DMAA products continue to dwindle

HPRC has updated its list of DMAA-containing products, showing that 20 more products have been discontinued or reformulated to exclude the ingredient.

Since we first posted our list of DMAA-containing dietary supplement products in December 2011, the number of products being manufactured with this ingredient has continued to decline. Our most recent update shows only 79 dietary supplement products still being manufactured with DMAA; over the past 13 months more than 110 products have been discontinued or reformulated to exclude DMAA. Our search does still occasionally turn up products with DMAA that were not on our previous lists, but this is increasingly rare, with only four additions since our last update in October 2012.

Green coffee beans—health or hype?

Weight-loss supplements with green coffee beans have been popular lately, but some products have more in them than just coffee beans. Get the facts about ingredients and always read product labels carefully.

It can be tough figuring out the truth about the health benefits of many natural products. One product that’s getting a lot of attention these days is green coffee beans. As a Warfighter looking for ways to optimize your performance or perhaps drop some weight quickly, it’s easy to be overwhelmed by all the marketing hype and claims, especially if it’s an appealing message. Make sure you get the facts.

Green coffee beans are the raw, unroasted seeds or “beans” of the Coffea plant. They contain a chemical called chlorogenic acid (CA) that supposedly offers some health benefits. Roasting reduces the amount of CA in coffee beans; as a result, green coffee beans contain more CA than the roasted beans you use for your morning coffee. Some research suggests that CA might prevent heart disease, diabetes, and high blood pressure, and help with weight loss. But it’s important to note that most of this research is preliminary, and there just isn’t enough evidence to say that CA will definitely help with any of these health conditions.

Although no serious side effects have been reported from green coffee beans in their natural form, some dietary supplement products containing green coffee beans have been found to contain undeclared drugs, insects, and mold. Of the 126 products containing green coffee beans ranked by the Natural Medicines Comprehensive Database, 40 have been assigned a rating of “1” or “2,” which indicates there are serious concerns about their safety and effectiveness. None have a rating in NMCD’s green zone, which suggests that there are some concerns about them all. Note also that green coffee beans are not always the only active ingredient, so be sure to check the product label.

It’s also important to note that green coffee beans contain caffeine. Side effects of consuming too much caffeine are all too familiar—difficulty sleeping, rapid or irregular heartbeat, nervousness, nausea, and vomiting. Pregnant and breastfeeding women, or those who have been diagnosed with certain medical conditions (including anxiety, diabetes, irritable bowel syndrome, high blood pressure, or osteoporosis) should check with their doctor before consuming green coffee beans. For more information on caffeine, read the OPSS FAQ on caffeine.

Air Force studying caffeinated drinks

Air Force conducting study on 12 bases on the use of caffeinated drinks.

The Air Force is conducting a study on the use of energy drinks among active-duty Air Force personnel and civilians. According to the Army and Air Force Exchange Service (AAFES), Monster Energy was the top-selling cold beverage last year in the AAFES worldwide, and due to continuing concerns about the effects of energy drink consumption, the Air Force has started its own survey that targets 12 bases in Europe and the U.S. For the complete story, read the article in Stars and Stripes.

Energy drinks and service members

Energy drink consumption among service members may lead to sleep issues.

The Centers for Disease Control and Prevention (CDC) has reported that the consumption of energy drinks by service members can lead to sleep deprivation and impaired performance. The report outlines a study of more than 1,200 service members deployed in Afghanistan that found roughly 45% of those surveyed consumed at least one energy drink daily. Those who consumed three or more energy drinks per day—about 14%—had sleep issues that disrupted their performance. While more research is needed to determine the full effects of energy drink consumption on sleep, service members should be aware of their daily caffeine consumption.

Caffeine and performance—limit your intake for best performance.

Caffeine shouldn't be a replacement for sleep, and too much degrades your physical performance.

Caffeine in moderate doses can boost both physical and cognitive performance. It can help maintain alertness when you are doing long boring activities such as highway driving. It is especially effective for enhancing alertness and mental performance when individuals are sleep deprived. However, if you can, it is better to get the sleep your body needs. The suggested level of intake for enhancing cognitive performance is relatively low—one or two cups of coffee or one or two energy drinks (about 80-200 mg of caffeine). Larger doses can cause side effects (e.g. nervousness, irritability, shakiness, and trouble sleeping). It is very important not to consume large amounts of caffeine before trying to sleep. Blood levels of caffeine peak at about 60 minutes and are maintained for approximately two to three hours. Thus, although each person is different, another dose after four hours may confer additional benefits for activities of long duration or when alertness must be maintained.

The bottom line is, more caffeine will not improve performance—and may actually degrade it due to various negative side effects at higher doses.

FDA investigating adverse events linked to energy drinks

Reports of adverse events —including five deaths—possibly linked to Monster Energy drinks are under investigation by the FDA.

The Food and Drug Administration (FDA) is investigating five deaths and a non-fatal heart attack that may be linked to Monster Energy drinks. The FDA has pointed out that while the investigation is going on, it does not mean that Monster Energy drinks caused these adverse events, which were reported to the FDA over a span of eight years. Other adverse event reports have been associated with consuming the energy drinks. Read the New York Times article here, as well as this one from NBC News.

Energy drinks and adolescents

Energy drink use by adolescents is on the rise, and misuse of these beverages may stem from confusion about using energy drinks for rehydration.

Energy drinks are marketed to improve physical and mental performance, mainly to “boost energy.” Adolescents are getting hold of energy drinks more often, in part due to heavy marketing of sports drinks with athletic superstars, causing adolescents to confuse energy drinks for sports drinks. Energy drinks contain large amounts of caffeine and other stimulants, while sports drinks contain carbohydrates and electrolytes and are intended for use when athletes (including adolescents) are engaged in prolonged, vigorous exercise. Adolescents have already had problems combining energy drinks and alcohol, which has led to risky behavior. The American Academy of Pediatrics has guidelines for the use of energy drinks and sports drinks by adolescents.

DMAA list update for October 2012

HPRC’s latest review of DMAA-containing products shows that 89 have been discontinued or reformulated since the list was first compiled nine months ago.

HPRC’s list of DMAA-containing dietary supplement products has been reformatted, revealing that many are no longer being manufactured or distributed. A number of manufacturers now indicate on their websites that products previously containing DMAA have been reformulated. DMAA-containing versions of discontinued or reformulated products are likely to be on the market until retail supplies have been exhausted, so check labels carefully for ingredients. However, the only way to be certain a product no longer contains DMAA is through laboratory testing.
