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 regulatory compounds.
Protein requirements for athletes are 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 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. They can help provide quickly absorbable protein after training, facilitate protein intake 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-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 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 dietary complement. Excessive supplement intake can limit access to other nutrients such as vitamins and minerals 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 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 workouts, 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—anywhere 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, preserving its natural properties and structure. This makes the protein more bioavailable, which is crucial for effective recovery and muscle building.
Whey Protein Isolate (WPI) 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, a rich source of protein, undergoes multi-stage filtration to obtain the whey protein isolate—a product with high protein content and low fat and carbohydrate content. These qualities have made WPI highly popular among athletes and those seeking to increase muscle mass, improve recovery, and maintain proper physique. Compared to Whey Protein Concentrate (WPC), WPI has higher protein content, making it a more concentrated source. The protein difference between WPI and WPC results from an additional filtration step that removes more fat and lactose, leaving almost exclusively protein.
Whey protein isolate has an exceptionally high biological value (BV), meaning it is very efficiently used 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 typically have lower biological values.
Whey protein isolate provides a complete profile of essential amino acids, meaning it contains all amino acids that the body cannot synthesize on its own. It is particularly 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 those 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. Research shows that the high leucine content in whey protein isolate significantly enhances anabolic processes after training, leading to faster recovery and muscle growth.
