The guys at the gym rave about the benefits of creatine. Your mom says taking it will ruin your liver, or something. But do you even know what creatine is, how it works, and how to use it to maximize its efficacy?
There are a lot of myths and “bro science” out there about this supplement that’s used by athletes in a wide range of sports and fitness disciplines. So today we’ll cut through the confusion, answering the above questions and taking a look at all the what’s, how’s, and why’s of this popular performance-enhancer.
What is Creatine?
Contrary to what Baby Boomer mothers often think, creatine is not a dangerous, completely synthetic drug that’s only found outside of nature. Nor is it a steroid. It’s a substance that’s found in the bodies of animals, and your own body as well.
Creatine is a nitrogenous organic acid found primarily in the skeletal muscle that helps muscles get the energy they need to contract (more on that in a bit). Your body makes about a 1-2 grams of creatine a day from amino acids, and overall, your body is composed of about 1% creatine. You also ingest creatine whenever you eat the meat of other animals, like beef, chicken, or pork. In fact, the higher the percentage of creatine in a piece of meat, the higher quality it is.
Of course, the creatine you buy as a supplement is made synthetically in a lab, but its molecular profile matches that which is found in the body, and as we’ll see, is quite safe to take.
What Does Creatine Do?
To understand what creatine does, it’s necessary to know a bit about the cellular energy cycle. All cells in your body are powered by adenosine triphosphate, or ATP. When you walk, you’re using ATP. Deadlifting? Powered by ATP. Thinking about Teddy Roosevelt riding a moose? Brought to you in part by ATP.
ATP can be produced in three ways:
- Through oxygen-dependent metabolism that utilizes fatty acids (oxidization). This is how most of the ATP you use throughout the day is created. When you breathe, oxidation is turning fatty acids into ATP.
- Through non-oxygen dependent glucose metabolism (glycolysis). If you’re doing an intense exercise like sprinting or lifting weights, your body switches from oxidizing fatty cells to produce ATP, to burning glycogen/carbs to replenish ATP stores. Glycolysis produces large amounts of ATP, but the buildup of hydrogen ions and lactate make its production unsustainable over long periods of time.
- Through the recycling of previously stored ATP. This is the ATP production mechanism that interests us for this article, because what does this recycling? Creatine! When ATP is transferring energy to cells, it breaks off one of its phosphates and becomes adenosine diphosphate (ADP). Creatine then comes along and says, “Hey, ADP, you can have my phosphate,” turning it back into ATP to once more be utilized as energy.
The more creatine you have in your system, the more ADP that can be recycled back into ATP. The more ATP you have, the more weight you can hoist or the faster you can sprint. Creatine, thus, can help make you bigger, stronger, and faster.
What Are the Benefits of Creatine?
Not all nutritional supplements are created equal. In fact, erectile dysfunction drugs online viagra soft.
But one supplement has been studied heavily for the past 35 years and consistently been shown to be safe and effective: creatine.
Creatine is in fact one of the most well-researched nutritional supplements on the market. Below are some of the benefits studies have proven come from this supplement:
Creatine can help make you stronger. Several studies have shown that creatine supplementation results in strength gains. express viagra 100mg, researchers found that individuals who use it show an 8% increase in strength compared to those who don’t.
Creatine can help your muscles grow bigger. Creatine makes your muscles look bigger, while actually making them bigger as well. First, creatine causes your muscle cells to store more water which causes your muscles to appear fuller and larger. You may notice the size increase a few days or weeks after starting creatine supplementation. (Keep in mind that if dropping sheer poundage is what you’re after, like in preparation for a wrestling weigh-in, this water retention may not be something you desire.) The other way creatine can help your muscles grow is that it can help you to lift heavier weight at more volume. Over time, your muscles will get bigger from this increased intensity.
Creatine can help you sprint faster. Research has found that creatine supplementation can increase sprinting speeds. So if you want to get faster, supplementing with creatine can help.
Creatine can speed up recovery. Intense exercise causes your muscle fibers to tear and creates inflammation. Some research suggests that supplementing with creatine can reduce the cell damage and inflammation that occurs during intense training, thus speeding up recovery. The faster you can recover, the faster you can achieve those gains goals.
Creatine may help strengthen your brain. While the bulk of your body’s creatine resides in its musculature, smaller amounts are also found in your testes and brain. It takes a lot of energy to power your brain and, just like in your muscles, that energy transfer is carried out through ATP. Creatine has been found to play a major role in ATP levels in the brain. One study found that higher creatine concentrations in the brain resulted in improved mental performance and that this concentration can be increased substantially by supplementation.
Creatine is inexpensive. Not only is creatine more effective than almost all other supplements, it’s also a whole lot cheaper, on the order of $13 for 114 servings, or 12-budget-friendly-cents a serving.
Creatine is safe. After 35 years of testing on infants, athletes, and adults. Creatine has been found to be completely safe, even after years of use. It won’t damage your kidneys or liver. It doesn’t cause dehydration. The only issue you might have is nausea or diarrhea, but that only happens if you take too much.
How to Take Creatine
Safe, greatly beneficial, and inexpensive…if you regularly engage in intense athletic training, there’s really no reason not to supplement with creatine.
Here are answers to some of the common questions guys have about how to start using this supplement:
What kind of creatine should I take?
There are different types of creatine being marketed out there. Stick with creatine monohydrate. It’s the cheapest, and it’s the kind that’s actually been proven to work.
How much creatine should I take per day?
It’d be easy to think, “If creatine helps me recycle ATP, then the more creatine I have in my body, the better. Give me all the creatine!” But that would be wrong. Your muscles can only process and store so much of it.
So how much is enough?
There are all sorts of answers out there to that question. The standard daily dosage recommended by companies selling creatine is 5 grams daily.
Other sources recommend customizing creatine dosage based on bodyweight. The most common recommended dosage is .3 g of creatine per 1 kg of body. So if you weigh 200 pounds, your daily dosage would be 2.72 g of creatine a day (90.7 kg x .3 g).
But let’s be honest, measuring out 2.72 g every single time you take creatine would be a pain in the rear. And it may not be enough for you — it’s just an estimate.
Personally, I just use the 5 g scoop that comes with my creatine powder. Am I possibly pissing away excess creatine? Perhaps. But I know I’m getting an adequate dose, and there’s no ill-effects of taking that much creatine daily.
Can I get enough creatine from eating meat without supplementing?
It’s possible, but to get the recommended dose of 5 grams of creatine a day, you’d need to eat about 2 pounds of beef or 3 pounds of chicken. That’s a crap ton of meat, and also expensive — much more expensive than creatine. 5 grams of creatine from a supplement will run you 12 cents, while 5 grams of creatine from chicken breasts will cost you almost $10.
Should I start taking creatine by doing a “loading phase”?
Your muscles can store about 3 grams of creatine per kilogram of lean muscle mass. So if you’re a 200-lb dude, your body can store about 272 g of creatine in its muscles. That’s potential though — if you’ve ingested enough creatine to saturate them to that level.
With that in mind, companies that sell creatine powder recommend that when you first start taking it, you begin with a “loading phase” that involves taking a high dosage of 20 grams per day (taken 4X a day in 5 g doses) for a week or two.
Once your muscles have become “super saturated” with creatine, you move into a “maintenance phase” where you take the usual 5 g a day.
While it’s true that a loading phase will saturate your muscles with creatine quickly, it might not be necessary. Research has shown that taking 3-5 g a day from the get-go will eventually result in creatine saturation. It just takes longer for the saturation to occur.
So whether you load or not is up to you. Mega-dosing during a loading phase won’t cause any ill-effects except for maybe some nausea or diarrhea.
Do I need to take creatine forever?
You don’t need to take creatine forever. You can stop supplementing anytime you want. But your muscles’ creatine levels will start to deplete about two weeks after you stop taking it. In 4-6 weeks, the extra creatine will wash out of your muscles altogether, and your body will be back at producing its baseline level of 1-2 grams a day. According to one study, even when continuing to supplement with 2 g a day of creatine after a loading phase, instead of the recommended 5, the creatine in participants’ muscles still fell to baseline levels within 2 weeks due to their strenuous exercise routine.
Some fitness experts do recommend that you cycle off creatine for a month every 12 weeks or so. Why? There’s lots of bro-science reasons thrown out as rationales, like ensuring that your body can still naturally produce creatine or to avoid other possible negative side-effects.
Actual science has shown that there’s no reason to cycle off creatine. While you take it, your body’s own production of creatine will slow some, but it will continue to produce it, and your natural levels will return to normal if/when you do stop taking it. And as discussed above, there have been no negative side-effects found with the daily, prolonged use.
So, no, you don’t have to take creatine forever. But if you want to get the most from its benefits, supplement with it daily. It won’t hurt and it’s cheap.
Should I use a powder or capsules?
It doesn’t really matter in terms of efficacy. I would recommend powder because it’s cheaper per gram.
Does it matter when I take it?
Nutrition timing is something that confuses a lot of men. You’ve likely read or heard about magic “windows” in which you need to consume certain nutrients to get the maximum benefit from them. As we discussed in our article about pre- and post-workout meals, however, you shouldn’t over-think this stuff. Your overall diet plays more of an important role in your physique and strength than the exact timing of when you eat.
The same goes for creatine. One study in 2013 showed that supplementing with creatine after a workout resulted in better strength gains. The insulin spike that occurs after a workout may do a better job of transporting creatine into muscle cells. But the difference between individuals who supplemented before their workout or after wasn’t that much. The researchers concluded they needed to do more research on this question to come to a definitive answer.
So just take your creatine supplement when it’s convenient for you. Personally, I take mine with my mid-morning protein shake.
Do I need to take creatine with carbs?
Research is mixed on this question. One study found that ingesting creatine with fast-acting carbs improved athletic performance compared to individuals who just consumed creatine, while another found no difference.
Again, my philosophy with nutrition supplementation is to keep it simple. If you have a post-workout shake that has carbs, throw in a scoop of creatine. There’s a chance you’ll get an added benefit from consuming creatine with your carbs. If you usually skip breakfast, take it on an empty stomach. Or save it to take with your dinner. Don’t stress — do whatever works for you.
Is it okay to take creatine with caffeine?
One study in 1996 found that consuming caffeine with creatine counteracts the benefits of the latter, but the study wasn’t well-designed, and other studies have found no deleterious effect. So feel free to take your creatine with your coffee or caffeinated pre-workout shake.
Can you take creatine with juice?
You’ll see blog posts or forum comments out there claiming if you take creatine with juice, the acid in the juice will cause the creatine to break down and lose its effect. However, several studies done on creatine had the subjects consume creatine with juice and they still reported beneficial effects.
If you think about it, if acidity counteracted creatine’s benefits, then creatine would be doomed the moment it entered the acidic swamp that is your stomach. But that doesn’t happen. So feel free to take it with juice.
Can young people take creatine?
I remember back when I started supplementing with creatine when I played high school football, my mom was a bit concerned. But research has found no negative effects from creatine use in young adults or even children. In fact, doctors will often prescribe creatine to children with certain neuromuscular disorders. If you’re a young man or are a parent of a young man, you shouldn’t worry about creatine supplementation. Most doctors simply recommend that you wait until after puberty starts and make sure you stick with the recommended dosage.
Can creatine make me big and strong even if I don’t lift and exercise?
Is that you, Cartman? Like all supplements, creatine will have no effect if you don’t push yourself in the gym and maintain a healthy diet. Creatine can help you push a little farther, but it won’t turn you into a beefcake if you don’t do the work.
Do the work!
