Cognitive Effects of Black Cardamom Extract and Caffeine Clinical Trial

A 96-participant clinical trial investigated the acute cognitive effects of a black cardamom extract, caffeine, and their combination. Jestin V. Thomas published the study results on figshare in 2026. The data includes cognitive performance assessments measured at multiple time points post-dose.

Use Cases

• Compare reaction time and error rates from the Shifting Attention Test between placebo, caffeine, and black cardamom extract groups.
• Analyze the number of correct responses and errors in the Symbol Digit Coding Test across four treatment arms over five measurement time points.
• Model the sustained cognitive benefit duration by examining performance changes at 1-, 3-, 5-, and 8-hour post-dose intervals.
• Assess the interaction effect of co-supplementation (MA2-24 + caffeine) on Stroop Test reaction time and error reduction compared to single treatments.

Strengths

• Data from a randomized, double-blind, placebo- and active-controlled study design with 96 participants.
• Cognitive performance was measured at five specific time points (baseline, 1, 3, 5, 8 hours) for granular temporal analysis.

Limitations

• The dataset is very small at 23.5 KB, likely containing summary results rather than raw individual participant data.
• Limited to a specific demographic of 96 healthy working-class adults aged 35-65, reducing generalizability.
