Bcaa

Definition

BCAAs, or branched-chain amino acids, are essential nutrients that help support muscle growth and repair.

Scientific / Technical Definition

Branched-chain amino acids (BCAAs) are a group of three essential amino acids: leucine, isoleucine, and valine. They are named for their chemical structure that includes a branch off the main chain of atoms. BCAAs are crucial in protein synthesis, and muscle metabolism, and can be used as a quick source of energy during physical exertion.

Benefits

• Promotes muscle growth.
• Reduces muscle soreness after exercise.
• Decreases exercise-induced fatigue.
• Prevents muscle breakdown.
• Supports immune system function.

Examples

• Chicken
• Eggs
• Dairy products
• Whey protein
• Soy protein

Additional Information

• effects: BCAAs play several roles in muscle metabolism and serve as a key energy source during prolonged exercise.
