Taking Sustamine® L-alanyl-L-glutamine after endurance exercise increases athletes’ reaction times and cognitive function when compared to no hydration, according to a study published in the European Journal of Sport Science.
Twelve male athletes performed four endurance trials of various lengths. One trial allowed no hydration, with another consisting of consumption of an energy drink. The other two trials included low and high doses of Sustamine in energy drinks.
Participants were then given a reaction time test where they had to press buttons as quickly as possible when lit up with either a hand or foot. With no hydration, researchers found athletes’ reaction time was actually negatively affected while those taking Sustamine saw a noticeably higher number of correct hits.
For cognitive tests, participants were required to subtract the number 7 from a random four-digit number. The number of correct answers was recorded. Non-hydrated subjects had correct answers as high as 5.02; those who ingested Sustamine had correct answers as high as 5.96 to 7.3. To view the entire study, click here.
Sustamine is a dipeptide of glutamine that provides several substantial benefits such as enhanced recovery, immune system support, and increased metabolic rate. On top of these benefits, research suggests that Sustamine is absorbed more than 240 percent better than standard L-glutamine. This means you get results while having to use less.
