acetyl-L-carnitine hydrochloride

A nutritional supplement composed of the hydrochloride salt form of the acetylated form of the endogenously produced L-carnitine, with potential neuroprotective, cognitive-enhancing, anti-depressive and immunomodulating activities. L-carnitine is responsible for the transport of fatty acids into the mitochondria for breakdown. It may also relieve peripheral neuropathy induced by chemotherapy, diabetes or other diseases. In addition, acetyl-L-carnitine may modulate the immune response by increasing T lymphocytes maturation and may downregulate pro-inflammatory cytokines in response to viruses, such as SARS-CoV-2. It may also disrupt the ACE2 signaling pathway and inhibit the production of reactive oxygen species (ROS).
