L-Phenylalanine - Douglas Laboratories
amazon.co.uk
DESCRIPTION This supplement provides 500 mg of L-phenylalanine in pure form per capsule. FUNCTIONS L-Phenylalanine is an essential amino acid that must be obtained through a proper diet. It is mainly found in protein-rich sources such as meat and eggs, which plays an important role in regulating the nervous system. L-phenylalanine is metabolized and generates two different chemicals, phenylethylamine and tyrosine. Phenylethylamine is a neuroamino which can cause effects on mood and feelings. Tyrosine is an important amino acid precursor of certain neurotransmitters, such as dopamine, epinephrine (adrenaline) and norepinephrine (noradrenaline). The synthesis of these neurotransmitters is limited by the input speed of tyrosine from plasma into the brain. L-Tyrosine is a conditionally essential amino acid which can be manufactured by the body from essential amino acid phenylalanine. Therefore, adequate tyrosine production depends on an adequate supply of phenylalanine in the diet. INDICATIONS L-Phenylalanine may be a useful dietary supplement for those who follow a vegetarian diet, or perform as strenuous sports. It can also be a good supplement for those suffering from sleep disorders. FORMULA Each Capsule contains: L-Phenylalanine ..................................... 500mg SUGGESTED USE Adults take 1 capsule daily or as directed by healthcare provider. Precautions: Do not take during pregnancy or breastfeeding. Do not exceed stated recommended daily dose. SECONDARY EFFECTS Warning: PHENYLKETONURICS: contains phenylalanine.

Phenylalanine 60 caps
amazon.co.uk
Okygen Sports Phenylalanine - Improve metabolism regulation and enhance your mood and overall health with this essential amino acid. Phenylalanine is an amino acid that the body must obtain through food intake, since we cannot produce it internally, and that is why it is called an essential amino acid. Phenylalanine is one of the building blocks of proteins and it is an important element to restoring and renovating biological structures, like our enzymes, blood, muscles, tendons, ligaments, body organs and glands. Like other amino acids, phenylalanine consumption is essential to keep our muscles healthy and strong, because it helps regenerate damaged muscle tissue, something that frequently happens in people practicing strenuous activities that require power endurance, such as weightlifting. Being one of the essential amino acids in protein, phenylalanine is a key element in muscle recovery and development. Phenylalanine is also a precursor to tyrosine and, once in the body, it is converted into tyrosine. Subsequently, tyrosine is converted into important neurotransmitters, such as dopamine, norepinephrine, and epinephrine, as well as into thyroid hormones. These hormones and neurotransmitters influence growth and development, mood, sexual function, reproduction, movement, memory, attention and problem solving. They also enhance motivation, &amp;ldquo;fight or flight&amp;rdquo; response, heart rate, and energy production...  read more

Quest L-phenylalanine 500mg - 30 Capsules
amazon.co.uk
DescriptionPhenylalanine is an essential amino acid that is needed for normal functioning of the central nervous system. It has been used successfully to help control symptoms of depression and chronic pain, as well as other diseases linked to a malfunctioning central nervous system.The body needs phenylalanine to make epinephrine, dopamine, and norepinephrine, three neurotransmitters that basically control the way you perceive and interact with your environment. Phenylalanine supplementation may help you feel happier, less hungry and more alert; it has also to treat chronic pain and improve memory and concentration. Recent research indicates that phenylalanine, which aids in melatonin production, may be effective for treatment of vitiligo, a condition that causes white patches on the skin. There are three different kinds of phenylalanine: L-phenylalanine, D-phenylalanine, and DL-phenylalanine. Each type of phenylalanine is used to treat different symptoms. D-phenylalanine is more effective for controlling pain, while L-phenylalanine is more effective for regulating mood, appetite, and mental alertness; DL-phenylalanine affects both pain sensitivity and mental state.

L-Phenylalanine 500 mg 60 cap
amazon.co.uk
Prozis Sport L-Phenylalanine 500mg - Regulate your metabolism and improve your mood and cognitive functions. L-Phenylalanine is an essential amino acid that the body needs to keep its normal functioning. Essential amino acids have this name because it is essential that we include them in our daily diet, since the body does not produce them naturally. L-Phenylalanine is necessary for the overall health of the human body. Once in the body, this amino acid is transformed into another amino acid, tyrosine. Then, tyrosine is synthesized into three key neurotransmitters, which are dopamine, norepinephrine, and epinephrine. Neurotransmitters are chemicals that transmit signals between nerve cells, and they are absolutely crucial in the mechanisms that regulate our cognitive function and our mood. L-Phenylalanine has been shown to raise the production of neurotransmitters and feel-good hormones by the pituitary gland. These chemicals have the ability to improve your mood, protecting you from feelings of depression and low self-esteem. Due to the role they play in the brain, they can also enhance several specific mental functions, such as focus, acuity, memory, movement, and problem-solving skills. Since this unique amino acid has the ability to cross the blood-brain barrier and increase the production of neurotransmitters, L-Phenylalanine can improve all these brain functions, contributing to enhance your menta...  read more

D, L - Phenylalanine 500 Mg - 100 Caps
amazon.co.uk
D,L-Phenylalanine Capsules 500 mg, 100 capsules Item Catalog Number: 034 L-Phenylalanine/L-Tyrosine L-phenylalanine is an essential amino acid, which can be converted to L-tyrosine by a complex biochemical process which takes place in the liver. L-tyrosine can be converted by neurons in the brain to dopamine and norepinephrine (noradrenaline), hormones, which are depleted by stress, overwork and certain drugs. By replenishing norepinephrine in the brain, mental energy levels are enhanced and a feeling of contentment often occurs. Because of the liver conversion necessary for L-phenylalanine to have these effects, L-tyrosine is often faster acting. In addition, the conversion step from L-tyrosine to norepinephrine may be enhanced if the cofactors (vitamins B6 and C) are included.* Some of the norepinephrine will also be converted to epinephrine (adrenaline) in the brains adrenal medulla by use of S-adenosylmethionine (SAMe) as a methylating agent. Since both norepinephrine and epinephrine can cause smooth muscle (arterial) contraction, care with blood pressure should be taken when supplementing L-phenylalanine or L-tyrosine.* L-tyrosine is also a precursor of two thyroid hormones. D-phenylalanine is unique among amino acids because the D-form (normally not found in life) has biological activity that is different from its L-stereoisomer. D,L-phenylalanine is a 50/50 mixture of the two stereoisomers. Supplement Facts Serving Size 1 capsule Servings Per Container 100 Amount Per Serving D,L-Phenylalanine 500 mg Other ingredients: magnesium stearate, gelatin, and water. Dosage and Use - Suggested dose is 500 to 1000 mg in the morning or afternoon. - More may be necessary for increasing the feeling of well-being. - These products are most effectively utilized when taken on an empty stomach mixed with juice or water. - Adequate co-factors (vitamins B6 and C) should also be taken if not included with the p  read more
