Amino acids question?!
Question: I have purchased both L-phehylalanine and L-Tyrosine. I now read that the L-Phenalyanine converts to tyrosine. Is there any reason to take the first in that case?

They have different uses and not all phenylalanine is converted. If you eat a balanced diet there is no need for you to be taking these supplements anyway. :-)
Phenylalanine
Phenylalanine is an essential amino acid that is needed for normal functioning of the central nervous system. It has been used successfully to help control symptoms of depression and chronic pain, as well as other diseases linked to a malfunctioning central nervous system.
Phenylalanine is especially effective for treating brain disorders because it is able to penetrate the blood-brain barrier. The blood-brain barrier is a protective barrier formed by the red blood cells and the glia of the brain that protects the brain from any toxins, bacteria, and viruses, etc., that are circulating through the bloodstream. Only chemicals that are able to cross this barrier can directly affect brain function.
The body needs phenylalanine to make epinephrine, dopamine, and norepinephrine, three neurotransmitters that basically control the way you perceive and interact with your environment. Phenylalanine supplementation may help you feel happier, less hungry and more alert; it has also to treat chronic pain and improve memory and concentration. Recent research indicates that phenylalanine, which aids in melatonin production, may be effective for treatment of vitiligo, a condition that causes white patches on the skin. Subjects treated by these researchers took 50 to 100 milligrams oral L-phenylalanine and applied topical 10 percent phenylalanine gel each day and reported an average improvement rate of 83 percent.
There are three different kinds of phenylalanine: L-phenylalanine, D-phenylalanine, and DL-phenylalanine. Each type of phenylalanine is used to treat different symptoms. D-phenylalanine is more effective for controlling pain, while L-phenylalanine is more effective for regulating mood, appetite, and mental alertness; DL-phenylalanine affects both pain sensitivity and mental state.
Phenylalanine is an essential amino acid, which means it must be obtained from dietary sources. People that suffer from arthritis, obesity, severe menstrual cramps or mild depression may want to speak to their doctor about trying phenylalanine supplementation. Phenylalanine supplements come in capsule, tablet, and powder form. Phenylalanine has also been used to treat Parkinson
