Undenatured Whey Protein

What is undenatured whey protein? Can I buy it in a health food store? What does it do, and why should I use it? Let's start first with whey protein in general. This is the protein that has been isolated from whey. Whey is the liquid material that is left behind after the solids have been removed from cow's milk. Manufacturers have processed this protein into mixtures that can be used for building muscle or for muscle building and muscle development. You can find a large array of whey protein powder to make a breakfast smoothie, or protein drink, at any general nutrition, weight training, or bodybuilding supplements store or supplier. Muscle Milk and Designer Whey are popular examples of this today for a breakfast smoothie, protein shake, or protein drinks.

It is also a good choice for anyone who would like to reduce their body fat, and build muscle through exercise and/or bodybuilding supplements. But all protein supplements are not created equal. This type of protein is classified as denatured. What does denatured mean? This simply means that the whey protein has been processed at a high temperature, usually above 160 degrees Fahrenheit or 72 degrees Celsius. This process is also known as pasteurization. The milk you buy in the store has been pasteurized, which means that it has been denatured or cooked at a high temperature to ensure that all microorganisms that may harm you have been destroyed.

So to put it all together, what is undenatured whey protein? It is protein from whey that has not been denatured. This means that the protein must be processed in such a way that harmful organisms are destroyed, but the heat sensitive amino acids that make it bioactive, called branched chain amino acids, are not harmed. It has not been pasteurized, but processed at a lower temperature in order to preserve the amino acids that are destroyed by high heat. Terms that can be used interchangeably for undenatured whey protein are high biological value whey protein and bioactive whey protein. You may also hear it referred to as undenatured whey protein isolate, or undenatured whey protein concentrate.

This kind of whey protein from raw cow's milk has a very high amount of bonded cysteine in it, along with other essential branched chain amino acids, so is has a high biological value, with one particular brand having a biological value of >110 BV. As more people find out about the value of high biological value whey protein, a manufacturer may suggest on the label of their product that they are providing such a special protein. Truly bioactive whey protein is quite expensive to make and requires special technology to do so. Another way that you can tell it is not bioactive is if it is flavored. If it comes in vanilla, chocolate, or strawberry, then it has been hydrolyzed, which means it has been denatured to make it easier to mix. This is not bioactive whey protein, and will not help you in raising glutathione. Undenatured whey protein has a very unmistakable quality to it: it is unflavored and very difficult to mix. If you pour some bioactive whey protein powder into a liquid, it will float and resist mixing. This is one way to know you have truly undenatured whey protein. Undenatured whey protein will help you to build muscle just like regular whey protein. The main reason you want to take it in an undenatured form is if you want to raise glutathione in addition to building muscle. Undenatured whey protein will build muscle AND raise glutathione!

Bioactive whey protein contains three specific proteins that are very high in an amino acids that is missing from our diet today. The proteins are: albumin or bovine serum albumin, lactoferrin, and lactalbumin. These proteins are very high in the amino acid called bonded cysteine. It is found in raw meat, raw eggs, and raw cow's milk. Once you cook these three foods, the bonded cysteine or cystine is destroyed by heat.

Most of us today do not consume these foods raw, nor do we recommend that you do. Babies who are breast-fed have access to bonded cysteine in their mother's breast milk until they are weaned. The closest food that we have to mother's breast milk as adults is bovine or cow milk in raw form. Now that we don't have access to these foods in safe amounts, we have an even greater need than ever before to find a good source of bonded cysteine so that we can effectively raise glutathione.

Glycine and glutamate are plentiful in our diet, but cysteine is not. Thus, bonded cysteine is considered the rate limiting factor for raising glutathione in our cells. The journey of a bonded cysteine molecule from the mother's breast or cow's udder to your cells to make glutathione is a fascinating journey. Very simply, bioactive whey protein is the best way for raising glutathione because it is the way that you were created to raise it once you are weaned.
