Protein is normally not detected in the urine. Sometimes a small amount of protein is released into the urine when a person stands up (this condition is called postural proteinuria). Fever, strenuous exercise, normal pregnancy, and some diseases (especially kidney disease) may also cause protein in the urine.
Phil DID YOU HAVE PROTIEN IN URIN i DID LAST YEAR AND WAS TOLD IT WAS COMMON among bodybuilders also it is from heavy workouts the body does not filter all the protien I know you have been training for years and you never had it before!also it is from alot of other things too.
I think that all these supplement companys are saying you need 2 grams per pound of body wieght is nuts!all they want to do is sell ther product!I hardy ever use orals and I had protienurie so going back in a month or two to get checked again.
THE BEST THING ANYONE CAN DO IS ACCURATELY FIGURE OUT THE AMOUNT OF PROTEIN THEY ARE TAKING IN.. many people guess as to what they take and will be surprised as to the amount they really take..300 is not bad..if it really is 300.. it could actaully be higher..but, large doses of 17 aa tabs will eventually make them kidneys scream.. i totaled my protein many times and actually was higher than i guessed.. i try for about 250- 300 a day.. some days maybe a little less but, if everyone takes the time to accurately total the grams up.. i bet your higher than you thought..
