Protein supplements are popular in the sports world, especially among actively training individuals, due to the key role of protein 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.
The protein requirement for athletes is higher than for sedentary individuals, ranging from 1.2 to 1.6 g/kg of body weight per day, allowing for protein reconstruction 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 0.3-0.4 g/kg per meal or snack, corresponding to 15-30 g of protein per serving.
Although most athletes can meet their protein needs through a proper diet, protein supplements can be useful in certain situations. Their use can help provide fast-absorbing protein post-workout, support protein intake in meals low in protein, or assist athletes with low appetite or in situations where access to protein-rich foods 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 high-quality animal-derived proteins rich in branched-chain amino acids, particularly leucine, which plays a key role in anabolic processes.
It is important for athletes to decide on protein supplementation only after carefully considering their needs, goals, and training load. Protein supplements do not replace food and should be used as a dietary complement. Excessive intake of supplements may limit access to other nutrients, such as vitamins and minerals, which are provided by whole protein-rich foods.
7Nutrition Whey Isolate 90 is a unique whey protein isolate, containing an impressive 90g of protein (dry mass) per 100 g – for the natural version. 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 recovery after training, and maintain proper 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 ensures very high protein purity while minimizing nutrient loss. Unlike other filtration methods, microfiltration does not denature the protein, meaning it retains its natural properties and structures. Consequently, protein obtained this way is better absorbed by the body, which is crucial for effective recovery and muscle-building processes.
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 by-product of cheese production. Whey, a rich protein source, undergoes multi-stage filtration to obtain whey protein isolate – a product characterized by high protein content and low fat and carbohydrate content. Due to these properties, WPI has become extremely popular among athletes and those aiming to increase muscle mass, improve recovery, and maintain an optimal physique. Compared to whey protein concentrate (WPC – Whey Protein Concentrate), 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 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 around 104, making it one of the highest-rated protein sources, surpassing other popular sources such as egg proteins (BV of 100) or plant proteins, which generally have lower biological value.
Whey protein isolate provides a complete profile of essential amino acids, meaning it contains all amino acids the body cannot synthesize. It is particularly rich in branched-chain amino acids (BCAAs – 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 recover muscles.
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 post-training, leading to faster recovery and muscle growth.
