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.

Evidence summaries

Paper IDs and full lists are private. Only study types and summaries are shown.

Key Evidence #1
Public scholarly dataCitation signal: 954
review

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 Evidence #2
Public scholarly dataCitation signal: 254
observational

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.

Key Evidence #3
Public scholarly dataCitation signal: 63
observational

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.

Public scholarly dataCitation signal: 52
observational

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.

Public scholarly dataCitation signal: 42
observational

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.

Public scholarly dataCitation signal: 41
observational

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.
