L-Phenylalanine - Nervous system support
Phenylalanine (LPA) is an essential amino acid that cannot be synthesised in the body and must be derived from the diet. For complete utilisation of dietary protein in the synthesis of tissue proteins and growth, daily intake should be 2.8 grams per 100gm of dietary protein.
L-Phenylalanine and Tyrosine Production
Phenylalanine is the major precursor of the amino acid tyrosine. This, in turn, is the precursor of many important chemicals in the body, including the neurotransmitters adrenaline and noradrenaline, the thyroid hormone thyroxin and the pigment melanin. It has also been used in preparations marketed as smart drugs. The basis for this use is probably the elevation of neurotransmitters in the brain. LPA can also be converted (through a separate pathway) to phenylethylamine, a substance that occurs naturally in the brain and appears to elevate mood.
D - phenylalanine (DPA) is not normally found in the body and cannot be converted to L-tyrosine, L-dopa, or norepinephrine. As a result, DPA is converted primarily to phenylethylamine (the potential mood elevator). DPA also appears to influence certain chemicals in the brain that relate to pain sensation.
DLPA is a mixture of LPA and its mirror image DPA. DLPA (or the D- or L - form alone) has been used to treat depression. DPA may be helpful for some people with Parkinson's disease and has been used to treat chronic pain-including pain from osteoarthritis and rheumatoid arthritis-with both positive and negative results. No research has evaluated the effectiveness of DLPA on rheumatoid arthritis.
L- phenylalanine has been used for helping with agitation, alcohol withdrawal, appetite control, chronic pain, depression, kidney failure, memory loss, obesity, opiate withdrawal and a poor libido.
