After careful consideration, we have decided to discontinue DL-Phenylalanine (SA550). The lack of demand for the product no longer justifies continued production. We recommend the amino acid L-Tyrosine as an alternative.
important neurotransmitter precursor*
Phenylalanine (DLPA) is a biologically essential amino acid that is a precursor to tyrosine and the catecholamine neurotransmitters dopamine, norepinephrine, and epinephrine. DLPA is involved in protein synthesis and regulation.* In addition to DLPA's role as a precursor to the catecholamines, it is present in several active brain compounds that have a multitude of functions.* DLPA has the potential to increase endorphin and enkephalin (opioid compounds) levels in the central nervous system.* Clinical studies demonstrate a mood-balancing effect after taking DLPA.*
