7Nutrition Natural Whey Isolate 90 is a professional whey protein isolate (WPI), created for athletes and active individuals looking for a pure source of high-quality protein. The formula is based exclusively on raw material obtained through advanced microfiltration, ensuring maximum concentration of amino acids with milk sugar and fat content reduced to a minimum.
Protein supplements are popular in the world of sport, especially among those training actively, due to the key role of protein in building and repairing muscles. Protein accounts for 15-20% of the human body weight 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.
Key information about 7Nutrition Natural Whey Isolate 90
- As much as 87 g of protein per 100 g (in dry matter).
- Pure composition (100% WPI) without unnecessary additives, sweeteners, flavourings, or fillers.
- High biological value (BV 104) – optimal absorption and efficient metabolic utilisation by the body.
- Rich amino acid profile – high concentration of essential amino acids, including BCAA complex and L-leucine.
- Advanced microfiltration ensuring excellent raw material purity without denaturation of protein structures.
- Versatility of use – ideal for shakes, oatmeal, omelettes, and home-made high-protein bakes.
- Natural raw material variation – organoleptic properties (taste, smell, shade, or consistency) may vary depending on the production batch; this results from the natural variation of the base raw material.
The role of high-quality protein in an athlete's diet
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, which allows for protein repair 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 to consume 0.3-0.4 g/kg per meal or snack, which corresponds to 15-30 g of protein per serving size.
Although most athletes may meet their protein requirements through a proper diet, protein supplements can be useful in certain situations. Their use may help in providing rapidly absorbed proteins after training, facilitate replenishing protein in meals with a low content of this ingredient, or support athletes with a poor appetite or in conditions where access to protein-rich food is limited.
Different sources of protein in the diet
The most popular types of protein supplements are whey proteins (WPC, WPI, WPH), casein, soy protein, and plant-based protein (e.g., from pea, hemp, rice). Whey proteins are high-quality proteins of animal origin, rich in branched-chain amino acids, especially leucine, which plays a key role in anabolic processes.
It is important that athletes decide on protein supplementation after careful consideration of their needs, goals, and training load. Protein supplements do not replace food and should be used as a supplement to the diet. Excessive consumption of supplements may limit access to other nutrients, such as vitamins and minerals, which are provided by high-quality protein products.
As much as 87 g of protein and microfiltration without denaturation
7Nutrition Whey Isolate 90 is a unique whey protein isolate that contains an impressive 87 g of protein (in dry matter) per 100 g – for the natural version. Thanks to the microfiltration used, this product is characterised by an excellent amino acid profile and a very low content of fat and carbohydrates. Such a formula makes it ideal for people aiming to build muscle mass, improve recovery after training, and maintain an appropriate energy level throughout the day. The isolate is also easy to mix, which makes it a convenient addition to cocktails, smoothies, or oatmeal, i.e., wherever you need to optimise protein supply.
The product was obtained in the process of microfiltration, a modern method of protein production that allows for obtaining protein of very high purity while minimising the loss of nutritional value. Unlike other filtration methods, microfiltration does not lead to protein denaturation, which means that it retains its natural properties and structures. As a result, protein obtained by this method is better absorbed by the body, which is crucial for the efficiency of recovery processes and muscle mass building.
What is whey protein isolate?
Whey protein isolate (WPI – Whey Protein Isolate) is one of the purest and most popular types of protein used in sports supplementation. It is a product obtained from whey, which is the liquid residue after the cheese production process. Whey, being a rich source of protein, is subjected to multi-stage filtration, resulting in whey protein isolate – a product characterised by high protein content and low fat and carbohydrate content. Due to these features, WPI has gained huge popularity among athletes and people aiming to increase muscle mass, improve recovery, and maintain a proper physique.
Compared to whey protein concentrate (WPC – Whey Protein Concentrate), the isolate is characterised by a higher protein content, which makes it a more concentrated source of this ingredient. The difference in protein content between WPI and WPC results from an additional filtration step, which removes a larger amount of fat and lactose, leaving almost exclusively protein.
Biological value BV 104 and BCAA amino acid profile
Whey protein isolate is characterised by an exceptionally high biological value (BV – Biological Value), which means that it is very efficiently used by the body. The BV of whey protein isolate is approximately 104, which makes it one of the highest-rated sources of protein, exceeding in this respect other popular sources such as egg proteins (BV of 100) or plant-based proteins, which usually have a lower biological value.
Whey protein isolate provides a full profile of essential amino acids, which means it contains all the necessary 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 the muscle protein synthesis process, which makes WPI an ideal choice for people aiming to build and repair muscles.
Leucine, in particular, is considered the main activator of muscle protein synthesis, acting as an anabolic signal for muscle cells. Studies suggest that a high leucine content in whey protein isolate contributes to a significant intensification of anabolic processes after training, which leads to faster recovery and muscle growth.
