I have not looked at BCAAs as a dose or amount issue. It is just something to be aware of and try to increase in one's diet. Food sources for BCAA's are: whey, and milk proteins, beef, chicken, pork, fish, soy proteins, eggs, baked beans, whole wheat, brown rice, almonds, brazil nuts, pumpkins seeds, lima beans, chick peas, cashew nuts, lentils, and corn. I'd limit the soy, especially fermented soy. It has negatives for the brain. (free glutamate).

When I am in a over-stimulating environment and start to notice the ambient sounds, I put my foam ear plugs in. They cut out much of the ambient sound so I can extend the time in the environment. I can still converse with them in.
