10. Guaranteed, Balanced Dosage – As mentioned, whey protein naturally contains BCAAs. So, why take a separate supplement. Even a high quality protein, like Momentus Strength Recover, will only contain a set amount of BCAAs – which will also be mixed with all of the other aminos. And amino acids compete for absorption with each other. To get the full benefit of BCAAs, then, a dedicated amino acid supplement, such as Klean BCAA, is needed
9. Improved Muscle Growth – Okay, but what’s the point? What do BCAAs actually do? Lots of stuff, as it turns out. The primary reason that people turn to amino acid supplements, though, has to do with muscle growth. Leucine, in particular, has been shown to regulate and improve muscle protein synthesis after exercise. Stimulated by the stress of your workout and encouraged by the jolt of leucine, then, your muscles will have everything they need to grow and be better prepared for your next workout.
8. Increased Endurance – We’ll talk about this a little more in the next point, but amino acid supplements change the way your body uses your primary fuel sources – carbs and fat. For many athletes, especially those who depend on short bursts of power like sprints, glycogen depletion is a major problem, leading to exhaustion and a sharp drop in performance. Interestingly, a 2011 study put 7 male volunteers through a workout that was designed to totally destroy their glycogen supply. One group was given BCAAs and the other was given a placebo. The glycogen stores in the BCAA group were protected so well that these subjects saw a 17.2 percent increase in the time it took for them to hit the wall.
7. Greater Fat Burn – So, how do you think BCAAs protected the glycogen of those athletes? By burning fat instead. For those trying to lose some body fat, or athletes training on a low-carb diet, then, BCAAs will help your body make the switch to depending on fat for fuel.
6. Reduced Fatigue – Related to the above-mentioned findings, BCAAs have demonstrated the ability to ward off the mental fatigue that sometimes accompanies long workouts. Primarily, this is because the relationship between low BCAAs and tryptophan. Normally, when your BCAA levels drop, your body produces more tryptophan which then becomes serotonin in your brain and leads to feelings of tiredness and mental fatigue. BCAA supplements prevent this process.
