I have searched for a definitive answer to this question on google but found conflicting opinions. My question and situation is as follows:

I am traveling from Ithaca, NY to Detroit, MI and back later this month. I am a big fan of weightlifting and am staying in Ann Arbor, MI to work in U Michigan Ann Arbor for a few days. I intend to buy a week pass to the gym and do some powerlifting in addition to work.

I am wondering if I could bring a zip lock bag of whey protein powder with me as part of my carry on and if anyone has had any similar experiences regarding this situation.

Yes, you are fine bringing a bag of protein powder in your carry-on. The TSA requires food (which it would probably be considered) to be wrapped and to be sent through the X-ray machine at the security checkpoint, but so long as it is not a liquid or gel it isn't banned.

Note that, especially since it won't be in its original container, they may want to sample it for testing. The same goes for any powder (e.g. powder makeup, sugar, dietary fiber supplements, talcum, Gatorade). It goes without saying that powders which are hazardous materials (e.g. explosive or corrosive) are banned of course.
