:
- Immunoglobulins,
- Lactoferrin
- Both of these have been shown in studies to improve gastrointestinal function & immune system strength. All other whey proteins currently on the market are high heat processed which destroys their natural essential biological activity.
- Unlike many proteins shakes that use soy, Whey Healthier uses whey protein - nature's richest source of biologically active protein. Soy protein is low in the amino acid methionine, but whey protein contains all the amino acids your body needs in the best balance yet found in any food.
- The organic and low heat processed whey protein comes strictly from herds that graze on pesticide-free, chemical-free natural grass pastures.
- These are not from factory farms that feed the cows grains, which transforms healthy milk proteins into allergens and carcinogens begins with modern feeding methods that substitute high-protein, soy-based feeds for fresh green grass. (Not USDA Certified Organic).
- When mixed in a shaker or mini blender, Whey Cool dissolves easily in water or other liquids with no clumping and no grainy taste.
- The milking cows are never subject to any chemicals, hormones, antibiotics, genetically modified organisms, hyper-immunizations or injected pathogens. Nor are they given bovine growth hormone or any other hormones - NO rBST or rBGH.
Whey Cool Nutrition Rivals Raw Milk! Even today's most expensive dietary supplement whey products - isolates, ion exchange, concentrates and hydrolyzed forms - are denatured by-products of cheese manufacture that have definite limitations in preserving the biological activity of the whey proteins. Pasteurizing destroys enzymes, diminishes vitamins, denatures (damages) fragile milk proteins, destroys vitamin B12 and vitamin B6, kills beneficial bacteria and promotes pathogens. Pasteurized cow's milk is the number one allergic food in this country. Additionally, once the protein is denatured, the vital protein bound fats have been removed. From this point on there is little heat added and some of these whey proteins products are then referred to as undenatured or cold process. However, it is not possible for a protein to be undenatured. Most protein shakes are nothing more than cheese by-products. Whey Cool Protein Shake naturally contains exceptional levels of non-denatured Lactoferrin, Immunoglobulins, Active Peptides and Growth Factors. Raw milk, on the other hand, is truly one of the most profoundly healthy foods you can consume, which is why Whey Healthier never uses cross-flow filtration, microfiltration, ultrafiltration, hydrolyzation, ion exchange, or any process that would denature the original protein roserum, found in Whey Cool Protein Shake, is an exceptional quality natural whey protein, and the result of years of work to perfect a proprietary filtration and drying which involves the minimum amount of processing. This means you get the full range and highest levels of the most important components of native whey protein including Lactoferrin, an iron-binding, iron-modulating protein that enhances iron absorption when needed, also anti-viral, anti-bacterial and anti-inflammatory properties Immunoglobins with numerous immune system benefits. Bovine Serum Albumin, along with Lactoferrin and immunoglobins, contain generous amounts of Cysteine and Glutamine, necessary for Glutathione (GSH) production. Active Peptides (specialized paired amino acids) that exhibit a beneficial information transfer factor effect on the immune system as well as boosting intracellular Glutathione. Growth Factors (growth promoting protein fractions) are contained within the protein bound fats. Their function is to: regenerate all aged or injured cells in the body, build and retain muscle, process energy more efficiently, fight infections and help regulate blood sugar and brain chemicals. Whey Cool whey protein powder is an exceptional-quality Non-denatured Biologically Active Whey Protein and far more potent than any protein you'll find in any other shake.
Whey Healthier's full-range biologically active whey protein contains naturally occurring cysteine -the optimal component for the intracellular production of glutathione (GSH), our master antioxidant and detoxifier. Cysteine is very scarce in today's modern diet and therefore glutathione deficiency is prevalent. If cysteine undergoes any heating or processing, as all conventional dairy products do, it is denatured and converted to cystine. |

Glutathione -- Your Body's Own NATURAL Antioxidant
Antioxidants are vitally important for the function of a healthy immune system, as they neutralize the free radical activity in the body. Glutathione (GSH) is essential to your immune system acting as your body's primary antioxidant, detoxificant and anti-aging factor.
Science has already confirmed what can happen to your body when Glutathione is depleted:
Your immune system may not adequately protect you - Immune Depressed individuals have lower GSH levels when fighting disease. Lymphocytes, cells vital for your immune response, depend on GSH for their proper function and replication. Immunology 61: 503-508 1987. |
You may age more rapidly - As we age, there is a precipitous drop in GSH levels. Recent research indicates that propensities toward many degenerative diseases and aging itself are related to the capacity of the cell to robustly recover from oxidative insult. The capacity of a cell to recover from such insult can be determined by measuring the intracellular stores of Glutathione. Noelle et al., 1981 |
Your athletic performance may be compromised - Strong muscular activity generates oxyradicals leading to muscle fatigue and poorer performance. GSH neutralizes these radicals. Whey proteins promote muscular development. Sports Medicine 21; 213 - 238, 1996. |
Your liver is more vulnerable to toxins, pollution, and radiation -- The liver is the main detoxification organ of the body. In the liver we find very high concentrations of GSH, as it is a major factor in numerous biochemical detoxification pathways. GSH detoxifies many pollutants, carcinogens and poisons, including many found in fuel exhaust and cigarette smoke. It retards damage from radiation such as seen with loss of the ozone. Annual Review of Biochemistry 52 : 711-780 1983. |
Glutathione is our body's best-kept secret in the war against free radicals. GSH, a tripeptide composed of the amino acids cysteine, glutamine, and glycine, is found in a larger ratio in non-denatured whey protein, like the Proserum used in Whey Healthier, compared with any other proteins ingested by humans.
Grass Fed Cows Mean More CLA and EFA's for You
The milk used in Whey Cool Protein Shake is only from cows that graze on pesticide-free, chemical-free, natural grass pastures. Grass fed cows milk has much higher levels of Conjugated Linoleic Acid (CLA) and proper balance of essential fatty acids.
Whey Cool uses only grass fed milking cows that are never subject to any chemicals, hormones, antibiotics, genetically modified organisms, hyper-immunizations, injected pathogens - or any bovine growth hormones. That means more CLA for you! |
CLA is a fatty acid found in beef and dairy fats. Scientific interest in CLA was stirred in 1988 when a University of Wisconsin researcher discovered its cancer-fighting properties in a study of rats fed fried hamburger. CLA cannot be produced by the human body, but instead is obtained through foods such as whole milk, butter, beef, and lamb.
Agricultural Research dairy scientist Larry Satter, based at the Dairy Forage Research Center in Madison, Wisconsin, conducted a study comparing the amount of CLA in milk from cows grazing on pasture to the amount from cows fed hay or silage.
Satter concluded that pasture-grazed cows had 500% more CLA in their milk than those fed silage. Whey Healthier's grass-fed milking cows provide you a terrific source of CLA!

Elevation of plasma cholecystokinin (CCK) immunoreactivity by fat, protein, and amino acids in the cat, a carnivore.
Backus RC, Rosenquist GL, Rogers QR, Calam J, Morris JG.
Department of Molecular Biosciences, University of California, Davis 95616, USA.
The cat requires a diet high in protein and certain nutrients that are found only in animal tissue. It is possible that secretogogues of intestinal CCK in the cat may be different from those observed in non-carnivorous species. Plasma CCK concentrations were determined in cats (n = 6) given by oral-gastric tube either casein, whey protein, corn oil, or corn starch suspended in water. CCK was measured by RIA with a tyrosine sulfate-specific, C-terminal antibody, DINO. HPLC of plasma revealed that most CCK-immunoreactivity (CCK-LI) was associated with CCK-33 and a late eluting peak, presumably CCK-58. Casein, whey protein, and corn oil increased (P < 0.05) post-administration plasma CCK-LI, and at least for casein, the effect was dose related. An amino acid mixture approximating the residue composition of casein increased plasma CCK-LI (P < 0.05), however, the increase tended to be less than that caused by casein. Evaluation of post-administration levels of plasma amino acids indicated that intact protein and amino acids in the intestinal lumen affect CCK release by different mechanisms. Collectively, the results indicated that although cats are carnivores cats and humans secrete CCK in response to the same nutrients.

The active component in bovine milk on the proliferation of osteoblastic MC3T3-E1 cells was purified and identified. Growth-promoting activity was measured by [(3)H]thymidine incorporation on the cell. The molecular weight of the purified protein was 10 kDa. The amino-terminal sequence of this 10-kDa protein was identical to bovine high mobility group protein (HMG) 1. This 10-kDa protein is suggested to be a basic protein and to have an HMG box, a consensus sequence motif among the HMG family. From these results, we named this protein HMG-like protein. HMG is a ubiquitous nonhistone component of chromatin and considered to be implicated in DNA replication. We found this protein in milk, and it showed a growth-promoting activity. We propose the possibility that HMG-like protein existed in milk and plays an important role for neonate in bone formation by activating osteoblasts.

Milk is recommended as an excellent calcium source for bone health. Moreover, milk is considered to contain other components effective for bone health. In our previous studies, using an unfractionated bone cell culture system, we found that milk whey protein, especially its basic fraction (milk basic protein [MBP]), suppressed bone resorption. In this present study, we investigated whether MBP could prevent bone loss in aged ovariectomized rats. Twenty-one 51-week-old female Sprague-Dawley rats were ovariectomized (ovx), and another seven rats received a sham operation (sham). After a 4-week recovery period, the ovx rats were separated into three groups, and they were then fed a control diet, a 0.01% MBP diet (0. 01% casein of the control diet replaced with MBP), or a 0.1% MBP diet for 17 weeks. The sham rats were fed the control diet. Bone mineral density (BMD) of the femur was measured by dual-energy X-ray absorptiometry in vivo. The BMD in the ovx-control group noticeably decreased during the experimental period in comparison with that in the sham group. However, the BMD in the OVX-0.1% MBP group was significantly higher than that in ovx-control group at weeks 12 and 16 (p < 0.05). After the 17-week feeding period, the breaking energy of the excised femur of all groups was determined by use of a three-point bending rheolometer. The breaking energy in the ovx-control group was significantly lower than that in the sham group (p < 0.05). However, the breaking energy in the ovx-0.1% MBP group was significantly higher than that of the ovx-control group (p < 0.05). Urinary deoxypyridinoline (D-Pyr) level of the ovx-control group was higher than that of the sham group, whereas the level of D-Pyr excretion in the ovx-0.01% MBP and ovx-0.1% MBP groups was significantly lower than that of the ovx-control group (p < 0.05). These results suggest that MBP suppresses the osteoclast-mediated bone resorption and prevents bone loss caused by ovariectomy. Moreover, we performed an in vitro study using isolated osteoclasts from rabbit bone to investigate the possible mechanism. MBP dose-dependently suppressed the number of pits formed by these osteoclasts. This result indicates that MBP suppresses bone resorption by its direct effects on osteoclasts. To our knowledge, this study provides the first evidence that MBP directly suppresses osteoclast-mediated bone resorption, resulting in the prevention of the bone loss that occurs in ovx rats.

[Nutritional physiology of whey and whey components]
[Article in German]
Barth CA, Behnke U.
Deutsches Institut fur Ernahrungsforchung, Bergholz-Rehbrucke, Deutschland.
Deriving from positive effects of whey drinking cures in antiquity, the Middle Ages and modern time, a review is given on nutritional significance of whey. The proteins are essential components of whey and belong to the proteins with highest biological value because of their amino acid composition. Besides, they show fundamental functional properties, which enable a varied application in foods, dietetic foods and beverages in form of different whey products (powder, protein concentrates and isolates). Whey proteins have found considerable usage in infant's nutrition as whey predominant formulas as well as whey protein hydrolysates in case of cow's milk protein intolerances. A recent field of research are biological active peptide sequences which become effective during digestion and are of importance for secretion of entero hormones as well as for immune enhancing effects. They may contribute to assess the biological value of whey proteins under enlarged points of view and to develop new application forms and areas. It is pointed to further fields of application (e.g. adipositas, gout, kidney insufficiency). Concerning the quantitatively most dominant lactose in whey, it is dealt with its importance for the healthy development of infants (adaptation to the increased lactose content of mother's milk) as well as with lactose intolerance and galactosaemia. In case of mineral salts of whey it is emphasized the high nutrient density of calcium (prophylaxis for osteoporosis), the beneficial Ca:P and Na:K proportions (antihypertensive in case of the last one), the promotion of absorption of mineral salts by lactose, and the high content ofiodine. The whey is rich in B-vitamins, which contribute essentially for their satisfaction or requirement in case of a corresponding consumption. To be emphasized is the vitamin B12 in milk and whey, which is the sole source of this indispensable nutrient for blood-formation and cell division in lacto-ovo-vegetarian nutrition. In conclusion, a summarizing dietetics valuation of whey is performed.

Department of Biochemistry and Molecular Biology, University of Granada, Spain.
The aim of this study was to evaluate the effect of two sources of dietary nitrogen (isolated whey protein and hydrolyzed whey protein) on the intestinal repair of malnourished rats at weaning. The malnutrition was achieved by a 3 days' starvation period. Normally fed male Wistar rats were used as controls. Intestinal repair was studied after a refeeding period of 4 days. The parameters studied included nitrogen balance, lactase, sucrase, isomaltase, and maltase activities of the jejunum; liver acetylcholinesterase and glutamate dehydrogenase activities; and the serum amino acid profile. In addition, tests of intestinal permeability to macromolecules were performed by measurement of ovalbumin and beta-lactoglobulin in serum. Both diets of led to the recovery of the severely starvedrats, in terms of the values of all the parameters evaluated. The serum beta-lactoglobulin was the only exception, because its concentration was significantly lower in the normally fed animals. This study suggests that the intestinal mucosal barrier is not completely repaired, even after a 4-day refeeding period, to the point of being suitable to accept an increase in the uptake of antigens.

[The dietary correction of the permeability of the protective intestinal barrier in rats after gamma irradiation]
[Article in Russian]
Gmoshinskii IV, Radchenmko SN, Zorin SN, Mazo VK.
400 to 700 rad irradiation with gamma-rays significantly increased the intestinal permeability for ovalbumin and polyethylene glycol in rats. Consumption of cow's milk with a protein concentrate for 14 days prior to irradiation helped to normalize the disturbed permeability. The findings suggest the possibility of prophylactic use of milk for risk group subjects with acute or chronic radiation injuries.

BACKGROUND: Oral administration of zinc or bovine whey-derived growth factor extract (WGFE) is known to reduce intestinal permeability and ameliorate methotrexate (MTX)-induced mucositis, respectively. OBJECTIVE: We examined the effects of zinc, WGFE, and zinc plus WGFE on gut damage in MTX-treated rats. DESIGN: Rats (n = 16/group) were fed zinc (1000 mg/kg diet), WGFE (32 mg/kg diet), zinc plus WGFE, or control (10 mg Zn/kg diet) diets for 7 d and then injected subcutaneously with MTX (2.5 mg/kg) for 3 d to induce gut damage. Gut histology and intestinal permeability were assessed. RESULTS: The Zn+WGFE diet was associated with both reduced gut damage on day 5 and enhanced recovery on day 7. The WGFE diet ameliorated gut damage, whereas the Zn and Zn+WGFE diets enhanced repair. Gut metallothionein and tissue zinc concentrations were significantly (P < 0.01) higher with Zn and Zn+WGFE on days 5 and 7 than without zinc supplementation. The Zn and Zn+WGFE diets significantly (P < 0.05) decreased gut permeability on days 3-4 compared with the control diet. Intestinal permeability was significantly (P < 0.05) increased on days 5-6. On days 6-7, only the WGFE diet improved gut permeability (by 80%) compared with the control diet. CONCLUSIONS: Dietary administration of WGFE and a pharmacologic dose of zinc reduced intestinal damage and enhanced recovery, respectively. WGFE also improved gut permeability after MTX-induced bowel damage. In combination, zinc and WGFE hastened repair of gut damage, which may have clinical application in chemotherapy-induced mucositis.

BACKGROUND: One-week triple therapy is the most frequently recommended treatment for Helicobacter pylori infection. Eradication rate is satisfactory, nevertheless is advisable to look for more effective therapies. AIM: To test the efficacy of a standard triple therapy plus bovine lactoferrin in the eradication of H. pylori infection. PATIENTS AND METHODS: One hundred and fifty consecutive H. pylori positive patients, suffering from dyspeptic symptoms were recruited in a 7-day triple therapy open randomised single centre study with rabeprazole, clarithromycin, tinidazole, bovine lactoferrin (group A) or rabeprazole, clarithromycin, tinidazole (group B), or a 10-day therapy with rabeprazole, clarithromycin, tinidazole (group C). H. pylori status was assessed 8 weeks after the end of the treatment by means of a 13C-urea breath test or a H. pylori stool antigen-test. RESULTS: Eradication rates (intention to treat/per protocol) were: group A (92.2/95.9%), group B (71.2/72.5%) and group C (70.2/75%). The efficacy of triple therapy added with lactoferrin was significantly higher than other two regimens (p=0.01, intention to treat analysis; p=0.005, per protocol analysis). CONCLUSION: These results suggest that lactoferrin tested in the present study was effective in curing H. pylori and could be a new agent to assist the antimicrobials in the eradication of the bacterium.

Cryptosporidium parvum produces a prolonged watery diarrhea unresponsive to conventional antimicrobials. Because of reported efficacy of antibody-based immunotherapy, we studied the effect of inexpensive, commercially available oral bovine serum concentrate (BSC) in experimental cryptosporidiosis. Twenty-four calves were treated with 57 g/d BSC (n = 12) or soy protein (n = 12) added to their standard whey protein-based milk replacer (227 g/2 L twice daily). Of the 24, 9 were also treated with L-glutamine (GLN), 8 g/L (50 mM) in the milk (5 calves in the BSC group and 4 in the soy group). Animals were inoculated with 10(8) cryptosporidium oocysts per os on d 8 of life and received oral rehydration on d 12-14. Eight uninfected controls were treated with BSC or soy protein. Fecal and urine volume and urinary Cr-EDTA excretion were measured. Animals were killed on d 18 of life. Cryptosporidiosis induced severe watery diarrhea lasting >9 d and produced a 25% increase in intestinal permeability, a 33% decrease in villous surface area, and a 40% reduction in mucosal lactase specific activity. Glutamine treatment had no effect on the diarrhea or any of the intestinal tests; and therefore pooled data were used to compare the 12 calves treated with BSC with the 12 treated with soy. In animals receiving BSC, peak diarrheal volume and intestinal permeability were reduced 33%, fewer oocysts were shed, intestinal crypts were significantly deeper, and villous surface area returned to normal by 9 d after infection (all p <or= 0.05). BSC should be studied as a treatment for human cryptosporidiosis.

Epidemiological and experimental studies suggest that dietary milk products may exert an inhibitory effect on the development of several types of tumors. Some recent experiments in rodents indicate that the antitumor activity of the dairy product is in the protein fraction and more specifically in the whey protein component of milk. It has been demonstrated that whey protein diets result in increased glutathione (GSH) concentration in a number of tissues, and that some of the beneficial effects of whey protein intake are abrogated by inhibition of GSH synthesis. Whey protein is particularly rich in substrates forGSH synthesis. It has been suggested that whey protein may be exerting its effect on carcinogenesis and VIH infection by enhancing GSH concentration. Lactoferrin, one of the proteins contained in whey has also been studied in this way. It has been suggested that lactoferrin binding may play an important role in maintaining, optimal mononuclear phagocyte function, thus protecting adjacent tissue against phagocyte derived radicals. Moreover it has been demonstrated by one of us that the level of plasma lactoferrin were decreased in HIV-1 infected patients in relation to the progression of the disease. The aim of the present study is to evaluate in rat the reactive oxygen species, scavenger activities (ROSSA) of red blood cells (RBCs) with a multifermented whey (SK 344), by repeated doses during 16 days. This study has permitted to demonstrate in vivo that the SK 344 has an excellent ROSSA corresponding to a limitation of the lipoperoxidation of RBCs membranes by singlet oxygen and nitric oxide. We can conclude that whey protein, lactoferrin and multifermented whey are good candidates as dietary inhibitors of the oxidative stress and should be considered as potential medicinal foods in various pathologies as HIV infection and cancer.
