In my quest to find the purest protein powder available, it became very apparent that the processed nature of almost all protein powders today renders them challenging for the body to digest. In a healthy body, when proteins are broken down, denatured or hydrolyzed into amino acids by the hydrochloric acid (HCl) in the stomach, very little free non-toxic L-glutamic acid is released. When proteins are hydrolyzed in a food manufacturing plant, an abundant amount of toxic D-glutamic acid is released.
For some reason, this toxic form of D-glutamic acid is readily absorbed into the blood – unlike the natural L-glutamic acid, which mostly passes through undigested into the feces. When the D-glutamic form acid enters the blood stream, it can easily combine with a sodium molecule and form MSG (mono-sodium glutamic acid). MSG is a nervous system stimulate that amps ups the taste buds response to a flavor. While it might make bland food taste better, it can over-work the nervous system and is considered a toxin.
While most folks are only reactive to this in high doses, such as when used as a flavor enhancer, most protein powders are ripe with the toxic form of D-glutamic acid.
The only protein powder I have been able to source thus far is a pure, undenatured whey protein powder. The process is incredibly simple. The whey is simply drained off the curd, filtered for impurities, and dried. There is no processing, denaturing or hydrolyzing of the whey protein. When adhering to this very natural process, the whey protein is undenatured.
Undenatured Whey Protein Powder: LifeSpa Whey Pure
Whey Pure is a natural, nutritionally advanced, bioactive whey protein concentrate containing naturally-occurring immunoglobulins that support the delicate balance of the body’s immune system. The whey is sourced from New Zealand cows, where herds are free from environmental contaminants and are not subjected to hormones and antibiotics that are commonly used elsewhere. This undenatured whey protein is a rich source of amino acids, including those needed for the synthesis of glutathione – an important antioxidant that can be depleted by stress. This formula is resistant to stomach acid and supports intestinal health. The 80% protein content supports lean body mass.
Why Whey Pure?
Whey protein is one of the two major proteins in cow’s milk. The New Zealand herds used for producing Whey Pure are not given hormones and are not intentionally infected with a pathogen to force them to make antibodies specific to that pathogen.
Boosts Natural Immunity
Whey Pure is a whey protein, rich in immunoglobulins (antibodies) that are preserved using very careful techniques under controlled temperature and pH. During a series of filtration steps, lactose and water are removed from a slurry of whey. Special care is taken to maintain the integrity of the antibodies and to optimize the protein complex. In comparison to fluid cow’s milk and ordinary whey protein concentrate, Whey Pure contains significantly greater concentrations of proteins and immunoglobulins. Whey Pure can be used not only as a high biological value protein source for healthy individuals, but also to provide immunoglobulins to those in need. The immunoglobulins it contains are almost identical to those of the mammalian species and resist peptic digestion. The immune-balancing effect of immunoglobulins supports the body’s normal defense mechanisms. (1,2)
Benefits the Lymph
Each antibody in Whey Pure (IgG1, IgG2, IgM, and IgA) has a specific role in immune function:
- IgM responds quickly to an antigen, specifically to bacteria and viruses.
- Later in the response, IgG1 and IgG2 attack viruses and toxins.
- IgA is critical in the body’s immune system.
- The immunoglobulins also contribute to the humoral immunity of the gut-associated lymphoid tissue (GALT).
Naturally Builds Muscle
Among Whey Pure’s ingredients is a high concentration of the branched-chain amino acids leucine, isoleucine, and valine, which can be used by skeletal muscle during stress and to support nitrogen utilization. The semi-essential amino acid, arginine, increases the activity of natural killer and lymphokine-activated cells, as well as IGF-1 (insulin-like growth factor-1). (1)
Boosts Antioxidant Activity
Cysteine and the non-toxic natural form of glutamate are found in higher concentrations in Whey Pure than in other high-biological-value proteins. These amino acids serve as precursors to glutathione, (3) an endogenous antioxidant especially needed during stress, exercise, and poor nutrition.
Lactoferrin, alpha-lactalbumin, beta-lactoglobulin, and bovine serum albumin are other proteins in Whey Pure that contribute to glutathione synthesis and support immune function. (3,4)
Blood Sugar and Body Composition Support
Supplementation with whey protein may support glucose metabolism and muscle protein synthesis in humans. (5)
In a group of women, whey protein improved body composition, but soy protein did not. (6)
In conclusion, I’ve been searching for a high quality undenatured whey protein for years, and I am thrilled to say I finally found one that makes and exceeds the cut.
Suggested Use of Whey Pure: Mix 2 scoops with a cold beverage or add to your favorite recipe once daily or as recommended by your healthcare practitioner. To prevent protein denaturation and maintain the protein activity level, do not mix in hot drinks or recipes that require baking or boiling. Also, do not mix with pineapple or papaya because their enzymes may deactivate the protein. Children and pregnant or lactating women should consult their healthcare practitioner prior to use.
