Berry boost: blackcurrant drink may fight altitude brain fog
NCT ID NCT07166835
First seen Jun 26, 2026 · Last updated Jun 26, 2026
Summary
This study tests a blackcurrant-based drink called Ārepa to see if it helps thinking and mood during simulated high altitude (4,500 meters). Twenty-seven healthy men will take the drink or a placebo in random order, then do thinking tasks and have their heart rate, oxygen levels, and blood markers checked. The goal is to find out if the drink can support brain function when oxygen is low.
What this could mean
Our plain-language read of the trial. This is informational only — not medical advice or a prediction.
Active substance
Blackcurrant-based nootropic drink with anthocyanins, L-theanine, and Enzogenol
What this could lead to
If it works, this could point toward a natural drink to help people think clearly in low-oxygen environments like high altitude or possibly other settings.
What could go wrong
This is a very small, early trial with only 27 healthy men, so results may not apply to others. The effect may be small or not noticeable in real-world conditions.
