Summary

  • Whey powder is primarily used for food supply, but is also used for a so-called "whey bath" and far away for the preparation of "whey masks".
  • Whey powder can basically be divided into whey powder concentrate, whey powder isolate and whey powder hydrolysate. Each category offers a different composition of ingredients.
  • The concentrate is the cheaper option compared to the isolate, which is in the middle price range, and the hydrolysate, which is the most expensive price category. Each has its advantages and disadvantages, which are examined in more detail below.

The Best Whey powder: Our Choices

Guide: Questions you should ask yourself before buying a whey powder product

What is whey powder?

Whey powder consists of dried whey, which is a by-product of cheese production. It consists mostly of lactose (76%) and protein (13%). In common parlance, whey powder is also more commonly known as "Whey Protein".

What does whey powder do ?

Because of its composition, whey powder is often used as a diet companion. The high protein content not only has a satiating effect, but is also a real calorie eater due to the heavy processing in the body.

Furthermore, the potassium content in whey powder has the effect that water is withdrawn from the body and thus, especially at the beginning of a diet, the first kilos disappear quickly from the scales.Whey powder is also extremely popular for fitness training. Whey powder is usually additionally isolated, which means that all other ingredients (such as carbohydrates and vitamins) are filtered out.

A particularly fast absorption of the protein promises the body the necessary building blocks for muscle building after a training session.

Cosmetics is another area where whey powder is used. A daily glass of whey powder promises firm skin and shiny hair. A whey bath or face mask is also possible.

How do I take whey powder?

The easiest way is to dissolve whey powder in water or milk. So-called "shakers" are suitable for this purpose to guarantee that the powder dissolves perfectly in the water. The amount depends on whether you are very active in sports or not. A daily amount of 0.7g per kg of body weight is recommended.

However, if you are trying to build muscle in the gym, up to 1.7g per kg of body weight is recommended. A shake (=2-3 spoonfuls of Mole powder + 650 ML water), immediately after training, supports the regeneration and building of your muscles by supplying the necessary building blocks, so this is an ideal time to have a "shake". Another ideal time is early in the morning, when the body has used up its reserves overnight and is thirsty for new building blocks. Whey powder is the ideal solution due to its quick processing.

What does whey powder cost?

Prices in this area are very differentiated; the quality and type of whey powder plays a major role here. The cost per 1kg of whey powder varies between 13€ and 65€. Due to the large selection, there is a suitable product for every price range. The following is a brief overview of the price categories.

Type Price range per 1kg Protein content
Natural whey powder 14€-20€ 11%-15%
Whey powder concentrate 15€-35€ 70%-80%
Whey powder isolate 24€-47€ 91%-97%
Whey powder hydrolysate 29€-65€ 80%-90%

Can I take whey powder for dieting or muscle building?

Yes, both. On the one hand, the very high protein content in whey powder is satiating and on the other hand, it consumes a higher number of calories for processing in the body than, for example, carbohydrates do. It is not for nothing that there is a wide range of low- or even no-carb diets (also called ketogenic diets) in which the majority of the nutrients consumed during the diet consist of proteins.

Since muscle itself consists largely of proteins, they are one of the most important building blocks for building muscle in conjunction with appropriate strength training. The rapid absorption of whey powder in the body in particular makes it an ideal companion after any strength training session. This is when the building blocks are needed most urgently.

For muscle building, protein is not only important but essential.

Is whey powder an alkaline food?

Yes, whey powder is a strongly alkaline food and ideal for any alkaline diet.

What is the effect of whey powder on lactose intolerance?

Due to its very high lactose (milk sugar) content, whey powder can cause digestive problems in lactose intolerant people.

What alternatives are there to whey powder?

Casein powder is an alternative that has the effect of being absorbed more slowly by the body. Especially in the sports sector, it should be seen as a complementary product to whey protein powder. Whey powder is taken in the morning or after training for fast absorption and casein powder in the evening for slower absorption overnight.

Vegans mainly use soy protein powder, and pure soy protein powder is lactose-free. Soy protein powder is therefore suitable for all vegetarians, vegans and people with lactose intolerance. There are also multi-component protein powders (MKP). In most cases, casein, whey protein and one or two other proteins are processed into a protein powder. The advantage of MKP lies mainly in its biological value, which means that the largest amount of the protein consumed reaches its destination through the processing.

The higher the biological value, the better a protein can be processed.

Another alternative would be to prepare the shake yourself with your own food.

Decision: What types of whey powder are there and which is the right one for you?

Basically, you can distinguish between 4 types of whey powder that are present on the market:

  • Natural whey powder
  • Powder concentrate
  • Powder isolate
  • Powder hydrolysate

The biggest differences between the respective types relate to the composition of the ingredients. The respective proportion of proteins, carbohydrates (including lactose!) and fats is individual to each variation. In addition, there are major differences in price. In the following section, we would like to help you decide what to buy.

What distinguishes whey powder and what are its advantages and disadvantages?

Natural whey powder is first divided into sweet or sour whey powder, whereby the nutrient profile is almost identical. Natural whey powder is mainly used for simple cooking (drinks or baking) or wellness (whey bath or whey mask).

Advantages
  • Cheapest variant
  • Balanced nutrient profile
  • Can be used for drinks, baking, bath, mask
Disadvantages
  • Less protein content
  • Slowest absorption of protein in comparison
  • Contains a lot of lactose
  • Contains a lot of carbohydrates

What distinguishes whey powder concentrate and what are its advantages and disadvantages?

A concentrate is microfiltered and consists of 70-80% protein, approx. 8% carbohydrates and 4% fats. It is also rich in glutamine and BCAAs. In comparison, whey powder concentrate contains a lot of lactose, so people with a lactose intolerance should reach for one of the types listed below. The big advantage of the concentrate over the isolate and hydrolysate is the price, which is low due to a simple production process.

Advantages
  • Very affordable
  • Balanced nutrient profile
  • Rich in glutamine and BCAA
Disadvantages
  • Less protein content
  • Slower absorption of protein
  • Contains a lot of lactose

An isolate has an extremely high purity with a protein content of over 90%. In contrast, carbohydrates and fats are represented with less than 1%. An isolate contains significantly less lactose than a concentrate and is therefore suitable for people with lactose intolerance.

Advantages
  • Very high protein content
  • Low amounts of carbohydrates and fats
  • Low lactose content
Disadvantages
  • Expensive
  • Absorption rate of protein lower than hydrolysate

What distinguishes whey powder hydrolysate and what are its advantages and disadvantages?

In the case of hydrolysate, the protein has already been split using water and can therefore be absorbed by the body much faster than an isolate or concentrate. The protein content is 80-90%. Similar to a concentrate, hydrolysate contains a high lactose content as well as glutamine and BCAAs and is priced higher than the two previous variants.

Advantages
  • Rapid absorption of protein
  • Low amounts of carbohydrates and fats
  • Rich in glutamine and BCAA
Disadvantages
  • Most expensive variant
  • Tastes bitter

Buying criteria: You can use these factors to compare and evaluate whey powders

In the following, we will show you which aspects you can use to decide between the many whey powders. The criteria you can use to compare whey proteins with each other are:

  • Composition
  • Choice of flavours
  • Size/Quantity
  • Type of packaging
  • EC Organic Regulation

In the following paragraphs, we will explain to you what is important in the individual criteria to make your purchase decision easier.

Composition

The most important criterion is the composition of the nutrient profile. Here you should ask yourself for what purpose you need the whey powder. For a whey bath or the consumption of whey powder, different conditions are set for the content of the whey powder and it would be a waste of money to use a whey protein hydrolysate for a whey bath.

Especially for muscle building it is important whether you are on a diet, lactose intolerant and at what time (e.g. before training or before going to bed) you want to consume the whey powder.

Choice of flavours

When it comes to whey powder as a food, there is an almost endless choice of flavours. From traditional chocolate to mango strawberry, pina colada or even tasteless. As trivial as this question may seem, consider this: If you go to the gym 4-5 times a week, you will drink this drink at least 4-5 times a week, as long as you drink a shake after each training session. In this case, it might make sense to buy two different flavours in a 500g pack instead of one kilo of chocolate Wheypowder, so that you don't get tired of one flavour too quickly.

Many suppliers also provide small sample packs for little money. This way, you can ideally try out three to four pleasant flavours.

Size / quantity

The first thing to consider here is: How much whey powder will you consume? Or in other words: Will you use up the whey powder before it expires? Many people overestimate their consumption or take a longer break from training and the shelf life of the whey powder expires. The number of flavours also plays a role, as already mentioned, and should be taken into account.

Each protein powder comes with a consumption recommendation, which you should roughly calculate to count the number of days you would need to consume the pack.

Always take into account training breaks, the shake for in-between meals or, if you use a recipe with whey powder, that a large amount of powder is consumed in one go. For a whey bath you should always calculate 7-8 heaped tablespoons of the powder and roughly estimate in your head how many baths you could take with the contents of the package.

Type of packaging

The type of packaging does not only mean the visual purpose of the packaging, but rather a functional one. The role of the size and shape of a package is particularly important in small flats. As a rule, the whey protein powder is shipped in bag or can form. Whereas the former can still be stowed flexibly in corners and small rooms and takes up less space as the contents decrease, the can takes up more space, regardless of whether it is full or almost empty.

EC Organic Regulation

Do you pay special attention to organic products? As a customer, you can be sure that, for example, no genetic engineering or species-appropriate animal husbandry is used. You should always look for the state organic seal, which reflects compliance with the EC Organic Regulation.

Facts worth knowing about whey powder

Is it better to take whey powder with milk or water?

It all depends on what is important to you. For example, the taste, the functionality of the whey powder, the cost factor and much more. Below we have compiled some advantages and disadvantages of milk and water. Advantages and disadvantages of water:

Advantages
  • Better absorption of protein
  • Less calories
  • Less expensive
  • More flexibility
Disadvantages
  • Less nutrients
  • Doesn't taste good to many

Advantages and disadvantages of milk:

Advantages
  • More nutrients
  • Plus protein
  • Tastes creamier and better
Disadvantages
  • More calories
  • More costly
  • Milk has to be taken along additionally

When is the best time to take whey powder?

Whey protein powder is best taken in the morning after getting up or directly after training, as the body has used up its nutrient stores and needs new building blocks for regeneration and muscle building.

How much protein does my body need?

This question can only be answered precisely if you know all the factors, including age, sporting activity and body weight. Roughly, the amount of protein needed can be summarised as follows.

Target group Protein amount per kg body weight
Non-athletes 1g-1.2
Recreational athletes 1.2g-1.8g
Competitive athletes 2g-2.5g

What is the shelf life of whey powder?

As a rule, whey powder has a shelf life of about one year, but always check the expiry date, which must be clearly marked on all packaging. PS: Should you ever get past the expiry date, you shouldn't have to throw it away straight away.

Many people are of the opinion (and so are we in the editorial team) that whey powder has a much longer shelf life than stated on the packaging. It is usually only the active ingredients that deteriorate slightly.
