  1. What are branched-chain amino acids (BCAAs) and what do they do?
    Branched-chain amino acids (BCAAs) are three essential amino acids—leucine, isoleucine and valine—that play a key role in muscle protein synthesis and muscle metabolism. Because the body cannot produce these amino acids on its own, they must be obtained through diet or supplementation. Swanson Branched-Chain Amino Acids provides these essential nutrients to help support muscle recovery, lean muscle maintenance and exercise performance as part of an active lifestyle.
  2. How do BCAAs support muscle recovery after exercise?
    BCAAs help support muscle recovery by providing the essential amino acids muscles need following exercise. Leucine, in particular, plays an important role in stimulating muscle protein synthesis, while isoleucine and valine support normal muscle metabolism and energy production. Swanson Branched-Chain Amino Acids can be a valuable addition to your post-workout routine to support recovery and maintain healthy muscle tissue.
  3. Can BCAAs help support lean muscle maintenance?
    Yes. BCAAs help support the maintenance of lean muscle by providing essential building blocks for muscle protein synthesis. When combined with regular resistance exercise and adequate dietary protein, Swanson Branched-Chain Amino Acids helps support healthy muscle maintenance, strength and overall physical performance.
  4. When is the best time to take a BCAA supplement?
    Swanson Branched-Chain Amino Acids can be taken before, during or after exercise, depending on your fitness goals and routine. Many active individuals choose to take BCAAs around their workouts to support muscle recovery and exercise performance. They may also be taken between meals to help supplement daily amino acid intake. Always follow the suggested serving directions on the product label.
  5. What makes Swanson Branched-Chain Amino Acids a good choice?
    Swanson Branched-Chain Amino Acids delivers the three essential BCAAs—leucine, isoleucine and valine—in one convenient capsule formula. Because these amino acids are directly involved in muscle protein synthesis and recovery, they provide targeted nutritional support for athletes, fitness enthusiasts and anyone looking to support healthy muscle function, exercise recovery and an active lifestyle.
  6. Is Swanson Branched-Chain Amino Acids non-GMO?
    Yes. Swanson Branched-Chain Amino Acids is made with non-GMO ingredients, making it a great choice for individuals seeking high-quality sports nutrition that aligns with a non-GMO lifestyle. This formula provides the essential branched-chain amino acids leucine, isoleucine and valine to support muscle recovery, lean muscle maintenance and exercise performance as part of an active, healthy lifestyle.
