^ If it's not absorbed it floats around in the bloodstream until the kidneys filter it out. That puts extra stress on a very important function of your body.
You seem rather certain that 5-HTP can NEVER have negative effects, no matter when you take it. That is rather foolish, IMO. Plenty of people have reported that 5-HTP dulls their roll, and others have had to go to the hospital to be treated for Serotonin Syndrome. 5-HTP is NOT in our BODIES, I've said this many times before.... it's only found in the brain, and it's bioavailability when taken unnaturally is SHIT. This means much of it is wasted, being filtered out before it ever reaches the parts that matter.
Kind of childish.. "prove it!". Can you prove that 5-HTP is safe for everyone, all of the time?
