Creatine Before or After a Workout: Does Timing Actually Matter?

The Short Answer

It’s really a matter of when you’re going to be able to take your creatine. Before you train, after you train, with your breakfast, at bedtime, it’s all sufficient and leads to the same result. Let’s go through the evidence.

What Does the Science Say About Creatine Timing?

Some claim that taking creatine before training increases performance and others that taking it after improves recovery. The truth is that the evidence is weak in both directions.

According to a review conducted by Ribeiro and colleagues, in 2021, there is a lack of strong evidence to suggest that creatine should be taken before a workout. In fact, their review concluded that timing creatine around workouts is “currently not supported by solid evidence.” [Source: Ribeiro et al., 2021]

That’s not a fringe opinion. A comprehensive review by Antonio and colleagues in the Journal of the International Society of Sports Nutrition confirmed Ribeiro’s conclusions regarding timing and noted that total daily intake of creatine is significantly more important to results than when you take it.

The One Study That Everyone References and What It Really Shows

When researching online about the optimal timing for creatine consumption, you’ll often come across references to a study done by Antonio and Ciccone in 2013 comparing the effects of creatine dosing immediately prior to a resistance-training session versus immediately after. The post-exercise group demonstrated slightly greater improvements in lean body mass and strength.

Looks great, right? Until you dig deeper. The study included only 19 participants, ran for just four weeks, and found no statistically significant differences between groups. Therefore, the observed advantages could just as easily have been due to chance rather than being caused by a timing effect.

So, the strongest science-based argument for post-exercise dosing is one relatively short, low-participant-count study with statistically insignificant results. Not exactly a foundation to build your supplement routine on.

Why Timing Doesn’t Matter Much: How Creatine Works

In order to understand why timing plays such a small role in how effectively creatine works in your body, you must first understand how it works. Unlike caffeine or other pre-workout products, which provide a rapid increase in energy availability, creatine works by gradually replenishing phosphocreatine stores in your muscles over several weeks. Think of creatine as adding fuel to a gas tank. Once your tank is sufficiently filled, your muscles have a larger pool of phosphocreatine available to regenerate ATP during high-intensity efforts during training.

This saturation process takes roughly 2-4 weeks at a standard dose of 3-5 g per day (or about a week if you use a loading protocol of 20 g per day). Once your muscles are saturated, they stay saturated as long as you keep taking your daily dose.

Your muscles do not care if the day’s dose came 30 minutes before your workout or 30 minutes after, all that matters is that you don’t miss it entirely. Missing some doses here and there is not a huge deal, as emptying your stores takes time, as it does to fill them up in the first place, but try not to make it a habit.

Does Taking Creatine with Food Make a Difference?

As it turns out, there is one aspect of timing related to creatine supplementation that has slightly stronger evidence backing it up: taking creatine along with carbohydrate-rich foods and/or protein can enhance the rate at which your body absorbs creatine into muscle tissue. This occurs because insulin stimulates your muscle cells to take up creatine.

It doesn’t mean you need to load up on carbs and proteins with each dose. You can simply consume your typical meal or take it with your post-workout shake and that’s all.

If you work out while fasting, then you can also take your creatine on an empty stomach. The potential loss in absorption is very small and unlikely to affect your long-term results.

Should You Be Doing a Loading Phase with Creatine?

We touched on this briefly above, but since this area gets discussed quite frequently, it’s worth mentioning again. A loading phase usually consists of 5-7 consecutive days using 20 grams per day (usually split into 4 x 5 gram doses), after which you drop down to 3-5 grams per day for maintenance.

While loading will get you saturated faster (about 5-7 days vs 3-4 weeks), ultimately everyone reaches the same level of muscle creatine saturation by the end of the fourth week.

Our stance is that while loading works, it is unnecessary. If you really want to save some time or are impatient, go for it. Otherwise, keep it simple, just take 3-5 grams daily and allow saturation to happen. Either way, the end result will be the same.

So When Should You Take Creatine?

Pick a time that you can commit to taking every day without fail. Consistency beats optimizing. The ideal time for you to take creatine is whatever time you can consistently remember to take it.

If you want to optimize within those constraints:

• With a meal: there may be a slight boost in uptake due to the presence of insulin
• Post-workout with your recovery shake: easy to remember and pairs well with your protein powder
• Same time every day: even on rest days, continue taking it

What you should NOT do:

• Skip days because you forgot to take it during your “optimal window”
• Worry excessively about whether you took it twenty minutes before your workout or forty minutes after your workout
• Cycle on and off creatine (the science hasn’t shown benefits from cycling)

Common Concerns About Creatine Timing

Some individuals avoid consuming creatine prior to training due to concerns about gastrointestinal distress (such as bloating) occurring during their workout. For a small percentage of users, especially at high doses, this concern is valid. For anyone experiencing this issue, post-workout or with a later meal is an obvious solution.

Other consumers have expressed similar worries regarding creatine and water retention. As mentioned previously, creatine does lead to increased fluid retention within your muscles, this is part of how it functions. But this effect occurs regardless of when you take it and generally corresponds to approximately 1-2 kilograms of retained water weight during the initial weeks of supplementation. This is intramuscular fluid retention, not subcutaneous bloating.

The Bottom Line

The research is clear: total daily intake of 3-5 grams of creatine monohydrate, consumed regularly, is what generates results. Take it whenever works best for your schedule. Consuming it with a meal offers some slight advantage over taking it without. If you regularly drink a post-workout protein shake, adding it there is a solid option too. But honestly? Just take it every day, whether in powdered form or gummy form, and quit obsessing about when.
