    Most of us know that vitamin C has many benefits such as helping ward off the common cold. But this essential nutrient found in many fruits and vegetables has another little-known function: It can help slow the progress of cataracts, the most common cause of vision loss in adults over 40.

    A study confirmed what many ophthalmologists and eye surgeons already know: A healthy diet rich in vitamin C can help replenish the loss of ascorbic acid in the natural lenses of the human eye. Ascorbic acid is the chemical name for vitamin C. The fluid inside the eye is normally high in vitamin C, which helps prevent oxidation that leads to clouding of the eye lens from cataracts.

    Cataracts affect more than 22 million Americans age 40 and older. Moreover, as the U.S. population ages, more than 30 million Americans are expected to have cataracts by the year 2020. Everyone should probably be eating a diet containing vitamin C anyway. This study confirms that vitamin C helps slow down the progression of cataracts. They used twins in the study, and about 2,000 people were followed over 10 years. The results were very encouraging.

    Vitamin C may help treat a cold by lessening the severity of the symptoms and shortening the duration. The trick is, you have to take vitamin C regularly. If you wait until you feel a cold coming on, it won't help you. To get the benefits of vitamin C, take 1 to 3 grams every day, but no more: Too much C can cause side effects.

    Because vitamin C can interact with other medications, you should discuss any other medications, vitamins, or supplements that you are taking with your doctor prior to taking vitamin C. You should consult your doctor about your vitamin C dosage amount as well, because excessive amounts of vitamin C can cause negative effects within your body. If you have ever had allergic reactions to vitamin C, you should not take it and consult your doctor if your levels are low for additional options. Finally, if you have had kidney or liver problems, heart disease, anemia, diabetes, enzyme problems, or are pregnant or breastfeeding, you should consult your doctor before beginning a vitamin C regimen.

    Generally, vitamin C that is gotten from food intake is safe for pregnant or breastfeeding women. However, research is unclear about the safety of more than the recommended amounts of vitamin C in pregnant or breastfeeding women. Vitamin C is excreted through breast milk. However, not enough research has been done to determine if it is beneficial or not to the infant. You should tell your doctor if you are pregnant, breastfeeding, or planning to become pregnant and you are contemplating taking a regimen of vitamin C tablets. Your doctor can help determine the best dosage for your situation.

    One study suggests that taking a vitamin C supplement may help keep blood pressure under control. In the study, participants with high blood pressure took 500 milligrams of vitamin C daily for eight weeks, and noted a reduction in the systolic (top) number.

    A healthy blood pressure is now considered to be a systolic below 120, and a diastolic (bottom) number lower than 80. Many Americans have hypertension or elevated blood pressure, and the concern is that most may not know their blood pressure is high because symptoms are often silent. That’s why it has been named the “silent epidemic.” Measures to control blood pressure include eating a healthy well-balanced diet rich in fruits and vegetables and lower in sodium.

    Always talk with your doctor before starting supplements, especially if you have any health conditions and/or are taking other medications.

    Research is not in agreement about whether vitamin C decreases the severity and duration of the common cold. While some studies show a mild protective effect, others do not. Most studies show vitamin C was no more effective than a placebo at shortening the duration of cold symptoms. However, foods rich in vitamin C (citrus fruits, berries, kiwis, red bell pepper, tomatoes, broccoli, spinach, and guava) are also loaded with other nutrients that can contribute to a nutrient-dense diet which does help support good health.

    Taking 500 milligrams of vitamin C twice a day can boost your immune system (and have a RealAge effect) of making you up to one year younger. You can take it in supplement form, and also get it through foods such as oranges and other citrus fruits, 100 percent natural orange juice, tomatoes, and bell peppers.

    Yes, it can. Deferoxamine and iron supplements are both known to interact with vitamin C supplements. Vitamin C can also interact with aspirin, acetaminophen, fluphenazine, indinavir, levodopa, patches used for smoking cessation, antacids containing aluminum, certain antibiotics, certain barbiturates, blood thinners, birth control pills and hormone replacement therapies. If you take any of these medications or drugs regularly, you should notify your doctor before you begin taking vitamin C.

    Two age-reducing vitamins, if taken together, are C and E. Although these vitamins exert powerful antioxidant activity, they may be producing their benefits through effects that are very different from antioxidation. Taken together, vitamins C and E help keep your cardiovascular system healthy by reducing the amount of harmful buildup on the walls of your arteries. In addition, vitamin C strengthens the immune system, improves both eye and lung function, and helps the body heal. Vitamins C and E, taken in combination, help keep the arteries relaxed and elastic. You can make your RealAge (physiologic age) one year younger by taking 600 milligram (mg) or more (up to 2,000 mg) of vitamin C a day as supplements (in divided doses of no more than 500 mg in any six hours) and 400 international unit (IU) of vitamin E a day, in addition to eating a balanced diet with lots of fresh fruits and vegetables.
