Protein supplements are popular supplements in the world of sport, especially among those actively training, due to the key role of protein in building and repairing muscle. Protein accounts for 15-20% of human body mass and is the primary 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 for athletes are higher than for sedentary individuals, ranging from 1.2 to 1.6 g/kg of body weight per day, which allows for the restoration of proteins after training. For athletes aiming for weight loss 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 may meet their protein requirements through a suitable diet, protein supplements may be useful in certain situations. Their use may help in providing fast-absorbing proteins after training, facilitate replenishing protein in meals with low protein content, 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 protein (e.g., from peas, hemp, rice). Whey proteins are high-value proteins of animal origin, 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 a supplement to the diet. Excessive consumption of supplements may limit access to other nutrients, such as vitamins and minerals, which are provided by complete protein products.
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. Such a formula makes it ideal for people aiming to build muscle mass, improve post-workout recovery, and maintain an appropriate energy level throughout the day. The isolate is also easy to dissolve, which makes it a convenient addition to shakes, smoothies, or porridge, i.e., anywhere you need to optimise protein supply. The product was obtained in the process of microfiltration, i.e., a modern method of protein production that allows for obtaining protein of very high purity while simultaneously minimising losses of nutritional values. Unlike other methods of filtration, microfiltration does not lead to protein denaturation, which means that it retains its natural properties and structures. Thanks to this, protein obtained via this method is better absorbed by the body, which is crucial for the efficiency of recovery processes and building muscle mass.
Whey Protein Isolate (WPI) is one of the purest and most popular types of protein used in sports supplementation. It is a product obtained from whey, which is a liquid residue from the cheese production process. Whey, being a rich source of protein, undergoes multi-stage filtration, as a result of which whey protein isolate is obtained – 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 aiming to increase muscle mass, improve 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 ingredient. 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 exceptionally high Biological Value (BV), which means that it is very effectively utilised by the body. The BV of whey protein isolate is about 104, which makes it one of the highest-rated sources of protein, exceeding in this respect other popular sources, such as egg proteins (BV of 100) or plant proteins, which usually have a lower biological value.
Whey protein isolate provides a full profile of exogenous amino acids, which means it contains all essential 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 process of muscle protein synthesis, which makes WPI an ideal choice for people aiming to build and recover muscle.
Leucine, in particular, is considered the main activator of muscle protein synthesis, acting as an anabolic signal for muscle cells. Studies suggest that a 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.
