Can Creatine become toxic with long term use?
In truth, nobody knows. Although the body makes only 1-2 grams per day, the odds are good that your body can handle an intake of 5 or more grams per day. Anybody over 200 pounds can take 10 grams quite safely provided that they drink sufficient fluids ( to avoid cramping ). Some people have been taking as much as 20-30 grams a day since it was first available in 1990.
