Our #1 Pick

Xtend Original BCAA Powder

Scivation · $18-24 · Powder

"The world's #1 selling BCAA supplement for over a decade"

Xtend is the BCAA that defined the category. The 7g BCAA dose is solid, and the electrolyte addition makes it a great intra-workout drink. However, if you're already eating enough protein, standalone BCAAs may not provide additional benefit. Best for fasted training or as a flavored hydration drink.
