Protein supplements are popular in the world of sports, especially among physically active individuals, due to the crucial role of protein in muscle building and recovery. Protein accounts for 15–20% of human body mass and is the main component of skeletal muscles, as well as tissues such as bones, cartilage, skin, and blood. It is essential for the production of enzymes, hormones, and other regulatory compounds.
Protein requirements in athletes are higher than in sedentary individuals, ranging from 1.2 to 1.6 g/kg of body weight per day, which supports post-exercise protein recovery. For athletes aiming to reduce body fat while maintaining muscle mass, recommendations may increase to 1.6–2.4 g/kg. It is also important to distribute protein intake throughout the day, with a recommended intake of 0.3–0.4 g/kg per meal or snack, corresponding to 15–30 g of protein per serving.
Although most athletes can meet their protein needs through a proper diet, protein supplements can be useful in certain situations. Their use may help provide rapidly absorbed protein after training, supplement protein in meals with low protein content, or support athletes with low appetite or limited access to protein-rich foods.
The most popular types of protein supplements include whey proteins (WPC, WPI, WPH), casein, soy protein, and plant-based proteins (e.g., pea, hemp, rice). Whey proteins are high-quality animal-derived proteins rich in branched-chain amino acids, particularly leucine, which plays a key role in anabolic processes.
It is important for athletes to decide on protein supplementation after carefully considering their needs, goals, and training load. Protein supplements do not replace food and should be used as a dietary supplement. Excessive consumption of supplements may limit the intake of other nutrients, such as vitamins and minerals, which are provided by whole food protein sources.


7Nutrition Whey Isolate 90 is a premium whey protein isolate containing an impressive 90 g of protein (dry matter) per 100 g – for the natural version. Thanks to microfiltration, it features an excellent amino acid profile and very low fat and carbohydrate content. This makes it ideal for individuals aiming to build muscle mass, improve recovery after training, and maintain proper energy levels throughout the day.
The isolate is easy to dissolve, making it a convenient addition to shakes, smoothies, or oatmeal—anywhere you need to optimize protein intake. The product is obtained through microfiltration, a modern protein production method that ensures very high purity while minimizing nutrient loss. Unlike other filtration methods, microfiltration does not denature the protein, meaning it retains its natural structure and properties. As a result, it is more bioavailable, which is crucial for effective recovery and muscle growth.
Whey Protein Isolate (WPI) is one of the purest and most popular forms of protein used in sports supplementation. It is derived from whey, the liquid by-product of cheese production. Whey undergoes multi-stage filtration to produce isolate—a product characterized by high protein content and low fat and carbohydrate levels.
Compared to whey protein concentrate (WPC), isolate has a higher protein content due to an additional filtration step that removes more fat and lactose, leaving almost pure protein.
Whey protein isolate is characterized by an exceptionally high biological value (BV), meaning it is very efficiently utilized by the body. Its BV is approximately 104, making it one of the highest-rated protein sources, surpassing others such as egg protein (BV of 100) and plant proteins, which typically have lower values.
Whey protein isolate provides a complete profile of essential amino acids, meaning it contains all amino acids the body cannot produce on its own. It is particularly rich in branched-chain amino acids (BCAAs), including leucine, isoleucine, and valine, which play a crucial role in muscle protein synthesis.
Leucine, in particular, is considered the primary activator of muscle protein synthesis, acting as an anabolic signal for muscle cells. Studies show that the high leucine content in whey isolate significantly enhances post-exercise anabolic processes, leading to faster recovery and muscle growth.
