Tryptophan

Your body cannot produce tryptophan naturally, so it must be obtained through diet and supplements. Tryptophan affects the levels of the neurotransmitter serotonin, which is responsible for your mood and sleep-wake cycles. Supplements containing tryptophan may help individuals experiencing insomnia or depression.
