Who Should Avoid It
Individuals with high blood pressure, pregnant or breastfeeding women, and those on MAOI inhibitors should avoid DL-Phenylalanine without medical advice.

RESEARCH QUALITY ASSESSMENT:
- Studies were conducted in the late 1970s and 1980s; methodologies may not meet current standards.
- Sample sizes were relatively small, limiting generalizability.
- Short study durations; long-term effects remain unclear.
- Further large-scale, randomized controlled trials are needed to confirm findings and assess long-term safety and efficacy.
