Compare every BCAAs product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.
Branched-chain amino acids (leucine, isoleucine, valine) for muscle support
We rank BCAAs 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.
BCAAs are branched-chain amino acids, which are the building blocks used by the body to create proteins. This specific group consists of three essential amino acids: leucine, isoleucine, and valine. They are called essential because the body cannot produce them on its own, meaning they must be obtained through food or supplements.
These amino acids are primarily used to support muscle health. They are often taken to help reduce muscle soreness and prevent the breakdown of muscle tissue during intense exercise.
To create these supplements, the specific amino acids are typically extracted from protein sources through a process called fermentation. This involves using microorganisms to produce the amino acids in large tanks. Once produced, the substances are purified and dried into a powder, which is then either sold as is or put into capsules.
BCAAs generally fall into a mid-range price category. This is because while the raw materials are not excessively rare, the industrial fermentation and purification processes required to isolate the three specific amino acids add to the production cost.
| Purpose | Typical studied dose | Evidence |
|---|---|---|
| stimulate muscle protein synthesis, reduce muscle protein breakdown, exercise-induced muscle damage and fatigue | 77 milligrams per kilogram to 3 grams per kilogram | emerging |
| reduce markers of muscle damage, attenuate delayed-onset muscle soreness and preserve maximal voluntary contraction | 20 grams per day | emerging |
| reduce muscle soreness and speed recovery | 5 to 10 grams per day | limited |
| decrease muscle damage markers | 15 grams per day | emerging |
| improve recovery and reduce fatigue | 18 to 20 grams per day | limited |
| improve endurance and reduce fatigue during sessions | 84 milligrams per kilogram | emerging |
| maintaining positive nitrogen balance following traumatic brain injury | intravenous infusion of BCAA-enriched formula (leucine 154 percent, isoleucine 153 percent, and valine 174 percent of standard formula) | limited |
Suppio matches identical products across UK retailers by barcode, then ranks by price per active dose rather than sticker price. Value rankings only ever include listings Suppio has independently verified against the live retailer page - unverified data is shown on each product’s own page but excluded from ranking.
