Risks (harms that occurred on this treatment)

Astaxanthin

January 25, 2023 by Alex Rodriguez

There are theoretical mechanisms supporting the potential role of astaxanthin in the treatment of ALS, however, there are no ALS-specific pre-clinical data exploring this treatment. One verified“ALS reversal” occurred while taking astaxanthin in the setting of a cocktail of various other therapies—an association that does not prove causality. There have been no clinical trials of astaxanthin in PALS. Natural astaxanthin appears to be generally safe and inexpensive. We believe there is a need for further pre-clinical and/or clinical trials of natural astaxanthin in disease models and PALS, respectively, to further elucidate efficacy.

Vitamin C

July 14, 2021 by Dr. Richard Bedlack

Vitamin C is safe and inexpensive. As an antioxidant, it has a plausible mechanism for influencing the course of neurodegenerative diseases. Two flawed preclinical studies by the same group showed benefits in a mouse model of familial ALS. There are two case reports in which it was associated with improvement. However, there are multiple possible explanations for the improvement in these cases. It is not clear which if any dose of vitamin C might be beneficial for PALS; a small clinical trial using oral vitamin C at 2,000 mg daily was unable to demonstrate benefits in PALS. Based on this negative trial, we currently advise against using vitamin C to treat ALS.

Melatonin

June 2, 2021 by Dr. Richard Bedlack

Melatonin has plausible mechanisms, some positive (and some negative) pre-clinical data, and two case reports in which it was part of a cocktail of treatments associated with recovery of lost motor function. As we have stated previously, there are
multiple possible explanations for cases like these. There was also a very small, flawed retrospective study suggesting that PALS taking it progressed more slowly and lived longer than PALS were not taking it. Melatonin appears safe at high doses, but evidence is lacking for a proven benefit in slowing disease progression in ALS. Furthermore, an optimal dose and route of administration have not been established. Based on this data, a pilot trial of melatonin in PALS would be reasonable, but we cannot yet recommend it as an ALS treatment.

Proprionyl-L-Carnitine

July 30, 2020 by Dr. Richard Bedlack

There are good theoretical mechanisms for carnitines, some pre-clinical evidence for LC and ALCAR, and a single clinical trial that suggested ALCAR could slow disease progression in PALS. All three carnitines appear to be well-tolerated, generally safe and inexpensive. We believe that there is a need for future clinical trials of carnitines in PALS to further elucidate their efficacy. Until there is further data, we cannot endorse any of these supplements as a definite way to slow ALS progression; however, oral ALCAR at 1000mg three times daily (3000 mg total daily dose) appears to be a theoretically promising supplement available for PALS whom would like to self-experiment.

Acetyl-L-Carnitine

Glutathione

November 29, 2019 by Dr. Richard Bedlack

As an ALS treatment, glutathione and cysteine-containing supplements that increase glutathione appear reasonably safe, and they have a plausible mechanism, positive preclinical data and 2 interesting case reports. Unfortunately small clinical trials of glutathione itself and of acetylcysteine showed no significant benefit. Given these negative clinical trials, we do not advise PALS to take glutathione or cysteine-containing supplements for their ALS at this time.

Acuscope

March 6, 2017 by Dr. Richard Bedlack

Acuscope appears reasonably safe, but it is not clear that it has a mechanism of action that would be useful to PALS. One person with PLS experienced slightly slower ALSFRS-R measurements while using Acuscope than she did before starting it, but a PALS had slightly faster ALSFRS-R progression during treatment. Since the natural history of motor neuron disease progression can vary spontaneously, it is not clear that either of these slight changes in progression were related to the treatment. Given these limitations, at this time we cannot endorse the use of Acuscope to slow, stop or reverse ALS progression.‌‌
