Should You Swallow? The Vitamins and Supplements You Really Need

  • Comment Comments (7)

Taking vitamins to stay healthy seems like a no-brainer. But new research has found that supplements aren't the magic bullet we've been led to believe. One recent review of 78 studies found that antioxidant supplements don't reduce the risk for death from disease; in fact, in some cases they actually raise it. And now calcium supplements, which so many of us have been dutifully popping for years, have been linked to an increased risk of heart attacks. Say what? But don't trash your stash just yet. Read on so you can make the best decisions for your body.

5 Facts About Vitamins and Your Health

Fact: Vitamins don't cancel out bad health habits.

"There are so many different disease-causing culprits in our lives that one vitamin cannot protect against them all," says Mark Moyad, MD, a FITNESS advisory board member and the director of preventive and alternative medicine at the University of Michigan Medical Center. "Vitamins can't significantly undo the toll that risk factors like smoking, excess alcohol, air pollution, obesity, and lack of physical activity take on our health," adds Jeffrey Blumberg, PhD, the director of the Antioxidants Research Laboratory at Tufts University. In fact, research suggests that some people may be more likely to put their health on the line when taking vitamins, because they believe the pills will shield them from harm.

Fact: Megadoses are useless and possibly even harmful.

"Our bodies have individual requirements for each nutrient, and once they've been met, we don't get an additional benefit from taking more, either from food or supplements," says Alice H. Lichtenstein, the director of the Cardiovascular Nutrition Laboratory at Tufts. Taking too much calcium, for example, can cause kidney stones and may increase your risk for heart attacks. What's more, some vitamins and minerals rely on the same mechanisms for absorption, "so if you flood your body with one compound, you may interfere with the absorption of other nutrients," Lichtenstein says.

Fact: What you put on your plate matters most.

Supplements are not a substitute for the nutrients found in whole foods. "Many compounds in foods may work synergistically to fend off disease," Blumberg says. Spinach, for instance, is a great source of iron, but it also contains literally thousands of other nutrients; an iron supplement contains only one. As long as you're eating a varied diet, it's extremely difficult to OD on the vitamins and minerals you get from foods, but exceeding your RDA is easy when you're popping supplements.

Fact: You're already getting enough of the key nutrients you need.

More than 90 percent of Americans have the recommended levels of several essential nutrients, such as vitamins A and D and folate, in their bodies, a new report by the Centers for Disease Control and Prevention found. "Many common foods that we eat -- for example, breakfast staples like cereal, milk, eggs, bread, and orange juice -- may be fortified with a variety of vitamins, including folic acid, calcium, vitamin D, and niacin," Lichtenstein says. Some foods are required by law to be fortified: Since 1998 the FDA has mandated the addition of folic acid to many grain products, like flour and pasta, to ensure that women of childbearing age maintain adequate blood folate levels to prevent neural tube defects. Plus many manufacturers voluntarily fortify foods (think eggs or peanut butter with added omega-3 fatty acids) to make them more appealing to health-conscious consumers. This practice, which results in what are called functional foods, is now a $41-billion-a-year industry.

Fact: Still, you're low in certain vitamins and minerals.

The CDC report found that women ages 20 to 39 have the lowest intake of iodine, a substance that is necessary for fetal brain development during pregnancy, and that African- and Mexican-Americans are most likely to fall short on vitamin D, which can help prevent conditions like osteoporosis, colds, and flu. In such instances, vitamins can help fill nutritional gaps. Supplements may also be a good idea if you no longer eat certain food groups because of certain dietary regimens, such as vegetarianism, or food allergies, Blumberg says.

I have an auto immune diesease... if I do not take supplements I certainly do not get what I need from my food (and I eat very clean) as my body is not capable of storing high enough levels of iron (ferratin in fact), magnesium, b vitamins and calcium. At one point I was in such a state of malapsorption that I was 100lbs and very ill. I think that you must tread carefully when informing people that they should or should not as everyone has individual issues and needs.

Passionatefor1- nail on head. The author of this article had an agenda because there was no attempt to discern information and find truth in the information that was extrapolated. It is a shame that someone with no real knowledge, depends on their preconceived notions to be validated, instead of actually doing the work of a journalist.

passionatefor1 you beat me to it, totally agree with you. Processed food is dead food. If supplements are not needed why do they put em in our cerial and bread? No enzymes in processsed food either. Next time you are feeling fatigued try a high quality multi vitamin and see ur energy come back, which is proof you need it and they work. I can't digest any of the junk I eat at restaurants without a broad spectrum enzyme supplement like No-Bloat (but I still go because I love to eat out :).
