Protein supplements are popular in the sports world, especially among active individuals, due to the crucial role of protein in muscle building and recovery. Protein makes up 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 allows for protein rebuilding after training. For athletes aiming to reduce body fat while maintaining muscle mass, recommendations can increase to 1.6-2.4 g/kg. It is also important to distribute protein intake throughout the day, with a recommended 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 proteins post-workout, supplement meals low in protein, or support athletes with low appetite or in situations 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., pea, hemp, rice). Whey proteins are highly valuable animal-based proteins, rich in branched-chain amino acids, particularly leucine, which plays a key role in anabolic processes.
It is important for athletes to consider protein supplementation carefully based on their needs, goals, and training load. Protein supplements do not replace food and should be used as a dietary supplement. Excessive supplementation may limit access to other nutrients, such as vitamins and minerals, which are provided by whole food protein sources.
7Nutrition Whey Isolate 90 is a unique whey protein isolate containing an impressive 90g of protein (dry matter) per 100 g – for the natural flavor. Thanks to microfiltration, this product has an excellent amino acid profile and very low fat and carbohydrate content. This formula makes it ideal for those aiming to build muscle mass, improve post-workout recovery, and maintain energy levels throughout the day. The isolate is also easy to dissolve, 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 yields very high-purity protein while minimizing nutrient loss. Unlike other filtration methods, microfiltration does not denature the protein, preserving 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 building.
Whey protein isolate (WPI – Whey Protein Isolate) is one of the purest and most popular types of protein used in sports supplementation. It is derived from whey, the liquid remaining after cheese production. Whey, rich in protein, undergoes multi-stage filtration to produce whey protein isolate – a product characterized by high protein content and low fat and carbohydrate levels. These features make WPI extremely popular among athletes and those aiming to increase muscle mass, improve recovery, and maintain a fit body. Compared to whey protein concentrate (WPC), the isolate has a higher protein content, making it a more concentrated source. The difference in protein content between WPI and WPC results from an additional filtration step that removes more fat and lactose, leaving almost pure protein.
Whey protein isolate has an exceptionally high biological value (BV – Biological Value), meaning it is very efficiently used by the body. The BV of whey protein isolate is around 104, making it one of the highest-rated protein sources, surpassing other popular sources such as egg protein (BV 100) or plant proteins, which usually have lower biological value.
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 especially rich in branched-chain amino acids (BCAAs), including leucine, isoleucine, and valine. These three amino acids play a key role in muscle protein synthesis, making WPI an ideal choice for building and recovering muscles.
Leucine, in particular, is considered the main 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 post-workout, leading to faster recovery and muscle growth.
