This study is off, by well more than a mile, and here's why.
First of all the report gives no information about who provided the funding or the supplements. Remember that Pfizer's junque vitamin Centrum gets to tout all the marvelous benefits of viatmins. Because its Pfizer, a big campaign donor to the current administration, whose lobbyists get to participate in writing new drug legislation a when no one else can, also gets its vitamins paid for in the Senior drug payola to the drug companies program. If it was anyone else or some small company any claim is off limits without raising the ire of the FDA, strongly protecting the drug companies from the other side of the door.
Another important issue not reported in this study is that the amounts provided participants is extremely low in comparison to therapeutic dosing, or in what we refer to as orthomolecular medicine.
What the study failed to do was to provide the basic requirement of vitamin c for an adult. This happens to be 3000 mg a day because humans do not make their own vitamin C as do primates and other animals. This basic amount was determined through primate studies.
Therapeutic doses are substantially higher in many cases. Right now I am taking 12500 mg daily in five divided doses because it is harvest where I live and the dust is causing me to have unhappy lungs. With the vitamin C at this level I have no respiratory issues and this reduces stress on my heart. I too am in the age range of this study's participants. In addition I take non-soy vitamin E, 800 IU daily and a combination vitamin A / Beta Carotene tablet of 25,000 IU a day. Many people, including researchers, may not know that beta-carotene cannot convert to vitamin A alone.
"The women consumed either 500 milligrams of ascorbic acid (vitamin C) every day, 600 international units of vitamin E every other day, or 50 milligrams of beta carotene every other day."
In itself, the above reference to the study informs me that the outcome was to show vitamins do no good for health.
Don't be fooled, see more here from the experts.
And as far as getting enough vitamins in the diet is groundless because of corporate agricultural methods and food processing, all permitted by your government.

Common vitamins no help for women's hearts: study -
Middle-aged women at risk for heart disease received little benefit from taking vitamins C, E or beta carotene, researchers said on Monday.
Though vitamin supplements provided no heart benefit, eating a diet rich in those vitamins does make for healthier heart, their study noted.
Experts believe a nutritious diet rich in these vitamins protect the body's cardiovascular system by counteracting compounds known as "free radicals." These harmful compounds build up in the body and can damage artery linings, encourage blood clots and alter the function of blood vessels.
"Single antioxidants (vitamins) may not reflect the complex vitamins and nutrients found in foods, which may explain the discrepancies between most intervention trials and studies of fruits and vegetables," wrote study author Nancy Cook of Brigham and Women's Hospital and Harvard Medical School in Boston.
"While additional research into combinations of agents, particularly for stroke, may be of interest, widespread use of these individual agents for cardiovascular protection does not appear to be warranted," she concluded.
Among the more than 8,000 women, average age 61, involved in the study only a combination of vitamins C and E conferred a slightly lower risk of stroke compared to placebos.
The participants were tracked for roughly nine years for fatal heart disease, heart attacks, strokes and heart-related surgery, the study published in the Archives of Internal Medicine said. Heart disease is the leading cause of death in the industrialized world.
"Do we expect these supplements to reverse 30 years of heart disease? Of course they won't," said Andrew Shao of the Council for Responsible Nutrition, a trade group for the industry that produces $20 billion in U.S. states annually.
"But studies show that supplementation with modest amounts of antioxidants over a long period of time, 10 years or more, (produces) modest benefits," he said. "They're subtle, as should be expected when you're talking about nutrients and not pharmaceuticals," or prescription drugs.
Importantly, the study showed taking the supplements did not harm the women, Shao said, as some recent research has suggested based on deaths from all causes.
The women consumed either 500 milligrams of ascorbic acid (vitamin C) every day, 600 international units of vitamin E every other day, or 50 milligrams of beta carotene every other day. Some consumed more than one.
