The short answer: Yes, nootropics are very effective.
People taking nootropics literally responded faster and made quicker decisions in a significant, straightforward study at the University of Leeds.
The group taking a nootropic supplement showed significant improvements in simple reaction time, choice reaction time, and anticipation. The control group (placebo) showed no improvement on any measure.
One of the most sophisticated studies to date was published in Brain Sciences in 2025. Researchers monitored participants' brain activity as they took a multi-ingredient nootropic supplement daily for 60 days.
And they found something significant: widespread increases in brain network connectivity, cohesion, and energetic efficiency, particularly in the delta frequency band.
Their conclusion?
Natural nootropics can improve overall brain network function and efficiency. The brain is measurably working better. The effects may show up in more complex, real-world cognitive tasks rather than simple lab measures.
