100% Natural Whey (Stacker2 Europe)

Natural Whey

We met Stacker2 about 20 years ago with the production in the USA of very powerful fat-loss products. While the company’s range was constantly growing, came the European series of Stacker2 in 2010, which is autonomous and produces its own products, exclusively for the European market. The arrival of a separate series came to meet the European needs in sports nutrition, respecting all EU quality standards.

Supplement Nutritional Facts

Natural Whey Label
100% Natural’s Whey Label


  • Calories: 116 kcal /scoop
  • Protein: 23 gr. /scoop
  • Fat: 1.9 gr. /scoop
  • Carbohydrates: 1.3 g. /scoop (2g fiber and 0.9g sugar)

100% Natural Whey contains two types of proteins. Whey protein isolated (WPI) and Whey protein concentrated (WPC). Each scoop (30g) yields 45% of essential amino acids (EAAs), of which 5.4g. are branched chain amino acids (BCAAs) and 4g. glutamine.

Whey protein isolate (WPI)
Whey protein isolate is the highest quality form of whey consisting of at least 85% protein by weight.

Whey protein concentrate (WPC)
Whey protein concentrate is the product obtained by removing non-protein components from pasteurized whey, so that the final product yields more than 25% protein. WPC can give you a protein content from 25 to 80%. Although, 100% Natural Whey didn’t mention the percentage here, we hope that Stacker2 has included the maximum percentage of 80%.

Glutamine (4gr)

Glutamine is an amino acid that is found in abundance in the body. During high-intensity exercise, glutamine stores can be depleted, this shifts glutamine from conditionally essential amino acid to essential if your goal is to avoid premature fatigue and enhance recovery.

Branch chain amino acids (5.4 gr)

BCAAs are useful for stimulating muscle protein synthesis (MPS) and providing an easily accessible source of energy for muscles during training. In addition, they speed up recovery and help reduce delayed onset muscle soreness (DOMS). Consuming BCAAs during and after training not only helps rebuild new muscles (along with other amino acids), but also speeds recovery.

Available Flavors

Last but not least, 100% Natural Whey comes in four wonderful flavors: vanilla, chocolate, strawberry and yogurt. It does not contain artificial aromas, artificial colors, artificial sweeteners and artificial numbers E). The only sweetener it contains is Stevia (Stevia rebaudiana).

Finally, do not forget to thank the European Stacker2 for their quick response to my request to analyze some of their new products. An analysis of its new pre-workout, Extasis, will follow shortly. Stay tuned with a follow at our Instagram page.
