Which protein supplement is recommended for patients with PKU?

In the context of Phenylketonuria (PKU), tyrosine is particularly important as a protein supplement for patients. PKU is a genetic disorder that results in the inability to metabolize phenylalanine, an amino acid found in many proteins. Because individuals with PKU must avoid phenylalanine to prevent toxic buildup, they cannot consume regular protein sources safely.

Tyrosine, on the other hand, is a non-essential amino acid that can be synthesized from phenylalanine. However, individuals with PKU have limited ability to produce it due to their metabolic condition. Therefore, supplementing with tyrosine helps to ensure that patients receive the necessary amino acids to maintain optimal health and support bodily functions. This supplementation can help alleviate some of the potential deficiencies that might arise due to the dietary restrictions required for effectively managing PKU.

The other options, including phenylalanine, lysine, and tryptophan, are not suitable for patients with PKU. Phenylalanine must be avoided entirely due to its toxic effects in PKU. Lysine and tryptophan are also amino acids that do not address the specific needs of PKU patients and do not contribute to the management of the condition in
