Branched-chain amino acids (leucine, isoleucine, valine) for muscle support
We rank BCAA by price per gram of active ingredient - not by pack size - so a bigger tub with a worse price per dose can't outrank a smaller one that's actually cheaper.
BCAA stands for branched-chain amino acids. These are a group of three specific essential amino acids, which are the building blocks of protein that the body cannot make on its own and must get from food or supplements. The three amino acids included are leucine, isoleucine, and valine.
These supplements are primarily used for muscle support. They are often taken by people who exercise to help protect muscle tissue from breaking down and to support the process of muscle repair.
To create the supplement, the three amino acids are produced through a process called fermentation, where bacteria are used to create the specific molecules. These are then purified and dried into a powder. This powder is then either put into capsules or mixed with flavourings to be sold as a drink mix.
The cost of these supplements is generally mid-range. This is because the fermentation process used to create the amino acids is a standard industrial method, but the need to source and balance three different specific amino acids makes it slightly more complex than producing a single-ingredient supplement.

| reduce markers of muscle damage, attenuate delayed-onset muscle soreness and preserve maximal voluntary contraction | 20 grams per day | established |
| enhance strength and preserve lean mass | 5 grams per day to 28 grams per day | established |
| maintain lean body mass and preserve bench press 1RM under caloric restriction | 9 grams per day | established |
| reduce muscle soreness and improve isometric strength recovery | 10 grams per day | established |
