Do EAA's help build muscle or only for recovery?

[redsfinnared]

been taking amino iv for a while for the muscle recovery but wondering do EAA's also help build more muscle? eaa/bcaa's are marketed saying it increases muscle protein synthesis (is that the same as building muscle?)

eaa's can be beneficial to use while training. however your overall diet and training is FAR superior.

Biggest factor by far for "building muscle" is going to be your diet and eating in a calorie surplus, your training is also a large factor.

I wouldn't waste your money on BCAA/EEA sups OP unless your training fasted or taking them when meals are more than 4 hours apart. HOWEVER, if your goal is to build muscle then eat in a calorie surplus, hit your macros, and then you won't need to worry about any BCAA/EEA's. Remember whole protein sources (i.e meat, dairy, eggs) have all the aminos you need.

Best recovery sup is FOOD and REST.

consistent resistance training with progressive overload and diet will always be the biggest factors to muscle growth.

scivation has a study coming soon showing bcaas as beneficial for muscle growth when taken as an intra.

Correct

WHY EAA's more important than BCAA intra-workout:
but EAAs may impart some endurance-like effects that BCAAs simply cannot.

This is the only study done in trained humans consuming EAAs during the workout. These are legit, military-trained personnel doing both resistance and endurance work.

The findings?

"In summary, consumption of a 10-g dose of EAA enriched with leucine during moderate endurance-type exercise stimulated increased MPS when compared with an isonitrogenous EAA supplement with an amino acid profile consistent with high-quality proteins. These data indicate that increasing leucine availability during steady state exercise promotes skeletal muscle protein anabolism and spares endogenous protein."


Cliffs:

These EAAs increased postworkout MPS by 33% when consumed during exercise
The drink with the highest leucine content spared muscle to the greatest degree
