- Micro and ultra filtrated instant whey protein isolate (milk protein)
- Guar gum (stabilizer - except for natural flavor)
- Sunflower lecithin (emulsifier) *
- Sucralose sweetener (except for natural flavor)

Additional ingredients per flavor: Forest-Strawberry: aroma, beetroot colorant; Cafι Latte: instant coffee (0.07% caffeine in the final product); Chocolate: skim cocoa powder; Lemon: aroma, acidity regulator citric acid; Vanilla, Banana, Coconut: aroma; Tropical Fruit: aroma flavor, acidity regulator citric acid, sunset yellow FCF colorant; Blackcurrant: aroma, beetroot colorant, anthocyanins (grape skin extract).

* Sunflower lecithin (less than 0.5%!) is a healthy oil-like substance which is sprayed on the protein powder for the purpose of instantisation. Sunflower Lecithin ensures that whey protein can be easily dissolved in a liquid. Lecithin is an essential component of cell membranes in the entire human body.

Low Price, High Quality 

A lot of protein for less money. That is Pure Whey Protein Isolate from Power Supplements. A pure, very soluble, and tasty whey protein isolate with a high protein content of 90% and a very low fat and lactose content. And this at a very low price! The price is even comparable to that of low-protein whey concentrates (65-80% protein). Even more so with this very economical bag of 15 kg.

The indicated protein percentage is based on dry weight. On the bottom of this page you can find a detailed explanation.

Whey or whey protein is regarded by many as the best source of protein to increase fat free muscle mass and for faster muscle recovery after sports or weight training. It is also perfect for a protein diet and to lose fat the healthy way. 

A whey protein isolate is the most effective way to do this. It is also easier to digest than a whey protein concentrate. 

All the quality benefits when choosing Pure Whey Protein Isolate: 

  • A high percentage of protein (90%) and very low percentage of fat (0,4%) and carbohydrates (4%, of which 2,5% lactose).
  • European brand product (Volactive). 
  • Very soluble.
  • Free of aspartame and cyclamate. 
  • Delicious flavors. 
  • Also available: natural flavor, free from additives and with 93% protein.
  • Prepared with the cold cross flow microfiltration process, in which the natural structure of the proteins is preserved as much as possible.
  • Contains unique vulnerable peptides that support the immune system and promote muscle recovery. 
  • The growth-promoting peptides and high content of branched chain amino acids (BCAA) make this whey protein isolate the optimal pre- and post-workout protein source.

All the price benefits when you choose Pure Whey Protein Isolate: 

  • Very economical. This bag of 15 kg is sufficient for 500 protein shakes!
  • Quantity discount at two bags.
  • Choice of free products from €25, €50 and €100. With this bag of 15 kg you can choose as 3e free product from expensive items like Bio Bulk Oats 5000g, BCAA 200 caps, Creapure creatine 600g or Natural Multi 90 caps.

The protein with the highest biological value

Whey protein is a protein with a very high 'biological value'. This value is higher when a protein contains more essential amino acids, and when these amino acids are present in a good ratio. Essential amino acids are building blocks that our body cannot go without. They are required to maintain, repair and build up our body. 

Of all the dietary proteins whey protein isolate contains the highest known biological value and is therefore the most suitable protein for physical recovery!

Pure Whey Protein Isolate from Power Supplements contributes safely to:

For athletes 

  • Faster muscle recovery after exercise 
  • Increase in muscle strength after power training

In a (protein) diet  

  • Reduction of muscle breakdown 
  • Faster muscle recovery after exercise 
  • Optimization of the fat burning process


  • Support of the immune system


This high-tech whey protein isolate is prepared with Cross-Flow Microfiltration at low temperature. This production process ensures minimal damage to the natural structure of the protein. The protein fractions that support the immune system and promote muscle recovery remain intact. The biologically active Glycomacropeptide, which is lost in 'ion exchange' process, is also maintained.

Pure Whey Protein Isolate contains the following protein fractions: 

- Beta Lactoglobulin 49%
- Glycomacropeptide 24%
- Alpha Lactalbumin 21%
- Immunoglobulin G 4%
- Bovine serum albumin 2%

Average amino acid profile (percentage of protein):

- Alanine 4.9%
- Arginine 1.9%
- Aspartic acid 10.8%
- Cystine 2.3%
- Glutamic acid 17.2%
- Glycine 1.6%
- Histidine 1.6%
- Isoleucine 6.8% *
- Leucine 10.2% *
- Lysine 9.3%
- Methionine 2.0%
- Phenylalanine 3.0%
- Proline 4.6%
- Serine 4.4%
- Threonine 7.0%
- Tryptophan 1.6%
- Tyrosine 3.0%
- Valine 6.0% *
* = BCAA (Branched Chain Amino Acids)

Additional information about the protein content: 

Raw material produces traditionally indicate the protein content in protein powders based on dry weight. Providers of protein supplements then use this information for their product specifications. 

Protein powders, however, are not completely dry. For example, a filtered whey protein isolate usually contains about 4-5% moisture. In reality, the content of protein in Pure Whey Protein Isolate is therefore about 4-5% lower than the 90 to 93% protein which is determined based on dry weight. 

For Pure Whey Protein Isolate (natural) the protein content based on dry weight is 93%. After adjustment of 4-5% for moisture content, we detect at a protein content of 88-89%. As far as we know this corrected protein percentage is the highest of all available protein powders in Europe.

For all flavors of Pure Whey Protein Isolate, except for natural, about 3% aroma, stabilizer and sweetener has been added. The protein percentage in dry form is about 90%. After correction for moisture content the corrected protein content percentage equals 85-86%. There is some variation here because different flavors contain different amounts of aroma (see table below).

Laboratory analysis Whey Isolate Power Supplements

Following up on the commotion surrounding spiked protein products in The Netherlands, it makes sense that some doubt among consumers has been cast concerning the content of protein products. Do they really contain what the label says?

Our formulas are clear; a protein powder with the least possible additions, so no fructose, dextrose and other sugary fillers. Aside from that our aromas do not secretly contain loose glycine and alanine in order to fraudulently increase protein levels.

In response to the commotion Power Supplements sent some products to an independent laboratory (NutriControl) for verification. Below are some of the results for the analysis of the Pure Whey Protein Isolate, flavor Vanilla-Stevia (per 100 grams):

- Moisture: 5.3g
- Dry protein: 91.4g (higher than claimed)
- Raw Protein: 86.6g
- Carbohydrates: 2.1g, of which lactose 0.7g (lower than claimed)
- Alanine: 4.7g (equivalent to natural value)
- Glycine: 1.5g (equivalent to natural value)
