L-Phenylalanine Powder - Essential Amino Acid Supplement, 500mg per Serving, Gluten-free, 250g

Benefits of L-Phenylalanine Supplementation

L-phenylalanine acts as a precursor for tyrosine, which is then used to produce catecholamines—dopamine, norepinephrine, and epinephrine. These neurotransmitters are vital for maintaining focus, energy, and a healthy stress response. Supplementing with L-phenylalanine may therefore contribute to normal neurotransmission and cognitive function. Furthermore, as an essential amino acid, it supports protein synthesis, aiding muscle maintenance and recovery. Many active individuals find it beneficial for energy metabolism.

How L-Phenylalanine Functions

Upon ingestion, the body converts L-phenylalanine into L-tyrosine through the action of phenylalanine hydroxylase. Tyrosine subsequently forms catecholamines, which are crucial for alertness and energy regulation. This pathway is fundamental for normal nervous system function. As an essential amino acid that cannot be produced internally, supplementation helps maintain optimal levels, particularly for those with dietary limitations or heightened physical demands.

What Is L-Phenylalanine?

L-phenylalanine is one of the nine essential amino acids, meaning the body cannot synthesise it from other compounds. Dietary sources or supplements are necessary to meet your requirements. As a fundamental component of proteins, it contributes to numerous bodily functions. This pure powder delivers 500 mg per serving, allowing flexible integration into your regimen. For both athletes and those prioritising general wellness, maintaining adequate L-phenylalanine levels supports neurotransmitter balance, influencing mood and mental clarity.

Usage Guidelines

The powder form provides versatility. Simply mix one 500 mg scoop into water, juice, or a smoothie. For optimal absorption, take it on an empty stomach around 30 minutes before meals or exercise. Begin with one serving per day and adjust according to your needs. Since L-phenylalanine can affect neurotransmitter activity, avoid late-night consumption if you are sensitive to stimulation. Regular uses helps maintain stable amino acid concentrations.

Safety and Dosage Advice

L-phenylalanine is generally well tolerated at standard doses. A typical serving is 500 mg, whilst some may take up to 1000 mg daily. Do not exceed the recommended intake without professional advice. Those with phenylketonuria (PKU), a condition that impairs phenylalanine metabolism, must avoid this product. Pregnant or breastfeeding women and individuals taking MAO inhibitors should consult a health care practitioner before uses. Discontinue if adverse effects occur and keep out of children's reach.
