When i eat canned tuna, or chicken....its makes my piss smell horrible, even when im drinkin more than a gallon of water a day. Now i just hold my nose with my free hand!
Alpha Lipoic Acid is sulphur-based. The rank smell is you pissing out what you couldn't immediately use, or couldn't be stored somewhere for future use. And ALA urine always smelled to me more like burnt plastic than ammonia, but maybe your protein consumption - or lack of absorbtion - has to do with it.
ala made my piss smell funky too... but r-alal not so much. usually in the morning you can tell. all i know is B-vitamins make your piss glow in the dark
