Resveratrol is a dietary supplement that likely activates SIRT1 cellular pathways and may alter the gut microbiome. These are interesting mechanisms that may potentially alter the progression of ALS and do confer benefit in animal models of one type of familial ALS; however, to-date, there have been no trials of resveratrol in PALS. Some trials in other populations show frequent gastrointestinal adverse events, including weight loss, and one trial showed a high risk of serious renal toxicity. Given the unknown benefit of resveratrol in PALS and the possible risks, we cannot recommend resveratrol as an ALS treatment at this time. We hope to see well-designed clinical trials of resveratrol and other SIRT1 modulators in the near future.
