Question

Do I need to take BCAAs?

Short Answer

BCAAs (branch chained amino acids) are not needed if you have an adequate daily protein intake.

Long Answer

High quality protein in our diets is already made of 15-25% of BCAAs.[citation needed]

A 2015 study by Dieter et al. found that supplementation with additional BCAAs actually caused a slow down in resting metabolic rate (RMR) by 412 Calories per day.[1]

Further, in 2014, Schoenfeld et al. showed that there is no difference in body composition with sufficient daily protein intake when comparing fasted vs fed cardio.[2]
