The simplest amino acid, important for collagen and detoxification.
Glycine is the smallest amino acid. The body can make it, and it has many roles. It helps build proteins and collagen, takes part in making the antioxidant glutathione, and acts as a signalling molecule in the nervous system.
It is measured as part of a plasma amino acid profile. Levels reflect protein metabolism and several pathways that depend on glycine. A clearly raised level can point to inherited disorders of glycine handling and is interpreted alongside the rest of the 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.
| Group | Adult fasting plasma range |

| Adults | 140 to 420 µmol/L |
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 protein intake, glycine supplements, fasting state, and time of day affect the result. A fasting morning sample gives the most reliable reading.
