[edit] Side Effects... For Real

This article needs to list side effects, and sources for the list of side effects. As is, this article would lead individuals to believe there are no side effects. This is not true. This is most likely due to Supplement companies contributing a lot of this article, most likely the ones named in the article. Muscletech is notorious for trolling sites and forums attempting to better themselves and their overpriced products, regardless, within a week or so someone should post the well documented side effects of creatine, or I'll write up a list of the side effects mentioned in documents from the Mayo Clinic.

Chk this:

"Current studies indicate that short-term creatine supplementation in healthy individuals is safe (Robinson et al., 2000). Longer-term studies have occasionally been done, but have been small. One such study that is often cited involved a minimum length of 3 months, but only had 10 creatine subjects (Mayhew et al 2002)."

Robinson et al., 2000/Mayhew et al 2002 is not proper documentation for a wikipedia article.

It's been well-documented that the many scientific studies of creatine have found no deleterious effects or medical risk, and in fact the only side effect from creatine supplementation reported in the scientific and medical literature has been weight gain. Negative side effects are generally isolated anecdotal reports. I don't see how the article is misleading or contains trolling. I'll leave you with this PDF ^[1] to read.

Have removed this rubbish "causes large ejaculation from penis sometimes up to a gallon of fluids". ozboy 5/10/06

I don't have any studies handy, but it has been my understanding (and personal experience) that using creatine monohydrate supplements can cause or worsen acne. In a brief glance at various online message boards, this seems to be a fairly common side effect. Worth mentioning in the article? KyuzoGator 18:03, 28 March 2007 (UTC)

Only if it's referenced - try www.pubmed.com for any studies that detail side-effects. Frankg 19:05, 28 March 2007 (UTC)

[edit] References

This link [2] needs to be added to the list of references at the bottom of the article. If anyone spots any other studies cited that aren't at the bottom, please add them. Thanks. Yankees76 17:42, 22 August 2006 (UTC)

[edit] Someone should add...

Someone should add that Creatine is not an anabolic steroid and has no relation to anabolic steroids. This seems to be one of the most common misconceptions concerning creatine in the public that I know of. As absurd as it is. I think it atleast belongs here somewhere.

I agree with this opinion. I had the above misconception. I found the following article to be an interesting source: http://www.quackwatch.org/01QuackeryRelatedTopics/DSH/creatine.html .

[edit] Side effects?

How about adding the list of other effects recognized by the FDA (and some indication of how likely they are), and the foul body odor that creatine users are notorious for having?

Got a source for that? Yankees76 15:20, 16 October 2006 (UTC)

For the body odor thing? Not a rigorous study. But the lead author of an article about creatine effects on brain function (C Rae, AL Digney, SR McEwan, TC Bates. Oral creatine monohydrate supplementation improves brain performance: a double-blind, placebo-controlled, cross-over trial. Proc. Royal Soc. B. 270/1529 (October 22, 2003), 2147-2150) has said in interviews that it makes its users smell worse. She'd be about as authoritative as it gets until there's a specific study on whether creatine makes body odor stronger, and who would fund that? Anecdotal sources and assertions spring up on a google search for <creatine "body odor">. The BBC published the statement too when reporting about the aforementioned article.

[edit] Clearance of Creatine and NCAA rules?

Can anyone tell me, how long does it take to clear creatine from your system....i.e. can you take it for a brief period and get benefits but not have it show up on drug test for a college athlete. Does anyone know if it is forbidden by the NCAA rules?

4-6 weeks, but it's not banned by the NCAA, so they're not testing for it. Yankees76 04:22, 8 February 2007 (UTC)

[edit] information request on creatine blockers

bill are there creatine blockers or inhibitors? itd be interesting to know if there are, i had a conversation with a guy last week who claimed that coffee is a creatine inhibitor. is there documented evidence of this? —The preceding unsigned comment was added by Billleo74 (talk • contribs) 16:51, 28 January 2007 (UTC).

Not true. One study Vandenberghe in 1996 "showed" that creatine and creatine/caffeine supplementation completely negated the performance benefits of creatine in this study. However the study is commonly dismissed and is better known in the supplment industry for it's flawed design.

First it incorporated what is called a "crossover design". In this type of study, one group takes creatine and then switches to a placebo a few weeks later while other group does the opposite. During each treatment performance tests are done. This allows for researchers to compare the same athletes (on creatine) to themselves (on placebo) a few weeks later.

The clowns who did this study only allowed three weeks between creatine / caffeine and placebo. The problem is that creatine, once loaded into the muscle, takes about four to six weeks – or more – to be eliminated.

What is also interesting about the study is that is showed that caffeine didn't affect muscle creatine levels. So if muscle creatine levels remain unhindered by the caffeine, why didn't the athletes improve their performance? Proably flawed design at work again. Since performance tests were conducted, the treatments could have affected both testing periods - making the data from the study almost meaningless. The short "washout" period in this study probably flawed the results allowing the subjects to have been benefitting from creatine supplementation throughout the testing even when they were performing as the placebo group.

[edit] History of Creatine Supplements

The following sentence is unclear: At the time, low-potency creatine supplements were available in Britain, but creatine supplements designed for strength enhancement were not commercially available until 1993 when a company called Experimental and Applied Sciences (EAS) introduced the compound to the sports nutrition market under the name Phosphagen.

The "compound" was not creatine but creatine monohydrate. If no objection, I would like to change the word "compound" to "creatine monohydrate".GetAnabolics 20:02, 12 March 2007 (UTC)
