Pure Encapsulations® DL-Phenylalanine – Combination of D- and L-phenylalanine of tested quality

Additional product information

Pure Encapsulations® DL-Phenylalanine combines the two forms D-phenylalanine and L-phenylalanine in a balanced ratio.

L-phenylalanine is one of the essential amino acids and must be consumed regularly through the diet. It is an important building block of the body's own proteins and serves as a precursor for the formation of the amino acid tyrosine.

Tyrosine, in turn, is required by the body for the production of various messengers and thyroid hormones.

The vegan formula is suitable for targeted supplementation of the amino acid supply.

Properties and benefits

• DL-phenylalanine: Combination of D- and L-phenylalanine.

• Essential amino acid: L-phenylalanine must be consumed through food.

• Protein metabolism: L-phenylalanine is a building block of the body's own proteins.

• Tyrosine formation: L-phenylalanine can be converted into tyrosine in the body.

• Neurotransmitter metabolism: Tyrosine is a precursor of dopamine, noradrenaline, and adrenaline.

• Thyroid hormones: Tyrosine serves as a precursor for their endogenous production.

• Tested quality: Manufactured according to high international quality standards.

• Vegan: Without animal-derived ingredients.

• Gluten-free, lactose-free, and soy-free.

Phenylalanine – An essential amino acid

Phenylalanine is one of the nine essential amino acids for humans.

The body cannot produce essential amino acids in sufficient quantities on its own. They must therefore be consumed regularly through food.

Phenylalanine occurs naturally in protein-rich foods such as meat, fish, eggs, dairy products, legumes, and nuts.

Phenylalanine as a precursor of tyrosine

L-phenylalanine can be converted into L-tyrosine in the liver with the help of the enzyme phenylalanine hydroxylase.

Tyrosine is required for various metabolic processes and is a precursor for the endogenous production of important compounds.

These include:

• Dopamine

• Noradrenaline

• Adrenaline

• Thyroid hormones

The production of these substances is controlled by various endogenous regulatory mechanisms.

L-phenylalanine and D-phenylalanine – What is the difference?

Phenylalanine can occur in two mirror-image forms:

• L-phenylalanine: The natural, protein-forming form that occurs in food and is required for human protein metabolism.

• D-phenylalanine: The mirror-image form that is not considered one of the essential protein-forming amino acids and is studied in terms of its biological properties.

DL-phenylalanine contains both forms as a mixture.

The physiological functions of L-phenylalanine cannot be fully transferred to D-phenylalanine.

Phenylalanine in the diet

Phenylalanine is a component of numerous plant and animal proteins.

The requirement can also be met in a vegetarian and vegan diet through a balanced selection of protein-rich foods.

In case of insufficient amino acid intake, targeted supplementation may be considered.

DL-phenylalanine of tested quality

Pure Encapsulations® DL-Phenylalanine combines D- and L-phenylalanine in a practical capsule form.

Manufacturing is carried out according to controlled quality standards.

The formula is vegan and free from gluten, lactose, and soy.

Important notes

Dietary supplements are not a substitute for a balanced, varied diet and a healthy lifestyle.

Do not exceed the recommended daily intake. Keep out of reach of young children and store in a cool, dry place.

Important for phenylketonuria (PKU): The product contains phenylalanine and is not suitable for people with phenylketonuria unless expressly prescribed by a doctor.

If taking MAO inhibitors, levodopa, or other medications that affect catecholamine metabolism, the use should be discussed with a doctor beforehand.

In case of high blood pressure, cardiovascular diseases, or existing psychiatric conditions, prior medical consultation is advisable.

During pregnancy and breastfeeding, intake is not recommended without medical advice due to insufficient safety data.
