I was wondering what would be the best creatine for me. My body didn't take good to. It dehydrated me even after I drank two gallons of water. I tried taking it with milk as well as orange juice. The guy at GNC recommended that I take this specific kind of creatine. I forgot which type he said it was, I just remember he said it was the most absorbent. Also, I'm just wondering how important is creatine? I've just stayed clear of it ever since I woke up dehydrated, because I don't want to go through that again. I had bad headaches with it too and even after drinking water the headaches would not go away. Please keep in mind I drank well over the amount of water that was suggested on the label. I was drinking a gallon and a half to two gallons of water.
