How BCAAs Can Take Your Performance to the Next Level


Most people don’t understand why they need a branched-chain amino-acid (BCAA) product. Why take BCAAs rather than protein powder?

Scivation’s original BCAA product, Xtend, is one of the best-selling ever. What persuaded you to change the formula with Xtend Perform?

It’s the same core formula, but we wanted to add 2 grams of Peak O2—a blend of six different organic, non-GMO mushrooms grown in the U.S.—per serving. In one University of North Carolina study, subjects who took 2 grams twice a day had a lot of improvement in oxygen efficiency. In general, the heart rate recovers more quickly, and time to exhaustion increases. I find I recover faster between sets, so I can do more sets or get out of the gym sooner. You should see results in about seven days.
