Vitamin E Increases Mice Lifespan
Spanish and Argentinian researchers say vitamin E's antioxidant power helped mice live 40 percent longer than a control group. They also claim it improved the quality of their lives as well as longevity.Although the study cannot be directly compared with effects in humans, it appears to counter the results of a controversial meta-analysis published last year that suggested a higher risk of death for people that took vitamin E supplements.
Scientists from the University of Cadiz in Spain and the University of Buenos Aires used 300 mice bred to age rapidly that normally live for an average 61 weeks. Aged 28 weeks, half of the animals were given daily supplements of vitamin E, equivalent to a dosage of about 1200-2000mg per day in humans.
Although this amount is much higher than the RDA, it has been used without adverse effects in studies on Alzheimer's disease patients.
In the study, the mice given the vitamin E supplements lived an average of 85 weeks without any negative side effects being observed. The maximal lifespan increased 17 per cent to 136 weeks.
Further, the researchers found that vitamin E supplements appeared to improve the ability of mice to perform in neuromuscular tests, thus suggesting that the vitamin improved quality of life.
The vitamin E group was better than the others at crossing a 50 centimetre-high wire tightrope and negotiating a T-shaped maze. As they aged, the differences were even greater, with the mice given regular vitamin E performing up to 45 per cent better at tests.
Writing in the 14 July online issue of the American Journal of Physiology-Regulatory, Integrative and Comparative Physiology, the researchers said the findings supported the free radical theory of ageing put forward by Gerschman and Harman in the 1950s.
For example, this theory was supported by the fact that the mice given vitamin E had lower levels of free radical mediated reactions and oxidative damage in their mitochondria, the energy source of all cells.
Normally in ageing there is an increase in products of oxidation.
The vitamin E supplements were also "able to prevent the decrease in the activities of brain enzymes that are mitochondrial markers of ageing" by substantial levels, said Alberto Boveris, professor at the University of Buenos Aires.
The researchers write that the "mitochondrial content of lipid protein oxidation products, an indication of free-radical mediated reactions and oxidative damage, was increased in the brain and liver of ageing mice, and the effect was partially [and significantly] prevented by vitamin E."
This was shown by measuring the protein carbonyl content of brain mitochondria, which increased 33 per cent to 69 per cent at 52 and 76 weeks from 28 weeks, and this increase was markedly prevented (76 per cent and 65 per cent) by vitamin E supplementation measured at the two age points.
The researchers say that further studies are needed to find the threshold for vitamin E doses that provide beneficial effects in the neurological function in ageing mammals.

Vitamin E Reduces Inflammation: Key to Reducing Heart Disease, Stroke and Other Health Problems
Vitamin E plays a significant role in both reducing inflammation and cleansing the body of damaging free radicals, according to a prominent cardiovascular surgeon speaking today at a health and science writers' workshop on vitamin E and health, held at the New York Academy of Sciences and sponsored by the Council for Responsible Nutrition. However, Americans don't consume enough vitamins and minerals in their diets because of modern methods of food production, so they should consider using supplements to replace the missing nutrients.
Inflammation is the heart of the matter. It's becoming clear that inflammation plays an important causative role in heart disease, Gerald M. Lemole, M.D., told the group. He is W. Samuel Carpenter III Distinguished Chair of Cardiovascular Surgery, Chief of Cardiac Surgery at Christiana Care Health Services, and Professor of Surgery at Thomas Jefferson University. The cardiac surgeon explained that normal inflammation is the body's protective response to toxins, pathogens, irritants, trauma, free radicals, and unrecognized molecules. However, things can go wrong, and groups of inflamed white blood cells may build up, rupture, and trigger a heart attack. The body's response to this is an elevated C-reactive protein (CRP) level, homocysteine level, and fibrinogen-all implicated in worsening heart disease.
In fact, cardiologists now consider an elevated CRP level to be an increasingly important marker for heart disease. He told the group that other risk factors for inflammation are obesity, smoking, genetic predisposition, high stress, and diets rich in highly processed and carbohydrate-rich foods. Chronic inflammation, he said, is linked to periodontal disease, diabetes, Alzheimer's disease, and cancer as well as heart disease. Antioxidants such as vitamin E can ameliorate that risk.
In discussing why nutritional supplementation may be necessary, Dr. Lemole listed several reasons such as environmental stress, nutritional deficiencies in our food supply, inadequacy of the recommended requirements, constitutional variations, and medically induced deficiencies.
He said, We've industrialized farm production, and that's led to serious problems in the micro-nutritional composition of foods.
Growth hormones and antibiotics, which deplete vitamins A and B, are used in over half of commercial livestock. Refinement of sugars, grains, flours, and other food has deprived us of consuming many essential and nutritional ingredients.
Dr. Lemole told the group that the situation is worsening. There are fewer and fewer naturally occurring antioxidants in our food supply. He cautioned, "We know that an inflammatory process can trigger certain diseases. We're aware that age-related immune deficiency is caused by free radicals and that it can be reversed by antioxidants. And unfortunately, we're all too familiar now with the realization that wall of the artery is a living, reactive tissue capable of mounting an inflammatory response. That inflammatory response is heart disease."

Can This Vitamin Slow the Aging Process?
Vitamin E supplements, especially when taken with regular exercise, may prevent or delay the ravaging illnesses so common with aging, including heart disease, cancer, and Alzheimer's, according to research from the University of Florida that was published in the journal Biological Research for Nursing.
This is how it works:
1. Vitamin E knocks out free radicals, which are unstable molecules that can damage healthy cells and lead to the development of some 200 age-related diseases.
2. Exercise boosts antioxidant substances that can combat those damaging free radicals.
3. Put them together and it's a more powerful combination than either one used alone--and it could be the next best thing to the fountain of youth.
The study: The Florida researchers tested the two anti-aging methods on 59 men and women ages 60 to 75. None exercised regularly. They were divided into four groups:
· Group 1: Exercised twice a week for 60 minutes and took an 800 IU vitamin E supplement.
· Group 2: Exercised twice a week for 60 minutes and took a placebo.
· Group 3: Sedentary and took an 800 IU vitamin E supplement.
· Group 4: Sedentary and took a placebo.
The results: All the participants who took vitamin E--whether they exercised or not--saw a significant reduction in free radicals. In addition, exercise provided its own special protection as it increased the amount of antioxidant substances that would fight the free radicals.
So while group 1, which exercised and took the vitamin E supplements, didn't do any better than group 3, which only took the vitamin E and did not exercise, those who were active also lost weight, lowered their blood sugar and blood pressure, and boosted their exercise capacity. That led researchers to conclude that the best approach to battling the ravages of old age is a combination of moderate exercise and vitamin E.
"The results of this study suggest that people who are over 40 can benefit from regular moderate exercise and vitamin E to protect against the destructive properties of free radicals and their effects on our aging bodies," James Jessup, the study's principal investigator, said in the news release announcing the study findings.
How much vitamin E do you need for full protection? After age 40, you need the equivalent of two heads of spinach--every day. So in this case, supplements are best!

Antioxidant Vitamins Can Protect Eyes Better Than Carrots, Harvard Says; Vitamin E Cited
Antioxidant vitamins such as vitamin E may protect the eyes against cataracts and age-related macular degeneration, according to a new special health report from Harvard Medical School.
There's some truth to the belief that "eating carrots is good for the eyes," the Harvard publication said, but noted that diets containing more antioxidant vitamins such as vitamin E and vitamin C "are even better."
The Harvard Health Letter said in its May issue that a recent government study finding that Vitamin E and other vitamins and minerals may slow progression of macular degeneration "was a success."
The study, called the Age-Related Eye Disease Study or AREDS, was conducted by the National Institutes of Health. Doses used in the trial were 400 international units of Vitamin E, 500 milligrams of Vitamin C, 15 milligrams of beta carotene, 80 milligrams of zinc, and two milligrams of copper. The Harvard Health Letter pointed out, however, that the positive results were in people who already had moderate to serious macular degeneration, and that the vitamin-mineral combination hasn't been shown to help "people who had no macular degeneration or only a mild case." The Harvard publication recommended that patients don't take vitamins and minerals for the condition until "an ophthalmologist has examined your eyes and determined that you're a high-risk patient."
More than a quarter of Americans aged 75 or older show some signs of macular degeneration, the Harvard Health Letter said. Severe vision loss can result, "although no one goes totally blind from macular degeneration."

Vitamin E and Blood Pressure
Nutraceutical: Vitamin E
Indication: Blood pressure
Source: International Journal for Vitamin & Nutrition Research, 2002;72:309-314
Research: Researchers asked 70 patients with newly diagnosed mild hypertension to take either 200 IU of vitamin E or placebos daily for 27 weeks. Blood pressure levels before treatment ranged from 140 mmHg to 160 mmHg systolic and 90 mmHg to 100 mmHg diastolic (140/90-160/100).
Results: Overall, patients taking vitamin E supplements had a significant 24% decrease in systolic blood pressure, compared with 1.6% decrease in the placebo group. Diastolic blood pressure declined by 12.5% in the vitamin E group compared with 6% in the placebo group.
Vitamin C & E and Bladder Cancer
Nutraceutical: Vitamin C and E
Indication: Bladder Cancer
Source: Am J Epidemiol December, 2002;156(11):1002-10.
Research: The study authors examined the association between use of individual vitamin C and vitamin E supplements and bladder cancer mortality among 991,522 U.S. adults in the Cancer Prevention Study II (CPS-II) cohort.
CPS-II participants completed a self-administered questionnaire at enrollment in 1982 and were followed regarding mortality through 1998.
Results: During follow-up, 1289 bladder cancer deaths occurred (962 in men and 327 in women). Rate ratios were adjusted for age, sex, cigarette smoking, education and consumption of citrus fruits and vegetables. Regular vitamin C supplement use was not associated with bladder cancer mortality, regardless of duration. Regular vitamin E supplement use for 10 years was associated with a reduced risk of bladder cancer mortality, but regular use of shorter duration was not. Results support the hypothesis that long-duration vitamin E supplement use may reduce the risk of bladder cancer mortality.
Vitamins E, C May Counteract Unhealthy Fast Food
Researchers have found that high intakes of glucose and high-fat, high-calorie fast food meals both cause an increase in the inflammatory components of the blood.
They also found that an extra dose of antioxidant vitamins E and C can block this inflammatory response in the bloodstream.
"A meal high in calories and fat caused an increase in inflammatory markers that lasted three to four hours," said Dr. Paresh Dandona, a senior endocrinologist at the University of Buffalo School of Medicine and senior author of studies presented Sunday at the annual meeting
of the American Diabetes Association in San Francisco.
Other researchers have noted that eating an unusually heavy or high fat meal may increase a person's risk of a heart attack as much as four-fold, apparently because hormones released into the bloodstream impair the function of the inner linings of the arteries.
Calories, fat, protein, carbohydrates and water, the major components of any food, are considered macronutrients.
Dandona said, "We think the influx of macronutrients may alter cell behavior and that genes are activated to produce more powerful enzymes and mediators that are potentially more damaging to the lining of the blood vessels.”
"On the other hand, we found that one way to render an unsafe meal 'safe' is to include antioxidant vitamins," Dandona said. "The pro-inflammatory effect of glucose is stopped if right at the outset you give vitamins E and C."
The study was done with nine healthy subjects who had fasted overnight and then ate a 900-calorie breakfast consisting of a ham-and-egg sandwich and hash browns from a fast food restaurant. Blood samples were taken before they ate and one, two and three hours afterward to measure the concentration of oxygen-free radicals, molecules that can damage blood vessel linings, and of several blood components that encourage or inhibit inflammation.
There was an average increase of free radicals over the baseline of 129 percent after an hour, 175 percent after two hours and 138 percent after three hours. Levels of blood components that increase inflammation were also up significantly, while levels of a factor that slows inflammation were reduced.
Similar studies showed that influxes of glucose alone, and an infusion of fatty acids, caused a reduction in the ability of blood vessels to expand and contract in response to changes in blood flow, critical for maintaining a healthy blood pressure.
In yet another study, eight subjects took 1,200 International Units of vitamin E and 500 milligrams of vitamin C before ingesting sugar water, and then in a second test took only the glucose.
Blood sampling showed that levels of free radicals and two inflammatory markers increased when glucose was taken alone, but did not increase when the subjects took the antioxidant vitamins beforehand.

Vitamin E Study on Prostate Cancer Is Called 'Tremendously Significant' In Search for Cure
Nutritional supplements such as vitamin E may be able to stop prostate cancer before it starts, according to health researchers.
They point to a major new trial involving 30,000 men to study the potential of vitamin E and also of a mineral, selenium, to help prevent onset of prostate cancer, which strikes about one in six men during their lifetimes.
One professor of clinical cancer prevention in Texas said the new trial is "tremendously significant," and a Cleveland Clinic physician has suggested that men enroll in the study, open to healthy men 55 and over, or 50 years and over for African American males.
In the trial, being conducted by the National Cancer Institute, part of the National Institutes of Health in Bethesda, Md., test subjects will receive Vitamin E alone, Vitamin E in combination with selenium, selenium by itself, or a placebo. The study is taking place in the
United States, Puerto Rico and Canada and is expected to continue for 12 years.
The Wall Street Journal recently reported on the trial, citing "compelling evidence" that nutritional supplements including Vitamin E may be able to "stop prostate cancer before it starts."
The newspaper quoted Elise Cook, assistant professor of clinical cancer prevention at the University of Texas M.D. Anderson Cancer Center in Houston: "The significance of this trial is tremendous. You could avoid the whole issue of treatment if you prevent it in the first
place."

New Hope for Sufferers of Age-Related Eye Illness
Large doses of vitamins C and E, beta carotene and zinc can significantly cut the risk of going blind from the leading cause of vision loss in people 65 and older, says a groundbreaking study out today.
If everyone at high risk for developing advanced age-related macular degeneration, or AMD, took the supplements, more than 250,000 Americans would be saved from going blind over the next 5 years, says study chair Frederick Ferris of the National Eye Institute. About 6 million Americans have moderate AMD, while another 1.8 million have advanced AMD, Ferris says.
No other treatment has been shown to slow or prevent the development of advanced AMD. "This is a rather remarkable finding," says Paul Sieving, director of the eye institute.
The study, reported in the Archives of Ophthalmology, involved 4,757 people, 55 to 80 years old. They were randomly assigned to one of four treatments groups: zinc, antioxidants, antioxidants and zinc, or a placebo. They were followed for about 6 years. The antioxidants consisted of 500 milligrams of vitamin C (about five times what most people get in their diet), 400 international units of vitamin E (13 times the recommended daily amount or RDA) and 15 milligrams of beta carotene. The 80 milligrams of zinc oxide (five times the RDA) was given with copper to prevent anemia.
The study classified subjects with AMD into three categories: early, intermediate or advanced. Those with early disease and most with intermediate had no vision loss. The classifications were based on the size and number of drusen, yellow deposits under the retina that characterize AMD.
In those with intermediate AMD or advanced AMD in one eye, the supplements combining antioxidants and zinc cut the risk of the disease progressing by about 25%. Separately, the antioxidants and zinc provided a smaller benefit.
Gerald Chader, chief scientific officer of the Foundation Fighting Blindness in Owings Mills, Md., says the new findings "are tremendously going to improve the quality of life for a number of people."
None of the treatments cuts the risk of cataracts, the scientists reported in a separate paper. And no benefit from any treatment was seen in subjects with no AMD or early AMD, whose risk of progressing to advanced disease during the study was very low.
Ferris cautioned such individuals against taking the supplements. Although his study saw few side effects, beta carotene can be risky to smokers, while high doses of zinc can cause anemia. Regular exams by an ophthalmologist can determine if and when supplements should be taken to prevent advanced AMD, Ferris says.

Natural vs. Synthetic Vitamin E
There is little difference between the natural and synthetic forms of most vitamins.
But with vitamin E, natural is better.
On a supplement label, natural vitamin E is listed as d-alpha tocopherol, d-alpha tocopheryl acetate, or d-alpha tocopheryl succinate. In contrast, synthetic forms of vitamin E are labeled with a dl-prefix.
Alpha-tocopherol is the most biologically active form of vitamin E, and its natural form consists of one isomer. In contrast, synthetic alpha-tocopherol contains eight different isomers, of which only one (about 12 percent of the synthetic molecule) is identical to natural vitamin E. The other seven isomers range in potency from 21 percent to 90 percent of natural d-alpha-tocopherol.
This may appear to be arcane nutritional chemistry, but it is key to understanding how the body absorbs natural and synthetic supplements differently. Molecular structure determines how the body uses vitamin E. Researchers have found that natural vitamin E assimilates far better than synthetic versions. Specific binding and transport proteins produced in the liver select the natural d-alpha form of vitamin E and largely ignore all other forms.
In one experiment, Japanese researchers alternately gave natural and synthetic vitamin E to seven healthy young women. It took 300 mg synthetic vitamin E to equal the blood levels achieved by a 100-mg dose of natural vitamin E.
In other studies at East Tennesse State University, Johnson City, US, researchers gave a variety of subjects either 30 mg/day or 300 mg/day vitamin E. Each supplement contained half natural and half synthetic vitamin E. Both forms were chemically labeled to distinguish one from other vitamin sources.
In blood levels, natural vitamin E increased twice as much as the synthetic form in healthy subjects and pregnant women. In umbilical cords, natural vitamin E levels were three times higher than synthetic vitamin levels.
Blood, however, is not vitamin E's final destination. So in the same study, researchers tracked short term tissue assimilation of natural and synthetic vitamin E in study participants prior to elective surgery. Tissue takes longer than blood to absorb nutrients, but after seven to 23 days of supplementation, natural vitamin E levels rose higher than synthetic levels.
Researchers conducted long-term tissue assimilation studies on two cancer patients. One patient took 30mg/day half natural, half synthetic vitamin E for one year, and the other took 300mg/day for almost two years. In both patients, blood and tissue levels of natural vitamin E rose twice as high as the synthetic.
Researchers at Oregon State University, Corvallis, Oregon, US, found the human body excretes synthetic vitamin E three times faster than the natural form. Although the international unit (IU) standard for vitamin E was meant to equalize the differences between natural and synthetic vitamin E, studies show otherwise. Last year, the National Academy of Sciences recognized natural vitamin E as the standard by which to judge synthetics. Natural vitamin E contains the molecule humans assimilate most effectively.

Vitamin E for your Brain
Taking natural vitamin E (an antioxidant) may help protect your brain as you age. A study at the Rush-Presbyterian-St. Luke's Medical Center, Chicago, found that among people 65 and older, those who consumed the most natural vitamin E had better memories. The three year study measured cognitive function in a community of senior citizens. The researchers concluded that taking antioxidants, like natural vitamin E, can help prevent Alzheimer's and other neurological problems that can result from aging.
"This study is important," said Martho Clare Morris, ScD, assistant internal medicine professor and principal researcher, "because most of the previous research has focused on antioxidant nutrients as treatment therapy in persons who already have (problems)... such as Alzheimer's or Parkinson's disease. There is limited study on whether dietary intake of antioxidant nutrients can protect against the disease from ever occurring.

Vitamins, Sex and Cervical CancerAntioxidants lacking in women with this cancer.
Could protection from cervical cancer be as simple as popping a vitamin pill? That may be a stretch, but a new study links certain nutrients with this cancer and upping them may be protective.
Women who have precancerous cervical lesions don't have enough of certain antioxidants - vitamin E and coenzyme Q10 (CoQ10) - and this makes them far more susceptible to developing cervical cancer, says new research presented at the 50th annual meeting of the American College of Obstetrics and Gynecology. Increasing those nutrient levels, say researchers, might offer some protection against this cancer.
"What we proved in this study is actually two-fold - we showed that women who have lower blood levels of certain antioxidants also have lower levels of these same nutrients in their cervical cells - and we learned that women who have these lower nutrient levels also are at greater risk for CIN - cervical intraepithelial neoplasia - a change in cervical cells that is the precursor to cervical cancer," says Dr. Magdy S. Mikhail, lead study author and researcher at Bronx-Lebanon Hospital Center in New York.
Antioxidants are nutrients that help neutralize the effects of free radicals - molecules that cause an oxidation process that eventually damages cells. Experts think that cell damage might be a precursor to cancer.
While a number of risk factors are linked to CIN - including smoking and taking birth control pills- by far the biggest factor seems to be infection with certain strains of HPV - human papilloma virus - a sexually transmitted disease. For this reason, cervical cancer is often thought of as a sexually transmitted disease. If the research is right, says Mikhail, upping your intake of certain nutrients may help prevent infection with HPV - or ultimately draw the line between HPV and cervical cancer.
"Perhaps nutrient levels may be key in understanding what it is about HPV that leads to cervical cancer," says Mikhail.
Others agree with the premise - but say it's too early to know for sure. "I have a hunch this may be correct, but I don't think we can confirm it yet - the control group was small, and it may not be statistically significant," says Dr. Thomas Caputo, chief of Gynecologic Oncology at New York Weill Cornell Medical Center in New York City.
However, Caputo also points out that several of his own patients with persistent and stubborn HPV infections have found relief through macrobiotic diets, which help concentrate nutrient intake.
"I do believe there is something to this nutrition issue - I just don't know for certain what the specific link is," he says.
What The Study Found
The research involved just over 100 women - 55 with confirmed CIN, and 20 who had cervical cancer. The control group was 27 women who had no cervical lesions at all. To begin the study, doctors measured the women's plasma blood levels for both CoQ10 and vitamin E.
Then they tested the cervical cells to see if they also lacked the antioxidants.
The result: Women who had either CIN or cervical cancer had markedly lower levels of both CoQ10 and vitamin E in their blood and in their cervical cells than the healthy women who were healthy.
While this was the first study to note the decrease of CoQ10 - a powerful antioxidant - it is not the first to make the correlation between vitamins and CIN. Published studies have also shown that vitamin C, vitamin E and beta carotene - all antioxidants - seem to be lower in women with precancerous cervical lesions or cervical cancer.
"The next step is to see whether or not increasing the intake of antioxidant nutrients can reverse the cancer process, or, more likely, act as a preventative, helping to keep the precancerous cells from becoming cancer, or even keep them from developing at all," says Mikhail.
Caputo agrees: "This is the tip of the iceberg - I don't think it's just these nutrients, there may also be subtle metabolic defects that either occur because the patient has the disease or occur and helps promote the disease."
What To Do
If you are a sexually active woman - thereby at increased risk for cervical cancer - doctors say be extra vigilant about eating a healthful diet, particularly one containing lots of fresh fruits and vegetables.
"This diet is healthy in general - and it could also help reduce the risk of cervical cancer," says Mikhail.
In terms of supplements, however, doctors are still reluctant to recommend using them as a cancer preventative. But, says Mikhail, "It couldn't hurt to take antioxidant supplements in reasonable amounts."
Caputo agrees: "Generally, I do believe in taking vitamins - and I do think diet can also play a role in disease prevention." By Colette Bouchez, Healthscout Reporter

Vitamins C And E Supplements Protect Lungs
Researchers have found that daily doses of vitamin C and E counteract the negative, inflammatory effect on lungs from the pollutant ozone. Previous studies have shown that even low levels of ozone have significant effects on lung function, as little as one hour after exposure. These effects have been previously studied by researchers exercising athletes indoors, under laboratory conditions.
Research teams feel that the antioxidants protect the lungs by reducing the lung's inflammatory response to the pollutants and ozone. Vitamin E and antioxidants are believed to have anticancer effects as well as heart protective benefits.
