Analysis

This Nutricost L-Phenylalanine supplement offers a standard 500mg dose of the amino acid, positioned to support mood, brain health, and mental focus, similar to its counterparts. With 180 servings, it provides a larger supply per bottle compared to many competitors, characteristic of Nutricost's budget-friendly approach. Although its review count is modest, the direct formulation ensures a focused benefit for L-Phenylalanine supplementation.

Pros
  • Standard and effective 500mg dosage of L-Phenylalanine per capsule.
  • High number of servings per bottle (180), indicating good long-term value for the consumer.
  • Directly targets the stated goals of mood support, brain health, and mental focus effectively.
  • Nutricost is known for providing essential supplements at competitive price points.
Cons
  • No explicit price or price per serving provided in the data, making direct financial value comparison challenging.
  • Lower review count (153) compared to more established brands, which might suggest less market presence or newer listing.
  • As a single ingredient, it lacks synergistic cofactors that could enhance L-Phenylalanine's effects or provide broader brain support.
Warnings
  • Individuals diagnosed with phenylketonuria (PKU) must avoid L-Phenylalanine due to their inability to metabolize it.
  • Potential interactions with certain medications, particularly MAOIs and some antipsychotic drugs; medical consultation is advised.
  • Consumption of high doses may lead to adverse effects such as anxiety, headaches, or digestive disturbances.
