Dietary supplements: What’s in them for you?

HPRC’s new Dietary Supplement Classification System offers information to help you decide whether a dietary supplement can help you reach your performance goals or whether it may have side effects you want to avoid.

What do you put in your body to boost your performance, increase your energy, shed pounds, build muscle, or otherwise supplement your diet? What’s in that drink, pill, or powder? What will it do for you? What will it do to you? Is it worth the risk?

More and more Warfighters are taking dietary supplements, most without being fully informed that some of the ingredients could have harmful side effects. HPRC has just unveiled its Dietary Supplement Classification System to provide this kind of information and help you make informed decisions about a particular supplement. To start exploring this new resource, visit HPRC’s new web pages. If you have a question, contact us via “Ask the Expert.”

DMAA-containing products in question

HPRC offers a list of products containing DMAA to help you make informed decisions in buying dietary supplements.

Dietary supplement products containing DMAA have been temporarily removed from military stores by the AAFES, but they are still available on the public retail market. HPRC has prepared a list of many of these products to help you watch for them if you are considering the purchase of dietary supplements. DMAA is found most commonly in products sold for bodybuilding or weight loss, but it can also be found in other performance-enhancing products, as well as in recreational party pills. The list also includes other names for DMAA that may be found on product labels. To download the list, go to the Dietary Supplements Resources page under the “Resources” tab, or just click on this link to directly access “Dietary Supplement Products Containing DMAA.”

More on Jack3d and OxyElite Pro

Jack3d and OxyElite Pro contain the ingredient DMAA, but recent findings do not support claims that it is a “natural” derivative from the geranium plant. It’s another story of “buyer beware.”

HPRC recently wrote about “The Lure of Jack3d” and answered a “Question from the Field” about OxyElite Pro. Jack3d is marketed as a pre-workout supplement and OxyElite Pro is marketed as a fat-burner product. Both contain the ingredient 1,3-dimethylamylamine (DMAA). Since we last wrote about both products, there have been new reports about DMAA.

Makers of Jack3d and OxyElite Pro claim that DMAA is a “natural constituent” of the geranium plant. DMAA was originally patented as a drug in the U.S. by Lilly in the 1940s. Since then, it has been identified on many product labels (especially on sport, energy, and weight-loss products) as being derived from geranium oil, stem, or extract, but review of the scientific literature has not substantiated this claim. To date, there is no credible scientific data that establishes the presence of methylhexanamine in geranium. Recently, the American Herbal Products Association announced that products containing DMAA (which can also be seen on labels as 1,3-dimethlypentlyamine, methylhexaneamine, or MHA, in addition to 1,3-dimethylamylamine) should be labeled as such and not as geranium oil or any part of the geranium plant. Health Canada has clarified that DMAA is a drug and must go through appropriate drug approval processes before it is used in any product. The United States Anti-Doping Agency (USADA) has long warned athletes about dietary supplements and more recently about the inclusion of methylhexaneamine in products under the guise of “geranium”; USADA has recently issued an advisory to athletes. There are questions about whether DMAA may be legally included in dietary supplements, since there is no credible evidence that it is present in geranium and it has not gone through the New Dietary Ingredient notification process with the Food and Drug Administration. Therefore, caution is advised when considering whether to use a product that contains this ingredient. Please be aware that such products may be sold in large retail nutrition outlets and on the Internet.

Athletes are advised to avoid consuming supplements that contain the prohibited stimulant methylhexaneamine, also known as DMAA.

The United States Anti-Doping Agency (USADA) has issued an Athlete Advisory regarding methylhexaneamine, a prohibited stimulant. After reports that many athletes have tested positive for this stimulant, USADA is advising athletes to be cautious about taking supplements with methylhexaneamine, also referred to on labels as 1,3-dimethylamylamine (DMAA), dimethylpentylamine (DMP 4-methylhexan-2-amine), Geranamine, and geranium oil, extract, or stems and leaves.
