Protein supplements are popular in the sports world, especially among active individuals, due to the key role of protein in building and recovering muscles. 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 rebuilding after training. For athletes aiming to reduce body fat while maintaining muscle mass, recommendations may rise 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, which corresponds 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. They can help provide quickly absorbable protein after training, supplement meals low in protein, or support athletes with low appetite or limited access to protein-rich foods.
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 proteins rich in branched-chain amino acids, particularly leucine, which plays a key role in anabolic processes.
It is important for athletes to choose protein supplementation after carefully considering their needs, goals, and training load. Protein supplements do not replace food and should be used as a diet complement. Excessive intake of supplements may limit access to other nutrients, such as vitamins and minerals, provided by whole-food protein sources.
7Nutrition Whey Isolate 90 is a premium whey protein isolate that contains an impressive 90g of protein (dry weight) per 100g – 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-workout recovery, and maintain proper energy levels throughout the day. The isolate is also easy to mix, making it convenient for 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 purity 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 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 obtained from whey, a liquid by-product of cheese production. Whey, a rich protein source, undergoes multi-stage filtration, resulting in whey protein isolate – a product characterized by high protein content and low fat and carbohydrate content. Thanks to these qualities, WPI has gained great popularity among athletes and individuals seeking muscle growth, improved recovery, and maintenance of a lean physique. Compared to whey protein concentrate (WPC – Whey Protein Concentrate), the isolate contains higher protein content, making it a more concentrated source. The difference in protein content between WPI and WPC comes from an additional filtration step that 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 utilized by the body. The BV of whey protein isolate is approximately 104, making it one of the highest-rated protein sources, surpassing other popular sources such as egg proteins (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 the amino acids the body cannot produce on its own. 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 main activator of muscle protein synthesis, acting as an anabolic signal for muscle cells. Studies show that the high leucine content in whey protein isolate significantly enhances anabolic processes after training, leading to faster recovery and muscle growth.
