Protein Fusion is a multi-source protein that combines 4 high-quality milk protein sources with different absorption rates. Whey hydrolysate, isolate and concentrate provide a rapid supply, while the more slowly digested calcium caseinate ensures a sustained supply of amino acids. As a result, the body receives amino acids both immediately after consumption and gradually over the following hours. The protein is also enriched with the DigeZyme® enzyme complex and the LactoSpore® bacterial strain. The result is a comprehensive protein suitable not only immediately after training, but also between meals or as an addition to food.
Not all proteins are absorbed at the same rate, and that is important to know. Protein Fusion by GymBeam deliberately combines fast- and slower-digesting protein sources, helping to supply your muscles with amino acids both immediately after physical activity and for a further 4 hours. It is based on a carefully selected blend of 4 milk proteins with high biological value, which make up 87–95% of the formula, depending on the flavour. It contains no cheap soy or other plant-based protein. We have also added the DigeZyme® enzyme complex and the Bacillus coagulans bacterial culture LactoSpore®. The result is more than just another ordinary protein powder: it is a thoughtfully formulated aid to help you pursue your sports 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 30 g serving therefore provides 22.2–23.1 g of protein and 5.2 g of BCAAs, including 2.4 g of leucine.
Whey protein on its own, whether it is a concentrate, isolate or even hydrolysate, raises blood amino acid levels rapidly and sharply, but only for a relatively short time: 1–3 hours, depending on how it is processed. However, when you combine it with casein, the supply of amino acids to your tissues is significantly extended, up to 4 hours. That is precisely the point. That is why we have combined four carefully selected milk proteins in one product. Here is the result:
-
Whey protein hydrolysate (WPH): The fastest start to 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, making amino acids available in the blood almost immediately. It was an obvious choice because it provides an ideal stimulus for initiating muscle protein synthesis.
-
Whey protein isolate (WPI): Pure, fast-absorbing whey 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 produces a very pure, fast-absorbing protein source with an excellent amino acid profile rich in branched-chain amino acids (BCAAs), including the essential amino acid leucine.
-
Whey protein concentrate (WPC): A dependable 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 helps it retain naturally occurring bioactive proteins such as beta-lactoglobulin, alpha-lactalbumin and immunoglobulins. WPC remains a fast-absorbing protein source and stands out among whey proteins for its pleasantly milky taste and creamy consistency.
-
Calcium caseinate: The fourth member of the team, providing slow and steady release
Casein is the other main protein in cow’s milk, accounting for roughly 80% of all milk proteins. For this blend, we chose calcium caseinate, a form that dissolves well and does not form lumps. It digests considerably more slowly than whey, making it the slowest-absorbing component of the blend. It releases amino acids gradually, long after the whey has done its job. It acts as an anti-catabolic guardian for your muscles and is particularly useful during longer intervals between meals.
DigeZyme® is a patented multi-enzyme complex from Sabinsa. It contains 5 enzymes that help digest 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 lactose, the sugar found in milk
- lipase, which breaks down fats
- cellulase, which breaks down fibre in the form of cellulose
One serving (30 g) of 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 viability and stability in the product.
One serving (30 g) contains 1 billion CFU (colony-forming units).
Whey protein alone rapidly raises amino acid levels in the blood after consumption, but they then quickly return to baseline. This is ideal immediately after training, but several 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 bloodstream gradually. Their levels therefore remain high enough to stimulate muscle protein synthesis for longer. What is the result?
- Immediate anabolic stimulus: Whey hydrolysate and isolate stimulate muscle protein synthesis almost immediately.
- Strong intermediate phase: Whey concentrate, the most abundant component of the blend, maintains a steady supply of amino acids.
- Longer-lasting anti-catabolic protection: Calcium caseinate takes over from whey concentrate and continues to maintain elevated amino acid levels in the blood.
A similar principle was also confirmed by studies by Reidy (2013)1 and Kanda (2016)2. The Reidy (2013)1 study compared whey protein alone with a blend of proteins absorbed at different rates (whey, casein, soy). The blend was able to maintain elevated amino acid levels in the blood for longer and supported muscle protein synthesis at least as effectively as whey alone.
Who is Protein Fusion suitable for?
1. Strength athletes and gym-goers who want to maximize muscle growth and give their bodies the best nutrition after training and between main meals. Muscles cannot grow without protein. For 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 they participate in CrossFit and HYROX, team sports such as ice hockey and football, or endurance sports such as cycling and running. When training volume and frequency are high, adequate protein intake is essential for 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 useful to know that protein contributes to the maintenance of normal bones.5
3. People following a weight-loss diet or using GLP-1 products. A weight-loss diet carries the risk of reduced intake of a range of essential nutrients, including protein. Reduced energy intake can lead to a loss of muscle mass, and increasing your intake of high-quality protein is one way to help prevent it. Protein also contributes to the growth and maintenance of muscle mass.5
4. People aged 65 and over. Anabolic resistance increases with age, meaning the body generally becomes less effective at using dietary protein to rebuild muscle. A high-quality protein source combining several types of 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, significantly more than the commonly recommended 0.83 g of protein per kilogram of body weight for adults.7
5. Women seeking a firmer physique. Protein certainly will not make you excessively muscular. Instead, it provides your body with important building blocks for developing a firm, toned physique. By helping you feel full, it can also make it easier to manage cravings for sweets.
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 oatmeal, smoothies or pancake batter. These foods are typically high in carbohydrates and contain relatively little protein. Adding protein makes them more balanced meals while conveniently increasing your protein intake.

I ordered it based on a good experience with the vanilla flavor of Just Whey, which tastes genuinely pleasant. This protein, however, is its exact opposite. Just the smell alone makes your stomach turn, not to mention the taste. I’ll try to pass it on to someone for whom this won’t be such a problem.
