Lactate, also called lactic acid, is a byproduct of anaerobic metabolism — the process of breaking down glucose for energy without sufficient oxygen, often during intense exercise. It is linked to muscle fatigue and the familiar “burn” sensation in strenuous activity. Lactate also participates in the Cori cycle, where it is converted back into glucose in the liver.
Testing lactate levels can be beneficial for several groups:
Dysregulated lactate levels, particularly elevated lactate, can lead to a condition known as lactic acidosis, which presents with various symptoms:
Regulating lactate levels involves addressing the underlying factors that lead to its accumulation:
