Branched-chain amino acids, more commonly known as BCAAs, include the essential amino acids leucine, isoleucine, and valine.

BCAAs differ from other amino acids because they have a branched structure and are the only amino acids that are broken down in skeletal muscle. They’re considered essential because you must consume them through your diet (1).

Athletes and gym-goers commonly take BCAA supplements to enhance performance, reduce soreness, and prevent muscle fatigue (1).

There are many products on the market, which may leave you wondering which are best. This article lists BCAA supplements that meet the following criteria:

  • strict manufacturing standards regarding quality and purity
  • no unnecessary ingredients, such as artificial sweeteners or colorings
  • trusted by healthcare professionals like doctors and dietitians
