Key Benefits of DL-Phenylalanine

DL-Phenylalanine combines two forms of the essential amino acid phenylalanine to support mood, focus, and stress resilience. L-phenylalanine acts as a precursor to tyrosine, aiding production of dopamine, norepinephrine, and epinephrine. D-phenylalanine may help maintain healthy endorphin levels by inhibiting their breakdown. Together, they promote a positive mood and mental clarity. Each capsule provides 500 mg of this unique blend for convenient daily support.

What Is DL-Phenylalanine?

This supplement contains a balanced mix of L-phenylalanine and D-phenylalanine. L-phenylalanine occurs naturally in protein-rich foods and is essential for neurotransmitter synthesis, while D-phenylalanine is a synthetic form that works via different pathways. The 500 mg capsule delivers both to offer broad-spectrum support for your body's natural processes.

Who Should Take DL-Phenylalanine?

Ideal for individuals seeking natural support for mood balance, cognitive function, and healthy stress responses. It may also be used by those looking to manage occasional discomfort after physical activity. As with any supplement, consult a health care professional to see if it fits your wellness routine.

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 health care provider. Each bottle contains 100 capsules – a 100-day supply at the recommended serving. Store in a cool, dry place away from direct sunlight.
