Phenylketonuria
An inborn error of metabolism where the body cannot break down the amino acid phenylalanine. Supplementing with phenylalanine (including DL-phenylalanine and collagen, which is rich in amino acids) is strictly contraindicated as it leads to phenylalanine buildup and toxic effects on the brain.

What may help (1)
- Elimination Diet Practices Very highTheoretical
For individuals with Phenylketonuria (PKU), a rigorous, lifelong elimination of dietary phenylalanine, an amino acid found in most protein-rich foods, is imperative. This specialized diet prevents the accumulation of toxic levels of phenylalanine in the brain, thereby averting severe intellectual disability and supporting optimal neurological development.
What to avoid (12)
- Adequate Protein Intake Habits Very highTheoretical
For individuals with Phenylketonuria (PKU), a genetic disorder, phenylalanine (an amino acid found in all proteins) cannot be properly metabolized. A strict low-phenylalanine diet, requiring highly restricted protein intake, is essential and must be medically supervised.
- Chlorella Supplements Very highTheoretical
As a significant source of protein, chlorella contains phenylalanine and is strictly contraindicated for individuals with phenylketonuria (PKU).
- Collagen Peptides Supplements Very highTheoretical
If you have Phenylketonuria (PKU), a rare genetic disorder, avoid collagen supplements as they contain phenylalanine, which your body cannot properly process and can be harmful.
- DL-Phenylalanine (DLPA) Supplements Very highTheoretical
If you have phenylketonuria (PKU), strictly avoid DLPA. Your body cannot properly process phenylalanine, and this supplement could lead to dangerous brain damage.
- EAA (Essential Amino Acids) Supplements Very highTheoretical
Absolutely avoid if you have Phenylketonuria (PKU), a genetic condition that prevents the proper metabolism of phenylalanine, an essential amino acid found in this product.
- Herbalism / Phytotherapy Practices Very highTheoretical
Individuals with phenylketonuria (PKU) must strictly avoid herbal products containing phenylalanine (e.g., certain protein-rich plant materials) as it can cause severe neurological damage. Consult a specialist.
- Naturopathy Practices Very highTheoretical
Supplements containing phenylalanine (including DL-phenylalanine or collagen-rich products) are strictly contraindicated due to toxic phenylalanine buildup.
- Phenylalanine Supplements Very highTheoretical
Strictly avoid if you have phenylketonuria (PKU), as your body cannot properly process phenylalanine, leading to harmful buildup that can cause severe neurological damage.
- Proline Supplements Very highTheoretical
If you have phenylketonuria (PKU), avoid L-Proline. Your body cannot properly process certain amino acids, and L-Proline, as an amino acid found in proteins like collagen, could contribute to an unsafe amino acid load, potentially worsening your condition.
- Protein Supplements Very highTheoretical
For individuals with phenylketonuria (PKU), all protein supplements are strictly contraindicated due to their inherent phenylalanine content, which can be toxic.
- Spirulina Supplements Very highTheoretical
Individuals with phenylketonuria (PKU) must strictly avoid spirulina due to its high phenylalanine content, which can be dangerous for their condition.
- Trypsin Supplements Very highTheoretical
If you have phenylketonuria (PKU), avoid oral trypsin as it breaks down proteins into phenylalanine, which is toxic in this condition.
