1. Strengthens the Immune System
While it’s not clear whether megadoses of vitamin C work to prevent or treat a cold, researchers do know that it does boost your immune system and protect against infection and other diseases. It has been shown to shorten the duration of a common cold and enhances phagocytosis by leukocytes, or white blood cells, to destroy invading microorganisms.
In addition, it enhances the production of cytokines and interferons, which are immune response molecules that kill invading bacteria and viruses. It also makes bacterial membranes more absorbable to some antibiotics.
2. Prevents Colds and Flu
Linus Pauling drew much attention to vitamin C when he suggested that it could prevent and treat the common cold, but subsequent placebo-controlled trials have failed to confirm his claims. Research does show that consuming lots of fruits and vegetables does improve the blood levels of vitamin C, but this doesn’t reduce the risk of getting a cold.
The massive doses of vitamin C found in popular OTC products like Airborne or Emergen-C won’t help prevent you from catching a cold, either. But loading up on it once you start to sniffle might make your cold come and go faster, Gigi El-Bayoumi, M.D., associate professor of medicine at the George Washington University School of Medicine and Health Sciences, tells WebMD. This is likely due to the fact that it can lower your oxidative stress, スーパーカマグラ Help immune response to infection and might even make your symptoms less severe.
3. Prevents Heart Disease
Most people get enough vitamin C through their diet, though malnourishment, smoking, alcohol use disorder, poor hygiene, stress and certain health conditions can lead to low vitamin C levels. Taking vitamin C supplements can help ensure that you get enough vitamin C, but it is important to talk with your doctor first.
A registered dietitian can help you determine whether vitamin C supplements are appropriate for your health and what dosages will be safe to take. Be sure to look for the recommended daily allowance on the label and be careful not to exceed the tolerable upper limit, or TUL.
4. Strengthens the Bones
Taking too much vitamin C can have negative effects. For example, high doses of vitamin C can increase the likelihood of diarrhea and kidney stones in some people. It can also interfere with some cancer treatments by increasing oxalate levels in the urine. Those with chronic kidney disease should talk to their doctor before taking a vitamin C supplement.
Although more studies are needed to show whether vitamin C can prevent the common cold, reduce cancer risk or lower blood pressure, researchers have found that it does boost immunity and help your immune system function better. It also helps lower oxidative stress, lower gout risk and improve iron absorption. シアリス 通販 help reduce the risk of heart disease and eye diseases, such as cataracts and age-related macular degeneration.
5. Strengthens the Skin
To reap the benefits of vitamin C, you should consume it in its natural form, ascorbic acid, or apply it topically on the skin. However, you should be careful when choosing a topical vitamin C product. It is important to find one that has undergone extensive research and has been formulated for enhanced stability and skin penetration, says Herrmann.
Moreover, you should only use products that are safe for your skin type and should not overuse them. In addition, you should always apply a sunscreen with broad-spectrum protection when using vitamin C on the skin.
6. Prevents Cancer
Scientists are testing whether giving patients high-dose vitamin C injections alongside their cancer treatments might help fight certain kinds of tumors. These injections, called megadose therapy, deliver 75 to 125 grams of vitamin C straight into the bloodstream, much higher than what you could get from oral supplements.
It’s too early to tell if this approach will be useful, and it could have side effects. For example, taking too much vitamin C might cause iron overload in people with a condition known as hemochromatosis (see the article on Iron). And it may interfere with some medications. Before you start taking any dietary supplement, talk to a Registered Dietitian or your doctor about your health goals and needs.
