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]

post-exertional malaise (PEM) - A notable exacerbation of symptoms brought on by small physical or cognitive exertions. PEM may be referred to as a "crash" or "collapse" and can last for days or weeks. Symptoms can include cognitive impairments, muscle pain, trouble remaining upright (orthostatic intolerance), sleep abnormalities, and gastro-intestinal impairments, and others.
