Protein supplements are popular in the world of sports, especially among physically active individuals, due to the key role protein plays in building and regenerating muscles. Protein accounts for 15–20% of the 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 compounds with regulatory functions.
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 allows for protein rebuilding after training. 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 recommendation of consuming 0.3–0.4 g/kg per meal or snack, which corresponds to 15–30 g of protein per serving.
Although most athletes can meet their protein requirements through a proper diet, protein supplements can be useful in certain situations. Their use can help provide fast-absorbing protein after training, facilitate protein intake in meals low in this nutrient, 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, especially leucine, which plays a key role in anabolic processes.
It is important for athletes to consider their needs, goals, and training load before deciding to use protein supplementation. Protein supplements do not replace food and should be used as a complement to the diet. Excessive intake of supplements may limit the intake of other nutrients, such as vitamins and minerals, which are provided by whole protein-rich foods.
7Nutrition Whey Isolate 90 is an exceptional whey protein isolate containing an impressive 90 g of protein (dry matter) per 100 g – for the natural version. Thanks to microfiltration, this product features an excellent amino acid profile and very low fat and carbohydrate content. This formula makes it ideal for individuals aiming to build muscle mass, improve post-workout recovery, and maintain proper energy levels throughout the day. The isolate dissolves easily, making it a convenient addition to shakes, smoothies, or oatmeal—wherever you need to optimize protein intake. The product is obtained through microfiltration, a modern protein production method that ensures very high purity while minimizing the loss of nutritional value. Unlike other filtration methods, microfiltration does not cause protein denaturation, meaning it retains its natural properties and structure. As a result, protein obtained through this method is better absorbed by the body, which is crucial for effective recovery and muscle-building processes.
Whey Protein Isolate (WPI) is one of the purest and most popular types of protein used in sports supplementation. It is produced from whey, the liquid by-product of cheese production. Whey, being a rich source of protein, undergoes multi-stage filtration, resulting in whey protein isolate—a product characterized by high protein content and low fat and carbohydrate levels. Thanks to these properties, WPI has gained immense popularity among athletes and individuals aiming to increase muscle mass, improve recovery, and maintain a fit physique. Compared to whey protein concentrate (WPC), isolate contains a higher percentage of protein, making it a more concentrated source. The difference in protein content between WPI and WPC results from an additional filtration stage that removes more fat and lactose, leaving almost pure protein.
Whey protein isolate is characterized by an exceptionally high biological value (BV – Biological Value), meaning it is used very efficiently by the body. The BV of whey protein isolate is approximately 104, making it one of the highest-rated protein sources, surpassing other popular sources such as egg protein (BV of 100) or plant proteins, which typically have lower biological value.
Whey protein isolate provides a complete profile of essential amino acids, meaning it contains all amino acids that the body cannot produce on its own. It is particularly rich in branched-chain amino acids (BCAA – Branched-Chain Amino Acids), including leucine, isoleucine, and valine. These three amino acids play a key role in muscle protein synthesis, making WPI an ideal choice for those aiming to build and regenerate muscle.
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 protein isolate significantly enhances anabolic processes after training, leading to faster recovery and muscle growth.
