The Truth About Vitamins And Supplements: How To Protect Yourself

Prepared Patient Publication Logo Vitamins, herbs and other dietary supplements are sold as natural alternatives to pharmaceuticals and many people turn to them in an attempt to improve their health. Others seek supplements to lose weight or after hearing that they can help with serious medical conditions. These products are now used at least monthly by more than half of all Americans—and their production, marketing and sales have become a $23.7 billion industry, according to the Nutrition Business Journal.

What Are Dietary Supplements and How Are They Regulated?
98-year-old Bob Stewart, a retired podiatrist and senior Olympian, credits his use of supplements for his healthy aging. Writer Betsy McMillan, a mother of two now adult children, however, nearly suffered permanent liver damage due to a supplement that contained potentially fatal levels of niacin.

Unlike pharmaceuticals—which must be FDA-approved as safe and effective before they can be marketed—supplements are considered as foods by regulators and assumed to be safe until proven otherwise. Although pharmaceutical manufacturers face inspections to ensure that the right dose is in the right pill without dangerous contaminants, supplements do not undergo such intense government scrutiny.

Treating The Common Cold

For the last week I have had a cold. I usually get one each winter. I have two kids in school and they bring home a lot of viruses. I also work in a hospital, which tends (for some reason) to have lots of sick people. Although this year I think I caught my cold while traveling.  I’m almost over it now, but it’s certainly a miserable interlude to my normal routine.

One thing we can say for certain about the common cold — it’s common. It is therefore no surprise that there are lots of cold remedies, folk remedies, pharmaceuticals, and “alternative” treatments. Finding a “cure for the common cold” has also become a journalistic cliche — reporters will jump on any chance to claim that some new research may one day lead to a cure for the common cold. Just about any research into viruses, no matter how basic or preliminary, seems to get tagged with this headline. (It’s right up there with every fossil being a “missing link.”)

But despite the commonality of the cold, the overall success of modern medicine, and the many attempts to treat or prevent the cold — there are very few treatments that are actually of any benefit. The only certain treatment is tincture of time. Most colds will get better on their own in about a week. This also creates the impression that any treatment works — no matter what you do, your symptoms are likely to improve. It is also very common to get a mild cold that lasts just a day or so. Many people my feel a cold “coming on” but then it never manifests. This is likely because there was already some partial immunity, so the infection was wiped out quickly by the immune system. But this can also create the impression that whatever treatment was taken at the onset of symptoms worked really well, and even prevented the cold altogether.

What Works

There is a short list of treatments that do seem to have some benefit. Nonsteroidal anti-inflammatory drugs (NSAIDs), like aspirin, ibuprofen, and naproxen, can reduce many of the symptoms of a cold – sore throat, inflamed mucosa, aches, and fever. Acetaminophen may help with the pain and fever, but it is not anti-inflammatory and so will not work as well. NSAIDs basically take the edge off, and may make it easier to sleep. Read more »

McDonald’s Vs. DASH: Two Days, Two Diets

This week I’ve been trying to eat according to the DASH guidelines for lowering blood pressure. It actually hasn’t been too difficult — partly because I’m not following their strictest guidelines, which call for just 1,300 milligrams of sodium and 16 grams of saturated fat a day. I’ve been shooting for 2,300 milligrams of sodium and 22 grams of saturated fat.

In 2003, I tried a somewhat different “diet,” which in some ways was more difficult to follow, even though it only lasted one day. My son Jim (then age 11) and I ate every meal at McDonald’s for an entire day (yes, this was before Super Size Me). We recorded the experience on the Web. I thought it would be interesting to compare my day at McDonald’s to a typical day on DASH. Read more »

Gout Prevention And Vitamin C

This past month, I saw a couple of patients in the emergency department who suffered from gout. When I was a medical student at Duke in the early 1970s, we commonly encountered patients with this disease, because of epidemiological factors that clustered in the southeastern U.S. Today on the west coast, we don’t encounter it as commonly. However, for those persons who suffer from gout, it’s a big deal. An acute attack of gout, caused by uric acid crystal formation and the attendant inflammation and pain, can ruin a few days of activity, or even cause a trip to be terminated.

There are a few approaches to treating a person with an acute flare of gout. The current mainstays are administration of nonsteroidal antiinflammatory drugs (NSAIDs), such as naproxyn, or antiinflammatory drugs in the form of corticosteroids. Colchicine is less commonly used.

How does a person prevent gout? The basic tenet is to minimize uric acid production in the body, and/or to prevent its precipitation into crystals within the body’s tissues and fluids. There are risk factors associated with suffering from gout, so doing one’s best to mitigate these is the proper approach. Here are some of the commonly accepted risk factors:

1. Being obese or overweight
2. Eating purine-rich foods, although there is some controversy about this, since some researchers have identified certain purine-rich foods that, in their assessment, did not seem to be associated with an increased propensity to gout.
3. Drinking excessive quantities of alcohol. This has been recognized for centuries.
4. Elevated blood pressure
5. Lead poisoning. This is one of the reasons that we saw a certain form of gout, known as saturnine gout, when I was a medical student. Persons in the North Carolina region who manufactured moonshine whiskey using an apparatus (still) that included leaded radiators from cars suffered from gouty attacks.
6. Genetics – not much you can do about selecting your parents…
7. Kidney insufficiency or failure
8. Medication use that promotes increased uric acid in the bloodstream
9. Certain blood disorders, such as leukemia or lymphoma
10. Low thyroid function

There was recently a very interesting article that appeared in the Archives of Internal Medicine, entitled “Vitamin C Intake and the Risk of Gout in Men. A Prospective Study,” authored by Hyon K. Choi and colleagues (Arch Intern Med 2009;169(5):502-507). They sought to determine whether or not higher vitamin C intake significantly reduces serum uric acid levels, and therefore the risk of suffering from gout.

Adapted from the abstract to the article: We prospectively examined, from 1986 through 2006, the relation between vitamin C intake and risk of incidents of gout in 46,994 male participants with no history of gout at baseline. We used a supplementary questionnaire to ascertain the American College of Rheumatology criteria for gout. Vitamin C intake was assessed every 4 years through validated questionnaires. During the 20 years of follow-up, we documented 1317 confirmed incident cases of gout. Compared with men with vitamin C intake less than 250 milligrams per day (mg/d), the multivariate relative risk (RR) of gout was 0.83 for total vitamin C intake of 500 to 999 mg/d, 0.66 for 1000 to 1499 mg/d, and 0.55 for 1500 mg/d or greater.

The conclusion is that higher vitamin C intake is independently associated with a lower risk of gout. Supplemental vitamin C intake may be beneficial in the prevention of gout. This is, of course, only a single analysis, so warrants further investigation by others before the assumption can be completely made that this will bear out across a larger population. Vitamin C may not really do anything to prevent a “cold,” but perhaps it is useful to prevent gout.
