Whey Protein long has been advocated by bodybuilders because of its ability to promote muscle growth. In recent years, however, research has mounted that the benefits of Whey Protein may be far more reaching than previously thought. Indeed, Whey Protein may offer important health benefits to people of every age and any physical condition. This is because current data indicates that Whey Protein may provide significant immune system support, antioxidant activity, and enhanced intestinal lining integrity.

Jarrow Formulas® Whey Protein is quality – it is as good a source of Whey Protein as you can buy. It is meticulously processed to retain whey’s full complement of antioxidant and immuno-stimulatory properties. To provide such high quality, Jarrow Formulas® Whey Protein is ultrafiltered under low heat and is non-hydrolyzed.

What is Whey?

Whey Protein is the soluble component of milk protein; the insoluble portion is casein. Whey is derived from cheese manufacturing. Cow’s milk whey is comprised of several different types of soluble proteins, primarily beta-lactalglobulin, alpha-lactalbumin, immunoglobulin, and albumin.

Whey was initially considered to be a waste product, whereas now it’s considered to be a functional food with remarkable applications ranging from protein supplementation to immune support. Jarrow Formulas® Whey Protein provides a better Whey Protein which retains all the benefits of its natural source while eliminating any undesirable components. For instance, it is very low in lactose and therefore safe for lactoseintolerant individuals. No other Whey Protein delivers more benefits than Jarrow Formulas® Whey Protein.

The Better Whey for Exercise & Increased Protein Requirements

Numerous studies point to the need for protein supplementation to stabilize nitrogen balance during exercise in general, and resistance training in particular. Whey is possibly the most biologically active protein (see graph).

Exercise physiologists now recommend approximately 2.0 grams of protein per kilogram of body weight per day, a figure which exceeds the current RDI for adults. Increased protein consumption helps to counteract the accelerated metabolism of amino acids which exercise causes, and therefore helps to prevent muscle breakdown. Jarrow Formulas® Whey Protein is a preferred supplement to ensure adequate protein for all physical activity. It is very low in carbohydrates and fat.

The Better Whey for Muscle Mass

Whey Protein is a rich source of glutamine, a major constituent of skeletal muscle cells. Jarrow Formulas® Whey Protein is non-hydrolyzed and carefully processed at low temperatures to concentrate and preserve the original glutamine content. Glutamine stimulates protein synthesis. Maintaining an adequate supply in the body therefore is critical for muscle tissue repair and growth. Weight-bearing exercise, physiological stress, and other factors damage muscle cells and deplete muscle tissue of glutamine, leading to a breakdown of muscle tissue if glutamine stores are not continually replenished.

Compared to other protein sources, non-hydrolyzed Whey Protein also features one of the highest levels of Branched-Chain Amino Acids (BCAAs). BCAAs (leucine, isoleucine, and valine) are metabolized (oxidized) in skeletal muscle as an energy source and they serve to maintain nitrogen balance. They are helpful for maximizing muscle performance. As the chemical precursors or building blocks of the amino acid glutamine, BCAAs discourage muscle breakdown during exercise and other times of physiological stress. Studies suggest that taking BCAAs prior to exercise may affect the body’s responses to some anabolic hormones, particularly growth hormone, insulin, and testosterone. These altered responses support muscle protein synthesis. Jarrow Formulas® Whey Protein provides the richest concentration of BCAA’s found in nature.

The Better Whey for Immune Function and Antioxidant Status

A substantial portion of Jarrow Formulas® Whey Protein is comprised of immunoglobulins. These immunity-boosting proteins act as antibodies and attack foreign substances which enter the body.

Whey Protein is a significant source of the amino acid cysteine, which the body requires for the production of glutathione. Glutathione is a powerful antioxidant that protects and detoxifies cells from harmful chemicals and heavy metals. In addition to protecting healthy cells, studies have demonstrated that Whey Protein may selectively deplete glutathione from cells exhibiting abnormal growth, thereby weakening these cells. (Baruchel S, Viau G. In vitro selective modulation of cellular glutathione by a humanized native milk protein isolate in normal cells and rat mammary carcinoma model. Anticancer Res. 1996 May-June;1095-9.)

The high glutamine content of Jarrow Formulas® Whey Protein benefits the immune system. Glutamine accelerates the production of metabolic compounds which support immune function, and it is an important fuel source for lymphocytes and macrophages (which target and destroy foreign substances in the body).

Non-hydrolyzed Whey Protein contains active antioxidants which appear to prevent oxidation of low density lipoproteins (LDL) within the vascular system, a major trigger of arterial plaque formation.

The Better Whey For Intestinal Health

As a rich source of glutamine as well as a source of whey protein growth factors, Jarrow Formulas® Whey Protein may significantly enhance intestinal health. Whey Protein contains growth factors which, according to initial research findings, may support the health of the intestinal lining. Whey Protein is rich in biologically active proteins called glycomacropeptides. These peptides improve digestion and nutrient absorption, and they support the growth of beneficial bifidobacteria in the large intestine.

Glutamine complements the actions of the glycomacropeptides. This amino acid has been clinically documented to promote healing of the intestinal lining and to improve nutrient absorption by damaged villi (the tiny finger-like absorptive sites in the intestine).

Usage

One scoop (26 grams) supplies 18 grams protein. Available in unflavored, vanilla creme and chocolate. Contains no artificial flavors or sweeteners.
