The Claim
In French adults with early-treated phenylketonuria, individuals with low bone mineral density have a significantly lower body mass index (median 20.4 kg/m²) and a higher intake of amino acid supplements (0.80 g/kg/day) compared to individuals with normal bone mineral density (median 24.4 kg/m² and 0.53 g/kg/day, respectively).
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
Among French adults with early-treated phenylketonuria, those with low bone mineral density have a lower body mass index and consume more amino acid supplements daily than those with normal bone mineral density.

In French adults with early-treated phenylketonuria, those with low bone mineral density have a significantly lower body mass index (median 20.4 vs. 24.4 kg/m²) and higher intake of amino acid supplements (0.80 vs. 0.53 g/kg/day) compared to those with normal bone density.
People who eat a lot of special protein supplements and have low body weight produce excess acid in their blood, which forces their bones to release minerals to balance the acid. This weakens their bones over time.
What the research says
1 studyStudy: Bone mineral density in French adults with early-treated phenylketonuria.
In adults with PKU who have weak bones, the study found they tend to be thinner and take more special protein supplements than those with normal bone strength — exactly what the claim says.
