If you are low on magnesium it should. If not, then probably won’t make a big difference (A lot of people don’t get enough Mg in their diet though, so odds are it will hep. Mg tends to get more depleted in prep as well. Relatively cheap too). I’m sure Matt will chime in with his 2 cents as well.
I’m curious Matt, are the EAAs you use a unflavored bulk powder? Do you think they would make a difference for someone who trains fasted? I know it’s not ideal, but my digestion is such a mess right now that I get my best workouts on an empty stomach. I am working with a practitioner on shoring up my digestive health, but for now fasted workouts are how I can maintain quality training sessions.
