HPRC Fitness Arena: Dietary Supplements
We’ve seen all the recent news and reports about energy drinks and the concern about the amount of caffeine in these products. Now a new wave of products is gaining attention, aimed at helping us relax, reducing our anxiety, and helping us sleep. These “relaxation beverages,” or “anti-energy drinks,” contain ingredients such as melatonin, valerian root, kava, St. John’s Wort, L-theanine, rose hips, and chamomile. A great number of relaxation beverages have been introduced into the market over the last three years, with names such as “Dream Water,” “iChill,” “Vacation in a Bottle,” and “Unwind.” Consumers of any age can buy these drinks in convenience stores, college campuses, and online.
Part of the problem with these relaxation drinks is that some of their ingredients, particularly melatonin, have not gone through the Food and Drug Administration’s (FDA) approval process required for all food ingredients to be designated as safe or GRAS (“generally recognized as safe”). Melatonin is a hormone made by the body, but it is also available as a supplement and is often used to treat sleep disorders and jet lag. The FDA sent a warning letter last year to the manufacturers of the “Drank” beverage saying, “there is no food additive regulation in effect that provides for the safe use of melatonin…Likewise, we are not aware of any basis to conclude that melatonin is GRAS for use in conventional foods.” The manufacturers of “Drank” want their product to be classified as a dietary supplement, not as a beverage, since the FDA scrutinizes foods and beverages much more closely than dietary supplements.
People who have liver problems, liver disease, or are taking prescription drugs should be cautious about using the herb kava, an ingredient found in some of these relaxation drinks. Kava has been linked to severe liver injury, and the FDA issued a consumer advisory in 2002 with a warning that kava-containing dietary supplement products have been associated with liver-related injuries, including hepatitis, cirrhosis, and liver failure. Valerian root, a medicinal herb, is used to treat sleep disorders as well as anxiety. Although some research has been conducted on the effects of valerian on insomnia, the data are mixed, and no studies have tested the safety and effectiveness of the combination of ingredients found in relaxation beverages.
The marketing of relaxation drinks is also of concern, as it is geared toward a younger crowd, with bottles resembling the look of popular energy drinks and shots. The concern is that young adults will think nothing of having more than one of these a day. Some of these beverages have warnings on their labels stating that users should not consume them before operating/driving machinery or if pregnant or nursing.
What’s the bottom line? Buyers beware! There’s no magic pill, and there’s no magic beverage. Try to determine the causes of your stress and/or insomnia, address those issues, and then work towards establishing a healthy lifestyle overall.
Godi International, Corp., located in South Florida is announcing a recall of Fruta Planta weight loss dietary supplements because the products contain Sibutramine an undeclared drug ingredient. Sibutramine is an FDA approved drug used as an appetite suppressant for weight loss. This poses a potential threat to consumers because Sibutramine is known to substantially increase blood pressure and/or pulse rate in some patients and may present a significant risk for patients with a history of coronary artery disease, congestive heart failure, arrhythmias or stroke.

A recent New York Times article reports that scientists are worried about highly caffeinated beverages like Red Bull, Rockstar, Monster and Full Throttle, which are popular among teenagers and young adults. According to the article, the often bizarre combination of ingredients in these drinks prompted three researchers from theHealth Science Center at Houston and the University of Queensland in Australia to examine what is known — and not known — about the contents of these beverages, which are sold alongside sodas and sport drinks in supermarkets, drugstores and highway rest stops.

The FDA held a press conference on 12/15/2010 announcing that it was sending a letter to all dietary supplement trade associations, as well as posting a message to consumers, about the growing problem related to the sale of various misbranded drug products masquerading as "dietary supplements."
A recent systematic review found that nutritional and herbal supplements may be an effective way to treat anxiety and anxiety related problems without serious side effects. Although scientists reported that positive outcomes may be due to a placebo effect*, based on the review, there is scientific evidence to support the use of certain nutritional and herbal supplements to treat these conditions. If you are currently being treated for anxiety, discuss with your physical the option of using or including a natural supplement.
* A placebo effect is the beneficial effect in a patient following a particular treatment that arises from the patient's expectations concerning the treatment rather than from the treatment itself.
The Montreal Gazette is reporting that a new study made public yesterday links glucosamine, a popular over-the-counter dietary supplement for joint problems with a risk of developing diabetes. The study, which was published in the Journal of Endocrinology, looks at in-vitro cell lines from mice and rats.
The experiment showed that the supplement triggers a mechanism intended to lower high blood sugar levels, but it also destroyed about 50 per cent of the cells by affecting SIRT1, a protein crucial to cell survival.

The Federal Trade Commission (FTC) recently filed a complaint against POM Wonderful products due to deceptive advertising. POM Wonderful has claimed that its products will reduce (or treat) heart disease, prostate cancer and erectile dysfunction. The FTC says that these claims are not supported by scientific research.
So, what’s a health claim and what’s considered acceptable advertising as such?
A health claim statement has to have a food substance, food, or dietary ingredient, and a health condition or disease. The Food and Drug Administration (FDA) has approved certain health claims that, based on scientific evidence, show a link between a food or supplement and a health condition or disease. Health claims cannot state that a food product or supplement can treat or cure a disease. It may claim to minimize a disease risk; for example, a product advertised as low sodium can state the approved claim that “diets low in sodium may reduce the risk of high blood pressure, a disease associated with many factors.”
Health claims shouldn’t be confused with structure/function claims. These claims do not have to be approved and reviewed by the FDA, yet they must be truthful in stating that a substance maintains structures and/or functions of the body. We see these claims on many fiber-rich products, like “fiber maintains bowel regularity,” or a dairy product stating that “calcium builds strong bones.” Unlike health claims, structure/function claims cannot be linked to a health-related condition or disease. Also, an important point to keep in mind: if a dietary supplement label makes a structure/function claim, it must also state this disclaimer: “This statement has not been evaluated by the FDA. This product is not intended to diagnose, treat, cure, or prevent any disease.”
There are also nutrient content claims. These describe the amount of a nutrient in a product. Descriptions such as free, low, high, and rich in are used, or other terms that describe the nutrient content to that of the content in another product, such as reduced, lite, less, or more.
Manufacturing companies want consumers to buy their products. We, as consumers, must be savvy as we try to choose products that are healthy for our families and us. False health claims are used on food products as well as dietary supplements. They claim to help us lose weight, cure diseases, and prevent memory loss. The FDA has not approved claims that focus on the treatment of diseases. They have, however, set forth regulations to authorize health claims after the scientific evidence has been presented and reviewed.
