Multivitamin benefits -
These benefits persisted—but did not increase—over the following two years of the study. Read More : What the Science Says About the Health Benefits of Vitamins and Supplements.
The improvements did not translate to other cognitive functions, such as executive functions like reasoning and other memory skills, but an earlier study by the same group found broader cognitive benefits among 2, people over 60 who were randomly assigned to take a daily multivitamin for three years or a placebo.
The benefit of taking a daily multivitamin for three years translated to a slowing of cognitive aging by just over three years, says Manson. The fact that the trial compared multivitamin users to those receiving placebo provides more confidence in the results, she says, and the study is only the second to analyze the effects of multivitamins on cognition in such a rigorous way.
The only other previous trial, the Physicians Health Study II , did not find any difference in cognition between multivitamin and placebo takers among 14, physicians.
But that study did not conduct cognitive tests of the participants at the start of the study to establish a baseline to which to compare the effects. In the Physicians Health Study, participants were evaluated after about 2. The researchers hope other groups try to replicate their findings to solidify any connection between multivitamins and cognitive health, and also generate more data into how the multivitamins may be contributing to improved memory.
The group plans to continue following the participants in the study to see if the benefits persist beyond three years; they also hope to study younger people, beginning at age 50, to see if the improvements might be greater if people start taking multivitamins earlier.

Knowledge about the optimal intakes of vitamins and mi nerals to prevent chronic diseases is not set in stone. More long-term studies looking at this relationship are needed. There is no arguing that multivitamins are important when nutritional requirements are not met through diet alone. For many diseases, but especially for cancer, only long-term trials are informative.
The following studies looked at the effect of multivitamins on specific diseases and include d healthy people as well as those w ith chronic disease s at the start of the study :. A randomized double-blind placebo-controlled trial provided a multivitamin or placebo to more than 14, male physicians, some with a history of cancer.
The results did not differ among men who had a history of cancer at the start of the study and men who were healthy at baseline. After 11 years, compared with the placebo, there was no significant effect of a daily MVI on cardiovascular events. Some research has suggested that the rates of death appear higher in people using multivitamins.
However, one major flaw in these studies was that many of the participants had already developed some type of serious illness. They may have started using vitamins after their health deteriorated, hoping for a benefit. But in those cases, taking a multivitamin might have been too late.
It is important to remember that a multivitamin cannot in any way replace a healthful well-balanced diet. The main purpose of a multivitamin is to fill in nutritional gaps, and provides only a hint of the vast array of healthful nutrients and chemicals naturally found in food.
It cannot offer fiber or the flavor and enjoyment of foods so key to an optimal diet. However, multivitamins can play an important role when nutritional requirements are not met through diet alone.
When this is the case, an expensive brand name is not necessary, as even standard store brands will deliver results.

The elderly are at risk for poor food intake for various reasons: difficulty chewing and swallowing food, experiencing unpleasant taste changes caused by multiple medications, or isolation and loneliness that can depress appetite.
They also have trouble absorbing vitamin B12 from food. The National Academy of Medicine, in fact, recommends that people over the age of 50 eat foods fortified with vitamin B12 or take vitamin B12 pills that are better absorbed than from food sources.
Getting enough folate , a B vitamin, is especially important for women who may become pregnant, since adequate folate can help lower the risk of having a baby with spina bifida or anencephaly.
For the folate to be effective, it must be taken in the first few weeks of conception, often before a woman knows she is pregnant. Yet in the U. Malabsorption conditions.
Any condition that interferes with normal digestion can increase the risk of poor absorption of one or several nutrients. Examples: Diseases like celiac, ulcerative colitis, or cystic fibrosis.
Surgeries that remove parts of digestive organs such as having a gastric bypass for weight loss or a Whipple procedure that involves many digestive organs.
Illnesses that cause excess vomiting or diarrhea can prevent nutrients from being absorbed. Alcoholism can prevent nutrients, including several B vitamins and vitamin C , from being absorbed. Certain medications.
Proton pump inhibitors prescribed for acid reflux and heartburn can prevent the absorption of vitamin B12 and possibly calcium and magnesium. A note on vitamin D For most people, the best way to get enough vitamin D is taking a supplement because it is hard to get enough through food.
Although some foods are fortified with vitamin D, few foods contain it naturally. Vitamin D production in the skin is the primary natural source of vitamin D, but many people have insufficient levels because they live in places where sunlight is limited in winter, or because they have limited sun exposure.
Also, people with darker skin tend to have lower blood levels of vitamin D because the pigment melanin acts like a shade, reducing production of vitamin D. Cancer A randomized double-blind placebo-controlled trial provided a multivitamin or placebo to more than 14, male physicians, some with a history of cancer.
Mortality Some research has suggested that the rates of death appear higher in people using multivitamins. It showed that women over the age of 55 who took multivitamins were at higher risk for dying than those who did not.
As a result, it is unknown whether the women were already taking vitamins when they became ill, or if they became ill and then started taking vitamins. In women who were already sick, taking vitamins was unlikely to lower their risk of dying. The benefit appeared strongest for participants with a history of cardiovascular disease CVD ; this result may have been due to lower baseline blood levels of certain vitamins and minerals or susceptibility to drug interactions causing lower nutrient levels in patients with CVD, as the authors confirmed had been shown in prior observational studies.
The COSMOS-Web trial followed 3, older adults, examining their memory and executive functioning specific to the hippocampus region of the brain by using neuropsychological tests.
