When searching for a protein supplement, it's important to consider the following four "pillars" to ensure you're getting the highest quality and most bio-available protein possible.
The Highest Biological Value (BV) Protein is measured with a Biological Value (BV) which refers to how well and how quickly your body uses the protein that you consume. The higher the BV of the protein, the more nitrogen your body can absorb, use, and retain, promoting the most lean muscle gains.
Whey protein has the highest BV with a value of 104, while soy protein is at a distant 74. Beef, eggs, and fish also measure high, though not as high as whey. Plant-based proteins are measured much lower, so it's optimal to get your protein from an animal source.
Whey protein is rich in the amino acids critical for developing and sustaining new muscle mass. It contains every essential amino acid, plus some of the non-essential ones, making it a complete protein. In fact, whey provides more Branch Chain Amino Acids (BCAAs) than any other protein source.
The BCAAs are leucine (mentioned above), valine and isoleucine. These make up one third of the amino acid profile of your muscles. The BCAAs’ most important job is to assist in synthesizing other amino acids that muscle building requires, including glutamine. Whey supports your immune system by raising levels of glutathione – a tiny molecule that’s found in every cell as its ‘master’ antioxidant and detoxifier. It is one of your body’s best-kept secrets in the war against free radicals and the normal signs of aging.
eWhey Organic Protein is cold-processed ensuring the highest BV. It’s digested so rapidly that it increases the refueling speed of your muscles during that critical time just following your workout.
Organic & Pasture-Raised If you do choose to go with an animal source for your protein, it's best to choose grass-fed animals which are higher in essential fatty acids such as CLA (conjugated linoleic acids) and lipolic acid. They typically have three to five times more CLA than grain-fed animals. CLA supports healthy body composition levels.
Free-grazing cows are humanely raised and will never see the inside of a feedlot. Compare that to where your typical whey protein comes from; CAFO (Concentrated Animal Feeding Operations) are generally raised in filthy, crowded conditions. CAFO cows are typically feed GMO grain diets (especially corn) which create a much higher level of acidity in the animal’s stomach, leading to many health problems.
Organic ensures the whey is derived from cows that have access to natural pastures not treated with pesticides, fertilizers, genetically modified (GM) ingredients or other harmful chemicals. The cows are never treated with antibiotics or growth hormones such as rBGH/rBST. Studies have shown that synthetic growth hormones used to increase milk production in non-organic dairy cows may be carcinogenic and can also be linked to early onset of puberty in preteen girls. A four-year long, $25-million EU study into organic food, the largest of its kind to date, found that milk from organic herds contained up to 90 percent more antioxidants.
Cold-Processed and Non-Denatured Cold-processing leaves the protein unaltered (non-denatured) by heat, chemicals, or enzyme action which ensures all the natural qualities are unchanged. As mentioned above, cold-processing retains the maximum BV of all the key amino acids, protein fractions and beneficial micronutrients present and intact, promoting a healthy immune function and healthy flora balance.
Don't be fooled by the term "undenatured" - it is not possible for a protein to be undenatured. Once a protein is denatured, it cannot be refolded.
Concentrate (Not Isolate) This is the least processed form of whey, so it contains the most beneficial compounds and a complete spectrum of amino acids (including BCAAs) and immuno-supportive nutrients. ēWhey™ still contains the vital protein-bound fats naturally present in raw milk and is assimilated by your body much easier than any protein isolates. Protein isolates are acid/ion exchange processed protein which denatures the amino acid profiles by using acids and chemicals to separate the whey from the fats. Protein isolates are deficient in key amino acids and nutritional cofactors.
