How it works

Strong evidence supports its use for cognitive decline in dementia. In healthy adults, it is used as a nootropic for short-term memory and focus, though large-scale trials in this population are limited.

Acts as a reversible inhibitor of acetylcholinesterase, preventing the breakdown of acetylcholine and increasing its availability in the brain.

Safety

  • Requires cycling to prevent acetylcholine buildup.
  • May cause nausea or muscle twitches at higher doses.
