Dosage & Preparation

Mix 30g (approx. 3 tablespoons) 3K Protein powder with 300ml water or low-fat milk. First, add the liquid to the shaker. Then add a serving of 3K Protein powder and shake well for 20 - 30 seconds. For optimal results drink 1 - 2 servings daily immediately post-workout or in the evening.

Our 3K Protein tip

3K Protein contains casein protein, which keeps your body going strong for up to 7 hours. This means it is not only ideal for endurance athletes, but also for general use before bed to supply the muscles with protein overnight. For a bit of variety we recommend whey protein post-workout because it becomes available to your muscles very quickly, providing an effective, targeted supply of protein.

Average customer review

it is absolutely amazing

I was not expecting it will be so delicious! It is almost like drinking regular chocomilk :) LOVE IT! Also regarding how easy it is mixing with milk/water - 100% confirmed.

quite sweet but works pretty well for recharging

I use it within traning weeks of half marathon preparation and it helps me a lot. It is quite sweet, thoigh, but if you are mixing it with food / something more sour it tastes very good.

Loved it!

really good flavor, easy to disolve in water

3K- Vanilla

I am in love with this Protein. I've had it as shake and mixed it into smoothies and porridge and it is always delicious. The taste is awesome and the texture as well. I've been using it almost every day. I highly recommend it!


ideal for many sports


easy to prepare and actually really tasty.

really good

I tried the shake and was so surprised in a good way. So tasty

good results

With milk it´s really tasty. with water not for me. allready noticing first results ;)

first try, it´s good

I ordered for the first time at foodspring and it´s really good. I like the vanilla and strawberry one.

post workout drink

I´m really into sports and training 6 times the week so I tried lots of different wheys and I really like the cocolate one here. Tastes great, not that sweet like others and I feel good

General information about 3K Protein

3K Protein is a multi-component protein consisting of whey, casein and egg protein. Multi-component proteins are created to maximise the organic value of different protein sources. This helps achieve maximised bioavailability in the body, meaning our body can efficiently convert the protein supply into the body's own proteins.

Combining different sources of protein also creates a complex amino acid profile which is ideal for muscle building processes and an immediate supply for workouts.

Why is 3K Protein made up of whey, casein and egg protein?

Whey protein  is a part of milk protein. It represents the largest portion of our multi-component protein. Due to its immediate availability to the body it is valuable after every kind of training. 

Casein protein, is also a part of milk protein.  It is a so-called "slow" protein which takes 7 hours before it is completely metabolised by the body. Therefore Casein is ideal for providing the body with a long-lasting supply of protein. The amino acids reach the muscle cells slowly and continuously, thus supporting anabolic (muscle building) processes.

Egg protein, or egg white, is often used in the production of multi-component protein products as it significantly improves the amino acid profile. Eggs have a organic value of 100 which means they can be converted into body protein very efficiently.

Highlights of 3K Protein by foodspring

  • Cows fed exclusively on natural plant-based feed
  • 72.5% high-quality whey protein, 20% casein protein and 1% egg protein
  • High organic value for maximised absorption in the body
  • High proportion of essential amino acids for muscle building

3K Protein is ideal for muscle building

The amino acids contained in 3K Protein are important for muscle building processes. The best known essential amino acids that are relevant for building muscle are the BCAAs. The Branched Chain Amino Acids (BCAAs: leucine, isoleucine and valine) become available to the body very quickly and can be metabolised directly in the muscle.

Non-essential amino acids are also very important for intense workouts. They promote muscle growth and maintain muscle definition. A study of 24 athletes published in the Nutrition Journal found that supplementing your diet with multi-component proteins with a high whey protein content can significantly increase not only muscle mass, but also strength and energy.

Furthermore, the casein content in 3K Protein is perfect for putting a stop to catabolic processes (processes which break down muscle) which occur as a result of a lack of a protein supply over an extended period of time. Casein protein supplies the body with a continuous flow of protein elements for up to 7 hours, which it can use for building and repair processes.

The effects of 3K Protein

In the context of the effects of the 3K Protein the term organic value comes up a lot.

The organic value indicates how well the body can convert proteins from food into the body's own proteins. Nutritionist Karl Thomas believed that egg contained the highest possible organic value and gave it the value 100 as a benchmark for all other foods.

Today, many years later, we know there are other foods with a much higher value than 100. These include whey protein with a value of 104 - 110. Multi-component proteins like 3K Protein have a high organic value of 115 - 125

The amino acid combination of the proteins in 3K Protein is perfectly balanced and can therefore be absorbed perfectly.

Who should use 3K Protein?

3K Protein is suitable for athletes who want to reap the benefits of a high organic value and multiple sources of protein in one product.

3K Protein is suitable for power athletes and endurance athletes alike because of its balanced amino acid profile and the combination of 3 sources of protein.

The correct intake of 3K Protein

3K Protein can be taken anytime because of its complex amino acid profile and the functionality of the protein combination. The protein is probably best taken first thing in the morning or after training because of its high whey content. Your body will then receive all the premium nutrients it needs during anabolic (muscle building) phases as essential amino acids, which promotes muscle growth.

The casein protein content means that 3K Protein can also be taken in the evening before you go to sleep. Casein is delivered to the muscle cells gradually and uniformly via the bloodstream and takes 7 hours to metabolise completely, providing a constant supply of nutrients overnight. Catabolic processes are prevented and protein biosynthesis (muscle building) can continue without interruption.

But the secret to long-term muscle building is not only supplying the body with protein shakes - you also have to coordinate your diet and training to achieve your physical goal. Integrating high-protein foods into your daily diet ensures that your body has a constant supply of protein elements for maintaining and building muscle.

High-protein animal products include lean meats, fish, quark and yoghurt. Plant-based sources of protein include red lentils, kidney beans, quinoa, peas and nuts. You should have a good mix of plant and animal protein sources in your diet to stay fit long-term.

Possible side effects of 3K Protein

People with severe lactose intolerance may experience stomach pains and digestive discomfort when taking 3K Protein. We recommend switching to our Vegan Protein made from peas, rice and hemp.

Fluid intake is also immensely important when increasing your protein consumption. 

If you consume 1.3 - 1.8 g of protein per kilogram of body weight per day, you should drink at least 2 - 3 litres of water. Insufficient fluid intake can result in headaches and tiredness.

Buying 3k protein online – what you need to look out for

When purchasing a multi-component protein like 3K Protein you should ensure that the protein sources are combined in such a way as to maximise the organic value. A high-quality protein should use at least two protein sources and have an organic value of at least 110. A protein of this description will have a high level of bioavailability for the body and will make an ideal supplement for training or for muscle building.

However, the most important aspect to look out for when buying a multi-component protein is the use of high-quality raw materials and certified manufacturing processes.

3K Protein by foodspring is manufactured in Germany using the finest ingredients. We use pasture milk for our proteins, a raw material with special premium features.

You can buy high-quality 3K Protein directly from our online shop.

Frequently Asked Questions
Why combine whey, casein, and egg protein?

The use of these three premium protein sources strongly enhances biological value and provides your muscles with all the essential amino acids they crave. Combining these three ingredients delivers high-quality proteins over both the short and long term. Whey provides the body with nutritious and quickly available proteins immediately after exercising. In particular, it supports fast, efficient muscle building. Casein keeps the body supplied with protein for up to 7 hours. This means that support for muscle building lasts long after a hard workout, and if you drink 3K Protein in the evening it also protects muscles from being broken down over night. Egg protein rounds out the amino acid profile of our 3K Protein and provides optimal bioavailability.

What are the advantages of steviol glycosides?

Steviol glycosides are purified extracts from the stevia plant. They make it possible to avoid unnecessary carbs and do not affect the overall calorie count. This makes steviol glycosides far superior to traditional industrially-produced sugar.

What sorts of sports is 3K Protein a good match for?

3K Protein is ideal for both muscle building and muscle definition and can be used for all sports. Whether you are looking to improve endurance, build muscle, or simply stay fit, the protein combination of high-quality whey, casein, and egg protein is an ideal, quick way to provide your body with long-term, readily available protein. With 3K Protein, the body can repair muscles and ramp up faster for the next workout.

What are the key qualities of 3K protein?

The different protein components in our 3K Protein are perfectly combined. The whey protein, which is 72.5% of the 3K Protein, is from grass-fed milk. This high-quality raw material provides your body with effective support in muscle building. Because if a cow is happy, its milk is healthy, too.
