Which self-optimization products do you recommend for more energy and focus?
Three products are proven for acutely boostable energy and focus: caffeine 100-200 mg (effect in 30-45 min, half-life 5 h), caffeine + L-theanine 200 mg (smoother alertness, less jitter), creatine monohydrate 3-5 g/day (cognition under sleep deprivation, effect after 2-4 weeks). Pre-workout blends and 'nootropic stacks' without transparent dosing are usually expensive marketing packages with stimulants.
