A dipeptide that buffers acid and supports muscle and brain health.
Carnosine is a small molecule made of two amino acids, beta-alanine and histidine. It is concentrated in muscle and brain tissue, where it helps buffer acid and acts as an antioxidant. In blood it is usually present only at very low levels.
It is measured as part of a plasma amino acid profile. Because an enzyme in blood breaks carnosine down quickly, plasma levels are normally low or hard to detect. 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.

Plasma carnosine is normally low or undetectable. Amino acid ranges vary by laboratory and method, and are best read as part of the full plasma amino acid profile.
Recent intake of meat, carnosine or beta-alanine supplements, fasting state, time of day, and rapid breakdown in blood all affect the result. A fasting morning sample gives the most reliable reading.
