D-Phenylalanine, USP

According to my research I've come to the conclusion that D-Phenylalanine is a safe alternative to aspirin, tylenol, ibuprofen and opiates for acute and/or chronic pain. D-Phenylalanine is non-addictive and will not upset the stomach. By Bonnie O'Sullivan, Editor, The Road To Health Newsletter

Safety Issues

Both L- and D-phenylalanine must be avoided by those with the rare metabolic disease phenylketonuria (PKU).

The maximum safe dosages of phenylalanine have not been established for young children, pregnant or nursing women, or those with severe liver or kidney disease.

Interactions You Should Know About

There are some indications that the combined use of DL- or L-Phenylalanine with antipsychotic drugs might increase the risk of developing the long-term side effect known as tardive dyskinesia, or worsen symptoms in those who already have it.

Like other amino acids, DL- and L-Phenylalanine may interfere with the absorption or action of the drug levodopa, which is used for Parkinson's disease.

It is recommended that D-Phenylalanine be taken with vitamins and minerals.


Always ask for pure pharmaceutical grade D-Phenylalanine or "USP," which will give you the highest amount of endorphin production.
