Caffeine 2
Performance Lab
Overview
Performance Lab Caffeine 2 offers a well-formulated stack of ingredients with strong evidence for their individual cognitive and energy-enhancing benefits. The combination of caffeine and L-Theanine at a 1:2 ratio is particularly effective for achieving a state of 'calm alertness'. L-Tyrosine further supports cognitive function during stress. The proprietary B-Complex, while individually efficacious, lacks specific dosage transparency, which slightly limits a full assessment of its contribution.
The Good
Mitigates Caffeine Jitters and Crashes: The 1:2 ratio of caffeine to L-Theanine is scientifically supported to provide a smooth, focused energy boost without common stimulant side effects.
Enhanced Focus and Cognitive Performance: The combination of caffeine, L-Theanine, and L-Tyrosine synergistically supports alertness, concentration, and mental performance under demanding conditions.
Sustained Energy Production: B-vitamins in the complex contribute to cellular energy metabolism, helping to maintain energy levels and potentially counteract caffeine-induced B-vitamin depletion.
The Bad
Proprietary Blend for B-Complex: The exact doses of B-vitamins in the 'NutriGenesis® Caffeine Balance B-Complex' are not disclosed, making it difficult to assess their optimal contribution.
Potential for Individual Caffeine Sensitivity: Despite the L-Theanine, highly caffeine-sensitive individuals may still experience mild side effects.
Not Suitable for Evening Use: Due to its stimulant content, taking this supplement in the late afternoon or evening may disrupt sleep.
Is it for you?
