Whey Protein Powder Isolate (benefits/ingredients) by Life Extension Foundation In recent years, scientists have begun to investigate the ability of certain proteins to improve health.  Years of scientific research have resulted in the development of a specially designed whey protein that considerable evidence now shows produces multiple health benefits. These benefits include: Helping to protect against free radicals while boosting cellular glutathione levels, Extending life span in laboratory animals, Enhancing immune function. Athletes were the first to use whey protein as an anti-catabolic supplement to build lean muscle mass, however, scientific studies have shown a wide array of health benefits. Life Extension uses a production method that produces a whey protein isolate that provides even better health maintenance than previous products. Using a low temperature microfiltration technique, it is possible to produce a 98% undenatured whey protein isolate that acts as a powerful immune stimulant and retains all the important subfractions, such as lactoferrin, a strong antioxidant with immune properties.  Enhanced Life Extension Protein is a third generation whey protein containing 4 times as much lactoferrin as most other whey protein supplements on the market, and is, to our knowledge, the only such whey protein supplement that contains added lactoferrin.  Lactoferrin appears to be a subfraction of whey with the best documented and immune enhancing effects.  When we talk about whey, we are actually referring to a complex protein made up of many smaller protein subfractions (peptides).  Many of these subfractions are only found in very minute amounts in cows milk, normally at less than 1%.  For example, lactoferrin makes up only 0.5% to 1% or less of whey protein derived from cows milk.  Mothers milk, on the other hand, will contain up to 15% lactoferrin. Lactoferrin is found throughout the human body and occurs in all secretions that bathe mucous membranes such as saliva, tears, bronchial and nasal secretions, hepatic bile, pancreatic fluids, and is an essential factor in the immune response.  Lactoferrin is concentrated in oral cavities where it will come in direct contact with pathogens (i.e. viruses, bacteria, etc.) greatly suppressing these pathogens through a variety of different mechanisms.  In fact, there are specific receptors for lactoferrin found on many key immune cells, such as lymphocytes, monocytes and macrophages, and is known to be directly involved in the upregulation of natural killer (NK) cell activity.  One study with baby pigs found that only 17% of the pigs died when fed lactoferrin and injected with a toxin (escherichia coli) as opposed to 74% of the pigs that died without the lactoferrin. Gastrointestinal Function Lactoferrin appears to be particularly important in the health and function of the intestinal tract.  It has been found to greatly reduce systemic and intestinal inflammation in such conditions as inflammatory bowel disease, among others.  Animals subjected to a variety of pathogens known to cause both systemic and intestinal inflammation and damage show much greater resistance and reduced inflammation when fed lactoferrin. Iron Effects Lactoferrin is probably best known for its role as an iron binding protein.  It's referred to as holo-lactoferrin in its iron bound form and apo-lactoferrin in its iron depleted form. Lactoferrin is a powerful agent able to inhibit a wide range of pathogenic bacteria and other microbes.  The mechanism appears to lie with lactoferrin's ability to bind with iron, as it is known to have an extremely high affinity for this metal.  Many pathogenic bacteria need a supply of free iron to multiply and in the presence of lactoferrin are strongly inhibited. Lactoferrin as an Antioxidant Finally, lactoferrin is an antioxidant that scavenges free-iron helping to prevent uncontrolled iron-based free radical reactions, thus protecting certain cells from peroxidation.  Though lactoferrin is both an iron scavenger and donor (depending on the cellular environment), it has been found to scavenge or donate iron at the appropriate times when the body is in need of the reaction.  At normal physiological PH, lactoferrin binds iron tightly thus diminishing oxidative stress to tissues (from free radical production of iron).  Apolactoferrin, but not hololactoferrin, has been shown to prevent lipid peroxidation.
