Does Vitamin C Work? (Cont.)

 
Does Vitamin C Work for Eye Health?
Vitamin C (in combination with zinc, beta-carotene, and vitamin E, the so-called "AREDS" vitamin combination) has been shown to slow the worsening of age-related macular degeneration. There is no real reason to suspect that vitamin C alone would also be beneficial for age-related macular degeneration. The same vitamin combination has not been shown to be effective for preventing cataracts.
 
Does Vitamin C Work for Hearth Health?
People have claimed that vitamin C may be helpful for the following heart uses:
 
There is not enough evidence to know for sure if vitamin C has any benefit for preventing heart disease or heart attacks. Some studies have shown benefit (especially in people deficient in vitamin C), while other studies have shown no benefit. At this time, the American Heart Association (AHA) does not support the use of vitamin C for reducing the risk of heart disease.
 
While some studies suggest that vitamin C may slow the progression of atherosclerosis (hardening of the arteries), other studies have failed to confirm these findings. More research is necessary to know for sure if vitamin C can help with atherosclerosis. Vitamin C does not seem to lower cholesterol. While some studies have shown that vitamin C (when added to high blood pressure medications) can help lower blood pressure, there is no evidence that vitamin C alone also has this effect.
 
Does Vitamin C Work for Skin Health?
Vitamin C skin creams and serums have been wildly popular as ways to reverse skin aging, such as wrinkles. There is actually a little evidence that such vitamin C products may actually improve the appearance of wrinkles or other signs of skin aging.
