L-Phenylalanine 500 mg
Vitamin World's L-Phenylalanine 500 mg is an Amino acid/Protein supplement, categorized under Protein, providing 500mg of L-Phenylalanine per caplet. This product achieved an N+ Score of 46, earning an 'F' grade, which places it in the below-average tier. As a single-ingredient product, its label is fully transparent regarding the content. However, the analysis indicates that the 500mg dosage of L-Phenylalanine is not considered a clinically studied dose for common applications, which typically require higher amounts for potential cognitive or mood support. This underdosing is a significant weakness, suggesting that the product may not deliver substantial benefits despite its clear ingredient listing. Consumers seeking effective L-Phenylalanine supplementation with research-backed dosages may need to consider products with higher concentrations.
