L-Taurine is a "transporter" amino acid which boosts performance. L-Taurine assists the transport of electrolytes into the muscle cell, which must occur for hydration to take place. It may also assist muscular uptake of amino acids and creatine, making it a particularly valuable performance booster. L-Taurine is most commonly used by athletes as an addition to pre / intra / post workout drinks to assist the transport of minerals, thereby improving hydration - this in turn increases protein synthesis, prevents catabolism, and increases energy and endurance.Recommendations: For energy and focus, take 1 serve before your workout with water. For rehydration and recovery, take after your workout as well in your protein shake.
