External signs of aging are obvious -- wrinkles, sagging skin and thick glasses can give your age away. Internal signs of aging may not be so obvious, such as the inability to remember where you put your car keys. There are a few key vitamins that should be added to your daily routine, as they fight both internal and external signs of aging.
Vitamin C is a dominant antioxidant vitamin that fights visible and invisible signs of aging. As you age the elastin fibers and collagen content of the skin decrease. When researchers at Tokyo Metropolitan Institute of Gerontology applied topical vitamin C to aging mice, they found it reversed the damage to collagen and elastin fibers. Published in the May 1, 2009, issue of "Biochemical and Biophysical Research Communications," the researchers conclude that vitamin C fights skin aging by penetrating the skin and renewing collagen and elastin.
Vitamin C also fights internal aging, according to a report in the 2007 issue of "Medical Hypotheses," which states that high levels of vitamin C can prevent aging-related diseases such as heart disease, neural disease and cancer.
Vitamin E is an antioxidant vitamin that works in conjunction with vitamin C. Researchers at Mount Sinai Medical Center report that when vitamin E is used with vitamin C, the aging benefits to skin are increased as the two help rebuild collagen. Vitamin C also helps revive damaged vitamin E.
Vitamin E fights internal aging damage as well, particularly in the brain. A report in the May 22, 2009 edition of "Scientific World Journal" explains that supplementing with vitamin E beginning in middle age, along with exercise, can help prevent the onset of cognitive decline and dementia associated with aging and help prevent Alzheimer's disease.
Vitamin A is another antioxidant vitamin that offers several antiaging benefits. The University of Maryland Medical Center reports that vitamin A is especially helpful in protecting the eyes, as it prevents age-related macular degeneration as well as the development of cataracts. It is also reported to help prevent osteoporosis by protecting bone mass. Vitamin A even has positive effects on the aging brain. UMMC states that vitamin A may improve learning ability and memory, and that those who are diagnosed with Alzheimer's disease have significantly low levels of vitamin A.
Although not considered an antioxidant vitamin, vitamin D delivers significant antiaging benefits. The March 21, 2011 issue of "Maturitas" reports that the aging process is directly associated with low levels of vitamin D which can lead to frailty and cardiovascular events. Authors of the study, from the University of Zaragoza in Spain, believe that vitamin D supplementation should be further studied for its ability to increase longevity and prevent aging-related conditions.
