ALS Untangled does not support spirulina use for ALS
An ALS Untangled expert review found no evidence that spirulina is effective for amyotrophic lateral sclerosis (ALS). It also identified possible real and theoretical toxicities and said it does not support spirulina use until better efficacy and safety studies are published.
Why this matters
This concerns people with ALS who may be considering spirulina as a treatment. The review does not show that spirulina provides a benefit, and it raises safety concerns, so it does not support using it for ALS.
Limitations and context
This is an independent expert review published in 2011, not a new clinical trial. The source does not provide study results or quantify spirulina’s potential benefits or risks. Further efficacy and safety studies would be needed.
