Life Extension D,L-Phenylalanine 500mg – 100 Vegetarian Capsules

Life Extension D,L-Phenylalanine 500mg provides a balanced amino acid formula designed to support healthy neurotransmitter synthesis, positive mood and cognitive wellness. Phenylalanine is an essential amino acid, meaning that the body must obtain it from food or nutritional supplementation rather than producing sufficient amounts independently. This formula combines equal proportions of D-phenylalanine and L-phenylalanine in one vegetarian capsule, creating the 50/50 mixture commonly known as DLPA. With 500 mg per capsule and a convenient 100-day supply, it is intended for adults seeking focused amino acid support within a balanced lifestyle, without positioning the product as a treatment for depression, chronic pain, sleep disorders or another medical condition.

The Science of D,L-Phenylalanine Optimization

Phenylalanine participates in pathways connected with protein synthesis and neurotransmitter production. The L-form can be converted to L-tyrosine, which serves as a precursor for catecholamine neurotransmitters including dopamine, norepinephrine and epinephrine. The D-form has a different metabolic profile and is included alongside the L-form in this balanced DLPA formula. Tyrosine Precursor Pathway: L-phenylalanine can be converted in the liver into L-tyrosine. Tyrosine then provides a nutritional building block used within the regulated pathways that produce dopamine, norepinephrine and epinephrine. Catecholamine Support: Dopamine and norepinephrine participate in normal motivation, attention, reward and mood-related signaling. Providing a precursor does not guarantee a specific psychological effect, because neurotransmitter synthesis remains controlled by enzymes, co-factors and individual nutritional status. Co-Factor Synergy: Vitamins B6 and C participate in enzyme systems connected with catecholamine metabolism. Life Extension therefore recommends taking the product within a routine that provides adequate amounts of these nutritional co-factors.

Usage Guide

Take one vegetarian capsule daily on an empty stomach in the morning, or follow the recommendation of a qualified healthcare practitioner. Life Extension states that the formula may be best utilized when the nutritional co-factors vitamins B6 and C are adequately available. Avoid taking the capsule at the same time as a high-protein meal or another concentrated amino acid formula unless professionally advised, because amino acids can compete during absorption and transport. Do not exceed the stated serving, and use the product as part of a varied diet and balanced wellness routine.

Safety Information

Do not use this product if you have phenylketonuria or another condition requiring restricted phenylalanine intake. Phenylalanine-related pathways can influence norepinephrine and epinephrine production, so people with high blood pressure or cardiovascular concerns should obtain medical guidance before use. Consult a physician if you are pregnant, breastfeeding, receiving medical treatment or taking prescription medication, especially levodopa, monoamine oxidase inhibitors, stimulant medicines or psychiatric treatments. Do not use the supplement as a substitute for professional care for depression, pain, attention problems or another condition. Stop use and seek advice if unusual agitation, headache, palpitations, increased blood pressure or another unexpected response occurs.
