Avoid diluting Nutrimuscle native whey isolate in chlorinated water such as tap water, as some of the bacteria in GanedenBC30® Bacillus Coagulans would be destroyed.

What is the Native Whey Isolate (Lactase fortified)?

The Native Whey Isolate is obtained directly from milk using low temperature membrane technologies: microfiltration and cold ultrafiltration.
In contrast to the lactose-reduced native whey isolate, the native whey isolate easy shake is lactase fortified, as it naturally contains lactose and has not undergone a process to remove the lactose. Its higher carbohydrate content allows for better miscibility and makes it easier to use.

What are the benefits of the Native Whey Isolate (Lactose fortified) for you?

Rapidly assimilated proteins
Nutrimuscle native whey isolate easy shake is a protein that is assimilated very quickly by the body. This type of protein is therefore very practical to take in the morning when waking up to revive muscle anabolism and immediately after training.

Muscle growth
Nutrimuscle native whey isolate  helps provide the protein intake needed by athletes to maintain and increase muscle mass.

Appetite suppressant effect
Nutrimuscle native whey isolate is a protein that can be used for appetite moderation during dry periods.

Native whey isolate and Bacillus Coagulans
Nutrimuscle flavoured native whey isolate easy shake contains GanedenBC30® Bacillus Coagulans. The presence of these biotics makes it possible to cumulate several benefits for the athlete: a better assimilation of amino acids and the preservation of digestive system health. Athletes on a high-protein diet may be prone to bloating or digestive problems. GanedenBC30® Bacillus Coagulans help to combat these problems.

Native whey isolate and lactase
For better lactose digestion, we have added the enzyme tolerase-l-lactase from the producer DSM which facilitates the destruction of lactose in the intestine and allows people who have difficulty digesting dairy products to be able to take supplements without experiencing digestive discomfort.

Proteins contribute to the development and maintenance of muscle mass.

Usage tips

Who is the Nutrimuscle Native Whey Isolate (Lactose fortified) for?

The native whey native isolate (Lactose fortified) is for:

  • Athletes, to provide them with quality proteins and to increase their muscle mass.

When should I take Native Whey Isolate (Lactose fortified)?

Thanks to perfect solubility in stomach acid, the proteins in Nutrimuscle native whey isolate (Lactose fortified) are digested very quickly. The action of the Nutrimuscle native whey isolate thus starts very quickly after taking:

  1. Within 10 minutes, the amino acids of the native whey isolate reach the blood;
  2. For 1 hour, the level of amino acids in the blood remains high;
  3. 1 hour after taking it, it will be time to take Nutrimuscle native whey isolate again or eat a high-protein meal.

When waking up
Use 30g of Nutrimuscle native whey isolate

to interrupt catabolism induced by night-time fasting and restart anabolism (1). Because of its rapid absorption, the Nutrimuscle native whey isolate is ideal in the morning, to immediately revive muscular anabolism, depressed by night-time fasting.

In fact, in the morning, after the night fast, you have to wake up with a mega-dose of protein, because at that time, the digestive system will take a very large part of the protein from that first meal. Upping your intake ensures that your muscles will also receive all the protein they need (5). This anabolically catastrophic situation explains why simply eating protein in the morning almost triples the magnitude of anabolism (6).

Between meals

Between main meals, 20g of whey isolate can increase the level of muscle anabolism.

In the evening

Taking 30g of Nutrimuscle native whey isolate just before bedtime helps to counteract nocturnal catabolism and generate a powerful anabolism in its place.
Before a training session
Taking 20g of Nutrimuscle native whey isolate 45 minutes before a workout prepares the muscles for exercise.
During a training session
Drinking 15g of Nutrimuscle native whey isolate every 20 minutes during training reduces catabolism and muscle fatigue.
After a workout
An intake of 50g to 60g of Nutrimuscle native whey isolate immediately after exercise allows the anabolic response to be optimised. Native whey isolate and dextrose are taken to speed up the recovery rate. This is crucial when the training sessions are close together. (2).

How do I take Nutrimuscle Whey Native Isolate (Lactose fortified)?

Flavourless, with a natural, slightly milky taste, Nutrimuscle native whey isolate  can be eaten as is or sweetened with Nutrimuscle's sucralose. You can also add variety by choosing a Nutrimuscle native whey isolate flavoured with chocolate, strawberry, vanilla or banana, according to what you fancy.

How do I prepare and consume my proteins?
You must be careful not to dilute your proteins in a liquid that is too cold. This can lead to thermal shock in the digestive system and thus cause bloating or gas.
We therefore recommend that you consume your protein in a liquid that is room temperature. You can make your mix in the morning in a bottle to take later in the day. Thus, the mixture will be homogeneous, at room temperature and without bubbles.

A mixture to be prepared with care
Nutrimuscle native whey isolate  has not undergone any chemical process and consists of native proteins. To avoid “foaming” the mixture too much in the water or milk, avoid shaking it for a long time. 

We do not recommend the use of blenders. Their metal knives destroy the growth factors that are naturally present in milk. Nutrimuscle native whey isolate will then be less effective.

We advise you to mix the preparation slowly with a fork or a whisk. If you don't like the slightly pasty texture, let it sit for a minute so that the protein dissolves completely on its own in the liquid.

Interactions with other Nutrimuscle products

Protein and BCAA
This study (7) sheds new light on the profile of the BCAA that you must take with your protein.
There are two different forms of Nutrimuscle BCAA:

  1. BCAA 4.1.1 Constructors which are the richest in leucine to optimise anabolism. 
  2. BCAA 2.1.2 Resistance This is the first time that a new product has been developed that is rich in leucine and valine to fight against catabolism and fatigue related to training.

Compared to casein intake, Nutrimuscle native whey isolate induces less valine elevation. In order to optimise anabolism, it is therefore advisable to associate it with the BCAA 2.1.2 Resistance, which is richer in valine. It would be less advisable to do the opposite, as it would cause further imbalance in the aminogram instead of rebalancing it in order to create an environment more conducive to anabolism.

Synergies between supplements

Nutrimuscle native whey isolate improves the assimilation of biotics, carnitine and creatine.
Antagonisms between supplements
Nutrimuscle native whey isolate is not to be taken at the same time as potassium bicarbonate, to avoid bloating.

Guaranteed purity of raw materials

At Nutrimuscle, we only use top-of-the-range proteins whose quality is guaranteed by leading international players: INGREDIA produces the Nutrimuscle Native Whey Isolate (Lactose fortified) in its HACCP and ISO certified plant. 

What is important to us is the quality of the raw materials, your health and the results you will get by using our nutritional supplements. 

The milk comes from France and Belgium.
This quality is essential for proteins such as Nutrimuscle native whey protein isolate (Lactose fortified) which is a product that you often take (every day or even several times a day) and in large quantities.

Manufacturing process

Throughout its manufacture, the Nutrimuscle native whey isolate (Lactose fortified) has received constant attention due to the concern for protein non-denaturation. Four features really make the difference in comparison with other proteins:

No milk-derived cheese protein
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 juice (whey) from the resulting cheese, much like removing the whey that floats on the surface of yoghurt. The big advantage is that this waste that used to be thrown down the drain is not expensive, which explains the lower price per kilo of classic whey.

By using native dairy serum proteins, Nutrimuscle native whey isolate (Lactose fortified) is derived from a high quality raw material that has not deteriorated, not from cheese waste that has undergone chemical transformations that are detrimental to the proper assimilation of the protein. In addition, depending on the type of cheese produced, the composition of classic whey varies from one batch to another. A native milk serum protein does not experience these variations in quality.

No heat treatment
Thanks to an innovative membrane extraction technique, Nutrimuscle native whey isolate is obtained cold, i.e. without the heating process that denatures the amino acids and thus their anabolic power. The milk is first microfiltered to remove fat and bacteria. The whey is then ultra-filtered using a cold process (temperature below 10°), which is quite unique, as it avoids the concentration processes that take place when hot. Only natural, non-chemical filtration is used. Thus, the growth factors, naturally present in milk, are perfectly preserved whereas they would be destroyed by heat.

For example, the TGF content is 95 µg per 100g. This TGF (Transforming Growth Factor) plays an important role in the maturation of muscle stem cells (satellite cells) and their transformation into mature muscle cells (1).

No GMP (glycomacropeptides)
In addition to the lower denaturation of amino acids, the Nutrimuscle native whey isolate has the advantage over
milk-derived cheese proteins of not containing glycomacropeptides (GMP). The presence of GMP in a whey shows the denaturing that the
amino acids have been subject to during the cheese making process. As their name indicates, GMPs are an agglomerate of sugars (up to 30%) and amino acids
(up to 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 for the breakdown of whey into amino acids) (2). Their presence will therefore require more effort and more time from the digestive system to break down the whey into smaller peptides. Slower absorption means a reduction in the anabolic action of whey (3).

For a while it was thought that the advantage of GMPs was to reduce appetite thanks to their stimulating effect on appetite suppressant hormones. Unfortunately, this is not the case, which means that GMPs are of no interest, either for muscle gain or for fat loss (4 - 5). They are therefore an unnecessary dead weight for the athlete. Due to the absence of GMP, the Nutrimuscle native whey isolate easy shake contains 17% more essential amino acids (especially leucine) than a conventional isolate. 

No chemical or genetic manipulation
At Nutrimuscle, we prefer to use quality proteins to avoid chemical processes. 

Nutrimuscle native whey isolate (Lactose fortified) is “non-instant”. Therefore, it does not contain genetically-modified soy (GMO) and has not been treated with ionising radiation.

Benefits of Nutrimuscle native whey isolate (Lactose fortified) in more detail

Muscle growth

In an anabolic study, young men were given 15 g of whey on an empty stomach or after a weight training session (4). On an empty stomach, taking whey increased the rate of muscle protein synthesis (anabolism) by 0.016% per hour. After training, whey intake increased anabolism even more significantly by around 0.041% per hour. This study shows that the increase in muscle sensitivity to whey anabolism lasts for more than 24 hours after training.

Appetite suppressant effect
Nutrimuscle easy shake native whey isolate is a very effective protein in reducing appetite (3). It is therefore quite suitable for gaining lean muscle or for use while dieting.

Healthy digestive system by taking Bacillus Coagulens
Taking Bacillus Coagulans GanedenBC30® allows you to:

  1. Increase the assimilation of amino acids, in particular for key amino acids for anabolism such as leucine and especially glutamine which is difficult to assimilate,
  2. Optimize health: the proliferation of pathogenic bacteria in the digestive system generates a large number of toxic substances. By fighting these bad bacteria, Bacillus Coagulans GanedenBC30® have benefits against joint pain, poor sleep, etc.
  3. Fight against digestive disorders such as bloating that can be felt with a high calorie diet or diet, both particularly rich in protein. At least 100 million Bacillus Coagulans spores must be used per day for effects to occur (2).

Proteins contribute to the development and maintenance of muscle mass.
