Instantized BCAA By Optimum Nutrition - Amino Acids

What is ON BCAA Powder?

Optimum Nutrition Instantized BCAA Powder is used for muscle recovery, energy and endurance. BCAAs have been used by strength-training and endurance athletes alike to activate protein synthesis and reduce muscle breakdown caused by intense training. Our Instantized BCAA 5000 Powder is made using a proprietary process that mixes easily and keeps the BCAAs suspended longer so they do not readily settle to the bottom of the glass. Because if you can't drink your BCAAs, they can't help your performance.

How does ON BCAA Powder work?


  • Micronized L-Leucine: 2.5 g - Supports lean muscle tissue and provides energy. †
  • Micronized L-Isoleucine: 1.25 g - Aids in protein synthesis and glucose metabolism. †
  • Micronized L-Valine: 1.25 g - Can promote muscle recovery and extended endurance. †

  7. An excellent product
    Overall Product Review
    Being a consummate gym goer, I have experience enough to be able to tell a good product from an average one.
    This is, hands down, the best BCAA supplement I have ever taken, and it has done wonders to optimize my exercise routine as well as lessening the recovery time between sessions.
