Branch Chain Amino Acids (BCAA’s) are the building blocks of protein.
20 amino acids are used by the  human body to construct all our proteins.
9 of these Amino Acids are called essential BCAA’s.
3 of these namely Leucine, Isoleucine and Valine make up approximately 33%  of human muscle protein. When these are ingested in free-form like StayLean® BCAA’s they will:

  • assist protein synthesis
  • reduce fatigue
  • speed recovery

StayLean® BCAA is a high-quality free form fermented supplement – suitable to take before, during and after training.



StayLean’s BCCA contains amino acids made only by a natural fermentation process. This means you get maximum purity without the use of any harsh chemical solvents.

Stay Lean’s BCAA powder boasts leucine -7 gms of fermented pure branched chain amino acids providing high levels of leucine to stimulate protein synthesis –  isoleucine and valine in an impressive 5:1:1 ratio, bringing you the strongest blend of fermented BCAAs on the market today.

No artificial chemicals to flavour, only natural healthy ingredients: Turmeric and Beetroot powder.


It is estimated that 95% of brands use BCCAs sourced from animals – extracted from feathers, hair and skin and harsh chemicals are used in the process.

    I love the orange/mango flavour, it is so refreshing during a workout. The Stay Lean products are full of so many great ingredients designed to really make the most of diet and training. They also contain nothing nasty and artificial like so many other supplements.
