You're funny!
In my case, I don't think the BCAAs help with PEM due offsetting catabolism. I think it's a different mechanism altogether and the articles explain more.
The BCAAs do help me with PEM, which is great, but unfortunately do not increase my baseline energy.
A few things that have helped me with baseline energy are: B1, B6, folate, methylcobalamin (I recently switched to Blue Bonnet liquid 5000 mcg. and take it 3 x day, and that is helping my baseline energy to my surprise - I had thought I was up on my B12); also potassium, and phosphorus as needed. The phosphorus is a little tricky, I think it has to do with refeeding syndrome. - e.g., the B1 initially boosted my energy a lot, and then it dropped - boom! and somehow I discovered it was depleting phosphorus (was already up on potassium). The same thing happened when I increased the B12. I did another post on phosphorus. I know we have to be careful with it but I think hypophosphatemia is overlooked most of the time.
One more thing - speaking of phosphorus - I am going to retry arginine. Someone posted awhile ago about arginine helping a lot with energy and to prevent PEM and I tried it and it helped a little and then boom! I went down again. I did not think of hypophosphatemia at that time but am thinking of it now and am going to retry the arginine and add in phosphorus if needed (mainly in the form of kefir or yogurt and sunflower seeds, and maybe a little monosodium phosphate) and see what happens.
