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.
Good answer bro. I mean I like muscle but not too much. A body builder will not be good at boxing or jiu Jitsu. They are totally different sports. I have chosen martial arts. I may get some BCAAs and take them between meals and preworkout just to see if they help performance. I was never gonna be a BB or power lifter as much as I tried back in the 90s and early 2000s. My frame is very thin and long. I am built for endurance, not power. But I have embraced that and still love and respect power lifting and BB.
