An Important Research Update on BCAAs and Muscle Recovery
This product provides 2000mg of BCAAs (branched-chain amino acids: leucine, isoleucine, valine) in a 2:1:1 ratio, alongside vitamin B6 (2.8mg) and B12 (500μg). Leucine specifically is understood to be a particularly potent trigger for initiating muscle protein synthesis, which is the basis for BCAAs’ popularity in fitness nutrition.
It’s worth being clear about an important, evolving piece of research: Branched-chain amino acids supplements were marketed for years on the assumption that these three amino acids alone were enough to drive muscle building, but more recent research has clarified that BCAAs alone cannot fully stimulate muscle protein synthesis without the other six essential amino acids also being present.
A 2017 review in the Journal of the International Society of Sports Nutrition concluded Branched-chain amino acids alone don’t produce a meaningful anabolic response on their own — this is why EAA (all nine essential amino acids) formulations are increasingly considered the more complete, evidence-supported choice for muscle protein synthesis specifically, even though BCAAs still play a genuine signalling role within that bigger picture. If you’re eating adequate overall protein through your diet, you’re likely already getting the other essential amino acids BCAAs need to work alongside; if not, a complete protein source or EAA supplement may be more effective for muscle-building goals specifically than Branched-chain amino acids alone.
Vitamin B12 as methylcobalamin and B6 as pyridoxine hydrochloride have established, EU-authorised roles in normal energy metabolism and reduced tiredness and fatigue, genuinely useful alongside training-related nutrition regardless of the BCAA-specific consideration above.
Vegan, non-GMO, gluten-free, lactose-free, manufactured to GMP standards in the UK. Take 2 tablets daily, preferably with a meal, or as directed by a healthcare professional. Not suitable for under-18s. Speak to your GP before use if you take regular medication, have an existing health condition, or have kidney disease, given the added protein-metabolism load.

BCAA, CLA, L-Arginine and More: Amino Acids Explained
BCAA, CLA, L-arginine, taurine, glutamine and NAC are usually bought individually for a specific goal, rather than as a group. Here's what UK-relevant research actually shows for each one — including a genuine cardiac safety finding for one of them that's worth knowing before you buy.
