What Is DL-Phenylalanine (DLPA)?

DLPA pairs two distinct forms of the amino acid phenylalanine: the D-form and the L-form. L-Phenylalanine, an essential amino acid, builds proteins and serves as a precursor to neurotransmitters like dopamine and norepinephrine, which help support alertness and focus. The D-form, not commonly found in foods, is thought to influence the body's perception of discomfort by interacting with opioid receptors and slowing the breakdown of endorphins and enkephalins. Source Naturals DLPA delivers 750 mg per tablet, making it easy to add this amino acid to your daily regimen.

Manufactured in Scotts Valley, California, under strict Good Manufacturing Practises (cGMPs), each batch is crafted with quality in mind. Source Naturals has been a trusted name for over 35 years, supporting individuals in their pursuit of optimal health.

Who Might Benefit from DLPA?

DLPA may be a valuable addition for healthy adults seeking to support their mood and mental clarity. It can be particularly helpful for those interested in amino acid supplementation for cognitive function or emotional balance. Since phenylalanine is essential, individuals with dietary restrictions or higher metabolic demands may also consider it. As with any supplement, it's wise to consult a healthcare professional before starting DLPA, especially if you are pregnant, nursing, have a condition like phenylketonuria (PKU), or take medications that affect neurotransmitter levels.

Key Benefits of DLPA Supplementation

DLPA is often used to help maintain a positive mood and comfort levels. By potentially extending the life span of endorphins and enkephalins—the body's natural feel-good compounds—DLPA may support a sense of wellbeing. Additionally, L-phenylalanine acts as a precursor to neurotransmitters that promote alertness, potentially contributing to mental focus and clarity. Individual results may vary, and DLPA is not intended to diagnose, treat, , or prevent any disease.

Top Ingredients to Look For

The primary ingredient in a DLPA supplement is DL-Phenylalanine. Purity and sourcing matter—choose products that specify both the D and L forms and avoid unnecessary fillers. Some supplements include additional nutrients like vitamin B6 or vitamin C to aid amino acid metabolism, but Source Naturals DLPA focuses on a high dose of DLPA alone, allowing precise dosing. Always check the label for allergen information to ensure it meets your dietary needs.

Frequently Asked Questions About DLPA

What is the difference between DLPA and L-Phenylalanine?

L-Phenylalanine is the natural form found in food and the body, essential for protein synthesis and neurotransmitter production. DLPA combines L-Phenylalanine with D-Phenylalanine, a synthetic form that may influence endorphin activity, offering a broader range of potential benefits.

Can DLPA help with mood?

By serving as a precursor to dopamine and norepinephrine, L-Phenylalanine may support alertness and a positive mood. The D-form may further contribute by prolonging the effects of endorphins. Many people use DLPA to maintain emotional balance, though individual experiences vary.

How should I take DLPA?

The typical dosage is 750 mg (1 tablet) taken 1 to 3 times daily, preferably on an empty stomach for optimal absorption. Start with the lowest dose to assess tolerance, and adjust as needed under professional guidance.

Are there any side effects?

DLPA is generally well-tolerated, but some individuals may experience mild digestive upset or restlessness, especially at higher doses. Those with phenylketonuria (PKU) or high blood pressure should avoid DLPA without medical advice.
