Summary

This study looked at 30 undernourished teens with anorexia, aged 11 to 17, to see how taking oral phosphorus supplements for 6 months changes a hormone called FGF23, which helps control phosphate and vitamin D levels. The goal was to understand the link between phosphorus intake and FGF23, not to treat anorexia. Results could guide future research on bone health in malnourished teens.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance: oral phosphorus supplements (Phosphoneuros®)
What this could lead to: If successful, this could help doctors understand how phosphorus affects bone-related hormones in undernourished teens with anorexia.
What could go wrong: This is a small, completed study with only 30 participants, so results may not apply broadly. It is exploratory and does not test a treatment for anorexia itself.
