An essential, sulphur-containing amino acid central to methylation.
Methionine is an essential sulphur-containing amino acid that comes from food. It is needed to start building most proteins and is the source of S-adenosylmethionine, a key methyl donor for many reactions. It also feeds into the pathway that makes cysteine and homocysteine.
Plasma methionine is part of a full amino acid profile. Low levels can reflect poor intake, while high levels can point toward liver issues or inherited disorders of sulphur amino acid metabolism. It is read alongside homocysteine and the other amino acids.
Aniva reads your result against research-backed ranges, not just the lab's wide normal. The reference shown below is specific to this biomarker.
Adult fasting plasma, guidance only:
| Analyte | Typical adult range (µmol/L) |
|---|---|
| Methionine | 13 to 35 |
Ranges vary by laboratory and assay and are read as part of the full amino acid profile.
Results are affected by recent diet, recent protein intake, fasting state and the time of day the sample is taken.
