Creatine And Beta Alanine Formula Shows Promise

is well established as a performance enhancer, whereas beta-alanine has just recently been examined in scientific studies. Nevertheless, the preliminary studies of beta-alanine have shown that it also improves exercise performance through completely different mechanisms. In one of the first studies to assess the combined effects of creatine monohydrate and
, researchers note some interesting findings. In this study, healthy men were randomized into one of four supplementation groups: placebo, creatine monohydrate only, beta-alanine only, and
. Before and after 4 weeks of supplementation they all performed an exercise test that progressively increased in intensity while measures were made of their metabolic responses. The combined creatine and beta-alanine condition was the only group to demonstrate an increase in lactate threshold. This means that subjects in this group could exercise longer and at a higher intensity without accumulating toxic substances that can lead to fatigue. The findings provide preliminary evidence that creatine and beta-alanine may work together to produce favorable metabolic adaptations within skeletal muscle that translate into more efficient performance.
