Contains the full range of fragile immune modulating and regenerative protein components naturally present in fresh, raw milk from cows grass-fed year-round on natural pastures!
Vital Whey is a delicious, 100% natural nutritional protein supplement. It is perfect for adults and children. It can be taken before meals or between meals to help manage hunger and energy levels.*
Vital Whey is a proprietary, non-denatured, native whey protein produced to maintain the full range of all the fragile immune-modulating and regenerative components naturally present in fresh, raw milk! The milk for Vital Whey comes from cows that are grass-fed and graze year-round on natural pastures. Our whey does not contain genetically engineered materials. It is hormone-treatment-free, pesticide-free, chemical-free, and undergoes minimal processing. No wheat, gluten or preservatives.
Vital Whey is produced with a unique pasteurization method that does not use high heat and utilizes a proprietary filtration and drying method. It involves the minimum amount of processing required by law: single flash pasteurization for 15 seconds at 161 degrees F.
The result is a microbial safe product that exceeds all standards. This whey protein is not a by-product of cheese manufacture. We do not use cross-flow filtration, microfiltration, hydrolyzation or ion exchange because these methods denature the original protein components.
This superior whey protein powder contains the highest amounts of the glutathione precursor covalent bonded cysteine. Additionally, Vital Whey contains the full range and highest levels of the most important protein components: Lactoferrin, Immunoglobulins, Serum Albumin, Active Peptides and Growth Factors.
Unlike isolated protein powders, whereby the proteins have been pulled away from their nutritional cofactors causing a possible depletion of Vitamin A, ours is a complete whey protein concentrate.
Vital Whey vs other whey protein products
Vital Whey is made with Proserum, the finest native whey protein available. Proserum is the result of years of work to perfect a system that produces only the highest quality native whey protein*.
As a comparison, the following graph can be used to show the measurable difference between Proserum native whey protein and those of our competitors for three fragile protein components that are quickly damaged if over processed:
Even the most expensive whey products available (they can be concentrates, isolates, ion exchange and hydrolyzed) are commercial denatured by-products of cheese manufacture. The vast majority is from grain-fed cows and even ones that claim to be grass-fed are still fed grain or hay in the colder months. Organic is not a helpful standard to look for, as most all organic milk is from grain-fed cows.
All commercial production dairy products have definite limitations in preserving the biological activity of the whey proteins. The vital immune and regenerative components are destroyed from the commercial processing they all undergo. The milk and whey goes through a high heat pasteurization process twice, chemical modification and pH regulation to produce cheese and whey. Each of these steps damages/ denatures** the whey proteins. The damaged proteins are then filtered out and what remains is a narrow range of "undenatured" proteins that have survived the cheese and whey manufacturing process. Additionally, the vital protein-bound fats have been removed. From this point on there is little heat added and some of these whey protein products are then referred to as undenatured/cold process. It is not possible to undenature or restore the full biological activity of a protein if it has been damaged.
Vital Whey is the made with the finest native whey protein available and stands in a class of its own. This whey protein powder is far more potent than any whey products available.***
The importance of Cysteine vs Cystine
Cysteine (covalent bonded cysteine) is naturally-occurring. There are exceptional levels of it contained in Vital Whey proteins. It is the optimal component for the intracellular production of glutathione (GSH). Cysteine is very scarce in our modern diet, thereby limiting glutathione production, making glutathione deficiency prevalent in those consuming the Standard American Diet. If cysteine undergoes any standard pasteurization heating or processing, as all conventional dairy and dairy by-products do, it is denatured and converted to cystine.
Cystine is the form that is found in all of the commercial and claimed high-end whey proteins, as they are all by-products.
Vital Whey is unique as it is the only native whey product that contains naturally occurring cysteine (covalent bonded). Bonded cystine, very different than covalent bonded, has become a marketing term and it is misleading. Two cysteine molecules bonded together form cystine. It is created by denaturation (damage) to the milk and whey from induced heat and/ or pH stressors from the manufacture of cheese. This unbreakable bond forms a cystine molecule that is difficult for the body to utilize as a precursor for intracellular glutathione production.
Regarding Whey Protein Concentrate: The journal Immunology
reports: The bioactivity occurs through the ability of the protein concentrate to help replenish Glutathione levels via continuous dietary provision of Glutathione precursors, especially cysteine, during lymphocyte proliferation, thus supporting an optimal immune response. This process seems to not only increase intercellular levels of Glutathione and precursors at the time of ingestion, but also builds up stores of these substances within the cells which lasts for a substantial post-ingestion time interval."

* Native: a: Relating to the naturally occurring conformation of a macromolecule, such as a protein. Constituting the original substance or source, b: found in nature especially in an unadulterated form.
* Native Protein: The concept of a protein in its natural state, in the cell, unaltered by heat, chemicals, enzyme action, or the exigencies (distress) of extraction.
** Denature: To cause the tertiary structure of (a protein) to unfold, as with heat, alkali, or acid, so that some of its original properties, especially its biological activity, are diminished or eliminated.
***Based on analysis of protein as determined by an independent laboratory using the SDS PAGE Gel method. This is the industry accepted method to determine the actual biological activity of a milk protein.
