Compare every BCAA product across UK retailers on Suppio, ranked by true value - price per serving, not pack size. Prices refreshed daily.
BCAA stands for branched-chain amino acids. These are a group of three specific amino acids, which are the basic building blocks that make up protein: leucine, isoleucine, and valine.
These supplements are primarily used by people who exercise to help prevent muscle breakdown. They are often taken to reduce soreness after a workout and to support the recovery of muscle tissue.
While BCAAs only provide three specific amino acids, EAA (Essential Amino Acids) provides all nine that the human body cannot make on its own.
| Feature | BCAA | EAA |
|---|---|---|
| Composition | Only 3 amino acids | All 9 essential amino acids |
| Primary Goal | Reducing muscle breakdown | Providing all blocks for muscle growth |
| Scope | Narrow and targeted | Comprehensive |
To make these supplements, manufacturers start with a protein source, often fermented plant matter or animal proteins. They use a process called hydrolysis to break the protein down into individual amino acids. These are then isolated and purified to ensure only the three specific branched-chain acids remain, which are then dried into a powder or put into capsules.
These products generally sit in a mid-range price bracket. This is because the process of isolating three specific amino acids is more complex than selling a basic protein powder, but the raw materials are widely available and produced at a large industrial scale.
