Just as the name suggests, pre-workout supplements are designed to be taken before you hit the gym. But how long do they last in your system? And more importantly, what kind of effects can you expect while they’re still active?
The answer to the first question depends on the ingredients in the supplement. Generally speaking, though, pre-workouts will start working within half an hour and last for a few hours. The effects you experience will vary depending on the type and amount of stimulants in the mix.
Most pre-workouts contain some combination of caffeine, guarana, and/or yerba mate. These substances stimulate the central nervous system and can cause increased heart rate, anxiety, jitters, and other side effects. For the most part, these effects wear off within a few hours.

However, some people can be more sensitive to stimulants than others. If you’re new to pre-workouts, start with a low dose and work your way up gradually. And if you ever experience any uncomfortable side effects, stop taking the supplement immediately and consult your doctor.
Pre-workouts are designed to help you achieve your fitness goals, not sabotage them. So make sure you understand how they work before you start taking them. And always consult a healthcare professional if you have any questions or concerns.
