Protein is probably the most important supplement for all athletes, but it is especially indispensable for those involved in long-term, high intensity endurance training. It is the fuel for the build-up, mass and toning of the muscle. In fact, protein is essential for growth and development. The proteins that make up the human body are not obtained directly from the diet; rather, dietary protein is broken down into its constituent parts known as amino acids, which are the basic building blocks of life. That means that it is the amino acids, and not protein per se, which are essential nutrients.
Of the 20 amino acids that the body needs to make protein, eleven are designated as nonessential amino acids, because they can be produced by the human body from other amino acids and do not need to be obtained from the diet. The remaining nine amino acids cannot be synthesized by the body and are, therefore, called essential amino acids. These amino acids must be obtained by degradation of the dietary protein. All of these essential amino acids must be present in the body in order for it to build and repair muscle.
The manner in which the body uses protein during and after exercise is quite different from the way it utilizes carbohydrates or fat for energy. In the hours after exercise, the body begins to build the so-called structural proteins from amino acids for muscle repair and growth, and remodeling the tissues needed for performance. This is one of the reasons that athletes should pay particular heed to nutrition for complete recovery fast and make it an integral part of their workout regimen.
Exercise duration and intensity are important factors in determining which of the nutrient fuels are burned to gain energy. An exercise regimen comprising of low- to moderate intensity of long duration necessitates large quantities of fuel --oftentimes more than carbohydrates and fat reserves in the body can provide. Therefore, the body begins to utilize structural and functional proteins during long-term aerobic exercise. In contrast, high-intensity exercise of short duration mostly uses glucose, which spares the protein reservoir of the body.
To meet the needs of athletes, Whey protein all the essential and nonessential amino acids to build the muscle after intense exercise of both short and long duration. It is a customized blend of all the nutrients, including immune enhancing factors from whey protein by a specialized process. Since exercise can take a toll on the immune system, Whey protein is the nutritional supplement of choice for those who lead an active lifestyle. Whey protein is not just for the athlete however. It supports the msucle maintenance, buildup and toning among individuals who are merely "weekend warriors." Furthermore, it provides wholesome support for compromised or wasting muscle due to advancing years. Ultimate Nutrition's Whey protein is, indeed, the nutrition for the champions!

FREQUENTLY ASKED QUESTIONS
1) How is Whey protein Taken?
It can be ingested in many different ways. Most commonly, it is either mixed with water or a nutritious beverage. It can be taken numerous times during the day to boost energy, but it is most beneficial if taken immediately after intense exercise. Two or three servings daily are recommended for those involved in vigorous exercise to ensure maintenance of positive nitrogen balance. This allows the body to repair and build muscle and minimize muscle breakdown.
2) How Does Whey protein Boost Immunity?
Whey protein is quite singular in its property to boost immunity by increasing the body's own antioxidants. In addition, Whey protein is blended such that the immune boosting proteins are retained, which include b-globulin, a-lactalbumin, glycomacropeptide, immunoglobulins and, among others, lactoferrin. All constituents in this category inherently boost the immune system, which does become weakened somewhat with sustained exercise regimens.
3) How Does Whey protein Taste?
Prostar Whey has been blended with natural strawberry and vanilla flavors to overcome the chemical taste that the amino acids normally tend to have. Importantly, its taste is the result of a complex low-temperature that utilizes proprietary refinements to capture the beneficial principles in whey.
4) Does Whey protein Induce Growth Hormone?
Insulin growth factor-1 (IGF-1) is the hormone released during growth hormone metabolism. The amount of IGF-1 produced is determines the extent of growth hormone on growth in general. Studies have shown that IGF-1 rises in direct proportion to the quantity and quality of protein in the diet. Hydrolyzing whey increases its biological value that, in turn, increases the release of IGF-1 making whey the best body-building protein available by far.
