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

  • 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.

  • If symptoms persist, worsen or change unexpectedly, consult your healthcare professional.
