What Is Creatine? How to Start Supplementing with Creatine


Most supplements in the fitness world are a complete waste of money.

Some supplements aren’t even absorbed well, making for some expensive urine! [ 1 ]~ ATAGEND

Others, like “weight loss pills, ” can actually be outright dangerous.[ 2 ]~ ATAGEND

However, there are a few supplements which could be an exception to this rule.

And one of those supplements is creatine.

Creatine is one of the more popular and tested fitness supplements on the market.

Technically, it’s an amino acid derivative, but you don’t truly need to know that.

That is, unless you are a chemist.

We get loads of questions here at Nerd Fitness on using creatine correctly, so today I’ll jump right in and give you the low down.

We’ll discuss everything you need to know about this supplement 😛 TAGEND

What exactly is creatine? If you were to take creatine, how much should you use? What time of day is best for taking creatine? What are some of the best creatine supplements on the market?

Let’s go!


Creatine is a naturally occurring substance found in muscle tissue.

Right now you have creatine, specifically creatine phosphate, in your body. All vertebrate animals do.

Yes, even corgis.

Think of creatine as an energy reserve your body taps into when it needs a boost. Or like, an extra energy tank in Metroid or Mega Man.

Our bodies naturally create creatine in our liver, pancreas, and kidneys.

We also procure it from certain foods, because all vertebrate animals contain creatine in their muscles.

So if you feed meat, you are getting extra creatine in your diet. Red meat in particular( beef, lamb bison ), has the highest levels of dietary creatine.

( Don’t eat meat? Cool. Read our plant-based guide .~ ATAGEND)

Outside of diet, people often supplement with creatine. It’s one of the most popular supplements taken, and in fact, is THE most popular supplement taken amongst college athletes.[ 3 ]~ ATAGEND

The reason people supplement with creatine: the more creatine you eat- whether through nutrition or supplementation- the more will be found in your muscles.

Why should you care? What does creatine do, precisely?


Science time! To discuss supplementing creatine with any justice, we need to talk about ATP.

All cells rely on adenosine triphosphate( ATP) for energy. It’s our body’s energy currency.

Sort of like “Mana” in World of Warcraft or Magic: The Gathering, ATP is a fuel tank for doing awesome things like running, doing pull-ups, or summoning lighting.

But much like “Mana, ” ATP can be replenished merely so quickly by your body. With intense enough exert, you’ll use more ATP than your body can render. Which means you’ll run out.

It’s why people can only sprint at 100% maximum effort for a short sum of day. You just plain run out of juice, or ATP.

And depending on how you are exercising, your body will replenish its ATP through one of three routes:

Less than 10 seconds, for workouts like short sprints or heavy lifting, ATP is replenished with creatine phosphate stored in muscle tissue. 30 seconds to 2 minutes, for activities like swimming a few laps, ATP is replenished with glycogen found in your muscles. Greater than 2 minutes, ATP is replenished with oxygen and glucose. You can think of endurance activities for this stage.

I get it, there’s a LOT more to it than that( The three systems often blend into each other, so it’s not so clear cut ). [ 4 ]~ ATAGEND

Why I bring all of this up: your body can quickly convert creatine to ATP( in seconds ).

This entails the more creatine you have stored in your muscles, the longer you can utilize the phosphagen system- short and intense energy- to create ATP.

It’s math: the more creatine you consume, the more will be found in your muscles. The more creatine you have in your muscles, the longer you should be able to sprint at max endeavour( or lift heavy, etc .).

Granted, there’s a phase where your muscles become saturated with creatine and your body can’t hold anymore.

We’ll talk about dosage and absorption rates shortly. But first…


There is good evidence to suggest that creatine supplementation does, in fact, allow for longer periods of intense exercising by helping to produce more ATP. [ 5 ]~ ATAGEND

One such study found that supplementing with creatine for 28 days allowed users to increase their bike sprint by 15% and bench press performance by 6 %. [ 6 ]~ ATAGEND

This is generally why it is supplement with creatine. If you can create more energy for more intense workouts, you can workout harder.

Instead of stopping at 10 reps because of exhaustion, perhaps you can squeeze out that 11 th rep if you are storing more creatine. Or instead of slowing down your sprint at 10 seconds, you keep going until 12.

If you’re looking to improve physically, being able to achieve one more rep or just a few more seconds of a sprint can be critical.

Creatine has a boatload of other benefits too 😛 TAGEND

Cell signaling. Creatine has been shown to increase satellite cell signaling, which helps your body communicate its “needs” better. I personally picture a little cell crying out “help me, I’m broken” when thinking about cell signaling. However, improvements in cell communication can have an impact on muscle mend and growth.[ 7 ]~ ATAGEND

Cellular hydration. Creatine helps your muscles retain water, which helps them run more efficiently. [8 ]~ ATAGEND Hydrated muscles perform better than dehydrated muscles, so creatine as a performance enhancer seems appropriate.

Muscle growth. Creatine supplementation has been shown to increase the hormone IGF-1, which is needed for muscle growth.[ 9 ]~ ATAGEND In fact, the International Society and Sports Nutrition countries “Creatine monohydrate is the most effective ergogenic nutritional supplement currently available to athletes in terms of increasing high-intensity workout capacity and lean body mass during training.”[ 10 ]~ ATAGEND

Don’t get thrown off by the “creatine monohydrate.” We’ll talk about types of creatine shortly. Just is recognized that creatine has been shown to aid in muscle growth.

Brain health. While not technically a muscle, your brain stores creatine. Can more stored creatine help with brain health?

There is research and evidence that indicates some conditions like Alzheimer’s, Parkinson’s, and epilepsy can all be helped by supplementing with creatine.[ 11 ]~ ATAGEND A creatine supplement might also help with memory and cognition in the elderly.[ 12 ]~ ATAGEND

Also, I have to highlight this study connecting creatine supplementation with running memory and intelligence.[ 13 ]~ ATAGEND This builds sense because your brain also uses ATP, which remember, creatine helps produce.[ 14 ]~ ATAGEND

All of these studies are going to lead to a natural question…


The use of creatine has been “extensively studied, ” which builds my job of recommending it easy.[ 15 ]~ ATAGEND

The International Society of Sports Nutrition analyzed over 500 studies on creatine utilization and concluded: “There is no scientific evidence that the short- or long-term employ of creatine monohydrate has any detrimental effects on otherwise healthy individuals.”

However, we should acknowledge there is anecdotal evidence that taking creatine can cause kidney injury, dehydration, diarrhea, and an upset stomach.[ 16 ]~ ATAGEND

Kidney damage would be the most serious of these, let’s talk about that specifically for a moment.

Again , no study has been able to verify the claim of organ injury, and kidney function with creatine supplementation has been looking back on specifically.[ 17 ]~ ATAGEND

However, if you have a history of kidney problems, it might be a good idea to talk to a doctor before you start supplementing with creatine. Better safe than sorry.

The other concern would be dehydration and diarrhea, which actually might have an easy cause and solution.

I mentioned earlier that taking creatine can help with muscle hydration. Because your muscles are holding onto more water, this leaves less water for other places. So if you start taking creatine, you should also increase your water uptake!

Shoot for 16 -1 8 ounces of water( a half liter) for every 5 grams of creatine you take. We’ll devote an entire section to dosage in only a moment.

It should also be noted, that being dehydrated puts extra stress on your kidneys. It can also cause diarrhea.

Drink water.


The reason creatine is so popular is because of its impact on athletic performance.

For you to receive most the benefits of supplement creatine, you’ll need to work out. The creatine won’t lift that barbell for you.

The interesting thing about creatine: nearly any type of physical performance has been linked to improvement when combined with creatine supplementation 😛 TAGEND

Strength training. If you’re looking to grow strong, you need to lift heavy. Taking creatine has been shown to increase muscle strength.[ 18 ]~ ATAGEND In other terms, taking creatine can assist you lift somewhat heavier or slightly more. If you do this consistently, you could start to achieve gains faster than you would without creatine supplementation.

This is the number one reason people take creatine.

Endurance. Despite creatine’s popularity for strength training, it can also be used as a tool for endurance athletes. That’s because creatine has been shown to increase glycogen stores.[ 19 ]~ ATAGEND If you remember our instance from earlier on different metabolic ways to replenish ATP, you’ll recall that glycogen is a medium to long term energy source.

Meaning the more glycogen you have, the longer you can run. If you’re looking into improving an endurance sport, creatine might be worth checking out.

Recovery. Creatine has been shown to help reduce rednes and muscle soreness.[ 20 ]~ ATAGEND Shorter recovery periods, means you can get back to educate sooner. More gym day can equal a stronger you.

No one likes being overtly sore. Creatine may help a little here.

When you start to learn more about creatine, it makes sense why so many athletes take this supplement.

However, I do need to mention that a majority of the benefits of creatine supplementation kick in with the conjunction of a regular exercise practise.

Supplements must be combined with a good solid workout! You don’t get big muscles or faster velocities from only protein and creatine.

They need to be combined with a proper training program!

If you’re not quite sure how to get going, I’ve got a few resources for you.

The first is our Beginner Bodyweight Workout.

It’s a circuit- where you rapidly go from one exert to the next– that you can start doing tonight in your living room or basement or spaceship. It’s one of our most popular routines here at Nerd Fitness, and it’s something you can do from your own home. No gym required.

If you want someone to help guide you- and hold you accountable- we can help with that too!

So far this article has more or less come out as an advertisement for creatine supplementation.

While there are a lot of great benefits of creatine, and not much in the way of studies presenting harm, we need to talk about one potential downside.


Since creatine helps you retain water, you might feel a little bloated after taking it. Granted, hydrated cells perform better. But it can still be uncomfortable and cosmetically unappealing to hold onto a bunch of water.

The dosage and timing of taking creatine might be a factor, which we’ll talk about soon.

However, if bloating continues to the point that it’s interfering with their own lives, stop supplementing with creatine.

Speaking of creatine challenges, there’s also the fear that taking too much creatine could upset your stomach.[ 21 ]~ ATAGEND

We’ll get to proper dosage of creatine in simply a moment, which might solve this.

It should be noted, that certain types of creatine are sold as “anti-bloating” and “easy on the stomach.”

Let’s talk about kinds and brands of creatine right now, by looking into these asserts.


Creatine actually exists in multiple sorts. We’ll go over each one briefly, plus give our recommendation on which form to take.

We’ll then leave you with a brand or two to try out.

First, some different types of creatine 😛 TAGEND

Creatine Monohydrate is the most common, and thus the most studied kind of creatine.

It’s basically a creatine molecule and a water molecule combined.

This would be the form of creatine we recommend. When we discuss the benefits and safety of creatine, we mean creatine monohydrate, because it’s the sort that aims up being used in research.[ 22 ]~ ATAGEND

If there is a downside to creatine monohydrate, it would be that your body might have trouble absorbing all of it.[ 23 ]~ ATAGEND Which means you can pee a lot of it out. When people sell other types of creatine, they’ll generally claim their version has a better absorption rate.

Creatine Ethyl Ester is thought to be absorbed into the body easier than creatine monohydrate. There may be some evidence this is true.[ 24 ]~ ATAGEND

However, when it is necessary to body composition, creatine monohydrate still looks to be superior.[ 25 ]~ ATAGEND

Creatine Hydrochloride is another form of creatine that is touted as being absorbed easier than creatine monohydrate. You’ll also find claims that it won’t make you bloated.

Early evidence may back some of the claims of better absorption rates, but I would hold off on this form of creatine until more studies are done on its safety.[ 26 ]~ ATAGEND

Buffered creatine attempts to solve the stomach issues that are anecdotally reported as a side effect of creatine consumption. This form of creatine is mixed with an alkaline powder, with attempts to make it easier to digest. So far studies on the results of these benefits are mixed.[ 27 ]~ ATAGEND

Again, for now, I’d avoid buffered creatine until the research concludes its safety.

Hopefully, I persuaded you to stick with creatine monohydrate. Again, it’s the most tested version of creatine there is, which constructs it the most recommended.[ 28 ]~ ATAGEND

Want some recommendations on brands?

The brand of creatine monohydrate I personally take: Bulk Supplements.

dotFIT is another good brand for you to check out. MyProtein also carries a good option. Both of those are creatine monohydrate options.

If you are going to take creatine, take creatine monohydrate. Which leads to the next question…


The question “How much creatine should I take? ” will lead us to the topic of creatine loading.

The theory on creatine loading runs like this: at first, you’ll want to take more creatine so your muscles start storing it in greater sums. Then you are able to taper off, as your muscles will already be saturated to their max with creatine phosphate.

Studies have shown this is the most effective way to increase creatine levels in muscle.[ 29 ]~ ATAGEND

Note, your results may differ, though the strategy below is well researched. Do what works best for you! I’m no physician , nor do I play one on TV.

For 5 days, ingest 20 grams of creatine per day to’ load’ your muscles. After this period, then you can go to 3 to 5 grams of creatine per day.

If you’re concerned about taking 20 grams of creatine a day( more is not necessary or beneficial ), the other strategy would be to be taking 3 to 5 grams of creatine a day. In three to four weeks your creatine stores will be full.[ 30 ]~ ATAGEND

If you have stomach issues such as 20 grams a day, forget about loading. Stick to 3 to 5 grams a day and you’ll be fine.

This is the strategy I employ: 5 grams of creatine on training days mixed in a small amount of water, consumed like a shot, immediately following my workout.

Which leads us to…


Studies demonstrating the best time of day to take creatine are mixed.

When it comes to “Should I take creatine before or after my exercise? ” this study showed it didn’t actually matter.[ 31 ]~ ATAGEND

It might be up to your personal predilection on whether to take creatine before or after your educate.

However, there is evidence you should take creatine somewhere close to when you exert.

One study split topics into two groups. The first supplemented with creatine immediately before and immediately after their workout. The other took creatine first thing in the morning and again at night.

The study discovered the first group gaining the most muscle and strength.[ 32 ]~ ATAGEND

I would recommend taking creatine either before or after your training practice. Maybe split your intake and do a little bit of both. Take a mix with you to the gym, start drinking it before working out and finish it right after.

On rest days, when you take creatine matters less. The phase of taking creatine on a rest day is to keep the creatine phosphate content of your muscles raised for when you do workout next.

Take it whenever it is convenient on rest day. But take it close to when you workout on a educate day.


You don’t need to supplement with creatine.

If you’re feeing a varied diet that includes a little bit of meat, you’ll be devouring and building plenty of creatine.

Our stance at Nerd Fitness: if you have a healthy diet, you don’t need to worry about any kind of supplementation. Eating nutrient dense foods like veggies, fruit, and meat will provide you with all you need to thrive.

However, if you are strength training and looking to maximize your gains, a creatine supplement might be worth is currently considering.

There’s decent proof in support of it allowing people to increase their athletic performance.[ 33 ]~ ATAGEND

And all of the downsides of creatine don’t appear to be supported by the data.[ 34 ]~ ATAGEND Although to be fair, more long term studies will be welcome on the safety of creatine supplementation.[ 35 ]~ ATAGEND

However, simply to be safe, if you have any history of kidney difficulty, make sure you talk to a doctor first before you start supplementing with creatine.

Okay, I think that about wraps up the article on creatine.

Now I want to hear from you 😛 TAGEND

Do you have experience taking creatine? What outcomes did you consider?

Does it sound like I’m being sponsored by the supplement industry? Or am I not praising creatine enough?

What other supplements would you like me to look into?


PS: As a reminder, if you’re looking to take creatine for a boost in athletic performance, you need to actually train. If you don’t know where to start, we can help! We offer a 1-on-1 Online Coaching program to help busy nerds just like you level up their lives.
