New PKU food shows promise in small trial
NCT ID NCT05487378
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This completed trial tested whether PKU GOLIKE, a special food for managing PKU, works better than standard amino acid protein substitutes at controlling blood phenylalanine levels. Sixteen children with PKU, aged 5 to 16, took part in a crossover study where they tried both products for 7 days each. Researchers measured blood phenylalanine and tyrosine levels, sleep quality, and diet to see if PKU GOLIKE offers smoother control.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- PKU GOLIKE (a food for special medicinal purposes for dietary management of PKU)
- What this could lead to
- If it works, this could show that PKU GOLIKE helps control blood phenylalanine levels more smoothly than standard protein substitutes.
- What could go wrong
- This is a small, early-stage trial with only 16 children, so results may not apply to everyone. It's a dietary supplement study, not a treatment, so it won't cure PKU.
