Astaxanthin has not been tested in clinical trials for ALS
Original source
Astaxanthin (opens in a new tab)Astaxanthin has theoretical mechanisms that could be relevant to amyotrophic lateral sclerosis (ALS), but it has not been tested in ALS-specific preclinical studies or clinical trials in people with ALS. A reported ALS reversal occurred while one person was taking astaxanthin alongside several other therapies, so the association does not show that astaxanthin caused the improvement.
Why this matters
People with ALS do not have clinical evidence that astaxanthin treats the disease. Further studies in ALS models and clinical trials would be needed to assess whether it is effective.
Limitations and context
This assessment is an independent expert review, not a clinical trial. The evidence described is limited to theoretical mechanisms and one reported case involving multiple therapies; astaxanthin’s effectiveness in ALS remains unknown.
