Ginseng focus trial halted early – little to go on
NCT ID NCT07255755
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study tested whether a single 200 mg dose of American Ginseng (Cereboost) could improve attention and brain function in healthy young adults aged 18-40. Participants completed cognitive tests and gave blood samples over 6 hours. However, the trial was terminated early and only enrolled 27 people, so no reliable conclusions can be drawn.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
American Ginseng extract (Cereboost)
What this could lead to
If it worked, this could suggest a natural supplement for short-term attention or focus in healthy people.
What could go wrong
The trial was terminated early with only 27 participants, so results are incomplete and unreliable. Any benefits would be small and temporary, not a treatment for any condition.
