When Is the Best Time to Take Creatine?


Considering Creatine?

Creatine is a fitness supplement that is somewhat controversial in the world of health and fitness. It’s the number one supplement for boosting exercise performance, and many body builders swear by it. It’s often associated with overly jacked gym bros, and has something of a varied reputation among those who are more focused on the overall health benefits of a good diet and exercise. If you’re considering creatine supplements as an addition to your exercise routine, it is worth knowing when to take creatine, what it is, and what its effects are before deciding on an answer to the question “when should I take creatine?”

Below, we’ll give you a brief introduction to creatine supplementation, explaining what it is and answering common questions such as “what does creatine do?”, “does creatine work?” and “is creatine bad for you?” before moving onto the big question of when you should take creatine in order to get the best creatine benefits for your work out routine.

What is Creatine?

Creatine supplements work by providing a high level of amino acids that your body can break down into creatine phosphate, a form of cellular energy that your body can use to feed your muscles during intense, explosive exercises such as HIIT routines, sprints, or heavy lifting bursts. Creatine supplements increase the amount of fuel available to your muscles, allowing you to keep that high level of power up for slightly longer reps.

Creatine helps your muscles to recover quickly between sets during exercise, which means that you can do more work in a single workout before running out of energy for your muscles. This means that you can work out longer and harder, leading to faster gains in muscle size and strength from working out.

Creatine has been known to boost performance in repeated sessions of intense heavy exercise since the 1970s. Soviet scientists discovered the benefits of creatine supplements, and used them to help maintain the USSR’s impressive performance in the Olympic games throughout the 1970s and 1980s.

Benefits of Creatine

The effects of creatine can vary somewhat between different users, as everyone’s body is a little different and the way you metabolize certain supplements can differ. In most cases, combining creatine use with regular weight training can slow down the loss of bone mass as your body ages, and can potentially reduce the risk of osteoarthritis, keeping your joints flexible and pain free.

Creatine also usually causes muscle fibers to grow faster when combined with resistance training and similar forms of exercise. This means that it can allow you to get a little bit more out of your work out routine, reducing the amount of rest you need during a  workout session. You still have to do the exercise, though; creatine isn’t some magic fitness pill you can take to build muscle without needing to work out!

Creatine has a couple of other benefits in addition to moderate boosts to exercise performance and muscle strength. These are useful benefits for anyone, not just people who work out a great deal. Sleep deprivation can be a major problem for many people, dragging your mental performance down and causing a much worse mood. These effects are partially due to a drop in creatine levels in the brain caused by sleep deprivation. Studies suggest that creatine supplements can actually help significantly with the decline in mental performance that most people experience when low on sleep, and can be just as effective as caffeine, but without the unwanted side effects and addiction problems!

Creatine side effects

There aren’t many side effects associated with creatine, and those that are known are actually fairly insignificant. Creatine supplementation can often lead to around 2 to 4 lbs of weight gain in the first week or so, primarily due to your muscles retaining water in order to increase growth. That’s nothing to worry about for most sports, although some sports that require a lower weight may find that it can be an issue. Combat sports where weight limits are placed on competition bands may have an issue with this, particularly if you’re normally on a weight threshold, while endurance cycling and running or swimming can find a drop in performance due to increased weight.

The added water weight tends to help your muscles to feel a little bigger, as this is where the water retention is concentrated, so it isn’t much of a problem unless you’re involved in a sport where weight limits are relevant to performance or competition.

There are reports of those who use creatine supplements experiencing a higher incidence of cramping and injury. The good news is that these claims seem to be pretty much unfounded. There hasn’t been a huge amount of research performed on this topic, but the few studies there have been indicate that there is no increased risk of cramping and injury from creatine supplementation.

The other major side effect of creatine that has been reported on a few occasions is an increased risk of kidney problems. This appears to be primarily complications with pre existing medical conditions, in which users who already have issues have developed further problems while taking creatine supplements. If you’re healthy and don’t already suffer from medical issues, there shouldn’t be much of an issue with taking creatine.

Creatine and diabetes

Creatine can have unwanted side effects if combined with diabetes medication, and can cause complications if taken by unmedicated diabetics. In general, it is recommended that diabetics avoid taking creatine at all, as it can cause a number of side effects and problems. Creatine can affect blood sugar levels, which must be carefully maintained and balanced by diabetics, and also significantly increases the risk of developing kidney and liver problems if taken by those who suffer from diabetes.

If you’re at all uncertain about taking creatine, talk to your doctor first in order to ensure that there are not problems with possible interactions between creatine and any other medication you may be on. If in doubt, you should avoid adding creatine or any other supplement to your routine.

How to use Creatine

If you’re just starting to take creatine, there are a couple of things that are worth remembering. The first is that it is generally recommended to start off with what’s known as a “loading phase”, in which you take higher amounts than usual (usually somewhere in the region of 20 grams) for a period of about five days. This loading phase quickly boosts the creatine content of your muscles with a high level of creatine supplementing, getting them all set up and ready for maximized exercise performance.

After a few days of this loading phase, you should cut down to a maintenance dose, usually of somewhere around 3 to 5 grams every day, in order to maintain this elevated level of creatine in your muscles.

When to take Creatine

Most people who use creatine supplementation like to take creatine pills or powder on days when they exercise, but there are three main options for when to take creatine powder or pills on those days. You can take it just before you start to exercise, just after you’ve finished exercising, or at some other time during the day. Alternatively, as a bonus fourth option, you can split your daily dose and take a little at a time at various times across the day.

A great deal of research has been done into finding out what the best time is to take creatine. There have been several scientific studies with reliably large sample sizes, giving solid scientific backing to the arguments about creatine. The problem is that several of the studies have shown different results, so as yet there is no clear answer as to whether it is better to take creatine before or after exercise. There are a couple of studies that indicate that taking creatine after exercise is better than taking it before, but other studies show no difference in results between taking creatine before exercise and taking creatine after exercise.

The one thing that seems clear from the research, however, is that it matters how close to your exercise you take creatine supplements. There is evidence that indicates that taking creatine either just before or just after exercise offers noticeable benefits over taking it early in the morning or late in the evening, further away from the times at which you exercise.

So, overall, it’s not entirely clear when is the best time to take creatine, but it seems to be worth taking it as close as possible to when you exercise. Splitting your dose in half and taking half just before you exercise and the other half just after you’ve finished exercising seems to be a good option that offers significant benefits, but there’s nothing wrong with either taking all of it just before or all of it just after exercise if you don’t want to go to the trouble of splitting your dose into two sessions.

When to take creatine on rest days

The timing of your creatine pills or powder is much less important when you’re taking it on days when you’re not planning on exercise. All you’re aiming to do when taking creating on rest days is to boost the creatine levels in your muscles and keep it at a higher level constantly even when you’re not exercising. It doesn’t matter when during the day you take it, as you aren’t doing any exercise that might use the creatine, only that you continue to take the creatine supplements on a regular basis.


Whether you’re a relatively casual exerciser or a serious body builder, it pays to understand how creatine works, what creatine does, and when to take creatine before you start to take creatine supplements on a regular basis. Hopefully, the guide above has given you enough information to understand everything you need to know about when to take creatine and the scientific backing of the various arguments around the advantages and disadvantages of creatine.

As long as you take creatine somewhere near to when you work out each day, you should be able to get some sort of benefits from this supplement. The full extent of its effects will vary from person to person, and will depend on your particular workout routine, but most users should be able to achieve some small boost to their exercise performance.
