B-Complex vitamins to protect astronauts during long space missions
Part of Brain & nervous system, Eyes & vision clinical trials.
This early study tests whether a B-vitamin supplement (called B-Complex) can act as a helpful countermeasure during long stays on the International Space Station. It is only for astronauts assigned to specific 6–12 month missions.
Summary written for real people, not researchers, by Clin2.
Who can take part
- You must be an astronaut chosen for a 6–12 month mission on the International Space Station
- You must not currently be taking B-vitamin supplements
- You must be able to follow the study’s supplement instructions during the mission
