The Claim

Intravenous lysine infusion in healthy children is associated with elevated plasma ornithine and urinary putrescine levels, suggesting impaired mitochondrial ornithine transport.

How it works
1 study reviewed
In plain English

When healthy children receive lysine through an IV, their blood ornithine and urine putrescine levels rise, indicating a reduction in the ability of mitochondria to transport ornithine.

See the scientific wording

Intravenous lysine infusion in healthy children is associated with elevated plasma ornithine and urinary putrescine, suggesting impaired mitochondrial ornithine transport.

Why this might work

When lysine enters liver cells, it blocks the transport of ornithine into the energy-producing parts of the cell, so ornithine builds up in the blood. The excess ornithine gets converted into putrescine in other parts of the cell and is dumped into urine. At the same time, lysine also stops a key enzyme from using ornithine to make urea, which causes more ornithine to pile up and triggers the production of abnormal waste products.

  1. Study: Inhibitory effect of intravenous lysine infusion on urea cycle metabolism

    When kids got a special IV drip of lysine, their blood had more ornithine and their pee had more putrescine, which means their cells couldn’t move ornithine into the energy factories (mitochondria) properly. The study saw exactly what the claim says.
