> There is the additional fact that even if you stimulate protein synthesis with BCAA or leucine specifically, it won’t matter if there aren’t sufficient amounts of the other aminos present. You can turn on protein synthesis all you want with BCAA or leucine, without the other building blocks for skeletal muscle, it won’t make any difference.
>
> There is also the simple fact that the primary stimulus for increased muscle in the body is training, not protein. Most Americans eat tons of protein and get lots of BCAA, they aren’t growing muscle because they aren’t training and giving the body a stimulus to store the extra protein.
>
> You can turn on all the protein synthesis that you want with dietary modifications, as it turns out the body simply breaks down more protein later in the day to compensate. Unless someone is training, muscle mass simply doesn’t increase due to these kinds of dietary manipulations.
>
> Finally, as I discussed in the [previous part on dietary protein quality](https://bodyrecomposition.com/nutrition/protein-sources-quality-part-1), all high quality proteins contain lots of the BCAA in the first place, ranging from 15-25% depending on the source (most sources are around 15%, casein comes in around 20% and whey can range from 23-25% BCAA). Of that BCAA, a fairly large chunk is leucine.
>
> A bodybuilder consuming say 250 grams of protein (e.g. 1.5 grams per pound at around 170 pounds) will be getting, somewhere between 40-50 grams of BCAA depending on the sources. Someone consuming a lot of whey or casein will get a bit more, someone living on nothing but meat will get slightly less. But someone eating that much protein is already getting a lot of leucine in their diet, at each meal; throwing in another gram or two is not going to do much.
>
> The same holds for BCAA as a whole; I just see it as unlikely that, unless someone adds a truly absurd amount, it’s going to matter in the context of the already large amount of BCAA coming in. And, as noted above, unfortunately the studies don’t really answer that question; they all look at BCAA supplementation under conditions of what I consider inadequate protein in the first place.
