How Late Is Too Late To Take Pre-Workout Supplements With Stimulants

Depending on the dosage of caffeine and other stimulants in the pre-workout you are taking. You will want to ensure you take these pre-workouts hours before laying your head on the bed.

A general rule of thumb is that you want to make sure there are at least 6-8 hours from consuming caffeine and other stimulants to when you want to go to bed.

So for example, if you plan on heading to bed around 10 p.m. You’ll want to make sure you’ve drank your pre-workout by 2 p.m.

This will ensure your body has ample time to let the stimulants run their course through your body.

Why You Can’t Sleep After Taking Pre-Workouts

The reason you can’t sleep after taking a pre-workout supplement is most likely because of these reasons:

  • You are taking pre-workout with high amounts of stimulants
  • You are taking these kinds of pre-workouts close to bedtime
  • Your tolerance to caffeine and stimulants is very low

These are the 3 main reasons you most likely can’t sleep after a pre-workout if you want to take advantage of pre-workout at night but also want a good night’s rest.

Then I suggest finding a pre-workout supplement without any stimulants.

Switch to a Stim-Free Pre-Workout Supplement

Your best bet when taking pre-workout at night is to switch to a stim-free pre-workout. Taking a stim-free pre-workout will help you fall asleep if you have had trouble sleeping with regular pre-workouts.

You will still get all the added benefits of increased blood flow, increase in exercise performance, delayed muscle fatigue, and muscle pumps without the boost in energy from the stimulants.

So this is the perfect solution for you if you need to do an evening workout because of your schedule.

Try To Take Pre-Workout In The Mornings

If you are a fan of taking pre-workout supplements with stimulants. Then your best bet to take pre-workout is either early in the morning or the latest I would recommend is at least early in the afternoon around 2 pm-3 pm if you want to get to bed by at least 10 pm.

This schedule is your best bet if you still want all the benefits of regular pre-workout supplements to fulfill your high-intensity exercise.

How Long Does A Pre Workout Supplement Last

This will depend on a wide variety of factors like:

  • The amount of caffeine within the pre-workout
  • Are there any other stimulants in the pre-workout supplements you are taking
  • You’re tolerance to ingredients

Every pre-workout supplement has its own blend of unique ingredients. But typically the effects of a pre-workout can last for 2-4 hours.

So I’ll do my best to cover the rest of the questions I’ve seen about how you can fall asleep and still take pre-workout at night.

How Long Does Pre-Workout Last Before Bed

The effects of pre-workout typically can last 2-4 hours. But the half-life and how long it takes your body to process stimulants can take up to 6-8 hours.

So even if you do not feel the effects of the pre-workout at night. Taking pre-workout too close to bedtime can still affect your sleep quality.
