BCAAs (Branched-Chain Amino Acids) are a group of three essential amino acids: leucine, isoleucine and valine. These amino acids are particularly important for our muscles. Due to their rapid absorption into the bloodstream, BCAAs increase muscle growth and repair, improve exercise performance and reduce fatigue during workouts.
The body can’t make these essential amino acids; therefore, you have to get them from your diet. Rich dietary sources of BCAAs include meat, dairy, egg, poultry, fish, legumes, nuts and other foods rich in protein. Usually, a balanced diet will contain all the essential amino acids needed to build muscle.
However, when doing intermittent fasting you might not be able to replenish BCAAs as quickly. Intermittent fasting means a limited eating window; therefore it’s not as easy to consume the same amount of food.
Particularly for anyone combining intermittent fasting and exercise, BCAA can become their new favorite supplement. Studies show that BCAA supplements reduce exercise fatigue and improve endurance resulting in more enjoyable and productive workouts. Using BCAA as a supplement also helps with muscle growth and reduces the annoying post-workout soreness.
