What is Native Whey Isolate?

During the first month after a baby's birth, a time when strong anabolism is really important, the mother's breast milk is composed of more than 90% whey rich in bioactive components.
These bioactive elements serve as a motor for the infant's muscle growth. This unique anabolic potency can be found in Nutrimuscle's native whey isolate.

What are the benefits of Native Whey Isolate?

Quickly absorbed proteins
Nutrimuscle native whey isolate is ideal in the morning to revive muscle anabolism when you have an empty stomach, and immediately after a training session thanks to its rapid absorption.
Muscle growth
A specially adapted protein supply for athletes for building and maintaining muscle mass.
Appetite suppressant effect

Nutrimuscle native whey isolate is unbeatable in moderating your appetite. Native whey isolate and Bacillus Coagulens

Nutrimuscle flavoured native whey isolate contains GanedenBC30® Bacillus Coagulans. This increases the assimilation of amino acids, optimises your health, and fights against digestive issues (such as bloating) that may arise as a result of a high calorie intake or a diet, both of which are particularly rich in protein.

Nutrimuscle Native Whey Isolate

Nutrimuscle's Native Whey Isolate:

  • Contains an optimal protein concentration at the rate of 90% (which corresponds to 95% on the dry extract);
  • Is very low in salt. The sodium intake is minimal with a content of 0.1% (100 mg per 100 g of product);
  • Ensures a significant intake of potassium (400 mg per 100 g) and calcium (250 mg per 100 g);
  • Is lactose free: the intake of lactose (sugar which causes digestive problems in some) is almost zero. The maximum guaranteed content is 0.2%, that is to say 200 mg per 100 g of product;
  • Is low in fat (maximum content of 0.4% or 400 mg or 3.6 calories of fat per 100 g) and sugar (less than 2 g or 8 calories of carbohydrate per 100 g);
  • Contains no trace of gluten, no GMOs, no antibiotics, no irradiated product;
  • Has a neutral taste. It does not contain any sweetener (especially no aspartame) or coloring.

As no enzymatic process was used, Nutrimuscle's Native Whey Isolate is virtually tasteless. When it comes to anabolism, it's the quality of the protein that makes all the difference. While protein supplements were once only supplements capable of replacing, more or less well, dietary protein, current technical progress makes it possible to produce proteins of a much higher anabolic quality than those obtained from food.
In this, Nutrimuscle Native Whey Isolate truly represents a revolution in quality.
Nutrimuscle only sells 100% native protein, especially when it comes to whey. The total Nutrimuscle protein is filtered like that of Boirie.

Usage tips

Who is native whey isolate for?

Native whey isolate is for:

  • Athletes, for a high-quality protein intake and an increase in muscle mass.

When should I take native whey isolate?

Thanks to perfect solubility in your stomach acid, the protein in Nutrimuscle's native whey isolate is digested very quickly. That's why Nutrimuscle native whey isolate takes effect so quickly after consumption.
Within 10 minutes, the amino acids in the native whey isolate make it into your bloodstream.
The level of amino acids in your blood remains high for 1 hour.
After 1 hour, it'll be time to take Nutrimuscle native whey isolate again, or eat a high-protein meal.

First thing in the morning
Take 30 g of Nutrimuscle native whey isolate to stop catabolism induced by your overnight fast and restart anabolism (1). Because of its rapid absorption, Nutrimuscle's native whey isolate is ideal in the morning to immediately revive muscular anabolism, which is depleted by your overnight fast.
You'll need a high dose of protein to fill your empty stomach first thing in the morning, because at this time your digestive system takes a lot of the protein from that first meal. Upping your intake ensures that your muscles also receive all the protein they need. (5) This anabolically disastrous situation explains why simply eating protein in the morning almost triples the rate of anabolism (6).

Between meals
Between meals, 20 g of whey isolate boosts muscle anabolism.

In the evening
Taking 30 g of Nutrimuscle native whey isolate just before bedtime can replace nocturnal catabolism with a powerful anabolistic effect.

Before a training session
Taking 20 g of Nutrimuscle native whey isolate 45 minutes before a workout gets your muscles ready for exercise.

During a training session
To combat catabolism and muscle fatigue, drink 15 g of Nutrimuscle native whey isolate every 20 minutes during your workout.

After a training session
Consume 50 g to 60 g of Nutrimuscle native whey isolate immediately after exercise to optimise anabolic response. In combination with dextrose, the isolate accelerates recovery speeds, which is important for athletes who train every day or even several times a day (2).

How do I take native whey isolate?

Nutrimuscle native whey isolate is flavourless, but has a natural, slightly milky taste. It can be consumed as is or sweetened with Nutrimuscle's sucralose. You can also add variety by opting for a Nutrimuscle native whey isolate flavoured with chocolate, strawberry, vanilla, or banana... whatever you fancy!

How do I prepare and consume my proteins?
Gas generated by the consumption of protein powder do not come from the protein itself. It mainly comes from the temperature of the liquid in which it is diluted. Cold liquid, which is often too cold, consumed several times a day in high quantities (1.5 to 2 litres) creates a thermal shock in the digestive system, causing bloating, gas, or even a case of the runs if you're very sensitive. 

Nutrimuscle recommends consuming its protein products in a room-temperature liquid: prepare your protein in the morning in a bottle and then consume throughout the day. You have a smooth, even mixture, because the bubbles have evaporated. So, say goodbye to burps! What's more, the ambient temperature of the contents will not disturb your digestion, so gas is also a thing of the past.

A mixture to be prepared with care
As it has not undergone any chemical processing and is made of native proteins, Nutrimuscle native whey isolate should not be excessively shaken once in water or milk, otherwise a high level of foam will be produced. 

Using a blender (the metal blades destroy the growth elements naturally present in milk) is not recommended: they reduce the anabolic impact of Nutrimuscle's native whey isolate. Instead, we recommend mixing with a fork, or very gently with 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.

Mixing with other Nutrimuscle products

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

  1. BCAA 4.1.1 Constructors is the richest in leucine to optimise anabolism. BCAA 2.1.2 Resistance is rich in leucine and valine to combat catabolism and training fatigue

Compared to casein, Nutrimuscle native whey isolate results in a less significant rise in valine. In order to optimise anabolism, we therefore recommend combining it with BCAA 2.1.2 Resistance, which is richer in valine. It would be less advisable to do the opposite, which would further unbalance the aminogram instead of rebalancing it to make it more favourable to anabolism.

Synergies between supplements
Nutrimuscle native whey isolate improves the assimilation of biotics, carnitine, and creatine.

Adverse reactions between supplements
To avoid bloating, Nutrimuscle native whey isolate is not to be taken at the same time as potassium bicarbonate.

Purity of raw materials guaranteed

It's rare for consumers to have access to the names of the suppliers of the raw materials that go into the supplements they consume. However, this is essential to ensure product traceability.
At Nutrimuscle, we only use top-of-the-range proteins the quality of which is guaranteed by world leaders. LACTALIS INGREDIENTS produces Nutrimuscle native whey isolate at its HACCP- and ISO9001-certified factory in France. What matters most to us is the quality of the raw materials, your health, and the results you achieve using our nutritional supplements.

Quality is essential in our proteins, such as Nutrimuscle native whey protein isolate, which is consumed often (every day or even several times a day) and in large quantities.

Manufacturing method

Throughout its manufacturing, Nutrimuscle Native Whey Isolate has received constant attention with regard to the concern for non-denaturation of the protein. Four features really make the difference with other proteins:

No cheese protein derived from milk
Traditionally, whey comes from waste from the cheese industry. This means that manufacturers have added bacteria (in order to ferment the milk) and enzymes (in order to curdle the milk). They then remove the juice (whey) from the cheese thus obtained, a bit like removing the serum that floats on the surface of yoghurts. The big advantage is that this waste that was once thrown into the sewer is not expensive, which explains the drop in the price per kilo of classic whey.

By using native dairy serum proteins, the native Nutrimuscle whey isolate is made from a noble, undamaged raw material, not from a cheese waste that has undergone chemical transformations detrimental to the good assimilation of the protein. In addition, depending on the type of cheese made, the composition of conventional whey fluctuates from batch to batch. A serum protein native to milk does not experience these variations in quality.

No heat treatment
Thanks to an innovative membrane extraction technique, the native whey isolate Nutrimuscle is obtained cold, that is to say without heating denaturing the amino acids and therefore their anabolic power.
The milk is first microfiltered in order to eliminate fat and bacteria. It is then that the whey is ultrafiltered by a cold process (temperature below 10 °), which is quite unique, because this avoids the concentration processes that take place when hot.

Only natural, non-chemical filtrations are used. Thus, the growth factors, naturally present in milk, are perfectly preserved while they are destroyed by heat.
For example, the TGF intake is 95 µg per 100 g. This TGF (Transforming Growth Factor) plays an important role in the maturation of muscle stem cells (satellite cells) as well as in their transformation into mature muscle cells (1).

No GMP (glycomacro-peptides)
In addition to the lower denaturation of amino acids, the native whey isolate Nutrimuscle Dairy has the advantage over cheese proteins derived from milk that it does not contain glycomacro-peptides (GMP). The presence of GMP in a whey testifies to the denaturations which 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.

GMPs decrease the absorption of whey by inhibiting the secretion of acid in the stomach (acid essential for breaking down whey into amino acids) (2). Their presence will therefore require more effort and more time on the part of the digestive system to cut the whey into smaller peptides. Who says slower absorption, says lessening of the anabolic action of whey (3).

It was once thought that the benefit 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 have no value, neither for muscle gain nor for fat loss (4 - 5). They therefore constitute an unnecessary dead weight for the athlete. Thanks to the absence of GMP, the native whey isolate Nutrimuscle 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 in order to avoid chemical processes.

Nutrimuscle Native Whey Isolate is "non-instant." Therefore, it does not contain transgenic soy (GMO) and has not undergone ionizing radiation treatments.

Benefits of native whey isolate in more detail

Muscle growth

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 increases the rate of muscle protein synthesis (anabolism) by 0.016% per hour. When whey is used right after training, its anabolic impact more than doubles, with an anabolism rise of 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 Native Whey Isolate is unmatched for moderate appetite (3). It is therefore quite suitable for gaining lean muscle or when dieting.

Healthy digestive system by taking Bacillus Coagulens
The goal of taking Bacillus Coagulans GanedenBC30® is to:

  1. Increase the assimilation of amino acids, in particular for key amino acids for anabolism such as leucine and especially glutamine which it is very difficult to assimilate correctly,
  2. Optimize health: the proliferation of pathogenic bacteria in the digestive system generates a large number of toxic substances. By fighting against these bad bacteria, Bacillus Coagulans GanedenBC30® induce surprising effects 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.
