Thanks to their richness in bio-active ingredients, native milk serum proteins are used to replace breast milk. Bio-active (or native) whey are therefore the benchmark to ensure the growth of infants. Musclewhey Nutrimuscle is naturally rich in alpha-lactalbumin. A 10% improvement in nitrogen retention (reflecting better muscle protein synthesis) is noted between a whey enriched with alpha-lactalbumin low in GMP and a classic whey rich in GMP and beta-lactalbumin (3) .
Warning: most whey proteins qualified as bioactive are poor in growth factors, because they come from a process of extracting waste from cheese production which destroys myogenic factors.
In addition to the slightest denaturation of amino acids, Musclewhey Nutrimuscle dairy whey has the advantage, over cheese whey derived from milk, of not containing glycomacropeptides (GMP). The presence of GMP in a protein testifies to the denaturations that the amino acids underwent during the making of the cheese.
As their name suggests, GMPs are an agglomeration of sugars (up to 30%) and amino acids (up to 70%). GMPs are particularly low in leucine, the most anabolic amino acid for muscles. To make cheese, manufacturers put gastric juice rennet from the stomachs of calves in the milk to make it curdle. The casein micelles are thus destabilized and coagulate, giving rise to GMPs. When cheese makers get rid of whey (origin of whey), the latter is contaminated up to 20 to 30% by these GMP.
By using native dairy serum proteins, there is no reason to curdle the milk. The proteins of the whey protein Musclewhey Nutrimuscle do not undergo this deterioration, they do not contain GMP. This is why Musclewhey Nutrimuscle whey protein is certified GMP free.
No chemical or genetic manipulation
A simple chemical manipulation (known as “instantaneousization”) transforms poor quality, completely insoluble proteins into proteins that melt in water. At Nutrimuscle, we prefer to use quality proteins in order to avoid chemical processes.
Musclewhey Nutrimuscle whey protein is “non-instant”. Therefore, it does not contain transgenic soy lecithin (GMO) or carboxymethylcellulose (CMC) and has not undergone ionizing radiation treatments. This double quality is essential for proteins like Musclewhey Nutrimuscle whey protein, which is a food that you eat often (every day or even several times a day) and in large quantities.
Why is a lot of protein processed by calf rennet?
This manipulation occurs during the manufacture of the cheese. Rennet is essential for altering the molecular structure of milk proteins so that they become cheese. Technically, rennet is said to be used to flocculate the casein part of milk. The whey sellers then recover the waste that results from this chemical manipulation: the cheese whey derived from milk. The latter is therefore contaminated by calf rennet while its amino acids have been degraded during the reaction of transformation of milk into cheese.
At Nutrimuscle, we only use noble material for our whey. They come directly from milk, not cheese waste. Therefore, Musclewhey Nutrimuscle whey protein is not treated with calf abomasum. The integrity and the quality of the amino acids are therefore not altered and no animal residue foreign to the milk is present. Musclewhey Nutrimuscle whey protein is therefore a protein that is ideal for vegetarians who want to supplement with whey.
