DL-phenylalanine 1 g


For adults, begin with a small dose, adjusting as needed. Consult a healthcare professional for the recommended dosage.

  • Due to potentially impaired metabolism, caution supplementing in those taking MAOI medications.
  • It may compete with L-Dopa medications for transport across the blood-brain barrier (separate doses).
  • DL-Phenylalanine has not been extensively tested for its effects during pregnancy.
  • Health practitioners may prefer to avoid its use during pregnancy or lactation unless confident that its impact can be reasonably deemed to be safe or beneficial.
  • Always read the label.
  • Dietary supplements should not replace a balanced diet.
  • If symptoms persist, worsen or change unexpectedly, consult your healthcare professional.
