ALS Untangled does not recommend using RCH4
Original source
RCH4 (opens in a new tab)ALS Untangled reviewed RCH4, an unlicensed and unapproved product promoted online as probably slowing ALS progression. It found only one peer-reviewed abstract, which was never presented at a meeting, and could not independently verify the product’s structure, safety or effectiveness. The review does not recommend using RCH4.
Why this matters
People with ALS and their clinicians do not have independently verified evidence that RCH4 is safe or effective. The review supports caution about using a product without regulatory oversight, independent peer review and replication.
Limitations and context
This is an expert review from ALS Untangled, not a new clinical study. The available evidence was limited to a single peer-reviewed abstract that was never presented at a meeting. ALS Untangled said it could not determine RCH4’s chemical class or independently verify its safety or effectiveness.
