creatine-side-effects.jpgToday I’m going discuss creatine side effects. For such a widely used supplement, most people know very little about creatine and how it works. This has lead to some wild rumors flying around about creatine. Some of these rumors are funny, others are simple ridiculous!

As a result of these rumors some people are very vary, or even scared to take creatine. This is a typical example of how misinformation spreads out of control. It’s a pity, because creatine is such a good supplement for explosive power, strength increasing and muscle building.

I have researched the positive and negative side effects of creatine thoroughly, and have written the lists below.

Positive Creatine Side Effects:

  1. You’ll feel stronger, be able to train for longer, and have a lot more energy available for workouts. Creatine helps you to push out those last few reps in the gym, which leads to more muscle growth.
  2. Your muscles will get bigger. Creatine is stored in the muscles, and also increases the amount of water stored in the muscles. This makes the muscle look bigger.
  3. Creatine decreases the amount of lactic acid build up in muscles. Lactic acid causes the burning pain you feel when you’re working out. Less pain also means that you can punch out more reps!
  4. Weight gain – most users report an almost instant weight gain when starting on creatine.
  5. More explosive power. This is a huge advantage to those who are involved in strength sports that require instant power. This can be anything from a 100m sprinter, to a powerlifter, or shot putter.

For more positive information about creatine see the creatine benefits post I made.

Possible Negative Creatine Side Effects:

  1. Bloating is a side effect that some users have reported when taking creatine monohydrate. While this is rare, it is a side effect. Bloating has not been reported with other forms of creatine.
  2. It’s common knowledge that creatine monohydrate can cause dehydration. Obviously, the simple solution to this is to drink more water. Athletes should be drinking more water anyway, so reports of dehydration are still very few. Again, these side effects have been reported only with creatine monohydrate.
  3. Some extremely rare cases have been reported where creatine has caused kidney stones. Little is known about exactly how creatine is linked to kidney stones. These cases are very rare.

Little is known about the long term effects of supplementing with creatine. It still is a relatively new supplements, so scientists have not been able to conduct any true long term studies. Users of creatine that are worried about long term side effects can cycle creatine. This means you take creatine for 6-8 weeks, then stop for 2-4 weeks. This means the body is less dependent on supplements for creatine.

The bottom line.

Creatine works. Lifters know it, scientists know it and trainers know it. There are some possible creatine side effects, but these cases are few and far between.

I have always recommended creatine to most athletes I’ve worked with. It’s what I consider an essential supplement for strength trainers. If you have any questions about the creatine side effects feel free to post them in the comments below and I’ll answer them as soon as possible.

I took an life insurance policy blood test and they are telling me I have elevated levels that can possibly be renal failiure of the kidneys. I was cycling creatine at the time and I told the company that. I feel fine, I drink water while cycling. I am 39 years old and have been taking creatine for several years by cycling it. I have tested high in my creatine levels before and when I told the doctor about the supplement he didn’t seem concerned. Will using creatine show the type of blood results the insurance company is concerned about? I am due to come off the cycle and will probably follow up with my physciian just to be sure.

Hi Chuck, It’s not unusual to test with high levels when you’re on creatine, that’s just good a good sign that it’s working :) You should not have any kidney trouble with creatine, as long as you keep your water intake high (around 3lt a day).

Definitely follow up with your doctor on this though.

Hi Tomas, you’re not too young start taking creatine. Creatine can help you with energy in short bursts, like sprinting and jumping so it could help you out with soccer.

seanaarchr - 15 Dec 08 at 10:04:45

hi i just wanted to say that my husband has been taking creatine for quite a while now, and it turns him into a psycho!! so beware if you want to become a very angry person then take this stuff oother wise stay away! and i know this for a fact cause whens he is not on it he is great! to bad he is going to lose his family over a supplement!

CSG Admin: Peter - 02 Mar 09 at 20:03:17

Vanessa – it’s comments like that that spread the COMPLETE MYTHS about creatine. Creatine is not hormonal, thus it has absolutely nothing to do with the way your husband acts. In fact, creatine is found in read meat, so after a big steak at a steakhouse does he go crazy to? I think you need to ask him what else he’s been taking :)

I’m 14 and want more muscle will creatine hurt me in any way shape or form?

Daniel Kim - 20 Mar 09 at 13:37:02

Does Creatine stimulate the increase of hormones? I have Six Star Muscle Fuel Creatine and was wondering if its advanced than a lot of other creatine types?

Money - 03 May 09 at 22:10:43

Yo. I’m 15 years old and I’m trying to get big. I workout three days a week *Monday-Wednesday-Friday*. If I take a table spoon of creatine everyday I workout, will I have any sexual side effects? Or any side effects at all?

Some of my freinds told me that it messes with your reproduction system, and I wouldn’t be able to have kids.

weegee - 04 May 09 at 04:14:33

Hi, What is better supplement for me to take a whey protein powder or creatine? I go to the gym 3-4 times a week and my goal is muscle mass. What do you recommend for me?

Joel - 31 May 09 at 06:57:51

I’m in the same basket as most of the 15-16 yr olds on this page. Will this have any negatove effects on a 15 yr old?

sara - 05 Jun 09 at 13:57:18

I was just wondering do you have to work out every day when you start taking creatine? How will my diet change or just eat the same?

stephen - 21 Jun 09 at 06:48:20

im 14 can i take creatine

Jay Biz - 16 Feb 13 at 21:50:32

The first creatine i used was called cell-tech back in the day….11 pounds in 7 days, fully bloated but also was lifting more. The problem I ran into was as soon as I stopped the “loading phase”, weight dropped and so did strength. The Creatine 3X Elite from Dr Max Powers seems to be the best creatine I have ever bought online for long term strength gains which I keep even after getting off of it completely.
