Could a common supplement help tame multiple sclerosis?
NCT ID NCT07595081
First seen Jun 26, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This study tested whether a dietary supplement called propionic acid is safe and helpful for people with multiple sclerosis (MS). Twenty-two adults with stable MS took propionic acid capsules alongside their usual MS medications. Researchers measured nerve damage markers and thinking speed to see if the supplement made a difference.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- Active substance
- propionic acid (a dietary supplement)
- What this could lead to
- If it works, this could point toward a simple, safe supplement to help control multiple sclerosis and slow nerve damage.
- What could go wrong
- This was a small, early-stage study with only 22 people. The results may not apply to everyone with MS, and the supplement might not show clear benefits in larger trials.
