The Best Time To Take Creatine

What is Creatine?

Creatine is one of the most popular workout dietary supplements. Those who participate in sports, bodybuilding, or regular fitness routines experience many great benefits from consuming creatine.

Creatine is an amino acid derivative that we consume in red meat and seafood [1, 2]. Our bodies are also able to synthesize creatine in the kidneys and liver from amino acids glycine and arginine [1, 2]. Our bodies have creatine stores, where creatine is stored until it is needed. 95% of creatine is stored in skeletal muscle, while the remaining 5% is stored in the brain, liver, kidneys, and testes [2, 3].

Women’s creatine stores are slightly different than men’s due to the difference in body size and natural muscle mass, but the exact ratios are unknown [4].

Common Benefits of Creatine Supplementation

Athletic Performance and Muscle Strength

The main reason that people supplement creatine is to improve their athletic performance and increase muscle strength.

ATP (adenosine triphosphate) is the energy source that muscles use to contract during exercise [1, 4, 5]. After ATP is used for muscle contraction, ATP lets go of a phosphate and becomes ADP (adenosine diphosphate) [4, 5]. Since muscles need a continuous supply of ATP for repetitive muscle contractions, the body can resynthesize ATP by combining stored creatine with a phosphoryl group [2, 4, 5]. For explosive, high-intensity exercises, creatine stores may become depleted, which is where creatine supplementation comes in handy as it saturates the body’s creatine stores [2, 5].

Multiple studies show that creatine supplementation is effective in improving athletic performance and increasing muscle strength [1, 2, 3, 4, 6, 7, 8, 9, 10, 11]. Creatine supplementation can improve training tolerance, increase maximum effort, improve repetitive performance, improve endurance, and increase work capacity [1, 2, 3, 4, 6, 7, 8, 9, 10, 11].

Muscle Mass and Body Composition

Research shows promising evidence that creatine supplementation has the potential to increase muscle mass, as muscle strength and performance are improved [1, 2, 4, 6, 7, 8, 9, 10, 11].

Muscle mass increases are greater for men than women due to hormone differences [2, 7].

If you are concerned that creatine may make you gain weight, research shows that creatine does not cause weight gain [4, 7].

Exercise Recovery

Some research indicates that creatine supplementation before exercise may help protect muscle from injury and reduce the chances of muscle fatigue [2].

How Much Creatine Do I Need?

When you begin supplementing creatine, you should start with a loading phase. The loading phase consists of taking 5 grams (or 0.03 g/kg body weight) four times a day for approximately 5 to 7 days [2, 4, 12].

After you complete the loading phase, your muscles will be saturated, and you can continue supplementing a maintenance dose of 5 grams per day (or 0.03 g/kg body weight) [2, 12]. You can calculate how much creatine you need to take based on your body weight here: Creatine Calculator.

What Is The Best Time To Take Creatine?

Research is very limited on this topic, as only a handful of studies have been completed.

One study showed that creatine supplementation immediately before and after resistance training produced similar gains in muscle strength and muscle mass after supplementing for eight months [9]. However, when they compared results to the placebo group, they found that only post-exercise creatine supplementation increased lean body tissue mass and leg press strength [9].

Another study found that post-exercise creatine supplementation produced greater results in older adults, but they did not compare creatine supplementation to a placebo [9].

Most study results have limitations, as their participant groups are very small [10]. The most considerable study completed had 39 older adult participants who supplemented creatine and engaged in 32- weeks of resistance exercise 3 days a week [10].

They divided the participants into three groups: creatine supplementation pre-exercise, creatine supplementation post-exercise, and a placebo group, who took the placebo before and after exercise [10]. Both the pre and post-workout creatine supplementation groups had similar gains in strength, which were greater than the placebo group [10]. However, the group that supplemented creatine after their workouts experienced more significant increases in lean tissue [10]. But, there were no differences in the lean tissue gains between the pre-workout supplementation group and the placebo group [10].

The researchers concluded that the post-workout supplementation group experienced more significant grains because exercising increases blood flow in the skeletal muscle, which increases creatine transport in the muscles [10]. Another study found similar results in that post-workout creatine supplementation provided better results for recreational bodybuilders [11].

The most conclusive evidence points to post-workout supplementation being the best time to take creatine [9, 10, 11, 12]. However, the best timing is not precisely determined, and much more research needs to be done [12]. Most studies have only found that post-workout supplementation has increased lean mass, and research is lacking on the timing of creatine in relation to increases in strength or athletic performance [9, 12].

As mentioned, some researchers concluded that the reason post-workout creatine supplementation caused greater effects was because of increased blood flow in the muscle tissue after a workout, thus increasing the rate of creatine transportation [10]. Others have agreed that this may be the reason, but it is simply a theory that has not been studied [9].

The most recent research from 2022 suggests that the impact of timing on creatine supplementation may be dependent on the timing of creatine supplementation in combination with carbohydrate consumption [11]. Consuming creatine in combination with carbohydrates elevates creatine stores for a short-term duration [11]. Since this was not evaluated in previous research, the results of post-workout creatine supplementation being more beneficial are deemed weaker [11].

It is very hard to conclude the best time for creatine supplementation due to the limited amount of studies, which also had many limitations and did not account for all variables. Research shows that the timing of creatine supplementation, whether pre or post-workout, produces similar results that are close enough for it not to make a difference in overall effects.

FAQs

Wrapping Up

Overall, research points to post-workout creatine supplementation being superior to pre-workout supplementation for increased lean tissue mass, but much more research is needed on this topic for us to be able to state the optimal timing for creatine supplementation.

The good news is that no matter when you take creatine, you will experience benefits to some extent!

You can also rest assured that creatine supplements are generally a safe dietary supplement to take [1, 4]. Those who are pregnant, have bipolar disorder, kidney disease, or Parkinson’s disease should avoid taking a creatine supplement [1].
