It's much easier to get dehydrated when taking creatine. Taking too much is also harder on your kidneys.Nothing really I just put it in the same shake as my protein.
Since taking 5 grams a day it's been a lot better. I feel like the loading phase was a waste because I was losing a lot of water from the runs. Kinda disappointed from the advice that was given to me.
Thinking back, if some teen took it and didn't know that they were losing lots of water from the runs it could be pretty dangerous...
Years ago Prolab Creatine would give me the runs even on a 5g dose. Something about that brand. Since then I've taken numerous different labels of certified Creapure Creatine and never had an issue. Maybe you're having the same issue.
The reason i asked if your creatine had anything else in it is that some had added fillers and one of those could have been upsetting your stomach in larger doses.
