Looking for something to boost your recovery time, while promoting muscle growth at the same time? Then choose NutraBio’s BCAA 5000 which features a 2:1:1 ratio. This pharmaceutical grade BCAA supplement supports muscle growth and promotes recovery by providing an excellent source of amino acids. With the 2:1:1 ratio of leucine, isoleucine, and valine, your body will be able to recover faster and get to your next workout quicker. Leucine gets things going by activating a complex called mTOR, which essentially means it is ramping up the rate at which our bodies undergo protein synthesis, or muscle growth. At the same time, valine works to reduce serotonin levels which in turn decreases the likeliness that tryptophan will enter the brain, which allows the body to forgo or postpone the time it takes your muscles to fatigue.
