Should You Take Creatine Before Bed? (Explained)

Updated: Oct 12

TL;DR: Taking creatine before bed doesn't seem to have any significant drawbacks or advantages. Though, there is an optimal time to take creatine.

Creatine is a great supplement for improving exercise performance, including strength, muscle growth, and endurance.

However, some people believe that taking creatine before bed could have adverse effects, such as weight gain or keeping them awake.

In reality, taking creatine before bed is perfectly fine, you will still reap the benefits, and because it's not a stimulant it will not keep you awake, in fact it may even help improve your sleep.

Although it's fine to supplement with creatine before bed, it's not the optimal time to take creatine.

In this article, I will explain if you should take creatine before bed and the optimal time to take it.

What Is Creatine?

Creatine is a naturally occurring substance found in the cells of your body. It is present in higher abundance in muscle cells, accounting for 95% of the total, with the remaining 5% found in the brain, liver, and kidneys.

The amino acids glycine and arginine may also be used by the body to make creatine.

Creatine may also be taken in the diet, either as a supplement or through meals like meat. This supplement is popular among gym goers, bodybuilders, and other athletes.

If you take creatine, your phosphocreatine stores will increase. Phosphocreatine is a form of stored energy that helps your body produce ATP, which is your body's main energy source.

When your body has more ATP, your muscle performance improves. Many other processes occur when creatine is consumed, some of which may contribute to muscular development and strength.


Supplementing with creatine can provide multiple benefits, such as the following.

  • Enhanced strength and performance

  • Increased muscle mass

  • Improved brain health

Creatine has also been proven to enhance strength and workout performance substantially.

In fact, adding creatine to a resistance training regimen enhanced strength by about 8%, weightlifting performance by around 14%, and bench press one-rep max by up to 43%, according to one study. (6)

Creatine has been proven to help with both long-term and short-term muscle development. It has also been selected as the most helpful dietary supplement.

Creatine supplementation to a resistance training regimen enhanced muscle growth and leg strength substantially in a 14-week trial of older people. (7)

Creatine supplementation resulted in a 70% decrease in tiredness and a 50% reduction in dizziness in children with traumatic brain injury during a six-month trial. (8)

It may also help the elderly and those at risk of neurological disorders, according to human studies. (9)

Should You Take Creatine Before Bed?

As I mentioned earlier, it is perfectly fine to take creatine before bed. You will still gain the benefits of creatine supplementation such as improved strength, muscle growth, and endurance.

Creatine does not affect your sleep in a negative way, in fact some preliminary studies suggest that supplementing with creatine may even improve some aspects of sleep. (1, 2)

Some people also believe that taking creatine before bed will also cause them to gain weight or fat, it is true that creatine can cause water retention, but it's not true that it causes fat gain. (3)

Now the myths are out of the way, is there any benefit to taking creatine before bed?

There isn't any research on this matter, I also don't have any theory behind why taking creatine before you go to bed would make any difference. Therefore, tasking creatine before bed is perfectly fine but not the optimal way to take it.

Optimal Time to Take Creatine

Fine-tuning an optimising the time you take creatine is not as important as getting a full daily dose (3-5 grams), meaning providing you consume that dosage, it doesn't matter what time you take it.

With that being said, studies have indicated that consuming creatine before and after a workout may enhance its effectiveness. (4)

Research suggests that taking creatine immediately post-workout is the most optimal time to take creatine. (5)

The most optimal time to take creatine is pre or post-workout, preferably immediately post-workout. Though, the difference is small, providing you reach your complete daily dosage of 3-5 grams, it's not a crucial factor.

Whatever time suits you in the day, whether that's when you wake up, at lunch, pre-workout, before bed, etc, is perfectly fine.
