The brain uses protein transmitters to send action specific signals. These are called neurotransmitters. Some common names are Dopamine, Seratonin, and Melatonin. There are many such transmitters and they all have very specific signaling functions. The foundation amino acid that makes all of these is L-Tryptophan.
Your body will convert tryptophan into the neurotransmitters that it needs. Tryptophan deficiencies are associated with depression, insomnia, premenstrual syndrome, bipolar, attention deficit, and autism-spectrum disorders.
Specifically for sleep the Tryptophan is converted into Seratonin letting the brain relax.
We need deep rapid eye movement sleep – dream sleep so the brain can rest and repair. If we do not get into this deep sleep we can exhaust the brain leading to dysfunction.
The next part of the solution is using the purest Tryptophan made. We want only the highest quality pharmaceutical – grade L -Tryptophan for optimal absorption and usage.
