DL-Phenylalanin (also known as DLPA) is a synthetic combination of the D- and L-forms of the amino acid phenylalanine. It is used in the biosynthesis of proteins and as a dietary supplement for its purported analgesic and antidepressant effects.
Chemistry
DL-Phenylalanin is made up of equal parts D-Phenylalanine and L-Phenylalanine. The L-form is a precursor to the neurotransmitters dopamine, norepinephrine, and epinephrine, whereas the D-form may be involved in the modulation of pain signals and mood.
Pharmacology
DL-Phenylalanin's effects as a supplement are attributed to its ability to influence various neurotransmitter systems. It may also play a role in the production of other bioactive molecules, such as the skin pigment melanin.
Subjective effects
Subjective effects of DL-Phenylalanin can include mood enhancement, potential pain relief, and a mild boost in energy. These effects are generally subtle and may vary greatly between individuals.
Dosage and Duration
- Threshold: 50 - 100 mg - Light: 100 - 300 mg - Common: 300 - 500 mg - Strong: 500 - 700 mg - Heavy: 700 mg +
The duration of effects typically lasts: - Onset: 15 - 30 minutes - Peak: 1 - 2 hours - Offset: 2 - 3 hours - After effects: 1 - 2 hours
Toxicity and harm potential
DL-Phenylalanin is generally well-tolerated in dietary supplement doses. Individuals with phenylketonuria should avoid phenylalanine due to their inability to metabolize it effectively.
Legal status
DL-Phenylalanin is legal in most countries and is sold as a dietary supplement.
