WPI is the name of a type of "whey protein isolate" protein, which is based on milk proteins derived from whey. Isolates are the most technologically advanced protein nutrients derived from milk. Whey protein isolate is produced by cross-flow microfiltration. This advanced process, carried out at low temperatures, ensures that valuable and bioactive components are not broken down. The absorption rate of isolates is significantly higher than other forms of protein nutrients. They are considered the best and most rapidly absorbed whey proteins. This is due to their very low carbohydrate and fat content.
The composition of whey protein isolate is approximately 85-90% concentrated protein, 0-3% carbohydrates, and 1-3% fat. Unlike other protein supplements, isolate is absorbed much faster by our body and has a very short absorption period of up to 60 minutes. Isolate is a nutrient dedicated not only to those who want to build muscle mass, but also to those who want to reduce excess weight, as the higher amount of protein consumed in the diet accelerates the metabolism.
It is important to remember that protein is an essential element for building and maintaining muscle mass and is one of the key points of a healthy diet. Throughout the day, it can be an ideal way to supplement protein deficiencies in the diet.
Isolates are also distinguished by their higher content of BCAA amino acids. Thanks to the rapid absorption of essential amino acids, the body replenishes its deficiencies with an anti-catabolic effect. This makes it ideal as a post-workout supplement. Isolate also has a regenerative effect. Not only does it supplement our diet, but it also provides the highest quality protein and amino acid compounds we need for regeneration. Protein isolate is one of the valuable forms of protein supplements, has a positive effect on the immune system and improves the body's resistance.
Protein isolates from whey are characterized by excellent solubility and exceptional lightness. There are also "lactose-free" whey proteins for those who are lactose intolerant.
The optimal amount of protein in the diet is approximately 1.5-2.6 g/kg of body weight to maintain optimal physique and body quality. This represents approximately 35% of the daily calorie requirement. During a period of weight loss, aim for the upper limit, as protein helps reduce fat and speeds up metabolism, which promotes weight loss.
The use of protein supplements is closely linked to the trainee's diet. They supplement the amount of protein in the diet. Protein supplements allow for fairly accurate regulation of the proportion of daily protein intake in the diet, both in building muscle mass and reducing adipose tissue. In the case of increased physical exertion, whey protein isolate, combined with a complex of vitamins and minerals, ensures the proper functioning of metabolic processes.
