Now Foods L-Phenylalanine. This free form amino acid can serves as a building block in the body for the production of various proteins. This amino acid can be converted to L-tyrosine and subsequently to L-dopa, norepinephrine epinephrine. nervous system support. Supports a positive mood. Free-Form. 500mg.
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.

People with high blood pressure should only take L Phenylalanine after meals, and only after seeking advice from their health care professional.
L-Phenylalanine 500mg supplies a free-form essential amino acid that the body uses as a building block for proteins. L-phenylalanine can also be converted into tyrosine, which is then used to make compounds involved in normal neurotransmitter function.
That is why L-phenylalanine is often used in products aimed at mood, motivation and mental focus support. This product keeps things simple by providing the amino acid on its own, without caffeine, herbs or extra vitamins added.
What is L-phenylalanine commonly used for?
L-phenylalanine is commonly used for nervous system and mental performance support because it is involved upstream in the production of important brain chemicals.
How is L-phenylalanine related to tyrosine?
The body can convert phenylalanine into tyrosine, which is another amino acid used to make neurotransmitters.
What should I know before buying L-Phenylalanine 500mg?
This is a single-amino-acid product, so it is best suited to you if phenylalanine is the specific ingredient you want rather than a blended focus formula.
