Thanks to Laura's post about BMAA and articles cited there, I did some research about zinc. Taking too much can be dangerous, as with most everything, but guess what the symptoms are if you are deficient in zinc?

■white spots or bands under your fingernails
■fatigue
■diarrhea
■reduced sense of taste or smell


Does PD start off as a zinc deficiency and progress from there? Perhaps a zinc-based pill (currently in phase II trials, see Laura's post on BMAA) can help eradicate BMAA for those exposed to it, since there is no "antidote" to BMAA exposure that I have been able to find.
