<\/p>\nFor years, athletes have supplemented their diets with\u00a0branched-chain amino acids (BCAAs) because they believed BCAAs gave them a leg up on muscle recovery and muscle growth. But recent findings have shifted the scientific community\u2019s understanding of how amino acids work together, suggesting that essential amino acids (EAAs)\u00a0may be a more effective option.<\/p>\n
The conflicting information has led to more questions than answers. For example, what\u2019s the difference between EAAs vs BCAAs? Are EAAs better than BCAAs? Do EAAs build muscle?<\/p>\n
To get to the bottom of the quandary between EAAs and BCAAs, we spoke with Paul Falcone, principal scientist at OzHelp. Here\u2019s what he (and the research) had to say.<\/p>\n
EAAs and BCAAs are shorthand for types of amino acids, which are the molecules from which protein is made. Protein is the macronutrient that\u2019s largely responsible for building and repairing the body\u2019s tissues, a process also known as protein synthesis.<\/p>\n
When we consume protein, the digestive system breaks it down into amino acids, which are released into the bloodstream and processed by the liver before being used by the body.<\/p>\n
Of the 20 amino acids utilized by the body, nine are considered \u201cessential,\u201d which means they must be consumed in food. (The body can manufacture the other 11 non-essential amino acids on its own.) And of these nine essential amino acids, three are known as branched-chain amino acids, or BCAAs: leucine, isoleucine, and valine.<\/p>\n
Falcone explains that BCAAs share a similar, unique chemical structure, which is why they\u2019re grouped together. It\u2019s also why they were once believed to play similar roles in protein synthesis \u2014 an assumption that\u2019s now in question.<\/p>\n
\u201cIt became evident in the\u00a0scientific literature\u00a0that certain amino acids were driving the signaling of muscle protein synthesis,\u201d Falcone explains. In other words, all the amino acids play a role in building and repairing muscle tissue, but certain ones appear to initiate and direct the process.<\/p>\n
\u201cAt first, it seemed that those (signaling amino acids) were branched-chain amino acids,\u201d says Falcone. \u201cBut then it became clear that it was really\u00a0leucine\u00a0that was driving muscle protein synthesis, and that valine and isoleucine were not having as much of an effect.\u201d<\/p>\n
While valine and isoleucine are critical to muscle building, they don\u2019t play the same signaling role as leucine.<\/p>\n
While structured a little differently from other essential amino acids, BCAAs\u00a0are\u00a0EAAs, so comparing the two can be problematic. Furthermore,\u00a0all EAAs, including BCAAs, are essential to protein synthesis, as well as other biological functions related to normal growth and development.<\/p>\n
EAAs are only \u201cbetter\u201d than BCAAs in that they represent a more complete grouping of necessary amino acids.<\/p>\n
<\/p>\n
When choosing between BCAA or EAA supplements, Falcone\u2019s recommendation is to opt for a well-balanced EAA supplement that meets the\u00a0daily requirements\u00a0for adults and contains between 700 and 3,000 milligrams of leucine. This formula will provide your body with the complete profile of EAAs that it needs to build and repair tissues.<\/p>\n
A protein supplement like Beachbody Performance Recover is also a great option, as it contains EAAs.* However, protein supplements are typically higher in calories than BCAA supplements, and many of them contain fiber, making them a bit heavier than EAA supplements. So, you (and your digestive system) may prefer to save your protein shakes for the post-workout recovery window.<\/p>\n
According to Falcone, as well as some\u00a0studies\u00a0on the efficacy of supplementing with BCAAs, there\u2019s no reason to take them separately. Yes, leucine signals protein synthesis, but without the other EAAs, there\u2019s nothing to trigger.<\/p>\n
\u201cEssentially, it\u2019s like having the contractor, but not all the bricks,\u201d Falcone says. \u201cYou need all the bricks there for the contractor to be able to do their job.\u201d<\/p>\n
