The Esports Athlete's Supplement Stack

Esports is a legitimate performance domain. Six-plus hour sessions of high-decision-density gameplay demand sustained focus, sub-200 ms reaction speed, glucose stability, and eye recovery. The stack below is what the science supports — no gamer-branded blends.

Focus & Reaction Time

• L-theanine 200 mg + caffeine 100 mg — the most validated cognitive stack in the literature. Sharpens focus without the jitter.
• Alpha-GPC 300–600 mg — increases acetylcholine, shortening reaction time and improving working memory in RCTs.
• Creatine 5 g/day — improves cognitive resilience under sleep deprivation and long mental effort; a decade of data supports its use as a nootropic in addition to a strength aid.

Sustained Session Endurance

• Electrolytes (1,000 mg sodium, 300 mg potassium, 100 mg magnesium in 750 mL water) — most gamers are chronically low-sodium, which crushes late-session performance.
• Slow-digesting carbs (oats, sweet potato, rice) 60–90 min pre-match rather than sugar, to avoid the mid-tournament crash.
• Tyrosine 500–1,000 mg for extended sessions — supports dopamine and reduces cognitive decline under stress.

Eye Recovery

• Lutein + zeaxanthin (10 mg / 2 mg) — reduces blue-light strain and improves contrast sensitivity in gamers.
• Omega-3 (2 g EPA+DHA/day) — supports tear film, reduces dry-eye complaints reported by pros.

Sleep Recovery (Because Late Tournaments Wreck Rhythm)

• Magnesium L-threonate before bed.
• 0.3 mg (not 5 mg) melatonin only for schedule shifts.
• Blue-light blockers 2 hr before sleep on tournament nights.

The Bottom Line

Treat esports like the endurance-of-attention sport it is. Caffeine and taurine alone are amateur hour — build the focus stack, protect your eyes, and defend your sleep.
