Protein supplements are popular in the world of sports, especially among those actively training, due to the key role of protein in building and repairing muscles. 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 compounds supporting normal physiological functions.
The protein requirement for athletes is higher than for sedentary individuals, amounting to 1.2 to 1.6 g/kg of body weight per day, which allows for protein synthesis after training. For athletes striving to reduce body fat while maintaining muscle mass, recommendations may rise to 1.6-2.4 g/kg. It is also important to spread 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 an appropriate diet, protein supplements may be useful in certain situations. Their use may help provide quickly absorbed protein after training, make it easier to supplement protein in meals low in this nutrient, or support athletes with a low appetite or in conditions where access to protein-rich food is limited.
The most popular types of protein supplements are whey proteins (WPC, WPI, WPH), casein, soy protein, and plant-based proteins (e.g., from peas, hemp, rice). Whey proteins are high-quality animal-based proteins rich in branched-chain amino acids, especially 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 part of a varied and balanced diet. Excessive consumption of supplements may limit access to other nutrients, such as vitamins and minerals, which are provided by whole protein food sources.
7Nutrition Whey Isolate 90 is a unique whey protein isolate that contains an impressive 87 g of protein (in dry matter) per 100 g – for the natural version. Thanks to the microfiltration used, this product is characterised by an excellent amino acid profile and a very low fat and carbohydrate content. This formula makes it ideal for people striving to build muscle mass, support recovery after workouts, and maintain an appropriate level of energy throughout the day. The isolate is also easy to dissolve, making it a convenient addition to shakes, smoothies, or oatmeal—wherever you need to optimise protein intake. The product was obtained through microfiltration, a modern method of protein production that allows for obtaining protein of very high purity while simultaneously minimising the loss of nutritional value. Unlike other filtration methods, microfiltration does not lead to protein denaturation, which means it retains its natural properties and structures. As a result, protein obtained using this method is highly bioavailable to the body, which is crucial for the effectiveness of recovery processes and muscle mass building.
Whey Protein Isolate (WPI) is one of the purest and most popular types of protein used in sports nutrition. It is a product obtained from whey, which is the liquid residue after the cheese production process. Whey, being a rich source of protein, undergoes multi-stage filtration, resulting in whey protein isolate – a product characterised by a high protein content and low fat and carbohydrate content. Thanks to these features, WPI has gained huge popularity among athletes and people striving to increase muscle mass, support recovery, and maintain an appropriate physique. Compared to Whey Protein Concentrate (WPC), the isolate is characterised by a higher protein content, which makes it a more concentrated source of this nutrient. The difference in protein content between WPI and WPC results from an additional filtration stage, which removes a larger amount of fat and lactose, leaving almost exclusively protein.
Whey protein isolate is characterised by an extremely high Biological Value (BV), which means that it is very effectively utilised by the body. The BV of whey protein isolate is approximately 104, which makes it one of the highest-rated sources of protein, surpassing in this respect other popular sources such as egg proteins (BV of 100) or plant-based proteins, which usually have a lower biological value.
Whey protein isolate provides a full profile of essential amino acids, which means it contains all the amino acids that the body is unable to 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 the muscle protein synthesis process, making WPI an ideal choice for people striving for muscle building and recovery.
Leucine, in particular, is considered the main activator of muscle protein synthesis, acting as an anabolic signal for muscle cells. Studies suggest that the high leucine content in whey protein isolate contributes to a significant intensification of anabolic processes after training, which leads to faster recovery and muscle growth.
