When consuming your pre-workout before a workout, you’ll start to feel the effects within minutes, but that also depends on the type of supplement you’re consuming.

If it is a caffeine-based supplement, it may take 30 minutes, but that is also true for pre-workouts based on creatine and beta-alanine. It depends on how your body handles the ingredients.

For it to have an effect, it usually takes 30 to 60 minutes for the “peak concentration” to reach your blood.

Caffeine’s effect can last between 3 and 5 hours; even after hours, some of the caffeine you consume would be in your system.


For beta-alanine to kick in, a window of 20 to 30 minutes is required.

But if you mismanage the use of beta-alanine, as in consuming it in small doses or using it for an extended period, you may not be able to experience its after-effects.

For the peak effects of L-Arginine to be felt, a study states that 1 hour is to be experienced.

When To Take Pre-Workout And When Not To?

To experience the full benefits of the supplements, one must consume the pre-workout supplement approximately half an hour before the workout.

It’s better to take pre-workout supplements early rather than late, as the effects need some time to kick in for one to achieve the most benefits.

The ideal time to consume pre-workout is exactly before you start your workout, 20-30 mins before your training.

If you wish to avoid being pumped up throughout the night, be cautious about how late you take your pre-workout.

If you consume your pre-workout too near tonight, it may disturb your sleep, causing an alteration in your regime.

This isn’t healthy when the only reason you consume the pre-workout is to gain energy. Always follow as instructed on the packaging and consult a doctor before use.

The pre-workout solution kicks in depending on the state of the body and the ingredients of the pre-workout, mostly the ingredient’s half-life.

For example, if a person is less responsive to stimulants, then that person would probably experience the effects of the supplements during the next 6 or 7 hours, as it may range from 45 minutes to 3-6 hours.

But if a person is responsive to the stimulants, they may feel the effects of the stimulants for more than 6 hours.

Factors such as body weight and the amount of caffeine in pre-workout supplements are also important.

So to put it simply, pre-workout remains in your system for 6 hours at most.
