7Nutrition Natural Whey Isolate 90
Protein supplements are popular in the sports world, especially among active individuals, due to the key role of protein in muscle building and recovery. Protein makes up 15-20% of human body mass and is a major 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, which allows for protein restoration 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 a proper diet, protein supplements can be useful in certain situations. Their use can help provide fast-digesting protein after workouts, facilitate protein intake 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 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 only after carefully considering their needs, goals, and training load. Protein supplements do not replace food and should be used to complement the diet. Excessive intake of supplements may limit access to other nutrients such as vitamins and minerals, which are provided by whole protein-rich foods.
7Nutrition Whey Isolate 90 is an exceptional whey protein isolate containing an impressive 90g of protein (in dry mass) per 100 g – for the natural version. Thanks to microfiltration, this product features 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 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 allows obtaining protein of very high purity while minimizing nutritional losses. Unlike other filtration methods, microfiltration does not denature the protein, preserving its natural properties and structure. This ensures that protein obtained this way is better absorbed by the body, which is crucial for the effectiveness of muscle recovery and growth 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 derived from whey, the liquid by-product of cheese production. Whey, rich in protein, undergoes multi-stage filtration to obtain 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 individuals aiming to increase muscle mass, improve recovery, and maintain physique. Compared to whey protein concentrate (WPC – Whey Protein Concentrate), the isolate contains a higher protein content, making it a more concentrated protein source. The difference in protein content between WPI and WPC results from the additional filtration step that removes more fat and lactose, leaving almost exclusively protein.
Whey protein isolate has an exceptionally high biological value (BV – Biological Value), meaning it is very efficiently utilized by the body. The BV of whey protein isolate is about 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 values.
Whey protein isolate provides a complete profile of essential amino acids, meaning it contains all amino acids the body cannot produce on its own. It is particularly rich in branched-chain amino acids (BCAAs – Leucine, Isoleucine, Valine), which play a key role in muscle protein synthesis, making WPI ideal for those aiming for muscle growth 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 post-workout, leading to faster recovery and muscle growth.
