The report however, was only aimed very specifically at POWDERED CREATINE which undoubtedly seems to be an unstable substance as it's mixed separately with water or juice and sometimes even in other beverages. As Creatine powder is highly insoluble, large amounts must be ingested - causing what could mean long-term effects on both the Kidneys and Liver.
This current uncertainty about Creatine in a powder is a reason for what seems to be a current surge in popularity of Serums (Creatine as a liquid) which is highly soluble, thus reaching the muscles faster and apparently 'safer' as the creatine moves in and out of organs faster not being allowed to sit as powders can do. Creatine as a serum also does seem to cause little side-effects - I have rarely heard complaints from it's users and liquid Creatine could be the G O.
Creatine as a liquid also doesn't cause water retention like Powdered Creatine (but is that an advantage?). The same report by France's Agency of Medical Security for Food also found the increase in muscle was largely due to water retention cause by the Powdered Creatine which also poses the question does Creatine actually directly cause you to add muscle or does it just give you that added energy boost. But does creatine even add energy. I've seen several reports showing that people have been fatigued by Creatine although it could be purely coincidental (maybe they were fatigued by training - that's a very logical answer). For most people it is accepted worldwide that the benefits of Creatine (in any form) are substantial, which is the reason why it's been the best supplement (and the safest, till now) to hit our stores ever. It is beginning to become clear that the only effect Creatine has on muscle building is that it allows you to workout longer and harder.
So next time you jump into the Bodybuilding.com store for your monthly supply of Creatine, split it - half powder and half serum and see which one you like better. I think you'll probably find there's not a lot of difference but if you want to feel safe with Creatine stick with liquid Creatine because "the jury ain't out on Creatine yet!".
