DL-Phenylalanine possesses many health benefits such as pain and mood management. It also heightens overall awareness and regulates one’s appetite. It can be used as a component in the synthesis of many different proteins that are naturally produced in the body. These pain-relieving effects that DL-Phenylalanine possesses are believed to be connected to its ability to produce endorphins in the brain, natural opiates that the body produces on its own.Phenylalanine is converted into Tyrosine in the body, which is another type of amino acid that creates proteins, hormones of the thyroid and various other chemicals in the brain. In addition, it helps create the neurotransmitters Norepinephrine, Epinephrine, and Dopamine that are needed to send signals from one nerve cell to the next.It is suggested that DL-Phenylalanine be consumed in servings of 375mg (roughly 1/4 tsp), to be taken three to four times per day, depending on intended effect. As a caution, it should be noted that sometimes it can take upwards of four weeks for the effects of DLPA to be noticeable.
