Soy Protein Isolate Powder supplies important nutrients which the body requires daily for optimum health. It provides essential amino acids in a versatile powder which is low in fat and free of carbohydrates. It is also a superior protein source for vegetarians. The production and development of soy protein changed dramatically over the following decade with the introduction of isolation. Isolation is a method of extracting the soy protein from the beans and concentrating it to make it far more useful to the body than the old soy concentrate. This new product is called soy protein isolate and contained over 90% protein
Soy protein isolate is a niche bodybuilding supplement that, in some cases, offers special advantages that can’t be gained from other types of supplements. We explore those benefits here.
For years, bodybuilding gurus have recommended the use of soy protein for pre-contest bodybuilders who need to shed body fat while keeping as much lean muscle as possible. Normally when the body is forced into a low calorie diet program, it reacts by slowing down your metabolic rate. This will make it increasingly more difficult to lose body fat. Soy-protein isolate helps lessen this effect through several different pathways. First, soy-protein isolate has been found to enhance endogenous production of thyroid stimulating hormone (TSH), thyroxin (T4), and tri-iodothyronine (T3). Thyroxin is the main player in the regulation of your metabolic rate. The more thyroxin you have the faster your metabolism will be. A faster metabolism insures that more of the food you eat will be used as fuel and less will be stored as fat, an important advantage to any dieter.
Of particular interest to the bodybuilder is Soy Isolates high concentration of the amino acids glutamine and arginine. These two aminos are extremely important to a body builder for their ability to release growth hormone, aid in immune system functions, and for their ability to speed muscle cell recovery. Research also indicates that the soy-protein isolates may reduce nitrogen loss and keep you in a positive nitrogen balance to better facilitate muscle growth. The human body can only repair and build muscles when it has a positive nitrogen balance.
