Dietary supplements containing stimulants can negatively affect your heart and increase your risk of an adverse event. Stimulants such as caffeine, yohimbine, and synephrine can cause increased or irregular heart rate and high blood pressure and have been associated with chest pain, stroke, and heart attack. In addition, ingesting stimulants before or during exercise can further increase your risk for such heart problems and lead to potentially worse outcomes.
If you are considering a dietary supplement, it’s important to read the product label carefully, especially if you have a heart condition. There are many different stimulants used as ingredients in dietary supplements, and often products come with a warning. Moreover, stimulants are sometimes contained in a proprietary blend, so you can’t tell from the label exactly how much of each ingredient you would be taking.
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.
Prescription stimulants can improve attention and alertness, and doctors prescribe them for people with Attention Deficit Hyperactivity Disorder (ADHD) or excessive fatigue. Used improperly and without the supervision of a health provider, these drugs have serious side effects. Some people misuse and/or become addicted to them. Learn more in HPRC’s “Stimulant drugs: use and misuse.”
A Military Times article reports on a recent study of more than 30 of the most popular dietary supplements (in capsule form) sold on military bases analyzed to determine their caffeine content. Of the 20 supplements that listed caffeine as an ingredient on their labels, six did not specify the amount. These same six contained high amounts of caffeine (210-310 mg per serving)—three or more times the amount permitted by law in soft drinks. Five others revealed significantly different amounts—some more, some less—than the quantity stated on the product label.
Consuming too much caffeine can result in health issues. And if you don’t know how much is in the supplement you’re taking, it could be easy to overdo it if you also drink coffee or energy drinks. Visit the Operation Supplement Safety (OPSS) FAQ on caffeine for additional information.
