Combining three forms of whey has a real basis – hydrolysate is partially pre-digested and absorbed faster, isolate contains less lactose and fat with a higher protein purity, while concentrate serves as the more cost-effective carrier for the rest of the formula. In practice, this means a somewhat more refined profile than products containing only concentrate. However, the manufacturer does not disclose the exact proportion of each of the three forms in the blend, so it's impossible to say with certainty how large a share of the cheaper concentrate actually dominates. Nevertheless, this is a scientifically sound combination, as both isolate and hydrolysate have a higher DIAAS than pure concentrate (Herreman et al., 2020).

Whey protein already contains all essential amino acids on its own, including leucine, which is the key trigger of muscle protein synthesis (Ijaz et al., 2025). The additional 5 g of BCAA per serving therefore supplements the amino acids already present from the whey itself, which can be particularly useful if your overall daily protein intake is otherwise low. Glutamine is not an essential amino acid and the body produces sufficient amounts on its own, so the evidence for an additional benefit of glutamine for muscle growth when protein intake is already adequate is not strong – it's more of an added bonus than a necessary ingredient for achieving results.

The base ingredient is indeed whey protein from milk, but the long allergen list mainly refers to the possibility of cross-contamination at the facility where the product is manufactured – the manufacturer states that the product may contain traces of eggs, celery, sulfites, fish, crustaceans and nuts because other products are also processed in the same facility. This is a standard precautionary label and does not mean these ingredients are intentionally added to the formula. However, if you have a serious allergy to any of the listed substances, we still recommend consulting a doctor or allergist before use, as traces from cross-contamination can trigger a reaction in sensitive individuals.

Protein powders, including whey, are primarily intended to make it easier to reach your total daily protein intake goal, which for active individuals is typically between 1.4 and 2.0 g per kilogram of body weight (Jäger et al., 2017). Since muscles are repaired and built even on rest days, it can make sense to use protein every day if it helps you reach this goal – not just on training days. More important than the exact timing of intake is achieving a sufficient total protein intake throughout the day from all sources, including food.
