I can tell you why I use them. Due to muscle breakdown. Througout the day. BCAA are very important. If you are not competing. I can't answer for you. I know I need to stay hydrated by sipping water throughout the day and adding branched chain amino acids. Liquid or capsule without extra carbs or calories from drinks or shakes. I guess you would not notice or matter to you. Those seriouly in the game. Have a protein, carb and fat daily limit. Depending the season. We count our food intake. So very good Idea to stay hydrated and pop BCAA within a given time each day. No one wants to walk around flat. That works for you but not those seriouly in the game.
I'm sure you're not looking to put on quality muscle. You're just maintain life.
