Protein supplements are popular in the sports world, especially among active athletes, 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.
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 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 rapidly absorbable protein after training, facilitate protein intake in meals low in this nutrient, or support athletes with low appetite or in situations where access to protein-rich foods is limited.
The most popular types of protein supplements are whey protein (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 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 supplementation may limit the intake of other nutrients, such as vitamins and minerals, provided by whole food protein sources.
7Nutrition Whey Isolate 90 is an exceptional 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 individuals aiming to build muscle mass, improve post-workout recovery, 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 yields highly pure protein while minimizing nutrient loss. Unlike other filtration methods, microfiltration does not denature the protein, meaning it preserves its natural properties and structure. Proteins obtained this way are better absorbed, which is crucial for effective recovery and muscle growth.
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 byproduct of cheese production. Whey, a rich protein source, undergoes multi-stage filtration, producing a whey protein isolate – a product characterized by high protein content and low fat and carbohydrate content. These features have made WPI extremely popular among athletes and those seeking to increase muscle mass, improve recovery, and maintain an ideal physique. Compared to whey protein concentrate (WPC – Whey Protein Concentrate), the isolate has a higher protein content, making it a more concentrated protein source. The difference between WPI and WPC is due to an additional filtration step, which removes more fat and lactose, leaving almost pure protein.
Whey protein isolate has an exceptionally high Biological Value (BV), 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 protein (BV 100) or plant proteins, which usually have a 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), including leucine, isoleucine, and valine. These three amino acids play a key role in muscle protein synthesis, making WPI an ideal choice for muscle building and recovery.
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.
