Vitamin C Infusion
Vitamin C, also known as ascorbic acid, is necessary for the growth, development and repair of all body tissues. It's involved in many body functions, including formation of collagen, absorption of iron, the immune system, wound healing, and the maintenance of cartilage, bones, and teeth.
Vitamin C is one of many antioxidants that can protect against damage caused by harmful molecules called free radicals, as well as toxic chemicals and pollutants like cigarette smoke. Free radicals can build up and contribute to the development of health conditions such as cancer, heart disease, and arthritis.
Vitamin C is not stored in the body (excess amounts are excreted), so overdose is not a concern. But it's still important not to exceed the safe upper limit of 2,000 milligrams a day to avoid stomach upset and diarrhea.
Water-soluble vitamins must be continuously supplied in the diet to maintain healthy levels. Eat vitamin-C-rich fruits and vegetables raw or cook them with minimal water so you don't lose some of the water-soluble vitamins in the cooking water.
Vitamin C is easily absorbed both in food and in pill form, and it can enhance the absorption of iron when the two are eaten together.
How Much Vitamin C Is Enough?
Most of the studies showed that the amount used 500 daily milligrams of vitamin C to achieve health results. That's much higher than the RDA of 75-90 milligrams a day for adults. So unless you can eat plenty of fruits and vegetables, you may need to take a dietary supplement of vitamin C to gain all the benefits. Studies suggests taking 500 milligrams a day, in addition to eating five servings of fruits and vegetables.
Vitamin C is one of the safest and most effective nutrients, experts say. It may not be the cure for the common cold (though it's thought to help prevent more serious complications). But the benefits of vitamin C may include protection against immune system deficiencies, cardiovascular disease, prenatal health problems, eye disease, and even skin wrinkling.
A recent study published in Seminars in Preventive and Alternative Medicine that looked at over 100 studies over 10 years revealed a growing list of benefits of vitamin C.
"Vitamin C has received a great deal of attention, and with good reason. Higher blood levels of vitamin C may be the ideal nutrition marker for overall health," says study researcher Mark Moyad, MD, MPH, of the University of Michigan. "The more we study vitamin C, the better our understanding of how diverse it is in protecting our health, from cardiovascular, cancer, stroke, eye health and immunity to living longer."
Here are all the foods and beverages you need to consume to reach 500 milligrams (mg):
Cantaloupe, 1 cup (8 ounces): 59mg
Orange juice, 1 cup: 97mg
Broccoli, cooked, 1 cup: 74mg
Red cabbage, 1/2 cup: 40mg
Green pepper, 1/2 cup, 60mg
Red pepper, 1/2 cup, 95mg
Kiwi, 1 medium: 70mg
Tomato juice, 1 cup: 45mg.
Benefits of Vitamin C
Stress. "A recent meta-analysis showed vitamin C was beneficial to individuals whose immune system was weakened due to stress, "because vitamin C is one of the nutrients sensitive to stress, and [is] the first nutrient to be depleted in alcoholics, smokers, and obese individuals, it makes it an ideal marker for overall health."
Colds. When it comes to the common cold, vitamin C may not be a cure. But some studies show that it may help prevent more serious complications. "There is good evidence taking vitamin C for colds and flu can reduce the risk of developing further complications, such as pneumonia and lung infections.
Stroke. Although research has been conflicting, one study in the American Journal of Clinical Nutrition found that those with the highest concentrations of vitamin C in their blood were associated with a 42% lower stroke risk than those with the lowest concentrations.
Other studies have suggested that vitamin C may also:
Improve macular degeneration.
Reduce the risk of cancer and cardiovascular disease
