Uses: The need for protein in the human diet has been increasingly studied, especially in the last decade. As a result of this research, several factors regarding the optimal daily requirements and sources of protein have become very clear. Even the current government published RDIs, which are based solely on minimal needs for survival, have increased to .6-.8 grams per kilogram of body weight per day.
Current clinical findings however indicate that an RDI necessary to maintain optimum health for even a sedentary adult are closer to double that. Circumstances including illness, fat-loss diets, regular exercise, accelerated adolescent growth, or chronic mental or emotional stress indicate requirements 2-3 times that. Competitive or strength athletes, post surgical patients or any situation causing wasting disease such as chemotherapy, HIV, burn trauma or radiation therapy can increase the metabolic need for protein by a factor of up to 6 times the official government RDIs.
Furthermore, these figures represent protein which has been absorbed and made available to the tissues of the body and not merely that which has been consumed. This is a distinction current clinical research has recognized as critical to proper understanding of the need for protein in the human diet.
Before protein can be absorbed and utilized it must first be digested. Following digestion the free amino acids and di and tripeptides that result from protein breakdown are absorbed at the surface of the small intestine. The process of digestion and absorption requires several steps and is most efficient in the upper portion or proximal section of the jejunum (small intestine). In order for absorption of dietary protein to occur, it must first be reduced from larger oligo and polypeptides to di and tripeptides, the smallest protein fragments consisting of only two or three peptide-bonded amino acids, and free amino acids. Di and tripeptides have been clearly shown to be preferential over free forms. This process must occur fast enough and at a rate high enough to take advantage of the proximal transporters, those that specialize in di and tripeptides and which are in abundance only in this short section of upper intestinal bowel. Once protein has passed this lumenal area, relatively no further protein breakdown or absorption occurs. The balance moves on relatively unchanged into the colon, where it is definitely a negative health factor causing minimal gas and gastrointestinal distress, and when experienced chronically, can lead to colon disease and malignancy. It is now generally believed to be the number one factor responsible for the world's highest rate of colon cancer experienced in the U.S.
Pro-Xtreme is specifically engineered based on a new profile for protein in optimum human metabolism arising from these new clinical findings. With an exceptionally high di and tripeptide content of 40 percent, Pro-Xtreme not only promotes increased nitrogen retention--thereby minimizing the negative effects of increased protein intake or reduced caloric intake--but it works in harmony with natural gastrointestinal activity to produce maximum absorption as well.
Because of the fat content and the density of the bolus, meals containing tissue-source protein are released from the stomach and travel through the intestines at a rate which is naturally slower and more conducive to efficient digestion and absorption. The problems begin when too much tissue protein is consumed or the process of digestion and absorption is incomplete. It is estimated that at best only 30-35% of the protein consumed in an average protein-containing meal is absorbed allowing the balance of now detrimental undigested protein to pass into the colon.
In the case of liquid protein supplements, the problem is one not only of excessive amounts of protein being consumed but also the speed at which the bolus travels throughout the jejunum. Liquid meals, especially those with insufficient soluble fiber, have decreased transit time, leaving less time for digestion and absorption. Consequently, even in individuals with normal gastrointestinal function, liquid forms of whole proteins generally result in equally incomplete and oftentimes less absorption than their tissue food counterparts.
Pro-Xtreme utilizes sequentially hydrolyzed whey protein isolates of the highest quality to insure complete and rapid absorption of the highest levels of essential and branched-chain amino acids (BCAAs) in the preferred smallest peptide bonded form. These features, coupled with its industry-leading lowest average molecular weight, soluble-fiber content and delicious vanilla-cappuccino flavor, offer a primary source of protein that may be used any time a protein supplement is desired.
The combination and sequencing of amino acids in whey protein also results in increased tissue storage of glutathione, a stable tripeptide whose antioxidant activity is known to improve immune function. And, although whey protein naturally contains 5 to 7 percent of glutamine, the formula for Pro-Xtreme incorporates additional gram amounts of L-glutamine to its list of highly evolved ingredients as well. This extra step is designed to promote anticatabolic effects in skeletal muscle while focusing on gastrointestinal and immune function improvement. Glutamine and the critical BCAA leucine are deemed indispensable for the healthy functioning of other tissues and metabolic processes. By maintaining a rich supply of BCAAs, Pro-Xtreme proves protein sparing within muscle and offers the highest biological value possible.
