How to Choose a Protein? Comparison of True Whey, Just Whey, and Other GymBeam Bestsellers

Dozens of containers, different colors, different prices. How to navigate it all? Choosing the right protein can sometimes seem like quite a big science. When you browse the offerings, you quickly realize that not all proteins are created equal. They differ in composition, processing method, and whether they are completely pure or enriched with other substances. So, how do you choose the best one for you?

We have prepared an overview of proteins from the GymBeam portfolio to help you navigate them. We will show you which protein makes sense for weight loss, muscle gain, sensitive digestion, and answer other burning questions about proteins.

What is a protein supplement?

Protein (protein powder) is a concentrated source of protein obtained from animal (whey, casein) or plant sources, which serves to support muscle growth, regeneration, maintenance of healthy bones, and other bodily processes.

What are the benefits of protein powders?

Protein powders are excellent sources of protein, which are among the essential macronutrients. It doesn’t matter whether you are an athlete and train regularly or are just trying to maintain a balanced diet, protein is vitally important for you. We obtain it primarily from food, but during periods when our need is higher – for example, during training, weight loss, or greater physical exertion – it can be challenging to cover the intake solely through food. This is when protein supplements make sense, serving as a practical way to supplement protein alongside a regular diet. ^[1]

You have several options. If you want protein from milk, you can choose from three basic forms of whey protein. Other variants include proteins from casein, vegan plant proteins, or potentially beef proteins.

Forms of Whey Protein

1. Whey Concentrate (WPC – Whey Protein Concentrate)

Whey concentrate is the most popular type of protein with an excellent price-to-quality ratio. It typically has a 70–80% protein content.

• Absorption: moderately fast, takes approximately 2–3 hours
• Key benefit: excellent price-to-quality ratio, contains beneficial milk fats and other bioactive components in addition to protein
• Ideal for: regular athletes, beginners, daily protein supplementation (e.g., True Whey protein)

2. Whey Isolate (WPI – Whey Protein Isolate)

Whey isolate is a purer form of protein resulting from additional filtration of concentrate. It has minimal lactose and a higher protein content, typically 80% or more.

• Absorption: fast due to lower fat and carbohydrate content
• Key benefit: minimal fat, lactose content, and very high protein content
• Ideal for: people with mild lactose intolerance, athletes on a diet and in the cutting phase (e.g., Pure IsoWhey product)

3. Whey Hydrolyzate (WPH – Whey Protein Hydrolysate)

Whey hydrolyzate is a form of whey concentrate or isolate whose proteins are broken down into smaller pieces. This allows for faster absorption and makes it very easily digestible. The protein content ranges from approximately 70–90%. ^[2]

• Absorption: fastest of all types of whey proteins – thanks to hydrolysis, amino acids appear in the blood within minutes
• Key benefit: excellent digestibility without burdening digestion, even after an intense workout
• Ideal for: elite athletes and people with very sensitive digestion (e.g., HydroFue protein)

How are GymBeam whey proteins made?

Whey concentrates and isolates are produced using the gentle CFM method (Cross Flow Microfiltration). This ensures that proteins retain their valuable components, including protein fractions such as immunoglobulins or lactoferrin.

Hydrolyzates, on the other hand, are created from concentrates or isolates, where proteins are broken down into shorter chains by enzymatic hydrolysis. This makes them more rapidly digestible than regular proteins.

We offer all these types of proteins. It goes without saying that proteins in the GymBeam portfolio have a transparent composition, meet strict European food standards, and undergo regular testing to ensure their quality and safety.

4. Anabolic Whey – GymBeam

Anabolic Whey is a multi-component protein made from whey concentrate and casein, designed for people who want to support muscle mass growth and have higher demands for protein and energy intake. It stands out with the addition of creatine, dextrose, and glutamine peptides, which is a more bioavailable form of the amino acid glutamine. This makes it excellent for athletes who want to boost their overall physical performance.

• Type of protein: multi-component protein from whey concentrate (WPC) and casein
• What sets it apart: multi-component composition supplemented with creatine monohydrate, glutamine peptides, and dextrose (a simple, rapidly absorbed sugar)
• Protein content: 19 g of protein per serving

Clear Whey IsoFue mixes with water to create a clear, fruity drink. If you crave some refreshment after your workout and also want to replenish protein, this protein is an ideal choice. In summer, you can take it up a notch, as it tastes great chilled, even with ice. You can even prepare excellent mixed drinks with it. You can choose from several fruity flavours sweetened with sucralose.

7. HydroFue – GymBeam

HydroFue is a premium whey hydrolyzate with excellent absorbability and digestibility. It is a specialised protein that targets performance and regeneration rather than universal daily use. Thanks to its rapid absorption, it more effectively supports proteosynthesis (MPS, the creation of new muscle proteins).

• Type of protein: whey hydrolyzate
• What sets it apart: enzymatically hydrolysed protein with very rapid absorption, supplemented with digestive enzymes, vitamins, and minerals
• Protein content: up to 22.6 g of protein per serving
• Lactose content: very low lactose content
• Content of special substances: DigeZyme^® digestive enzyme complex, bromelain, vitamins B6, E, zinc, and magnesium
• Suitable for: performance and strength athletes, athletes in demanding training periods, people with more sensitive digestion
• Not suitable for: people looking for a cheap protein or a protein with a delicious taste (due to hydrolysis, it naturally has a more bitter taste), for beginners without specific requirements
• When to use: after training or during periods of increased training load

HydroFue is produced by hydrolysis, where proteins are partially broken down into shorter amino acid chains, allowing for faster absorption into the bloodstream. This also makes it very easy to digest, does not burden the stomach even after an intense workout, and proteins reach the muscles faster within minutes.

Since it is a hydrolyzate, it typically has a slightly bitter taste. The shorter protein chains formed by cleavage are naturally bitter. However, in HydroFue, this taste is successfully masked by delicious flavours sweetened with sucralose. In terms of price, it belongs to the premium category.

8. Micellar Casein – GymBeam

Micellar Casein is a slow-absorbing protein that, unlike whey protein, delivers protein to the body gradually over 5–6 hours. This is why it is also known as night protein and is ideal, for example, when you won’t be eating for a long time or want to support regeneration during sleep. ^[3]

• Type of protein: micellar casein
• What sets it apart: very slow absorption, gradual protein release
• Protein content: up to 20.5 g of protein per serving
• Lactose content: medium
• Content of special substances: no added functional ingredients
• Suitable for: strength athletes, active people who have longer breaks between meals
• Not suitable for: individuals with significant lactose intolerance, vegans
• When to use: before bed or as a filling snack during the day

Micellar casein naturally has a thicker, creamy consistency and can keep you full for longer. That’s why it’s suitable not only as an evening protein but also for porridges, puddings, or sweet desserts. If you’re looking for a protein that will sustain you for several hours and help supplement protein when you don’t plan to eat, micellar casein is exactly the type that makes sense.

9. Vegan Blend – GymBeam

Vegan Blend is a multi-component plant-based protein that combines pea, rice, and hemp protein. It is designed for vegans and everyone who prefers plant-based protein sources. Thanks to a well-thought-out combination of several sources, it has a balanced amino acid profile, also containing the limiting amino acids lysine and methionine in the correct ratio. You can therefore use it daily.

• Type of protein: multi-component plant-based protein from pea isolate, rice concentrate, and hemp protein
• What sets it apart: has a complete amino acid spectrum thanks to a well-thought-out combination of plant proteins
• Protein content: up to 23 g of protein per serving

• Content of special substances: natural fibre content, no added functional ingredients
• Suitable for: vegans, vegetarians, people with lactose intolerance or cow’s milk protein allergy, active people preferring a plant-based diet
• Not suitable for: those who expect the taste and texture typical of whey proteins
• When to use: after training, during the day, or as part of meals

Vegan Blend is the right choice if you are looking for a vegan protein with a complete spectrum of essential amino acids in an ideal ratio that plant proteins can offer. Moreover, it is gluten-free and lactose-free, making it a great solution even if you avoid these ingredients in your diet. As for taste, although it naturally has a slightly earthy texture typical of plant proteins, it mixes well with water and plant-based milk. It also offers several flavours sweetened with sucralose, as well as an unflavored variant without sweeteners. Price-wise, it falls into the mid-range category.
