DL-Phenylalanine 500 mg 100 Caps

Who Should Take DL-Phenylalanine?

This supplement is ideal for adults seeking natural support for mood balance, cognitive function, and healthy stress responses. It may also aid recovery after physical activity by supporting endorphin levels. Consult your healthcare practitioner to see if DL-Phenylalanine is right for you, especially if you are pregnant, breastfeeding, or have a medical condition.

What Is DL-Phenylalanine?

DL-Phenylalanine combines two forms of the essential amino acid phenylalanine: the naturally occurring L-form and the synthetic D-form. L-phenylalanine is found in protein-rich foods and serves as a building block for neurotransmitters, while D-phenylalanine may help maintain healthy endorphin levels by slowing their breakdown. Each capsule delivers 500 mg of this unique blend for broad-spectrum support.

Key Benefits of DL-Phenylalanine

L-phenylalanine acts as a precursor to tyrosine, supporting the production of dopamine, norepinephrine, and epinephrine—neurotransmitters involved in mood, focus, and stress response. D-phenylalanine may promote a positive mood by supporting endorphin activity. Together, these forms may help maintain mental clarity, emotional wellbeing, and a balanced stress response. Each capsule provides 500 mg of this combined formula.

How to Use DL-Phenylalanine Capsules

Take one capsule daily with water, preferably on an empty stomach for best absorption, or as directed by your healthcare practitioner. Each bottle contains 100 capsules, a 100-day supply at the recommended serving. Store in a cool, dry place away from sunlight.
