I don't know if higher level staff ever read the board, but I'm curious why, after years, ProHealth is discontinuing the sale of this supplement that helps me immensely . I was on automatic order and got a notice that I would begin receiving tryptophan instead. I called to cancel that and the gal I spoke to kept trying to assure me that this was just as good. I'm not posting to say tryptophan isn't good, but to protest that these are two different supplements that work in two different ways and line staff and the catalogue shouldn't be inferring that they act the same. I couldn't get through to anyone with any knowledge about the switch on the phone so hope I will here. Thanks.
