    Do not take tryptophan (also called L-tryptophan) if you're pregnant. It can cause serious breathing problems for your fetus.

    Tryptophan was linked to the outbreak of a serious neurological condition that led to a number of deaths in 1989. It was temporarily banned. Although it is once again available, it is still considered possibly unsafe.
