Dorian Yates’ Renew BCAA’s contain a generous 6g of BCAA’s per serving in addition to 2000mg citrulline malate, 1000mg beta-alanine, 1000mg taurine, and 5µg vitamin D, to contribute to the maintenance of normal muscle function and immunity, making it the perfect intra-workout partner for anyone engaged in vigorous exercise. Dorian Yates’ BCAA’s do not leave the performance enhancing benefits there either, we are aware of the BCAA’s benefit to not just direct lean mass accretion, but also to overall performance, hence the inclusion of Beta-alanine, Citrulline malate, Taurine and even, the mighty and important Vitamin D. It all boils down to synergy, how one ingredient works with another to provide cumulative benefit. With an optimally dosed 6g of BCAA’s per serving at a ratio of 10:1:1 (Leucine, Isoleucine and Valine respectively), plus 2000mg citrulline malate, 1000mg beta alanine, 1000mg taurine, and 5μg vitamin D, we deliver an intra-workout supplement that caters to the maintenance of normal muscle function and muscle mass, muscle endurance, optimal performance, recovery and immunity. When leucine is taken in isolation, total lean mass accretion is less than if it were combined with Isoleucine and Valine. It is for this reason that Dorian Yates’ BCAA’s provide an optimal 10:1:1 ratio of Leucine, Isoleucine and Valine. You will also see BCAA’s with a 2:1:1 and even 8:1:1 ratio, however we know Leucine to be critical to lean mass accretion, hence the high ratio of Leucine.
