A metabolite linked to dietary protein and muscle turnover.
1-Methylhistidine is a modified amino acid. It comes mainly from anserine, a compound found in the muscle of animals such as poultry and fish. When you eat these foods, anserine is broken down and 1-methylhistidine is released into the blood and passed out in urine.
It is measured as part of a plasma amino acid profile, usually as a marker of recent meat or fish intake rather than of a disease. A high level most often reflects diet. It can occasionally help explain an unusual pattern on the wider amino acid panel.
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 intake of meat or fish, overall protein intake, fasting state, and time of day all affect the result. A fasting morning sample gives the most reliable reading.
