Creatine Monohydrate is basically creatine bound with water. Each molecule of creatine monohydrate is made up of 88% creatine and 12% water. Or to put it another way - 1 gram of creatine monohydrate has 880 milligrams of creatine. This means that if you take 5 grams of creatine monohydrate you will really be putting 4.40 grams of creatine in your body. Creatine Monohydrate is by far the most common form for a creatine supplement. The majority of studies and research have been conducted using creatine monohydrate.
Creatine monohydrate was the first creatine supplement available and is still the least expensive form of creatine. Most people respond well to this basic creatine powder, although some people experience bloating, diarrhea or cramps. This is usually caused by forms of creatine that have not been ground into a fine enough powder. Almost all brands of creatine monohydrate on the shelves today is micronized creatine, which is an easily mixed fine powder. If you decide to stick with creatine monohydrate, be sure that it is the micronized version. This is the type of creatine that I use and it works great for me, and it is cheap!
