Function:
L-Tryptophan is a natural anti-depressant, plentiful in protein foods but largely lost through cooking and processing.
L-Tryptophan is a naturally occurring amino-acid. It is a precursor for the mood-regulating serotonin the brain neurotransmitter linked with pleasure and fulfilment.
L-Tryptophan's is used to alleviate depression, support alcohol withdrawal and to aid weight loss. It plays an important role in our diets, and aging individuals are often in need of it as a supplement.
