Throughout the manufacturing process, Nutrimuscle's organic native whey isolate receives constant care and attention to ensure that the molecular structure of the protein isn't altered.
Four features really make it stand out in comparison with other proteins:
No organic cheese protein derived from milk
With the rise in organic produce came the rise of the organic cheese industry. Traditionally, whey is made from the waste products of the cheese industry. This means that manufacturers have added bacteria (to ferment the milk) and enzymes (to curdle the milk). They then remove the juices (whey) from the resulting cheese, much like draining away the liquid that floats on the surface of a yoghurt. The big advantage is that this by-product that used to be thrown away is cheap, which explains the lower price per kilo of classic whey and the attractive price of cheap organic whey.
Using organic native dairy serum proteins, Nutrimusclees organic native whey isolate is derived from a non-deteriorated and organic high-quality raw material, not from cheese waste that has undergone chemical processing that is detrimental to the proper assimilation of the protein. Additionally, depending on the type of cheese produced, the composition of classic whey varies from one batch to another. A native milk serum protein is not subject to these variations in quality.
No heat treatment
Thanks to an innovative membrane extraction technique, Nutrimuscle's organic native whey isolate is obtained cold, meaning no heat is used, which would damage amino acids and thus their anabolic power. Austrian organic milk is first microfiltered to remove fat and bacteria. The organic native whey is then ultrafiltered. Only natural, non-chemical filtration is used. Thus, the growth factors naturally present in milk are perfectly preserved, whereas heat would destroy them. For example, the TGF content is 95 µg per 100g. This TGF (Transforming Growth Factor) plays an important role in the maturing of muscle stem cells (satellite cells) and their transformation into mature muscle cells (1).
No GMPs (glycomacro-peptides)
In addition to the lesser denaturing of amino acids, Nutrimuscle's organic dairy native whey isolate has an advantage over milk-derived cheese proteins: it does not contain glycomacropeptides (GMPs). The presence of GMPs in whey is evidence of the denaturing of the amino acids during the cheese making process.
As their name suggests, GMPs are a mixture of sugars (30%) and amino acids (70%).
GMPs are particularly low in leucine, the most anabolic amino acid for muscles. GMPs decrease whey absorption by inhibiting the secretion of acid in the stomach (acid essential to the breakdown of whey into amino acids; 2). Their presence will therefore require more time and effort from the digestive system to break the whey down into smaller peptides. Slower absorption means a reduction in the anabolic effect of whey (3).
For a while it was thought that the advantage of GMPs was their ability to reduce appetite thanks to their stimulating effect on the appetite-suppressant hormones. Unfortunately, this is not actually the case, which means that GMPs are of no interest either for muscle gain or fat loss (4-5). They are thus an unnecessary load for athletes to carry. Thanks to the absence of GMPs, Nutrimuscle's organic native whey isolate contains 17% more essential amino acids (especially leucine) than a conventional isolate.
No chemical or genetic modifications
At Nutrimuscle, we prefer to use high-quality proteins in order to avoid chemical processing.
Nutrimuscle's organic native whey isolate is 'non-instant'. Therefore, it does not contain transgenic soy (GMO) and has not been treated with ionising radiation.
