Reporting adverse events associated with dietary supplement use

Reporting adverse events from dietary supplement use is essential for determining the safety of available products and ingredients.

Many adverse events associated with dietary supplement use go unreported. HPRC has developed one page information resources on how to report adverse events. Warfighters and their families can follow the directions for reporting adverse events to MedWatch (FDA) and Natural Medicines Watch. In addition to these sites, Health care providers can follow step by step directions for reporting via AHLTA.

Consider the side effects before using Apidexin.

Before trying to slim down with weight loss supplements, consider the potential side effects. Some could seriously impact your health.

Apidexin is a weight-loss supplement that contains vitamin B12, chromax (a form of chromium), and a proprietary blend of various ingredients. One of the ingredients is guggul, which has been associated with side effects such as headaches, nausea, vomiting, diarrhea, skin reactions, and more. Other ingredients in Apidexin with known side effects are Irvingia gabonensis and DiCaffeine Malate. Both been associated with headaches and difficulty sleeping, and the latter also can increase heart rate and raise blood pressure. And keep in mind that there’s no data on how all of these ingredients might act together. For more detailed information, read HPRC’s Answer to a recent question about the side effects of Apidexin.

Why is vitamin C good for me?

HPRC Fitness Arena: Nutrition, Total Force Fitness
Vitamin C is essential for your body to protect itself from various sources of damage, so make sure you get the recommend daily amounts.

Vitamin C is a nutrient found in citrus fruits, broccoli, strawberries, cantaloupe, tomatoes, other fruits and vegetables, as well as fortified 100% fruit juices. Among other things, it acts as an antioxidant, helping to protect cells from damage caused by free radicals, which your body produces as it converts food into energy. How much you need depends on your age. For the average recommended daily amounts and other information about vitamin C, read the Office of Dietary Supplements Quick Fact Sheet.

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.

For more information, read the USADA Athletic Advisory.
