A metabolite reflecting muscle protein turnover.
3-Methylhistidine is a modified amino acid released when muscle proteins are broken down. Because it is not reused to build new protein, it is passed out in urine. Its level reflects both muscle turnover and recent intake of meat, which also contains it.
It is measured as part of a plasma amino acid profile. Levels can reflect muscle protein breakdown and recent meat intake. It is read for context within the wider panel rather than as a stand alone test of any single condition.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.

Amino acid ranges vary by laboratory and method. They are best read as part of the full plasma amino acid profile, not in isolation.
Recent meat intake, total protein intake, fasting state, and time of day affect the result. A fasting morning sample gives the most reliable reading.
