Under the Hood

Targets alertness, attention, and mental stamina without aggressive stimulant dosing.

Improves daytime alertness
May reduce caffeine jitters
Supports mental fatigue resistance
May help if fish intake or creatine intake is low

Expected Results

Caffeine/theanine effects are same-day; creatine and omega-3 are better assessed after 4-8 weeks.

Sharper morning focus
Less distracted work blocks
Better tolerance of caffeine
Little benefit if sleep debt is the main issue

Biological Synergies

Caffeine + L-Theanine

Caffeine improves alertness while theanine can reduce caffeine-related tension and improve attentional control.

Cleaner focus with fewer jitters than caffeine alone.

Creatine + Omega-3

Creatine supports brain energy buffering, while omega-3s support neuronal membrane composition.

A slow-burn foundation for cognitive resilience rather than an acute stimulant effect.
