Protein supplements are popular in the world of sports, especially among physically active individuals, due to the crucial role protein plays in muscle building and recovery. Protein constitutes 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 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 supports post-exercise protein rebuilding. 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 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 may be useful in certain situations. Their use can help deliver fast-absorbing proteins post-workout, supplement meals low in protein, 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 that athletes 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 intake may limit the intake of other nutrients such as vitamins and minerals provided by whole protein-rich foods.
7Nutrition Whey Isolate 90 is a premium whey protein isolate containing an impressive 90 g of protein (in dry matter) per 100 g – for the unflavored 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—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 protein, meaning it preserves its natural properties and structure. As a result, protein obtained this way is better absorbed by the body, which is crucial for effective recovery and muscle growth.
Whey Protein Isolate (WPI) is one of the purest and most popular types of protein used in sports supplementation. It is derived from whey, the liquid by-product of cheese production. Whey, being a rich protein source, undergoes multi-stage filtration, resulting in whey protein isolate—a product characterized by high protein content and low fat and carbohydrate levels. Due to these features, WPI has gained great popularity among athletes and individuals aiming to increase muscle mass, improve recovery, and maintain physique. Compared to whey protein concentrate (WPC), isolate contains more protein, making it a more concentrated source. This difference 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 very efficiently utilized by the body. The BV of whey protein isolate is approximately 104, making it one of the highest-rated protein sources, surpassing others such as egg protein (BV of 100) or plant proteins, which typically have lower biological values.
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), 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 recover muscle.
Leucine, in particular, is considered the primary activator of muscle protein synthesis, acting as an anabolic signal for muscle cells. Research shows that the high leucine content in whey protein isolate significantly enhances anabolic processes after exercise, leading to faster recovery and muscle growth.
