What is Nutrimuscle's Lean Gainer Whey & Oats?

Designed for controlled weight gain thanks to its balanced ratio of proteins and carbohydrates, and unlike the “consumer” gainers on the market, Nutrimuscle's Native Whey & Organic Oats Lean Gainer is: 

  • Made from very high quality organic oats
  • Mixed with the only ceramic microfiltration dairy whey on the market
  • Suitable for muscle building while limiting fat intake
  • Easy to use in many situations (pre/post training, cooking etc.
  • Ideal for controlling your daily calorie intake

What are the benefits of Nutrimuscle's Lean Gainer Whey & Oats for you?

Increased muscle sensation & energy intake
The Nutrimuscle native whey & organic oats lean gainer is the ideal muscle food to prepare for physical effort with top quality energy intake. Rich in the super-fibres contained in its oats and in bio-active ingredients naturally present in its dairy whey, it provides increased muscle tone sensations combined with an energy intake that is felt very quickly: 

  • Better muscular congestion
  • Improved muscle-brain connection
  • Increased endurance during training etc.

Digestive health
Thanks to the unique quality of the extraction
of native whey coupled with its ceramic microfiltration process, the native whey lean gainer does not cause digestive problems for most users despite its lactose content. The organic oat flakes will help maintain your digestive health thanks to their high fibre content.

Appetite suppressant effect
The purpose of a gainer is to be able to consume it in addition to your meals to increase your calorie intake in a qualitative way without weighing down your stomach, which is what the Nutrimuscle whey & oats lean gainer is all about. Effective in both these areas, it can also quickly replace a meal without leaving you with the impression of not having eaten and will make you feel satisfied.

For more details on the benefits of the whey & oats lean gainer, consult the Learn more section.

1. Protein contributes to the development and maintenance of muscle mass.

2. Carbohydrates contribute to the recovery of muscle function (contraction) after very intense and/or prolonged physical exertion resulting in muscle fatigue and depletion of glycogen stores in skeletal muscle. The benefits are obtained by consuming carbohydrates from all sources, with a total intake of 4g per kg of body weight per dose within 4 hours, and at the latest within 6 hours, of very intense and/or long-lasting physical exertion that has led to muscle fatigue and depletion of glycogen stores in skeletal muscle.

Nutrimuscle Native Whey Protein & Oats Lean Gainer

Derived directly from protein dairy and not cheese proteins derived from milk, whey of dairy origin has the definite advantage of not having been denatured during its extraction.

The latest addition to Nutrimuscle, the filtration process of native whey protein is improved thanks to ceramic microfiltration which is the latest innovative technology which allows to obtain a native whey of superior quality with an excellent aminogram.

Nutrimuscle Organic Whey & Oats Lean Gainer

A source of low glycemic index carbohydrates (around 40) and high in fiber, Lean Gainer's powdered oatmeal slows the absorption of carbohydrates, which reduces insulin surge.

Made by Davert, the German leader in organic flakes, the organic oats that make up the Lean Gainer are of very high quality.

The powdering of organic oats is made by Nutrimuscle in its factory for perfect control of the granularity of the powder and its quality thanks to grinding on a stone wheel.

Usage tips

Who is Nutrimuscle Whey & Oats Lean Gainer for?

The Nutrimuscle Whey & Oats Lean Gainer is for:

  • Athletes, for a supply of quality protein and carbohydrates for increased muscle mass;
  • Sedentary people due to its satiety effect with high quality ingredients
  • People who consume little protein in their diet.

When should I take Nutrimuscle Whey & Oats Lean Gainer?

Thanks to perfect solubility in stomach acid, the native whey protein of Nutrimuscle Whey & Oats Lean Gainer is digested very quickly. Its action thus starts quickly after it is taken:

  • Within 15 minutes, the amino acids in the bio-active concentrate are assimilated
  • For more than 2 hours, the blood level of amino acids remains high
  • three hours after taking it, it will be time to resume Nutrimuscle Whey & Oats Lean Gainer or to have a meal rich in proteins.

When waking up
On waking, use 100g to 150g of Nutrimuscle Whey & Oats Lean Gainer to quickly break the catabolism induced by night-time fasting (1). 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. Overdosing your intake ensures that your muscles will also receive enough protein to cover their needs (4).
This anabolically catastrophic situation explains why simply eating protein in the morning almost triples the magnitude of anabolism (5). 

Between meals
If your goal is controlled weight gain, 100g of Nutrimuscle Whey & Oats Lean Gainer between main meals will immediately provide you with extra anabolism thanks to the Lean Gainer whey, as well as quality caloric intake thanks to the organic oat powder.

In the evening
To limit nocturnal catabolism, taking 100g to 150g of Nutrimuscle Lean Gainer Whey & Oats just before bedtime can replace
nocturnal catabolism with powerful anabolism.

Before a training session
An intake of 100g to 150g of Nutrimuscle Whey & Oats Lean Gainer one hour before a training session prepares the muscles for the effort.

After a workout
Use 100g to 150g of Nutrimuscle Whey & Oats Lean Gainer immediately after exercise to optimise anabolic response and restore intramuscular glycogen stores.

How to take Nutrimuscle Whey & Oats Lean Gainer?

Do not dilute Whey & Oat Lean Gainer in chlorinated water such as tap water as you will kill some of the bacteria.

Interactions with other Nutrimuscle products

Protein and BCAA
There are 2 different forms of Nutrimuscle BCAA:

Compared to a casein intake, the Lean Gainer's native whey protein is less likely to induce valine elevation. In order to optimise anabolism, it therefore makes sense to use the lean gainer with BCAA 2.1.2 Resistance, which is richer in valine (7).

The opposite is irrelevant. Because even if the BCAA 4.1.1 Constructors are high in leucine, an unbalanced aminogram does not necessarily allow for better absorption of the excess leucine.

Synergies between supplements
Nutrimuscle Whey & Oats Lean Gainer improves the assimilation of biotics, carnitine and creatine.

Antagonisms between supplements
Nutrimuscle Whey & Oats Lean Gainer is not to be taken at the same time as potassium bicarbonate, to avoid bloating.

To deepen your knowledge and to understand how to use the 2 supplements that make up the Nutrimuscle Whey & Oats Lean Gainer, we invite you to consult the following product sheets:

1. Protein contributes to the development and maintenance of muscle mass.

2. Carbohydrates contribute to the recovery of muscle function (contraction) after very intense and/or prolonged physical exertion resulting in muscle fatigue and depletion of glycogen stores in skeletal muscle. The benefits are obtained by consuming carbohydrates from all sources, with a total intake of 4g per kg of body weight per dose within 4 hours, and at the latest within 6 hours, of very intense and/or long-lasting physical exertion that has led to muscle fatigue and depletion of glycogen stores in skeletal muscle.
