Nutrition before workout is extremely important for muscle growth. Multi-ingredient pre-workout foods are formulations designed to stimulate the body into performing at a higher level of training. The best pre-workout supplement as well as work out supplements are formulations that achieve their goals through Nitrous Oxide (NO) compounds – which increase the pump effect of muscles in training through enhanced blood flow, Branched Chain Amino Acids (BCAA’s) – which provide muscles with key pre-workout nutrition amino acids necessary for repair, growth and recovery, Lactic Acid Buffers – which accelerate muscle recovery and finally, Anti-Catabolic agents like glutamine and leucine – which help muscles recover faster.
