The three types of proteins are fibrous, membrane and globular. Fibrous proteins provide structural support for cells and tissues. Membrane proteins perform a variety of functions vital to the survival of organisms. Globular proteins are somewhat water-soluble (forming colloids in water), unlike the fibrous or membrane proteins.

There are also two main categories (or sources) of proteins: animal and plant based.

Protein is the essential building material in the human body because it forms the basis of every physical cell. Protein consists of the so-called amino acids, of which there are 20 different. Of these amino acids, nine are crucial for us humans because they are essential and cannot be produced by the body. The three most essential amino acids are leucine, isoleucine, and valine also called (BCAA = Branched-Chain Amino Acids, i.e., branched-chain amino acids). The majority of our muscles are made up of proteins. It can only be built up effectively if there are enough modules. A distinction is made between vegetable and animal protein. The most significant amount of protein can be found in animal products.

For this reason, animal protein is said to be the best source for building muscle and exercising. A person who does sports or even aims to build muscle should take 1.5-2.0g of protein per kg of body weight per day as a guideline. Since it is not always easy to cover the daily requirement only through a healthy diet, more and more people are turning to protein powder.

Animal Protein

  1. Whey protein
    Whey protein is the most popular type of protein in muscle building and fitness. It is characterized by fast digestion and a high content of essential amino acids. It is also perfect in the morning or as a post-workout shake. Whey contains the three most essential amino acids leucine, isoleucine, and valine responsible for a more effective muscle building. Furthermore, the amino acids provide optimal muscle protection (this means that if the energy intake is too low, muscle mass is not reduced despite physical exertion). Whey protein is obtained from the whey that is produced in the production of cheese. It has an unusually high biological value. Whey protein, like the Multipower whey protein, is also often used for weight loss used because it is ideal as a protein-rich meal replacement. Whey is also available as an isolate, which contains less milk sugar and is therefore lactose-free. A unique manufacturing process changes the charge of the protein in the strain. Such means that the purity of a whey isolate is higher, which increases the quality.
  2. Casein
    Like whey protein, casein is a milk protein, with the only difference that the absorption process in the body takes longer. The casein molecules are more significant than those of the whey and take longer to process because they have to be broken down into smaller building blocks. Such ensures long-lasting protein intake. Many athletes drink a casein shake shortly before going to bed to provide the muscles with enough protein during the growth phase, which is why casein is often referred to as night protein. Weider offers very high-quality casein for the sleep phase, which is very popular with strength athletes.
  3. Milk Protein Isolate (Whey Protein Isolate)
    A milk protein isolate is recommended for people with lactose intolerance. Milk protein or whey isolate is obtained from whey by filtration (either microfiltration or ion filtration). It contains hardly any carbohydrates, almost no fats and no lactose ( lactose-free ). It is, therefore, very well tolerated and ideal for the time before the competition phase in bodybuilding or for muscle definition. Here, you emphasize the individual muscle groups as low in fat and carbohydrates as possible.
  4. Milk Protein Hydrolyzate (Whey Protein Hydrolyzate)
    What is the difference between isolate and hydrolyzate? An enzymatic breakdown of whey concentrate or whey isolate pre-digests this protein, and it is absorbed by the organism particularly quickly without the body having to spend energy on it. It can also be used during physical exertion, for example, during competitions, to supply proteins or amino acids to the body without wasting energy for digestion. Hydrolyzate is part of the Multipower Whey proteins and is often used in so-called amino shots, such as the Sponsor Amino 12500 ampoules. In addition to our whey protein shakes and amino-shot vials, there are also capsules with pure hydrolyzate from Inkospor.
  5. Egg Protein
    The egg protein (egg albumin) is suitable for athletes who do not tolerate dairy products well. The egg protein is made from the egg white and is characterized by its high biological value. Unlike whey, it is free of lactose, cholesterol, and purine. Due to its bitter taste, it is rarely used alone in bodybuilding products. Therefore, it is often found as a component in multi-component protein shakes to combine the different strengths of the protein types, such as in Formula 80 from Multipower.

Vegetable protein

  1. Soy Protein
    Soy protein is the most common vegetable protein in products such as the Inko Active Protein Shake, which is lactose-free. It is characterized by the nine essential amino acids’ presence and thus offers good added value for the body. Since the molecular chain of the individual amino acids is short, the body’s absorption process is concise, similar to whey. The soybean manufacturing process is complicated. Many steps are required to produce a soy protein product from the soybean that can be used by the human body.
  2. Rice Protein
    The rice protein is made from the whole grain of rice (whole grain). The protein content in the grain of rice is significantly increased by germination and fermentation. Its almost complete amino acid profile characterizes rice protein. It is, therefore, ideal for building muscle and maintaining muscle. The content of isoleucine and valine is significantly higher than that of whey. The positive side effects are also not neglected in the rice protein. It contains tons of natural forms of vitamin E, which serves as an antioxidant (defence system).
  3. Pea Protein
    The pea protein is made from the yellow peeled peas. It has 85% protein content and, like the other vegetable proteins, is an excellent protein source. The very high proportion of the amino acids arginine and lysine stands out in the pea products. Arginine helps to release growth hormones and thus promotes muscle building. The Weider Vegan Protein offers a high protein content based on pea protein.
