[Lipoic acid: physiological role and prospects for clinical application]

Area of Science:

• Biochemistry
• Nutritional Science
• Pharmacology

Background:

• Alpha-lipoic acid (ALA) is a vitamin-like compound with antioxidant properties.
• ALA exists as R- and S-enantiomers, with R-ALA synthesized in the body.
• ALA acts as a cofactor in mitochondrial enzymes and influences cellular signaling.

Purpose of the Study:

• To review the multifaceted roles and therapeutic potential of alpha-lipoic acid.
• To explore ALA's antioxidant mechanisms and effects on cellular processes.
• To summarize evidence for ALA's efficacy in managing diabetic neuropathy, metabolic disorders, and obesity.

Main Methods:

• Literature review of existing studies on alpha-lipoic acid.
• Analysis of randomized controlled trials investigating ALA supplementation.
• Examination of ALA's biochemical functions and antioxidant activities.

Main Results:

• ALA and its derivative dihydrolipoic acid neutralize reactive oxygen species.
• ALA supplementation shows promise in reducing peripheral diabetic neuropathy symptoms.
• High-dose ALA may improve glycemic profiles in metabolic disorders and aid in weight management.

Conclusions:

• Alpha-lipoic acid possesses significant antioxidant and therapeutic potential.
• ALA supplementation may be beneficial for managing metabolic disorders and associated complications.
• Further research into optimal dosing and enantiomer-specific effects is warranted.
