RCSS Glutamine XS by Ronnie Coleman Signature Series is a powder for anyone who wants to supplement their amino acid intake around training. Available in 2 sizes from 1000g to 300g.

Amino Acids Explained Briefly

Amino acids are the building blocks that make up proteins. Nine of them are essential (EAAs) – the body cannot produce them itself; they must come from food. Three of these nine are the branched-chain BCAAs: Leucine, Isoleucine, and Valine. As supplements, they come in many forms: EAA and BCAA powders as fruity training drinks, capsules for on the go, and individual amino acids like Glutamine, Citrulline, or Tyrosine. If you already cover your protein intake through meals and shakes, amino acid products offer one main advantage: flexibility around training – for example, as a low-calorie intra-workout drink.

What to look for when buying?

First, decide between EAA (all nine essential) and BCAA (only three) – EAAs offer a more complete profile. Check the quantities per serving in the declaration and the ratio of amino acids (for BCAAs, typically 2:1:1). Powder offers the best price per serving, while capsules are the most convenient for on-the-go consumption.
