Ask The Supplement Guru: When Should I Take Creatine?
Q It seems like everyone I know is using creatine these days, but not everybody takes it at the same time. Recently, I heard post-workout is better. What's the lowdown?
I will start this Ask the Supplement Guru by noting that I have recommended taking creatine both before and after workouts for more than a decade. It simply works the best in the gym, and research also backs up this practice. However, debate is still raging among other experts on whether it is best to take creatine pre- or post-workout.
Well, for people who only want to take creatine once a day, a recent study by a colleague and friend of mine, Dr. Jose Antonio, may have the answer for you … or not.
Researchers gave recreational male bodybuilders—basically guys like you and me—either 5 grams of creatine monohydrate immediately before they worked out for four weeks, or 5 g of creatine monohydrate immediately after they worked out. On non-training days the subjects were allowed to take the creatine whenever they desired.
Antonio and co-author Victoria Ciccone reported in a 2013 issue of The Journal of The International Society of Nutrition that there wasn't any significant difference between the two groups for lean mass gains, body fat, or muscle strength. However, when they ran some much weaker statistical correlations, there was evidence that taking creatine post-workout was more effective on lean muscle gains and muscle strength.
Predictably, a bunch of magazines, websites, and pseudo-scientist bodybuilding "experts" took this as conclusive proof that taking creatine post-workout is far superior than taking it pre-workout. My message to them is: not so fast.
The Case for Pre and Post
I want to be clear that I am not bashing Dr. Jose Antonio or his research. I consider him a very smart person, and he correctly stated in the paper that there were no significant differences between taking creatine pre-workout or post-workout. It was only when they used what's called "magnitude-based inference" that there was any evidence that post-workout might be better than pre-workout.
Unfortunately, there has yet to be a study published that compares taking creatine both pre- and post-workout to taking it just pre-workout or just post-workout. But the real-world results I have seen in thousands of people switching to taking creatine at both ends of working out are significant, and there's some research to support making the switch.
A 2006 study done by Australian researchers reported that weight-trained subjects taking a protein, carbohydrate, and creatine shake immediately pre- and post-workout for 10 weeks experienced an 80 percent greater increase in lean muscle mass and about a 30 percent greater increase in muscle strength than subjects taking the same supplements in the morning and at night. The pre-and-post group also lost body fat, whereas the morning-and-night group didn't. The pre-and-post group also showed significantly higher muscle glycogen levels, which is critical for performance and muscle growth.
Many people would argue that because the subjects were taking a protein shake and fast-digesting carbs (glucose/dextrose), the results don't truly reveal how effective the creatine was. While it's true that it is hard to tweeze out exactly what benefits were due to creatine versus the protein and carbs, I would reply that this is precisely the way you want to take creatine. Taking creatine alone is not half as effective as when you take it with protein and carbs.
In fact, the recent ISSN study comparing pre-workout to post-workout creatine supplementation had subjects take just creatine and nothing else. I argue that since that is an ineffective way to take creatine, it compromises any findings in the study. But since there weren't any conclusive findings, it doesn't really matter.
Stay Ahead of the Curve
The new study has been making the rounds in online forums and gym-chatter, and I've already seen far too many people stating conclusively that taking creatine post-workout is far superior to taking it pre-workout.
When you hear them, you can have a laugh knowing that a) they didn't actually read the study in its entirety, b) they don't know what they're talking about, and c) you're way ahead of them on this one.
My advice to you is to do what works best when it comes to supplementing with creatine: Take it both pre-workout and post-workout, in your pre- and post-workout shakes. Creatine is cheap and effective, and this is an easy way to get more out of your training.
If you use creatine monohydrate or most other forms of creatine, then go with 5 grams both pre- and post-workout.

great article, everyone i knows takes creatine post workout but alot of pre workout drinks already have 3-5 grams of creatine in it, so alot of people are not realizing your really taking it both pre and post
It's possible that it's true, but you shouldn't follow everything he says just because it says "Dr" before his name.
The man is just SLIGHTLY larger than your average adult male.
You know why, ppl don't realize that because, we are BLIND, we don't like read the nutrition facts of the stuff, we use just look that bottle its shinny I got that one. That why we waste lot of money.
The size of the guy means absolutely nothing in regards to how much he KNOWS. Are you telling me the world's strongest man doesn't listen to anyone but himself all the time because he's bigger and stronger than everyone else? No. Genetics are a huge factor in potential size and strength for anyone. Why is it that as soon as it comes to weight training, people pretend absolutely everything you have is 100% earned? People always try to say "blaming genetics is an excuse" but let's be real. In AND out of the gym, people are entirely different sizes and strengths. You can't evaluate ANYONE's knowledge based on what they look like. That should literally almost never be a consideration in taking someone's advice.
I agree with G00185175 who says the guy even wants to be a hulking monster. Just cause I know how to get fat doesn't mean I should be a huge lard ***. Not every one wants to be the hulk some people just want to be thor. Then again never take advice from and obese personal trainer there's limits.
I just have one question as I am not yet using a creatine supplement but plan to do so soon. If i take the pre-Jym workout supplement which has the Creatine HCL, do I have to take another Creatine HCL supplement post-workout, or can i just use the 5g monohydrate? In other words, must I match the type of creatine taken pre and post-workout for best results?
I wouldn't think so. I'm no expert by any means, but from experience training, and going through the trial and error of trying and using many different supplements and brands, I would say that "matching" the creatine wouldn't matter. I do know that different creatines are "shuttled" and absorbed by the body at different rates, which is why alot of products now contain a creatine blend of mono, HCL, Kre-alklyn, chelate, etc...
I know in Dr. Stoppani's programs call for creatine before and after. I use his pre and I still take 1-2 servings of creatine after my workout.
you can use Creatine mono or Hcl at post doesn't matter you just use what fit to your pocket Hcl is a bit more expensive
creatine is creatine, there is no significant research proving one is better than the other
According to the Pre Jym ad, Dr. Stoppani explains why he says you don't need as much Creatine HCL:
"Adding the hydrochloride group lowers the pH of creatine, making it more acidic. This drastically increases its solubility in fluids, which increases absorption of the creatine and prevents any stomach issues."
Research suggests that when subjects consume the same amount of creatine HCL and creatine monohydrate, the creatine HCL is absorbed by the intestines about 60% better than creatine monohydrate.* This means you can take a much smaller dose of creatine HCL to get similar results."
Stopppani is a Guru indeed , dude knows his **** inside and out ..
I always believed that creatine was best taken when your body is in a state of "shock" rather than a state of Recovery..
Awesome article , will definitely be using this knowledge for my future creatine intake :)
Thanks for the informative article, Jim! Do you (or anyone else, for that matter) know whether caffeine significantly diminishes the effects of creatine? I've read articles stating that as long as you space out your creatine and coffee consumption, you'll be fine. I've read other studies, however, which state that any consistent significant caffeine intake during a creatine cycle will provide limited benefit from the creatine. I'd love to know if any of you know more/have anecdotal evidence one way or another.
Keep up the great articles, Jim.
Most of the comments are nothing more than examples of imagining it working. Creatine isn't going to mske you're pump better or magically give your muscles more atp within 30 minutes before you workout. Take it anytime neara workout and after a week your muscles will be saturated.
I have to agree here. My pre-workout has some creatine in it, but it's not much. The majority of it is 5g of monohydrate post workout. As long as you keep replenishing what you burn during a workout at some point, I personally don't think there will be much of a difference. I take it with 30g protein and 40g carbs in my post workout shake for maximum absorption.
