What to know

Heavily marketed to lifters, but if you already eat enough complete protein (or take whey), separate BCAAs add little. They're a subset of what protein already provides.

Interactions & cautions

  • Low risk; largely redundant with adequate protein.

Do you actually need it?

Eating enough protein? BCAAs are mostly redundant.
