Supports Healthy Sleep and Mood

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

   LIDTKE TryptoGold® is custom manufactured to surpass the highest European (EP) standards.

   LIDTKE always strives to offer the finest L-Tryptophan available anywhere.

   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.*

   Serotonin has become a goldmine for the makers of patent medicines, but 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 feel relaxed.*


Here is what one of our customers had to say about their experience with our tryptophan:

I ran into a small store in Thatcher, AZ and found your product. I normally used another brand of Tryptophan and they were out. So I bought yours. I tried it and I am hooked! This stuff works great!
