However, this has not Nutritonal Nutritional supplements advice or disproved. For example, a Stress management at home can say that it Nutritiona energy levels. Talk with your healthcare team or a dietitian about whether supplements might be right for you. Vitamin E, which was initially thought to protect the heart, was later discovered to increase the risk for bleeding strokes.

Nutritional supplements advice -

But many careful randomized clinical trials have not shown any benefit against heart disease, cancer, or other illnesses. And that's not the worst of it. In fact, even moderately high doses of vitamin A increase the risk of hip fractures, and high levels of vitamin A have been linked to an increased risk of prostate cancer; beta carotene increases lung cancer risk in smokers; and vitamin E increases the risk of prostate cancer and has been linked to an increase in respiratory infections, heart failure, and the overall death rate.

Do not take antioxidant supplements. One exception: people with moderate or advanced age-related macular degeneration AMD benefit from special antioxidant supplements that also contain zinc.

Unfortunately, though, this preparation does nothing to prevent AMD in people who have healthy eyes. Vitamin B 12 is found only in animal-based foods, so strict vegetarians may need supplements. In addition, many older people don't make enough of the stomach acid that's needed to liberate B 12 from animal products so it can be absorbed.

But B 12 is also added to fortified grain products and other foods, and this synthetic B 12 is easy to absorb even without stomach acid. That means a single bowl of cereal can provide your RDA of 2.

Still, if your fortified grain consumption is erratic, a B 12 supplement is reasonable. Folate is more complex. The vitamin is essential for the production of red blood cells, and it has an important role in DNA production and in repairing defects in the genetic code.

Although folate is present in a variety of leafy green vegetables, fruits, legumes, and meats, until the late s, many Americans didn't get their RDA of mcg from foods — and folate deficiencies during pregnancy sharply increase the risk of devastating birth defects.

That's why the U. and Canadian governments issued regulations mandating folic acid fortification of all grain products including cereal, bread, flour, pasta, and rice from onward. Folate fortification has eased the birth defect problem, but obstetricians still recommend supplements for women who are trying to conceive or who are already pregnant.

Despite their iconic status, there is no evidence that multivitamins enhance health and well-being or prevent illness.

Without disputing these conclusions, many doctors have continued recommending and taking multivitamins. One rationale is that they are a convenient and inexpensive way to get vitamin D — but most preparations provide just IU, much less than the to 1, IU currently in favor.

Fish oil. For years, doctors have known that people who eat fish regularly enjoy some protection against heart disease and stroke. But check with your doctor first. People who eat fish at least twice a week are not likely to benefit from extra fish oil. Most people think of fiber supplements as a treatment for constipation.

But a high intake of fiber has many potential benefits for several health conditions, ranging from heart disease and obesity to hernias, varicose veins, and diverticulitis. The National Academy of Medicine recommends 38 grams of fiber a day for men younger than 50, 30 grams a day for older men, 25 grams a day for women younger than 50, and 21 grams a day for women over Whole grains, fruits, vegetables, nuts, and seeds are the best sources of fiber, but many people need supplements to meet these goals.

If you need supplementary fiber, consider psyllium, which has the added benefit of lowering cholesterol levels. Few men had heard of this mineral until , when American researchers reported that it appeared to reduce the risk of prostate cancer.

Subsequent reports were mixed, raising doubts. Then in , a 35,man multinational trial of selenium and vitamin E, alone or in combination, reported that neither selenium nor vitamin E had any benefit against prostate cancer.

Selenium also appears to increase the risk of diabetes, and earlier studies dashed preliminary hopes that the supplement might protect against heart attacks. Selenium is not for you. It's a disappointing scorecard. Most people stand to benefit from vitamin D, many from fiber, and some from fish oil.

And sorry to say, popular supplements used to treat medical problems fare no better. It's often hard to balance sober scientific judgments against simple, forceful claims for health in a pill.

If you are considering taking a supplement, here are a few cautions:. Until or unless better oversight is available, supplements are likely to remain the Wild West of American health.
