Creatine is not a sugar and it doesn't work by making you bloated. Some of the creatine products contain CHO, but unless it is 50 + grams, it is unlikely to have much effect enhancing creatine uptake.
The water retention experienced by some may add a mechanical advantage but the primary mechanism is an increase in intramuscular Cr and PCr, and some La buffering that over the long run will help build muscle/strength because of increased mechanical loading from the extra rep or two.
Until I see a paper on other forms of creatine, particuarly the creatine titrate that is ill defined (chemical formula) by the mfgs, I'd stay with creatine monohydrate, just watch the dosing and take it with food and plenty of water. A substance that sits in the small intestine can draw water out of the small intestine and cause osmotic diarrhea. Taking it with food to slow the amount in the small intestine per unit time should help.
If the creatine doesn't cause water retention, I question how much creatine per se is in the product. That was one of the selling points of liquid creatine and the reason it didn't cause water retention was because it was mostly creatinine by the time you ingested it.
Could be that some of these other products are a creatine salt and 5 grams only equals about 2 - 3 grams per dose. Remember a water molecule added to creatine accounts for less of the total weight per dose than citrate or another salt. Just do the math.
