Though LA has long been touted as an antioxidant, it has also been shown to improve glucose and ascorbate handling, increase eNOS activity, activate Phase II detoxification via the transcription factor Nrf2, and lower expression of MMP-9 and VCAM-1 through rep

Key cautions to review
Standalone side-effect signals and combination cautions are listed separately.
Side-effect and combination signals
No standalone side-effect or combination signal is currently clear enough to show from the collected papers. This does not mean there is no concern.

The combination of ω-3 + LA slowed cognitive and functional decline in AD over 12 months and further evaluation of the combination of omega-3 fatty acids plus alpha-lipoic acid as a potential treatment is warranted.
Alpha-lipoic acid and spinal cord stimulation were effective for pain; studies were short-term with quality deficits and further research should address long-term outcomes and other non-pharmacologic treatments.

Four biopsy-proven cases of neural epidermal growth factor-like 1 (NELL1)-associated membranous nephropathy following lipoic acid supplementation and a fifth suspected case are described.
It is speculated that alpha-lipoic acid might have an antioxidant effect in pediatric diabetes patients by reducing insulin, unlike diet with placebo or controls.
LA supplementation decreased lipid peroxidation and oxidative damage of proteins and improved non-enzymatic antioxidant capacity in healthy controls and no significant changes were observed on oxidative damage in patients with schizophrenia.
