Protein supplements are popular in the sports world, especially among actively training individuals, due to the key role of protein in building and muscle 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.
Athletes' protein requirements are higher than those of 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 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 an appropriate diet, protein supplements can be useful in certain situations. Their use can help provide fast-absorbing protein after training, supplement protein in meals with low protein content, or support athletes with low appetite or in conditions 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 proteins (e.g., pea, hemp, rice). Whey proteins are highly valuable animal-derived proteins, rich in branched-chain amino acids, especially leucine, which plays a key role in anabolic processes.
It is important for athletes to 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 complement. Excessive intake of supplements can limit access to other nutrients, such as vitamins and minerals, which are provided by whole protein foods.
7Nutrition Whey Isolate 90 is a unique whey protein isolate, containing an impressive 90g of protein (dry weight) 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 individuals aiming to build muscle mass, improve post-training recovery, and maintain adequate energy levels throughout the day. The isolate is also easy to dissolve, 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 achieves highly pure 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 obtained from whey, the liquid byproduct of cheese production. Whey, being a rich source of protein, undergoes multi-stage filtration, resulting in whey protein isolate – a product characterized by high protein content and low fat and carbohydrate levels. These features have made WPI extremely popular among athletes and those aiming to increase muscle mass, improve recovery, and maintain proper body composition. Compared to whey protein concentrate (WPC – Whey Protein Concentrate), the isolate has a higher protein content, making it a more concentrated source of this nutrient. The difference in protein content between WPI and WPC is due to an additional filtration stage, which removes more fat and lactose, leaving almost pure protein.
Whey protein isolate is characterized by 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 generally have lower biological value.
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 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 after training, leading to faster recovery and muscle growth.
