Still, more than half of American adults have taken them.

Below is our take on the potential risks and benefits of each, plus advice about who should consider taking them.

Some marketers of supplements would like you to think that B vitamins provide a power boost. The vitamin supplements do help you extract energy from food, but most people get plenty through their diet. Extra doses won't necessarily make you more energetic. Nor do the vitamins appear to reduce heart risk. In an October analysis of trials involving more than 37, people at high risk of cardiovascular disease, those who took folic acid, a B vitamin, did have lower levels of homocysteine—a chemical linked to an increased risk of heart disease—compared with those who took a placebo.
But they didn't have significantly fewer heart attacks or strokes. Nor did the pills reduce the risk of cancer or premature death. Preliminary research does suggest that a combination of B6, B12, and folic acid might reduce the risk of age-related macular degeneration, a progressive eye disease that causes vision loss. But larger trials are needed to confirm that. Bottom line. Most people don't need B vitamin supplements, but they might make sense for a few groups:.
People whose diets include lots of vitamin C—rich fruit and vegetables appear to have a lower risk of heart disease and certain cancers, among other diseases. But clinical trials testing isolated doses of the vitamin in pill form have mostly failed to find any protective benefit against those diseases.
Are they worth taking?
Some data though sometimes from questionably designed studies has even suggested that supplements of antioxidant vitamins, including C, might pose risks for people being treated for cancer by protecting tumor cells along with normal ones. There's some evidence that mg or more of vitamin C a day might improve cold symptoms in smokers and seniors, though it won't prevent colds. And there's some preliminary evidence that a supplement combining large doses of vitamins C and E, beta-carotene, copper, and zinc might slow the progression of macular degeneration. In general, just 90 mg of vitamin C a day for men and 75 mg for women is sufficient.
Smokers should add an extra 35 mg a day—the amount in about half an orange—to help repair damage from cancer-causing free radicals. Vitamin C can enhance iron absorption, so avoid high doses if you have hemochromatosis, a condition in which the body absorbs and stores too much iron.

Talk with your doctor before taking any antioxidant supplement if you are undergoing cancer treatment. That's especially true during winter months—one reason the Institute of Medicine, which advises the government on nutrition recommendations, decided on an increase in the suggested daily intake. While that might help improve vitamin D intake in certain populations, "the epidemic of vitamin D deficiency in North America is largely a myth," Manson says. Indeed, population studies have found that low blood levels of the vitamin are less common than previously thought.
And while some large, observational studies have linked higher vitamin D intake to a lower risk of cancer, heart disease, and other conditions, they can't prove cause and effect; only large, randomized clinical trials can do that. And people with low levels of vitamin D might have other risk factors, such as obesity, a sedentary lifestyle, or a poor diet, that could increase their likelihood of disease, Manson points out.
Until research confirms the benefit of higher doses, stick with the IOM's recommendation: IU for adults up to age 70 and IU for those older than If you get some midday sun exposure during the warmer months and regularly consume vitamin D-rich foods, such as fatty fish, eggs, or fortified dairy products, you probably don't need vitamin supplements. People who are middle-aged or otherwise at risk of vitamin D deficiency, including those who are overweight or have darker skin,might need supplements. Even then, the amount in most multivitamins is probably enough.
Don't exceed 4, IU a day. If you're unsure about your vitamin D status, request a blood test. On paper, vitamin E appears to strengthen the immune system and reduce the risk of heart disease and cancer. Attend a meeting, join a conference call or contact others in the business to hear about their experiences and insights. Try to find people who are not over-the-top in their praise.
Research online to learn about other people's experiences, good and bad. Nearly all companies will have negative comments and complaints, but companies that have complaints about non-payment, poor quality products or services or no response to support requests should be avoided. Study the marketing plan. Company recommendations for marketing can vary and include one-on-one presentations and party sales. Many companies now offer websites and other online marketing tools, but ultimately, direct sales is a person-to-person business.
Companies also have limitations and restrictions related to marketing. For example, some companies don't allow you to use its name in marketing. Read the contract. Many problems that consultants experience in direct sales can be avoided by reading the contract.
Sponsors don't always cover every detail of what's involved in being a consultant. It's your business, and the agreement is a legal contract, so don't sign it until you've read every word and understand all the terms. Find a sponsor who will train and support you, and you get along with.
Some sponsors may be pushy and others may be laid back. You need to find someone you can work with. Remember, though, that it's your business. A sponsor is there to help you, but won't build your business for you. Start your business. Once you've found a company with products or services you like and business plan you can live with, sign the contract and get with your sponsor to help you get started.
