Beta-Alanine vs. L-Taurine: Study Establishes Inverse Relationship
Image 1: Beta alanine It is not new that there exists an antagonistic relationship between muscle carnosine (M-Carn, which is increased via beta-alanine supplementation), on the one hand, and muscle taurine (M-Tau) levels on the other. The study by Harris, et.al. (Harris. 2010) is however the first to report on the immediate effect of supplementing with 2x800mg of a time-released beta-alanine (structure, cf. image 1 on the right. HMDB v2.5 ) formula on muscle taurine content in seven male subjects after four weeks of daily supplementation. A realistic scenario as these dosages can be found both in stand-alone, as well as an kitchen-sink approach supplements such as NO-Xplode & Co : Pre and post supplementation M-Carn was 25.9 ± 4.3 and 41.3 ± 5.5 mmol.kg -1 dry muscle and M-Tau 28.1 ± 7.1 and 22.6 ± 7.0 mmol.kg -1 dry muscle . Despite the 20% fall in M-Tau , values of M-Tau remained within the normal physiological range . Before supplementation M-Tau was negative...
