Is DL-phenylalanine the same as L-phenylalanine?
Phenylalanine is an amino acid, a “building block” of protein. There are three forms of phenylalanine: D-phenylalanine, L-phenylalanine, and the mix made in the laboratory called DL-phenylalanine.
What is L-phenylalanine good for?
Your body uses L-phenylalanine to make proteins and other important molecules. It has also been studied as a treatment for several medical conditions, including skin disorders and depression (2).
When should you take L-phenylalanine?
LPA has been used in amounts up to 3.5 grams per day. For best results, phenylalanine should be taken between meals, because the protein present in food can interfere with the uptake of phenylalanine into the brain, potentially reducing its effect.

What is the role of DL phenylalanine in human body?
The mechanism of DL -phenylalanine’s supposed antidepressant activity may be accounted for by the precursor role of L -phenylalanine in the synthesis of the neurotransmitters norepinephrine and dopamine. Elevated brain levels of norepinephrine and dopamine are thought to have an antidepressant effect.
What are the different forms of phenylalanine?
L-phenylalanine is an essential amino acid. It’s also found in protein in the foods we eat.
