Focus & Cognition Protocol.

Enhance acetylcholine signaling, neuroplasticity, and prefrontal cortex function for sustained mental clarity.

In short

The focus & cognition protocol in brief.

A quick summary. The full stack, with dose and timing for each supplement, is below.

The Focus & Cognition Protocol is an intermediate stack of 5 supplements aimed at focus: Lion's Mane, Citicoline, L-Tyrosine, Creatine, and Alpha-GPC. 3 are core and the rest are optional add-ons, at roughly $40-65/mo. Each supplement below lists its dose, timing, role, and the evidence behind it.

Lion's Mane

Stimulates nerve growth factor (NGF) synthesis to support neuroplasticity and long-term cognitive health

Citicoline

Provides choline and cytidine for acetylcholine and phospholipid synthesis; improves focus and attention

L-Tyrosine

Precursor to dopamine and norepinephrine; particularly effective under stress or sleep deprivation

Creatine

Brain tissue demands high ATP; creatine supplementation supports cognitive processing and working memory

Alpha-GPC

Most bioavailable choline source; rapidly crosses blood-brain barrier to boost acetylcholine for memory and attention

Why it works together

How the pieces combine.

The mechanistic rationale for stacking these together rather than taking them in isolation.

  • Citicoline + Alpha-GPC provide dual-pathway choline loading for robust acetylcholine synthesis
  • Lion's Mane promotes neuroplasticity while cholinergics enhance real-time neurotransmission
  • L-Tyrosine supports dopamine under stress, complementing cholinergic focus pathways
