It is estimated that more than 20,000 Americans go to an emergency room every year for reasons related to dietary supplements such as allergic reactions and adverse events, according to a government study. Adverse events can result from ingredients in dietary supplements themselves or from drug-supplement interactions and can have serious side effects. Among adults, common complaints include chest pain and increased heart rate and are often associated with weight-loss products, energy products, bodybuilding products, and sexual-enhancement products.
Before taking any dietary supplement, talk to your doctor and be an informed consumer. It can prevent a health scare and even could save your life! For more information, please visit Operation Supplement Safety (OPSS), including the OPSS High-Risk Supplement List. And for more information about this study, read this article from MedlinePlus.
Many people take dietary supplements and medications together as a part of their daily health regimen, but few are aware of the potential for harmful interactions between prescription drugs, over-the-counter drugs, and dietary supplements. To help you learn more about these types of interactions, the National Center for Complementary and Integrative Health (NCCIH) created an interactive web resource that includes information about how supplements can change the effectiveness of your medications and how to work with your healthcare provide to make sure you’re taking them together safely. And for more information, please read HPRC’s Supplements and medications – What’s the problem?
SARMs, or “selective androgen receptor modulators,” are experimental drugs that are illegal for use in dietary supplement products, but they still can be found in stores and on the Internet. SARMs are most often found in products advertised to have effects similar to those of anabolic steroids.
Read the Operation Supplement Safety (OPSS) FAQ about SARMs to learn more, including the ingredient names used for SARMs that may appear on dietary supplement labels. And remember: FDA does not approve dietary supplements prior to marketing. For more information on FDA’s role with regard to dietary supplements, visit FDA Basics.
Cannabidiol (CBD) is a major chemical found in marijuana that may have beneficial effects on certain health conditions, but it’s still being tested as a new drug. However, FDA recently announced that products containing CBD cannot be sold as dietary supplements.

DMAA has been illegal as a dietary supplement ingredient for more than 2 years, but products containing this substance continue to be available. Many are still being produced (or produced again), and some are even new. That means it’s very important to read dietary supplement product labels carefully to make sure yours doesn’t contain this potentially dangerous ingredient. Not only could it be dangerous to your health, it could also be dangerous to your military career. DoD follows federal policy with regard to the use and possession of substances and products considered illegal.
Keep in mind, though, that pre-workout, weight loss, and other performance dietary supplements without DMAA also may not be safe for your health. In fact, FDA has already declared two DMAA “replacement” ingredients unsuitable for use in dietary supplements: DMBA and BMPEA. For more information, please visit these Operation Supplement Safety (OPSS) FAQs:
- Is DMBA the same thing as DMAA? Why were these products pulled from stores on military base?
- What is BMPEA and why has FDA issued a warning about it?
- Has DMAA been banned for use by military personnel?
And please visit the newest update of “Dietary Supplement Products Containing DMAA,” which lists DMAA-containing products past and present.
It’s cause for concern: Approximately 30% of teens consume energy drinks on a regular basis. Energy drinks provide no nutritional benefit and can actually pose health risks to adolescents, including increased heart rate, high blood pressure, anxiety, digestive problems, sleep disturbances, dehydration, and even death. Teens who consume energy drinks are also more likely to engage in unhealthy behaviors such as drinking more sugar-sweetened beverages, smoking cigarettes, and using drugs and alcohol.
Many of the negative effects associated with energy drinks are due to the large amounts of stimulants in these beverages. Their caffeine content can range from 50 to more than 500 mg per can or bottle. The American Academy of Pediatrics recommends that children and teens:
- consume no more than 100 mg of caffeine per day (equal to about 2 cans of caffeine-containing soda or one 8 oz. cup of coffee) and
- avoid energy drinks altogether.
However, the amount of caffeine teens consume from energy drinks is trending upwards, in part due to heavy marketing with celebrity athletes. Be sure to talk to your teens about the potential problems associated with energy drinks, and make sure they don’t confuse them with sports drinks.
Whole foods, not dietary supplements, should be your first choice for protein. Protein supports muscle growth and repair. People often turn to protein supplements (such as whey, casein, and soy) to optimize those effects, especially after a workout. Whole food protein sources such as lean meats, fish, dairy products, legumes, nuts, and seeds are just as effective (in some cases more effective) than protein supplements. Whey protein products can be an acceptable, convenient, and efficient way to deliver protein when your needs are greater or when normal dietary sources are not available. If you are using protein supplements, be sure to choose a product that has been third-party evaluated for its quality. Read more here.
The Food and Drug Administration (FDA) is again warning about the dangers of powdered pure caffeine. At least 2 deaths (both teenagers) were associated with it in 2014, yet it continues to be sold, primarily in bulk online. FDA recently sent warning letters to 5 distributors of pure powdered caffeine, warning about potential serious health effects. FDA notes that it’s difficult to determine the difference between a safe amount and a toxic amount but that one teaspoon is roughly equivalent to 28 cups of coffee. For more information, read FDA’s update and HPRC’s 2014 article.

Conventional foods and dietary supplements follow different rules when it comes to labeling, but the difference between the two isn’t always black and white. Such is the case with protein powders. If you look closely at various protein powders, you may notice that some are labeled with Nutrition Facts (required for foods), while others have Supplement Facts (required for supplements). So are protein powders conventional foods or dietary supplements? Read more in our OPSS FAQ on protein powder labels.
