benefits include:

  • Skin: Vitamin C can help to improve skin health, reduce the appearance of wrinkles, and generally slow the visual aging process. This effect has been observed with supplemental oral vitamin C, as well as topical creams.
  • Immunity: Vitamin C can help to strengthen the immune system by improving resistance to certain pathogens. In otherwise healthy individuals, a higher intake of vitamin C may help to slightly lower the duration and severity of the common cold, but the evidence is mixed as to whether or not it can actually help prevent the common cold’s occurrence.
  • Mineral Absorption: The body needs tons of nutrients and minerals like iron and calcium in order to stay healthy. Vitamin C plays a role in the absorption of some of these minerals, particularly in regard to iron. Thus, getting more vitamin C may help to improve your body’s ability to absorb and use iron and other minerals, which can have a variety of positive effects on your health.
  • Antioxidant: Vitamin C is an antioxidant, a class of molecules that can help to fight free radicals in the body and reduce the cell damage that they can cause. Because oxidation and cell damage is thought to contribute to many serious health concerns including cancer, it’s possible that antioxidants such as vitamin C may help to reduce the risk of many diseases, and help to keep the body healthy in general.
  • Stress: Vitamin C can help to reduce the physical and psychological effects of stress on the body. A recent German study found that those given vitamin C before being exposed to a stressful situation remained calmer, and various stress markers including the stress hormone cortisol and blood pressure were notably lower than participants who were not given the vitamin.
  • Overall Health: Vitamin C is involved in a huge number of processes within the body, and it can greatly contribute to overall health. It’s important for absorption of iron, formation of collagen, wound healing, the maintenance of bones, teeth and cartilage, and much more. Although most people eating a balanced diet will get enough vitamin C from food, some groups are more prone to not getting enough.

Vitamin C is one of the most popular supplements, and for good reason. Insufficient vitamin C can lead to several issues, while on the other hand it is actually impossible to get too much of it, as your body simply excretes the excess.

The most effective vitamin C supplements have powerful immune boosting benefits. They also help to provide additional antioxidants in your diet. As a powerful antioxidant, vitamin C has the ability to help the aging process and help improve the function of all of your organs and bodily systems.

Who Can Benefit from Vitamin C?

  • Those with Weakened Immune Systems – A weakened immune system is a weakened defense system. It results in higher risk of sickness, infection and health problems. Your immune system can be weakened by excess sugar consumption, stress, lack of sufficient fluid intake and being overweight. Some people have a more serious condition called an immunodeficiency disorder, which may be present at birth or develop over time. Taking a top vitamin C supplement can boost your immune system and keep you healthy, helping to prevent a state of weakened immunity.
  • Those with Allergies – An effective vitamin C supplement can help to regulate your immune system’s response to potential threats. This is particularly beneficial to those who suffer from allergies. Allergic reactions occur when the immune system mistakes a safe substance for a harmful substance, resulting in an an overreaction to it. Symptoms may include inflammation, swelling, skin rash, nausea, diarrhea, runny nose and anaphylaxis in severe cases. Vitamin C helps reduce inflammation and support the immune system, which can help regulate the symptoms of allergies. It also works to reduce the release of histamine, which is a substance that causes allergic inflammatory reactions.
  • Those Dealing with Stress – Cortisol is known as the stress hormone. It is the damaging hormone that is released when stress triggers it, causing harm to numerous functions of the body. The side effects of elevated cortisol levels include weakened immune function, reduced bone density, weight gain, and elevated blood pressure and cholesterol. It can also interfere with your ability to learn and store memory. Taking a strong vitamin C supplement can help to reduce the physical and psychological effects of stress, improving your overall health and quality of life. This is according to both animal and human studies.
  • Travelers – Traveling exposes your body to numerous new stressors, viruses and bacteria that can weaken your immune system. This can be due to changes your sleeping schedule and your diet, altered environments and introductions to new people. It can also be due to traveling in a cramped plane, where the air is being shared by many different people and disease-causing bacteria can survive for up to a week on armrests, seats and tray tables. A top vitamin C supplement can help prevent illness while traveling.
  • Aging Adults – Vitamin C is a powerful antioxidant that has beneficial anti-aging properties. It has been shown to decrease oxidative stress in your cells, and it helps to prevent wrinkles and dullness of the skin. It also helps to reduce the stress hormone cortisol, which can wreak havoc on your body over the years. By boosting your immune system, it helps to prevent damaging illnesses, and it also supports your cardiovascular health! This means that not only does it help to prevent illness, it can also help to prevent heart disease. As an added bonus, a good vitamin C supplement can help to improve protein absorption. As you age, your ability to digest protein and utilize it properly decreases. Overall, a powerful vitamin C supplement is a great addition to an aging adult’s diet.
  • Those At risk for Arthritis – The best vitamin C supplements help to regulate the immune system, reduce inflammation and support the health of connective tissues and production of collagen. All of these benefits are great for those at risk for rheumatoid arthritis, which is an autoimmune disease that is caused by the immune system attacking joints and causing pain, stiffness and inflammation. It can also help to maintain the health of your joints, helping to prevent osteoarthritis (arthritis caused by joint wear and tear.) This means that taking one of the best vitamin C supplements can help to prevent both major forms of arthritis from developing.
  • Athletes – The best vitamin C supplements can help to aid in athletic recovery. This is because vitamin C is an important nutrient for wound healing, and studies have shown that taking top vitamin C supplements with dosages above the recommended daily allowance improves speed of recovery. It also aids in protein metabolism, which improves protein absorption and utilization. Men who take a good vitamin C supplement are also supporting healthy testosterone levels by lowering levels of cortisol: the more cortisol you have, the less testosterone you have.

Are There Any Side Effects?

Because vitamin C is water soluble, it is well tolerated even in larger doses. However, some people may experience side effects such as heartburn, stomach cramps, headaches, nausea etc. Talk to a doctor before giving vitamin C to a child, or taking more than 1000 mg daily.

How to Take Vitamin C

Vitamin C is water soluble, so it does not have to be taken with food, but many supplements advise that you take it with a meal. It is available in both natural and synthetic forms in tablets, chewables, vitamin C pills, effervescents, etc. Depending on the form, it can be taken in split doses two to three times per day or a single dose.

Dosage instructions will be found on the product packaging. It’s nearly impossible to “overdose” on vitamin C, however, because the vitamin is water soluble and your body will simply excrete the excess vitamin C if you take too much. Side effects are rare, even at larger-than-recommended doses.
