  • Tryptophan is a natural building block of serotonin, the neurotransmitter that plays an important role in satiety, mood, normal sleep patterns, and nervous-system function.*

    There are two vastly different approaches to making your body think it has more serotonin: one is to mimic it, the other is to make it.*

    With LIDTKE® L-Tryptophan there really is no better, no more-natural way to help feel relaxed.*

    Intended to support:

    • Relaxation and sleep*

    • A calm mood*

    • Satiety*
