Branched-Chain Amino Acids (BCAAs)

Definition

Branched-Chain Amino Acids, or BCAAs, are essential nutrients that help support muscle metabolism and are commonly used to enhance exercise performance.

Scientific / Technical Definition

Branched-Chain Amino Acids consist of three essential amino acids: leucine, isoleucine, and valine. These amino acids have aliphatic side chains with a branch, distinguished by a central carbon atom bound to three or more carbon atoms. BCAAs play crucial roles in protein synthesis and energy production, particularly in skeletal muscles.

Benefits

• Increase muscle growth
• Reduce muscle soreness
• Decrease exercise-induced fatigue
• Prevent muscle wasting
• Support liver health

Examples

• Meat
• Dairy products
• Eggs
• Legumes
• Dietary supplements

Additional Information

• Side effects: High doses of BCAAs may lead to fatigue, loss of coordination, and gastrointestinal problems.
