    Should you be taking vitamins?

    Liz Szabo reports for the New York Times that older Americans are popping supplements like candy. Doctors may recommend certain vitamins like vitamin D and folic acid, and dozens of others are marketed widely. But, the evidence suggests that most of these supplements offer no health benefits for otherwise healthy individuals and that some ingredients in some supplements do harm. Should you be taking vitamins?

    If you are otherwise healthy, speak with your doctor. You should likely skip the vitamin pills and instead eat a balanced diet. The preponderance of independent studies on almost all supplements suggests that the benefits are at best negligible and the dangers, at times, significant. For example, the biggest studies show that  vitamin E and folic acid supplements do not promote heart health. What’s worse, the studies show that too much vitamin E can mean you are at higher risk of heart failure, prostate cancer and death from any cause.

    Still, nearly seven in ten older adults take at least one vitamin and nearly three in ten take four or more vitamins.  There appears to be a misplaced belief that you can get more of the nutrients you need from vitamin pills and that more vitamins in your system is better for your health. But, pills are generally no substitute for eating a healthy diet, some ingredients in some vitamins can cause serious health risks, and taking more vitamins can be harmful to your health.

    Before believing the “experts” and spending your money on a supplement, you might want to review the scientific evidence on www.Cochrane.org. Cochrane is a global independent network of researchers, professionals, carers, patients and people interested in health. The people at Cochrane “gather and summarize the best evidence from research to help you make informed choices about treatments.”

    You can read the independent research findings about these vitamins on Just Care:

    John Oliver: When should you believe the science?

    When should you believe the science? John Oliver makes a compelling case on Last Week Tonight that you should not put much faith in what the media reports on the latest scientific studies. For example, you can find numerous studies showing that tea, tomatoes, beef and eggs cure cancer and many more showing that they cause cancer.

    The solution is not to disregard the science. But you should not give too much credence to individual studies. On top of small sample sizes in many studies, public relations firms often distort study findings and oversimplify the science.

    When it comes to health questions, we recommend that you visit www.cochrane.org to keep your faith in the science. Cochrane is an independent non-profit organization that looks at as many studies as possible on a particular health topic to provide the best assessment of what we know from the science.  Check it out. 

    In the meantime, watch the video below to learn more about the flaws in studies the media reports and have a good laugh, or cry. Also, check out Just Care advice on vitamin supplements, including vitamin B6, vitamin B12, vitamin C, vitamin D and vitamin E.

  • Vitamin B12 supplements

    Vitamin B12 supplements

    Is there any evidence that vitamin supplements benefit a healthy person? You’ve heard me ask this question before, about vitamin E supplements , about vitamin B6 supplements, and about vitamin C supplements. The answer is no. And, the answer is no for vitamin B12 supplements as well.

    Forget the advertisements. There is no rationale for otherwise healthy people to take a vitamin B12 supplement to improve their cognitive function or for any other reason.

    Not only should you stop before buying vitamin supplements–watch John Oliver for a funny explanation here, but there is also concern that supplements you buy at the drug store or vitamin superstore are not what you think they are. Because the FDA does not regulate these supplements, they may not be safe or as described on their label, either as pure or as strong.

    This all said, you should talk to your doctor if you are feeling weak or tired, or have sensory problems, including tingling in your feet or hands or you are experiencing memory problems. Some people cannot absorb B12 from food or are not receiving enough in their food because of dietary choices (e.g, vegetarians) and may benefit from an oral B12 prescription or an injection after laboratory testing demonstrates a B12 deficiency. It could prevent further decline or even reverse these conditions.  And, if you are a vegan you should talk to your doctor about taking a B12 supplement because the way to get B12  is through eating clams, salmon, trout, liver, beef, cereal and eggs and drinking milk, most of which  is lacking in a vegan’s diet.

    Keep in mind though that you should not decide on your own to take a B12 supplement no matter what symptoms you have. Vitamin B12 supplements should be used cautiously if you have any of a number of health conditions or if you are allergic to cobalt. So, do not go out and buy a vitamin B12 supplement without first talking to your doctor.
