L-Tryptophan is the amino acid most lacking in the American diet and probably the amino acid most critical to emotional health and normal, refreshing sleep.
But there is more. Science now demonstrates that serotonin helps convert stem cells into neurons that enhance memory and cognition. Animal studies found even small amounts of L-Tryptophan improve learning, memory and long-term retention.
L-Tryptophan is a natural building block of serotonin, the neurotransmitter that plays an important role in appetite, mood, normal sleep patterns, and nervous-system health.* When your body needs extra help producing serotonin for peaceful sleep and a more relaxed outlook, choose LIDTKE L-Tryptophan.*
