Life Extension Branched Chain Amino Acids (BCAAs), leucine, isoleucine, valine, Promotes Muscle Recovery After Exercise, Gluten-Free, Non-GMO, 90 Capsules
- For exercise performance—Branched chain amino acids (BCAAs) are well-known by strength, endurance and everyday athletes alike for supporting peak strength and endurance performance during their workouts.
- Encourages muscle recovery—While BCAAs support performance during exercise, they are equally as important for post-exercise. These amino acids help maintain skeletal muscle and promote overall muscle recovery, especially after a tough workout.
- Supports protein synthesis—BCAAs play a vital role in protein synthesis in important parts of the body, including the muscles and the liver. But the body can’t produce it on its own, making food and supplement sources necessary.
- Ingredients matter—We use the finest raw ingredients with the quality and purity you deserve. The majority of our products are non-GMO, gluten-free and manufactured in the USA—and a Certificate of Analysis is available for every one.
- Live your healthiest life—We believe the answers to a healthier life are in reach, and that scientific research is the key to getting there. That’s why so many of our formulas feature specific ingredients and amounts based on scientific studies.
