I’m no expert on the biology, but my intuition would in any case have been that the effect size would be tiny/negligible for 6 weeks of supplementation, and that for non-trivial effects, you would need sustained supplementation over a longer time period.
Is there any reason to doubt my intuition on this?
I believe prior work showed large effects from short periods of supplementation. (Edit: Note that this work seems to debunk prior work, but this should explain the study design)
We also see moderate to large effects from short periods of supplementation for the non-cognitive effects, so we might expect similar saturation for the cognitive effects.
Great that you did this, really appreciate it.
