Compare every Amino Acids product across UK retailers on Suppio, ranked by true value - price per active dose, not pack size. Prices refreshed daily.
Building blocks of protein used for muscle repair and growth
We rank Amino Acids 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.
Amino acids are the organic building blocks that combine to create proteins. They are small molecules that the body uses to construct and repair tissues throughout the entire system.
These supplements are primarily used to support the body during physical exertion. They are used for:
Commercial amino acid supplements are produced through the industrial breakdown of protein sources. Manufacturers use a process called hydrolysis, which uses water and enzymes to split large protein chains into individual amino acids. These are then purified, dried into a powder, and packed into capsules or tubs.
These supplements generally sit in a mid-range price bracket. This is because the cost of sourcing raw protein materials is moderate, and the chemical process used to isolate the specific amino acids is well-established and common across the industry.
