HPRC’s DMAA list updated again

HPRC’s list of DMAA-containing dietary supplement products has just been updated, including more products found to contain DMAA and many more that are no longer being produced.

The latest update of HPRC’s list of DMAA-containing dietary supplement products is now available online. The list now indicates more than 80 products that have been removed from the market or reformulated to exclude DMAA, or that no longer include DMAA in the list of ingredients on the label and/or manufacturer’s website. In addition, DMAA-containing versions of recently removed/reformulated products are likely to still be on the market until retail stocks have been depleted, so be sure to read labels carefully. However, the only way to determine if DMAA is no longer in a product is through laboratory testing.

HPRC has begun to hear from manufacturers and distributors about changes to their products to exclude DMAA. Please note that products now seem to change almost daily, while the list is updated about every six weeks. We welcome input to help us keep track of changes.

Alert: Dendrobium for performance?

A new dietary ingredient—a stimulant—has emerged in dietary supplement products marketed to boost athletic performance.

A new dietary supplement ingredient, dendrobium, is appearing rapidly in dietary supplement products promoted to boost athletic performance. According to the Natural Medicines Comprehensive Database, manufacturers claim that dendrobium is a natural source of the stimulant phenylethylamine, but some researchers say that phenylethylamine doesn’t occur naturally in dendrobium. Phenylethylamine is a stimulant, with effects similar to those of amphetamines. At this time, the safety of dendrobium is unknown, so users should be aware that products containing this ingredient might be unsafe, particularly when used in combination with exercise.

Operation Supplement Safety (OPSS) is about to launch this summer and will answer many of your questions about Dietary Supplements. Watch for HPRC’s announcement coming soon.

 

Tainted products widget

Updated DMAA list available

 HPRC’s list of DMAA-containing dietary supplement products has just been updated.

The latest update of HPRC’s list of DMAA-containing dietary supplement products is now available online. Six more products have apparently been removed from the market; one has been added to the list because the fact that it contains DMAA is stated only on the product label, not on the manufacturer’s website.

Stars and Stripes reports: Army study on DMAA will continue

The Army will continue its own study on the effects of DMAA even after the FDA sent warning letters to marketers and distributors of dietary supplement products with DMAA.

Following in the wake of the Food and Drug Administration’s warning letters to manufacturers and distributors of dietary supplements containing DMAA, the Army announced that its own study on the effects of DMAA on soldiers will continue. Read about the announcement and more in the recent Stars and Stripes article. For more information about the FDA’s action, you can read HPRC’s post, which also includes a link to the FDA news release.

FDA Warns Companies about DMAA Safety

Marketers and distributors of products containing DMAA warned by FDA.

The Food and Drug Administration (FDA) sent warning letters to manufacturers and distributors of dietary supplements containing 1,3-dimethylamylamine (DMAA) due to lack of safety evidence provided before marketing. The FDA states that information about the safety of DMAA as a dietary supplement ingredient has not been identified. For more information, see the FDA News Release and HPRC’s latest on Dietary Supplement Products Containing DMAA.

DMAA list updates

HPRC has again updated its list of DMAA containing products. The latest news includes New Zealand’s ban on DMAA-containing products.

The latest news on DMAA includes the New Zealand government’s ban just placed on DMAA-containing products. DMAA has already been declared a drug in Canada and is banned by the World Anti-Doping Agency, the United States Anti-doping Agency (USADA), collegiate sports teams, and most professional sports teams.

HPRC has again updated its list of DMAA-containing dietary supplements, including a number of additions as well as some products that have been discontinued or reformulated. The additions mostly represent lesser-known products that have been around a while, but surprisingly there are a couple new products too. And we have added two new “aliases” to the list of other names for DMAA. To download the list, click on this link to “Dietary Supplement Products Containing DMAA.

Senator Durbin urges FDA to investigate energy drinks

Senator Dick Durbin has asked the FDA to investigate the caffeine content and other ingredients in energy drinks due to serious concerns about their safety.

HPRC has written about energy drinks and their possible adverse health effects; these drinks continue to be in the news following the death of a teenage girl due to caffeine toxicity from drinking two Monster energy drinks. Senator Dick Durbin has now urged the Food and Drug Administration (FDA) to investigate energy drinks, specifically to regulate caffeine in these drinks (caffeine content in colas is already regulated) and determine whether other ingredients contained in them are safe. Read the press release and Senator Durbin’s letter to FDA.

Introducing OPSS: Operation Supplement Safety

Watch for new educational materials about how to determine if a dietary supplement is relatively safe or not.

Do you buy dietary supplements when you want to lose weight, improve your performance, or give yourself a boost to get through a long day or hard workout? Then watch for this soon-to-be-released service-wide educational campaign by the Department of Defense in collaboration with the Human Performance Resource Center. Operation Supplement Safety (OPSS) will help Warfighters and their families make informed decisions when choosing dietary supplements. See HPRC’s new OPSS link for an introductory article on supplement safety.

Dietary supplements and drug testing

Want to know if your dietary supplement or prescription drug product will affect your drug test? Consult with DoD laboratories for help.

HPRC has received a number of questions about whether dietary supplements—especially those used for bodybuilding and weight loss—could result in a positive result on military drug tests.

Military drug testing begins with urine, which is first screened and then followed by additional tests depending on the outcome of the screen. You can get extensive information about DoD’s drug policy and drug testing from the Drug Demand Reduction Program (DDRP), including military testing. And for answers about the potential effects of specific dietary supplements on drug screening tests, you can contact your service’s military drug-testing laboratory by phone or email at:

Positive urinalysis results due to dietary supplement use can occur because products on the market may contain undeclared drug ingredients—that is, controlled substances that are not stated/listed on the product label. More information can be found in the FDA Consumer Update There you will also find information about how to get updates about products FDA has identified as tainted. There is no way to know if a particular supplement contains an undeclared drug without laboratory testing, but FDA does keep track of such products once identified through its MedWatch program.

The Department of Defense (DoD) currently has no formal policy on the use of dietary supplements and no list of either banned or safe supplements. For more on this topic, see Operation Supplement Safety’s (OPSS) FAQ “Is there an all-encompassing list of dietary supplements that are banned or illegal for use by military personnel?”
