Pure Gainer Protein Nutripure Neutral - Optimise Muscle Mass Gain

Pure Gainer Nutripure Neutral – 1.2 kg Bag

The Pure Gainer Nutripure is a dietary supplement designed for athletes who need to increase their daily calorie and protein intake without overloading their solid meals. Its unique formula combines micronised oat flour, milk proteins and patented bovine collagen peptides. One 80g serving delivers 316 kcal, 28g of protein and 35g of carbohydrates, 5.7g of fat — all with no added flavourings or sweeteners in this neutral version.

A dietary supplement for muscle mass gain

Most gainers on the market rely on maltodextrin or fast sugars that encourage low-quality weight gain. The Pure Gainer Nutripure takes the opposite approach, building its formula around micronised oat flour at 65% of the product. Oats are a complex carbohydrate that releases energy gradually, without a sharp blood sugar spike.

This approach targets a cleaner mass gain, where each serving feeds muscle building rather than generating unnecessary fat storage. This is what sets this gainer apart from products focused on raw calorie volume, and what makes it a relevant tool for muscle mass gain day after day.

What does the Pure Gainer Nutripure contain? A unique formula

The ingredient list of the neutral Pure Gainer is deliberately short and easy to read: micronised oat flour (65%), milk protein concentrate (17%), patented low-molecular-weight bovine collagen peptides (14%), medium-chain triglycerides (MCT) from coconut oil, acacia gum as a thickener, and lactase as a digestive enzyme.

The addition of lactase is a notable detail: this digestive enzyme supports the absorption of milk proteins, making the product more accessible for athletes sensitive to lactose. Acacia gum, a natural soluble fibre, acts as a gentle thickener without altering the composition. The result is a genuinely all-in-one product: carbohydrates, proteins, collagen peptides and MCT-derived fats, all in a single formula.

28g of protein and 35g of carbohydrates: a ratio designed for muscle building

Per 80g serving (2 scoops), the Pure Gainer delivers 316 kcal, 28g of protein, 35g of carbohydrates (of which only 2.7g are sugars) and 5.7g of fat. This carbohydrate-to-protein ratio has been calibrated to support muscle building without turning every serving into a calorie bomb.

The 28g of protein provide a complete profile of essential amino acids, including the BCAAs naturally present in milk proteins. It is this profile that supports protein synthesis after exercise. The collagen peptides, for their part, contribute around 11g of additional structural protein per serving, complementing the milk proteins on a functional level.

Native whey and milk proteins: a quality protein source

Nutripure works from fresh milk, using a process that preserves the native structure of the proteins. The milk protein concentrate used in the Pure Gainer follows the same logic: a non-denatured protein source with moderate digestion, well suited to mass gain phases where the goal is to maintain a sustained amino acid level over time.

This approach is consistent with Nutripure's native whey isolate, born from the same quality commitment: proteins sourced from milk, without denaturation. For pure protein intake outside of a mass gain phase, the native whey isolate remains a fully valid option — complementary to the Pure Gainer, not competing with it.

Patented collagen peptides: a real asset for athletes' joints

The Pure Gainer is the first Nutripure gainer to include collagen directly in its formula. More specifically, patented low-molecular-weight bovine collagen peptides (2000 daltons) for optimal absorption.

Collagen is a structural protein found notably in joints and connective tissues such as tendons and ligaments. With around 11g of collagen per serving, the Pure Gainer provides meaningful support for strength training athletes who place heavy demands on their joints during every session. This direct integration removes the need to stack a separate collagen product alongside the gainer.

A growing body of scientific research highlights the interest of patented collagen peptides at low molecular weight for their bioavailability. For athletes under a heavy training load, this makes for a smart addition to muscle building.

Why a neutral-flavour Pure Gainer?

Unlike the vanilla or chocolate versions, the neutral version contains no added flavourings or sweeteners. This is a deliberate choice for versatility: this gainer fits into all your preparations — porridge, homemade smoothies, protein pancakes, plain yoghurt — without imposing an artificial taste.

It is also the choice for maximum simplicity in terms of composition. For athletes who want a product as clean as possible, with no steviol glycosides or added flavourings, the neutral version delivers exactly that level of purity. It mixes easily with water or milk (dairy or plant-based) in a shaker, and the flavour can be tailored to your taste (cocoa, banana, peanut butter, and so on).

Who is this Nutripure gainer for?

The Pure Gainer Nutripure is aimed first and foremost at athletes who struggle to meet their daily calorie needs through solid food alone. Typical profiles include ectomorphs with a fast metabolism, strength training athletes hitting a plateau, high-intensity athletes (CrossFit, powerlifting) and long-distance runners carrying a heavy training load.

For beginners in strength training, this is also a highly relevant product. Many make the mistake of focusing solely on whey protein while overlooking carbohydrates. Without enough calories, it becomes hard to build muscle, even with serious training. The Pure Gainer simplifies this equation by covering both needs in a single serving — protein for protein synthesis, carbohydrates for energy.

Conversely, the Pure Gainer is not suited to a cutting or weight loss phase. In that case, it is better to turn to a pure protein isolate such as the native whey isolate, which provides protein without the extra calories.

How to use the Pure Gainer to get the most from your sessions?

The official Nutripure directions recommend mixing 2 scoops (80g) in 300 ml of water or milk (dairy or plant-based) in a shaker. To be taken as a snack between meals or immediately after training, to support recovery and muscle growth.

The post-training window is particularly relevant: at that moment, the body is calling for carbohydrates to replenish glycogen and protein to restart protein synthesis. The Pure Gainer mix covers both needs in a single serving, making it a practical tool around your sessions and in the post-exercise window.

Depending on your calorie needs, you can move to two servings per day to target faster mass gain. For athletes with more moderate needs or those returning to sport, a single daily serving is often enough. The 1.2 kg bag provides around 15 servings, which works out to two to four weeks of use depending on your routine.

Pure Gainer or Native Whey Isolate: how do you choose?

These two Nutripure products answer different needs. The native whey isolate (over 94% protein, less than 0.2% lactose) is a very pure protein isolate, ideal as a straight post-training option, during a cutting phase, or as a supplementary protein source without extra calories. It is a whey protein with fast, immediate absorption.

The Pure Gainer, on the other hand, is a more complete and more calorie-dense product, designed specifically for muscle mass gain. It combines complex carbohydrates, milk proteins and collagen. The two can sit alongside each other without overlap: the native whey isolate for pure protein intake, the Pure Gainer as a snack to meet your daily calorie targets.

A product made in France, certified anti-doping
