BCAAs were long considered a direct stimulator of muscle growth, but more recent reviews of the evidence challenge this. Wolfe (2017) showed that BCAAs alone – without the remaining essential amino acids – do not stimulate muscle protein synthesis, and when administered intravenously they even reduced overall muscle protein turnover. A more reliable benefit of BCAAs is a reduction in muscle soreness (DOMS) and markers of muscle damage after intense exercise (Fouré and Bendahan, 2017). For actual muscle growth, a sufficient total daily protein intake from all sources is key, while BCAAs can act as additional support for recovery rather than a standalone muscle-building tool.

Clinical studies on reducing exercise-induced muscle soreness (DOMS) have mostly used total daily BCAA doses of roughly 5 to 20 g, with a more recent meta-regression showing that higher doses and longer supplementation periods (more than 7 days) produce better results (Salem et al., 2024). At 5 g per day, as recommended by the manufacturer for this product, you are at the lower end of this range – so an effect may be present, but is likely less pronounced than with products offering a higher recommended daily dose. Do not exceed the recommended daily dose stated on the label without consulting a professional.

This product intentionally contains no added sweeteners, flavourings or colourings – it consists only of the three BCAA amino acids, an emulsifier (sunflower lecithin) and citric acid as an acidity regulator. This means a cleaner formula without the artificial sweetener sucralose found in most other BCAA products, but also a more pronounced, sour taste, which is also noted by users in reviews. If the taste is too intense for you, you can mix it with more water or add it to another beverage.

The label states that the product may contain traces of milk, soy, eggs, celery, sulphites, fish, crustaceans and nuts due to possible cross-contamination during production, not because these ingredients are part of the formula itself. For people with mild sensitivity, this usually poses no risk, but for those with a diagnosed, severe allergy (e.g. to nuts), we recommend consulting an allergist or doctor before use, as even trace amounts can trigger a reaction in highly sensitive individuals.
