Protein Fusion is a multi-source protein, which combines 4 high-quality dairy protein sources with different absorption rates. Fast absorption is provided by whey hydrolysate, isolate and concentrate, while a longer-lasting supply of amino acids is provided by the more slowly digested calcium caseinate. This provides the body with amino acids both immediately after consumption and gradually over the next few hours. The protein is also enriched with the DigeZyme® enzyme complex and the LactoSpore® bacterial strain. The result is a comprehensive protein blend, ideal not only immediately after a workout, but also between meals or as an addition to meals.
Not all proteins are absorbed at the same rate, and that is important to know. Protein Fusion by GymBeam is designed to combine fast- and slower-digesting protein sources, supplying your muscles with amino acids both immediately after physical activity and for a further 4 hours. At its core is a carefully selected blend of 4 milk proteins with high biological value, which make up 87–95 % of the entire formula, depending on the flavour. You will find no cheap soy or other plant-based protein in it. We have also enriched it with the DigeZyme® enzyme complex and the bacterial culture Bacillus coagulans LactoSpore®. The result is more than just another ordinary protein supplement: it is a thoughtfully formulated partner for your sport and fitness goals, whatever they may be.
Protein Fusion contains 74–77 g of protein per 100 g of product, depending on the flavour you choose. One 30g serving therefore provides 22,2–23,1 g of protein, 5,2 g of BCAA, including 2,4 g of leucine.





Whey protein alone, whether a concentrate, isolate or even hydrolysate, raises blood amino acid levels rapidly and sharply, but only for a relatively short period of 1–3 hours, depending on how it is processed. However, when you combine it with casein in the right way, the supply of amino acids to your tissues is significantly extended to up to 4 hours. That is exactly the point. This is why we have combined 4 carefully selected milk proteins in one product. Here is the result:
-
Whey protein hydrolysate (WPH): The fastest onset of protein synthesis
This is a special type of whey protein that enzymes deliberately break down during production into short peptide chains of amino acids. As a result, it is absorbed extremely quickly, and amino acids become available in the blood almost immediately. It was an obvious choice here, as it provides an ideal stimulus to kick-start muscle protein synthesis.
-
Whey protein isolate (WPI): Pure, fast-absorbing whey protein without compromise
During production, it undergoes several types of filtration (microfiltration and ultrafiltration), which remove most of the milk fat and lactose. There is nothing wrong with either, but removing them results in a very pure, fast-absorbing protein source with an excellent amino acid profile rich in branched-chain amino acids (BCAA), including the essential amino acid leucine.
-
Whey protein concentrate (WPC): A reliable choice
This makes up the largest share of Protein Fusion. It is produced using the gentle CFM method (cross-flow microfiltration), in which microfiltration takes place at low temperatures. This allows it to retain naturally occurring bioactive proteins, such as beta-lactoglobulin, alpha-lactalbumin and immunoglobulins. WPC is still classed as a fast-absorbing protein source and stands out among whey proteins for its pleasantly milky flavour and creamy texture.
-
Calcium caseinate: The fourth member of the team for slow, gradual release
Casein is the other main protein in cow's milk, accounting for approximately 80 % of all milk proteins. For this blend, we chose calcium caseinate, a form that dissolves well without forming lumps. It is digested significantly more slowly than whey protein, making it the slowest-digesting fraction in the blend. Its amino acids are released gradually, long after the whey protein has done its job. It acts as an anti-catabolic guardian of your muscles, especially useful during longer gaps between meals.
DigeZyme® is a patented multi-enzyme complex from Sabinsa. It contains 5 enzymes involved in digesting the main components of food.
- alpha-amylase, which breaks down carbohydrates in the form of starches
- protease, which breaks down proteins
- lactase, which breaks down the milk sugar lactose
- lipase, which breaks down fats
- cellulase, which breaks down fibre in the form of cellulose
One serving (30 g) of the protein contains 80 mg of the DigeZyme® enzyme complex.
LactoSpore® is a patented ingredient from Sabinsa containing the bacterium Bacillus coagulans MTCC 5856 (now classified as Heyndrickxia coagulans). The bacteria are present in spore form, which significantly increases their longevity and stability in the product.
One serving (30 g) contains 1 billion CFU (colony-forming units).

Drinking whey protein on its own quickly raises blood amino acid levels, but they then rapidly return to baseline. This is great immediately after training, but a few hours later, the stimulation of muscle protein synthesis is significantly weaker.
Protein Fusion works differently. It combines fast- and slow-digesting proteins, so amino acids are released into the blood gradually. Their levels therefore remain high enough to stimulate muscle protein synthesis for longer. What is the result?
- Immediate anabolic stimulus: Whey protein hydrolysate and isolate kick-start muscle protein synthesis almost immediately.
- A strong middle phase: As the largest component of the blend, whey protein concentrate maintains a steady supply of amino acids.
- Longer anti-catabolic protection: Calcium caseinate takes over from whey protein concentrate and continues to maintain elevated blood amino acid levels.
A similar principle was also confirmed by the studies by Reidy (2013)1 and Kanda (2016)2. The Reidy (2013)1 study compared whey protein alone with a blend of proteins with different absorption rates (whey protein, casein and soy protein). The blend was able to maintain elevated blood amino acid levels for longer and supported muscle protein synthesis at least as effectively as whey protein alone.

Who is Protein Fusion suitable for?
1. Strength athletes and gym-goers who want to maximise muscle hypertrophy and give their body the best both after training and between main meals. Muscles cannot grow without protein. To achieve this goal, scientific studies recommend a daily intake of 1,6–2,2 g of protein per kilogram of body weight.3
2. Athletes with demanding training or competition schedules, whether in CrossFit and HYROX, team sports such as hockey and football, or endurance sports such as cycling and running. With a high training volume and frequency, adequate protein intake is key to protecting muscles and supporting their recovery. Athletes are generally advised to consume 1,2–2,0 g of protein per kilogram of body weight.4 Physical activity also places demands on the musculoskeletal system. It is therefore good to know that protein contributes to the maintenance of normal bones.5
3. People on a weight-loss diet or taking GLP-1 products. A weight-loss diet carries the risk of a reduced intake of a range of essential nutrients, including protein. Reduced energy intake can lead to muscle loss, and one way to help prevent this is to increase your intake of high-quality protein. Protein also contributes to the growth and maintenance of muscle mass.5
4. People aged 65+. So-called anabolic resistance increases with age, and the body typically becomes less efficient at using dietary protein to repair muscles. A high-quality, multi-source protein is therefore an ideal choice for older athletes and active seniors who want to build and maintain muscle mass. According to the latest studies, they need at least 1,0–1,2 g of protein per kilogram of body weight6, which is significantly more than the 0,83 g of protein per kilogram of body weight generally recommended for adults.7
5. Women aiming for a firmer physique. Protein certainly will not make you look bulky and masculine. Instead, it gives your body important building blocks for developing a firm, toned physique. By promoting satiety, it also helps you manage cravings for sweets more effectively.
6. Anyone who wants a convenient way to meet their daily protein needs. Enjoy it as a tasty shake with water or milk, or add it to porridge, smoothies or pancake batter. These are typically carbohydrate-rich foods without much protein, so adding protein makes them more complete and balanced while conveniently increasing your protein intake.

Composition
Dosage
Mix 1 scoop (30 g) with 250 ml of water. Take 1–2 times a day according to your total protein intake needs.
After training.
Fast-digesting whey proteins kick-start muscle growth and recovery immediately, while slower-digesting caseinate sustains muscle protein synthesis for longer. What does this mean in practice? You do not need to worry about rushing to have your next meal straight after training.Between meals. The combination of fast- and slower-digesting proteins maintains a steady supply of amino acids even during longer gaps between meals. This makes it useful both when cutting and when building muscle mass.
Before bed. Slower-digesting caseinate is beneficial during the longer period without food while you sleep.
To add protein to meals. You can add the protein powder to porridge, pancakes, smoothies, yoghurt or dough for homemade baked goods. The possibilities are endless.

I ordered it based on my positive experience with the Just Whey vanilla flavor, which tastes truly pleasant. However, this protein is its exact opposite. Even the smell alone is nauseating, let alone the taste. I will try to pass it on to someone who will not mind it as much.Translated by Google
