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 makes up 15-20% of the 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 requirements for athletes are higher than for 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 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, 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, aid in supplementing protein in low-protein meals, 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-derived 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 dietary complement. Excessive supplement intake may 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 mass) 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 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 allows obtaining highly pure protein while minimizing nutrient losses. Unlike other filtration methods, microfiltration does not denature the protein, preserving its natural properties and structure. Proteins obtained this way are 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 protein source, undergoes multi-step filtration, resulting in whey protein isolate – a product characterized by high protein content and low fat and carbohydrate content. Thanks to these features, 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), the isolate has a 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 has an exceptionally high biological value (BV – Biological Value), meaning it is 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 usually have a 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 – 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 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 high leucine content in whey protein isolate significantly enhances anabolic processes post-workout, leading to faster recovery and muscle growth.
