24 g of protein per 30-gram scoop falls within the range recommended by the ISSN for a single meal to stimulate muscle protein synthesis (approximately 0.25–0.40 g/kg body weight, or practically 20–40 g per meal) (Jäger et al., 2017). However, for long-term muscle mass building, total daily protein intake is what matters most – meta-analyses show that benefits for muscle mass and strength during resistance training increase up to approximately 1.6 g/kg body weight per day, above which the additional effect diminishes (Morton et al., 2018). A single serving of this product is thus a good support, but not a magic formula – what matters more is how much protein you consume throughout the entire day.

The combination of sodium cyclamate, sucralose and saccharin is safe for the general adult population within permitted limits, as these are sweeteners approved in the EU. However, in people with very sensitive digestive tracts, multiple sweeteners at once may increase the likelihood of bloating or mild digestive discomfort compared to products with only a single sweetener. If you notice such symptoms, it makes sense to try a product with fewer sweeteners or to check your tolerance with a smaller dose. In general, there is no evidence of harmful long-term effects of whey protein in healthy adults at usual doses (Vasconcelos et al., 2020).

Compared to concentrate, whey protein isolate has a higher protein content per gram and less lactose and fat, which is why it is considered a somewhat higher-quality form, although milk proteins in general already achieve a very high DIAAS – an indicator of protein digestibility and quality (Herreman et al., 2020). This product contains 60.6% isolate and 35.0% concentrate, which is an above-average combination within this product category. It is important to know, however, that the difference between protein sources is not crucial for long-term muscle building if total daily intake is the same – the advantage of whey lies mainly in its speed of absorption, for example immediately after training.

For this product, the manufacturer (Sportness/dm) does not provide publicly available data on an independent laboratory report testing for heavy metals, microbiology or banned substances. This does not necessarily mean the product is unsafe, as it must comply with legal requirements for food products, but without a publicly published report (e.g. NSF Certified for Sport certification), it is not possible to verify the actual results of a specific batch (NSF International). Independent analyses do show that protein powders can vary in heavy metal contamination between brands (Clean Label Project, 2025), so it makes sense to prioritize products with publicly published test results.
