The Claim
Many users believe that taking BCAAs can prevent or significantly reduce muscle soreness after exercise, aiding in quicker recovery.
Origin
This belief has been popularized by supplement companies and some early studies suggesting potential benefits.
What Science Says
Research, including several RCTs, indicates that BCAAs may have a modest effect on reducing muscle soreness, but the effect size is small. A systematic review highlighted that while there is some reduction in perceived soreness, it is not significantly greater than placebo or other recovery strategies.
Verdict
Partially True
