BCAA & EAA Supplements

Branched-chain amino acids (BCAAs) and essential amino acids (EAAs) are isolated amino acid supplements designed to support muscle protein synthesis and recovery. BCAAs contain three specific amino acids-leucine, isoleucine, and valine-whilst EAAs include all nine amino acids your body cannot produce independently.

BCAAs are more targeted than EAAs, focusing on leucine's role in triggering muscle-building pathways. However, EAAs provide a more complete amino acid profile, including histidine, methionine, phenylalanine, threonine, tryptophan, and lysine, which support broader physiological functions. Compared to whey protein, amino acid supplements offer faster absorption and are free from lactose and carbohydrates, making them lighter options between meals.

These products typically suit athletes, those doing resistance training, or people seeking muscle recovery without substantial calorie intake. They're also useful for individuals with digestive sensitivities or those following intermittent fasting protocols.

When comparing brands, examine the amino acid profile-particularly leucine content in BCAAs, which typically ranges from 2-5 grams per serve. Check the ratio of branched-chain to other amino acids in EAAs. Consider the source (synthetic versus fermented), flavour options, mixability, and added ingredients such as sweeteners or vitamins. Price per gram of amino acids helps establish value, as does whether the product is third-party tested for purity and banned substance compliance.
