An indispensable constituent of your exercise supplement armamentarium. Surprisingly, l-citrulline lowered plasma insulin and nitrite concentrations and impaired exercise performance compared with placebo. Because of the reduced fpm of citrulline and the fact that the only known fate of this amino acid is it’s conversion to arginine, citrulline has the potential not only to circumvent the adverse side effects of arginine supplementation, but also to be a more efficient option to increase arginine availability. However, the evidence in healthy individuals is not conclusive, since other researchers found no benefit of citrulline over periods of one to four weeks (14, 18).
On day 10 of the supplementation period, subjects will complete a performance test on a cycle ergometer to investigate their endurance performance. The three amino acids function together to get rid of the ammonia, a toxic byproduct of protein metabolism, from body. However, when highly trained subjects were supplemented, no positive effect on performance was indicated. To date, only one study has investigated the effect of acute mips supplementation on time to exhaustion during endurance exercise, with promising results. Upon ingestion, l-citrulline is likely transformed to l-arginine, an amino acid that raises nitric oxide levels to enhance blood flow.
