Predominantly Coffee, I never had anything but Asparagus smell in my urine pre-CFS but now I can smell quite distinctly varying smells in my urine. Coffee in particular smells almost exactly the same as if it was poured from the pot! Yet the colour of my urine can be normal.....
....Could this be a smoking gun? Poor liver and kidney function?
I only have an ammonia smell if I have taken protein and my vit mB12 supplement but forgot to take phosphatidylserine which helps the cell to usher things away through normal waste channels (it's part of the homocysteine cycle, in the methylation cycles). Now they dump the ammonia directly in my urine.
Colour is normal. Smell goes away when I take phosphatidylserine. I'm not worried.
Does coffee have proteins?
Either way: if colour is light then kidneys are allright, is what I assume.
If your stool is darkly coloured then that channel of waste elimination is working correctly too. Dark means bile and bile is the chief waste vessel of your body for the heavy bad things (hormones, toxins). Metals go through sweat, so that's the third way.
