Lactic acid is a biologically important acid and a by-product of anaerobic metabolism. The conjugate base of lactic acid is called lactate. Most of the time, the term "lactic acid" refers to L-lactic acid, the form of lactic acid produced in animals. Some bacteria produce a different form, called D-lactic acid. There is evidence that lactic acid in animals may be an important fuel for myocardial energy metabolism.[1]

In human disease[edit | edit source]

ME/CFS[edit | edit source]

Elevated blood lactate has been found in both resting ME/CFS patients[2] and following exertion. ME/CFS patients with higher elevated lactate at rest may have more severe post-exertional malaise after activity.[2]

ME/CFS - An acronym that combines myalgic encephalomyelitis with chronic fatigue syndrome. Sometimes they are combined because people have trouble distinguishing one from the other. Sometimes they are combined because people see them as synonyms of each other.

post-exertional malaise (PEM) - A notable exacerbation of symptoms brought on by small physical or cognitive exertions. PEM can last for days or weeks. Symptoms can include cognitive impairments, muscle pain (myalgia), trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, among others.
