Stimulants are common (and potentially problematic) ingredients in dietary supplements such as pre-workout and weight-loss products. But do you know how to tell if your dietary supplement product actually contains a stimulant? OPSS has some answers. Check out the OPSS FAQs about why stimulants are a problem and how to identify them on labels, both of which link to our list of “Stimulants found in dietary supplements.”
And while you’re there, visit our other OPSS FAQs, where you’ll find information about specific stimulant ingredients such as DMAA, DMBA, BMPEA, yohimbe, and synephrine. We also have several FAQs about caffeine, probably the most common stimulant.
If you’re feeling stressed, don’t rely on liquid relaxation products to relieve your tension. While energy drinks are promoted to give you an extra boost, relaxation drinks* are marketed to do just the opposite and help you, well, relax. These products commonly contain the amino acid theanine, as well as several different plant-based ingredients. But the science doesn’t support the use of relaxation drinks to decrease stress or anxiety, and consumers should be cautious of two ingredients: kava and melatonin. Bottom line, if you’re feeling stressed, try to identify the cause, and then use stress management strategies backed by scientific evidence. Read more here.
Your body makes 5-HTP, but it can also be made in a lab and used in dietary supplements. Products containing 5-HTP are marketed to help with a number of health conditions, including appetite control and depression. Do they work? Read the Operation Supplement Safety (OPSS) FAQ on 5-HTP to find out.

Using your military Pro Mask or other commercial mask device as a method of respiratory muscle training (RMT) isn’t going to prepare you for higher elevations. Increasing the strength of your respiratory muscles which help you breathe—your diaphragm and the muscles between your ribs—will improve aerobic fitness, especially for long-duration tasks.
RMT can be achieved through whole-body aerobic exercise, upper-body strength conditioning, and some commercial RMT devices. Studies show that RMT slightly improves performance in those who are already aerobically fit (e.g., military personnel). It offers somewhat more benefit for those less fit or with chronic conditions.
Your Pro Mask was made to protect your lungs, eyes, and face from chemical and biological agents, radioactive particles, and battlefield contaminants. It doesn’t create enough airflow resistance to help improve aerobic capacity. In addition, it wasn’t designed as exercise equipment. There is no scientific evidence that suggests using commercial masks at normal altitudes will improve your performance at high altitudes. Read more about the U.S. Army Research Institute of Environmental Medicine’s (USARIEM) review of Pro Masks and commercial products for exercise training. Check out HPRC’s take on using high-altitude masks and improving work performance at higher elevations.
Running is one of the simplest forms of exercise—just throw on your shoes and head out the door. But there are a few simple things you can do to ensure your run is safe too:
- Carry identification. Bring some form of identification with you. There are various types of wristbands and shoe tags to provide emergency contact and medical information too.
- Stay visible. Wear a headlamp and/or reflective gear so drivers can see you when it’s dark out—even at dusk and dawn. Make yourself visible to oncoming traffic.
- Turn the music down. Music can be a great way to help you keep pace. But if your tunes are too loud, you may not be able to hear cars or people coming up behind you. Keep music at a volume low enough that you can hear what’s going on around you, or try wearing just one earpiece when you run.
- Grab a buddy. Running with a friend is a great way to keep both of you motivated and accountable. But when you do run alone, let someone know and share your planned route.
- Use the crosswalk and follow crossing signs. Drivers tend to be more aware of pedestrians near crosswalks because in many areas pedestrians (runners included) have the right-of-way there. If you’re running where there is a crosswalk, use it.
- Don’t assume a car will stop just because you’re in a crosswalk. Make sure the driver sees you, slows down, and allows you to safely cross the street.
- Run against street traffic. Sometimes it’s easier to run on the shoulder or in a bike lane. Remember to run against traffic (normally the left side of the road) so you can see the cars and the drivers can see you.
Stay safe and happy running!
Do you know what’s in your dietary supplement? In the case of supplements, ignorance isn’t bliss, and what you don’t know can put your health at risk. Performance Triad has created 2 videos highlighting the dangers of dietary supplements. In “The Dangers of Supplements,” Drill Sergeant David Cross talks about the consequences he dealt with from using supplements, including permanent liver damage. Also watch the Operation Supplement Safety App video to learn more about what goes into dietary supplements. You can download the OPSS app to get access right in your hands to information about thousands of dietary supplement products and ingredients. Please visit the Apps tab of HPRC’s Tools for the Warfighters to download the app.
Dietary supplements that claim to be “all natural” aren’t necessarily safe. The Food and Drug Administration (FDA) has issued 2 Consumer Updates warning consumers about “all natural” products for erectile dysfunction and imported dietary supplements.
According to FDA, supplements marketed as “all natural” sexual-enhancement products might be tainted with hidden drug ingredients. Some of these are the same active ingredients found in prescription drugs used to treat erectile dysfunction. Not only could you potentially be consuming multiple drug ingredients, you could be consuming them in amounts even greater than prescription doses. Either way, these types of products can put your health and career in danger. For more information, please read FDA’s Consumer Update on "'All Natural' Alternatives..."
Consumers should also beware of dietary supplements and nonprescription drugs marketed as “all natural” remedies for serious conditions such as cancer, HIV/AIDS, diabetes, or heart disease. “Natural” does not necessarily mean safe, and these products also can contain undisclosed chemicals or drug ingredients that can be harmful. FDA specifically warns consumers about imported products sold online or at flea markets, or swap meets. Please read FDA’s Consumer Update on "Some Imported Dietary Supplements..." to learn more.
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.

Stimulants can be dangerous to your health, especially in large quantities, but they’re what give energy drinks their “punch.” You may already know caffeine is a major stimulant found in energy drinks. But do you know that energy drinks often contain other stimulants? These can include “hidden sources” of caffeine (such as guarana, green coffee bean, green tea, and yerba mate), yohimbe, and synephrine (bitter orange).
Many energy drinks, however, aren’t labeled with the amounts of caffeine or other stimulants in them. Some or all of these ingredients are often part of “proprietary blends,” so it’s impossible to determine from the label the exact amount of each ingredient you would be taking. Furthermore, energy drinks might be mislabeled or marketed as sports drinks, causing even more confusion.
Remember, stimulants come in many different forms, so Operation Supplement Safety (OPSS) put together a list of stimulants found in dietary supplements to help you identify these potentially harmful ingredients. And to help you understand what’s in your energy drink, check out the OPSS infosheet on energy drink labels, which includes helpful notes about ingredients.
