What are the benefits of Whey & Oat Lean Gainer Isolate for you?

Fast energy supply & better muscle sensations

The Lean Gainer Isolate of Whey & Oats Nutrimuscle provides a source of energy quickly usable by the body. It can therefore be taken before training to benefit from its effects during exercise.

Our lean gainer contains oats rich in beta-glucans (super fiber) and native whey isolate obtained by microfiltration and cold ultrafiltration. Thanks to this combination of quality carbohydrates and bio-active ingredients, it allows you to better feel your muscles while benefiting from a rapid energy supply.

Digestive health

The oatmeal we use is beneficial for digestive health thanks to its richness in beta-glucans. These super-fibers help nourish the good bacteria in the intestinal flora and reduce irritation of the intestine.

Our native whey isolate is very easily digested thanks to its gentle extraction process that does not denature the protein. It is also lactose-free and does not pose a problem for people with lactose intolerance.

Moderate appetite suppressant effect

The lean gainer isolate of whey & oats Nutrimuscle allows a calorie intake of quality without weighing on the stomach for all that. It can be taken as a replacement for a meal for example and / or just before training.

The native whey isolate of Lean Gainer Whey & Oats Nutrimuscle

The native Nutrimuscle whey isolate is obtained cold using an innovative membrane extraction technique, that is to say without heating denaturing the amino acids. This allows them to maintain their anabolic effects.

The milk is first microfiltered in order to eliminate fat and bacteria. The whey is then ultrafiltered by a cold process (temperature below 10 °). The filtration techniques used are natural.

Organic oats from Lean Gainer Whey Isolate & Nutrimuscle oats

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

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.
