How vitamin c supports a healthy immune system

Vitamin C or ascorbic acid is a water-soluble vitamin known for its role in supporting a healthy immune system. Because our body cannot make vitamin C, it must come from the foods you eat every day.

Research has shown that vitamin C is essential for the growth and repair of tissues throughout the body. Vitamin C helps heal wounds and repair and maintain healthy bones, teeth, skin and cartilage - the hard tissue that coats bones.  As an antioxidant, vitamin C fights free radicals in the body, which may help prevent or delay certain cancers and heart disease and promote healthy aging. Vitamin C in food also appears to reduce the risk of cartilage loss in people with osteoarthritis.

While it may not keep you cold, there is some evidence that high doses of vitamin C may shorten the duration of cold symptoms by 1 to 1 1/2 days in some people. 

Sources of vitamin c supplement are plentiful, far beyond the ever-popular orange or orange juice

Many fruits and vegetables provide this important vitamin. Sources of vitamin C include citrus fruits, tomatoes, potatoes, strawberries, green and red bell peppers, broccoli, Brussels sprouts, and kiwi, among others. You can enjoy these raw or cooked foods, but it's important to note that fruits and vegetables lose vitamin C when heated or stored for long periods of time. For maximum nutrition, eat as soon as possible after shopping, and consider steaming or microwaving vegetables for short periods of time to limit nutrient loss.

Vegetarians may especially want to know that vitamin C helps the body better absorb non-heme iron—iron from plant foods like beans, spinach, and quinoa. To get this benefit, combine vitamin C-rich foods with iron-rich plant foods in the same meal. For example, combine black beans with salsa, or make a delicious spinach salad with strawberries and oranges.

You need take some Vitamin C dietary supplement if you eat a little or little vegetables in daily diet, or you're prone to vitamin C deficiency if you don't eat fresh fruits and vegetables for two or three months.

Vitamin c tablets should be your good choice, there are 3 kinds of dose for you

Vitamin C 500 mg controlled release tablet, 60 tablet per bottle, small tablets are easy to swallow.

Vitamin C 1000 mg sustained release tablet, 60 tablet per bottle, take 1 tablet each day and give you nutrition of the whole day.

Vitamin C 1500 mg extended release tablet, 60 tablet one bottle, take 1 tablet in a day,just need 1 bottle for 2 month!

Time-release tablets use a special outer coating controlled release technology to release small amounts of the Vitamin C into a person's system between 12 to 24 hour.each tablet is designed with a special coating that releases nothing until it reaches the stomach. Timed release is also referred to as sustained release, extended release, or controlled release. These tend to come in tablet form and are simply made to be more potent but dissolve slowly.Vitamin C timed release tablets are better than instant-release ones.

How Vitamin C supports a healthy immune system? We need discuss it from the health benefits of Vitamin C.

The health benefits of vitamin c supplement are explained in detail below

1. Prevent scurvy

Scurvy is caused by insufficient or deficient intake of ascorbic acid. The symptoms of scurvy are weakening of connective tissue, including collagen, bones, and blood vessels. Vitamin C is a powerful antioxidant that is required to boost collagen production.

2. Treat the common cold

Ascorbic acid strengthens our body's immune system, which protects us from colds and coughs. However, starting a vitamin C supplement when you have a cold may be less helpful than adding it regularly to your diet.

3. Reduce high blood pressure

People with high blood pressure are at high risk for cardiovascular disease. According to a 2012 study published in the American Journal of Clinical Nutrition, vitamin C intake can help lower your body's blood pressure in the short term.

4. Antioxidant as vasodilator

In cases of atherosclerosis, congestive heart failure, high cholesterol, angina pectoris and hypertension, vitamin C treatment is effective in causing proper dilation of blood vessels. A 2016 report published in the International Journal of Molecular Science conducted an epidemiological study of vitamin C to investigate its potential role in cardiovascular disease. Supplementation with this vitamin was found to improve blood vessel dilation and protect cardiovascular health.

5. Prevent lead poisoning

A 1999 study published in the JAMA found that lower levels of vitamin C in the blood were associated with higher levels of lead. A recent study found that "a daily supplement of 500 mg of vitamin C for 1 month is sufficient to suppress the effects of free radicals caused by lead poisoning." This suggests that regular intake of ascorbic acid may prevent elevated levels of lead in the body. 

6. Reduce cataract risk

Cataracts are one of the most common vision problems. Decreased levels of vitamin C in the lens of the human eye are more common when cataracts are present. Excessive intake of ascorbic acid can increase the blood supply to the eye area of the body. According to the American Optometric Association, when vitamin C is consumed along with other essential nutrients, it can slow the progression of age-related macular degeneration (AMD) and vision loss.

7. Improve mood

Vitamin C plays a key role in the production of neurotransmitters such as norepinephrine. They affect a person's mood and are essential for the proper functioning of the brain. A 2013 study showed that short-term treatment of vitamin C improved mood and reduced psychological distress in acutely hospitalized patients with a high incidence of vitamin C deficiency.

8. Boost immunity

Immunity is another great benefit of this vitamin. Vitamin C is widely known for its contribution to the immune system and stimulation of the white blood vessels in the body. A healthier immune system can better protect against infection and disease.

9. Repair wounds

Vitamin C helps repair wounds. It promotes the growth of connective tissue, thereby speeding up the process of wound healing.

10. Manage diabetes

According to a report published in the Indian Journal of Medical Research, results suggest that a daily intake of 1,000 mg of supplemental vitamin C can help reduce blood sugar levels in people with type 2 diabetes, thereby reducing the risk of complications.

11. Prevent heart disease

Adequate amounts of ascorbic acid are essential to protect blood vessels from the damage that free radicals can cause. This may be the main cause of a heart disease called atherosclerosis. Vitamin C acts as a medicine to prevent this heart disease as well as a variety of other heart problems.

While vitamin C is readily present in several fruits and vegetables, this nutrient is also available as a supplement. If you choose the latter, consider consulting with your healthcare provider about how to use it to best benefit your health.
