Amino Acids: Building Blocks for Muscles, Bones, and More
Amino acids are the building blocks of proteins—that is, protein molecules—and are therefore involved in many processes, such as maintaining muscle mass andbone health.There are 20 different amino acids found in proteins, which can be divided into three groups:essential, semi-essential, and non-essential amino acids.
The body cannot produce essential amino acids on its own. They must therefore be obtained through diet. These include, for example, tryptophan, lysine, methionine, and phenylalanine. Although the body can produce semi-essential amino acids—such as arginine, glycine, glutamine, histidine, and tyrosine—from essential amino acids, in certain situations—such as during growth, exercise, or pregnancy—the amounts produced are insufficient. In these cases, they must be obtained through the diet. The body can produce non-essential amino acids, such as alanine and serine, on its own.
Amino acids are often taken in the form of capsules or as vegan protein and collagen powders when following a low-protein diet or when there is an increased need for them. Glutathione, which is composed of the three amino acids cysteine, glutamine, and glycine, is also commonly used to detoxify the body.

WHAT OUR CUSTOMERS SAY
What types of amino acids are there?
All proteins in our body are made up of different amino acids. The individual amino acids are linked together to form a chain. The length and exact composition vary greatly among different proteins. If a specific amino acid is missing, the protein cannot be formed properly and loses its function. That is why it is important for the body to have an adequate supply of all amino acids.As mentioned above, there are a total of 20 amino acids that occur in proteins and are therefore also referred to as proteinogenic, i.e., protein-forming, amino acids. They can be divided into essential, semi-essential, and non-essential amino acids.| Intake through food is | Amino acids |
|---|---|
|
essential |
Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, Valine |
|
semi-essential |
Arginine, Asparagine, Cysteine, Glutamine, Glycine, Histidine, Proline, Tyrosine |
|
non-essential |
Alanine, aspartic acid, glutamic acid, serine |
Amino Acids — Functions
Proteins are found in all of our cells. Because of their diversity, they can perform a wide variety of functions. Their length alone—that is, the number of amino acids—can vary greatly. For example, some proteins contain no more than 10 amino acids and are called peptides, while others consist of 100 to as many as 30,000 amino acids.
Proteins can be classified into:
- Structural proteinsare found primarily in connective tissue, bone, and cartilage, as well as in muscles, and are very important for maintaining the body's structure—collagen, for example.
- Examples of immune proteinsinclude the antibodies produced by our immune system, which is responsible for fighting pathogens.
- Transport proteinsare divided into two categories: transmembrane proteins and plasma proteins. Transmembrane proteins are found in biological membranes through which substances can be transported. Plasma proteins are found in the blood, where they transport substances such as lipids, hormones, and oxygen and regulate blood clotting.
- Motor proteins, such as actin and myosin, are found in muscle tissue, which must always be ready for muscle contractions.
Proteins are particularly well known for promoting the maintenance and growth of muscle mass as well as healthy bones.
Daily Protein Requirements
An adult’s daily protein requirement depends heavily on their individual metabolism. Typically, this is estimated at0.9 to 1 g of protein per kg of body weight. Under conditions of increased mental and physical strain—such as during stressful situations or physical activity—protein requirements increase by 0.3 to 1 g per kg of body weight, depending on the severity of the strain.
For highly active athletes, a protein intake of about1.4 to 2 g of protein per kgof body weightis recommended, since during extreme, prolonged physical exertion, up to 10% of the body’s own proteins are utilized forenergy production. Essential amino acids, in particular, play a major role for strength athletes such as bodybuilders. The more of these that are consumed, the more protein synthesis in the muscles is stimulated, as proteins promote not only the maintenance but also the growth of muscle mass. Forambitious strength athletes, protein requirements can even rise toas much as 3 g per kg of body weight.
The Benefits of Plant-Based Protein Powders and Capsules
In general, animal and plant products contain the same amino acids, but in different amounts and compositions.
Animalprotein sources typically have a high content of essential amino acids and are therefore similar to the proteins in the human body. This allows them to be easily converted into the body’s own proteins, which corresponds to a high biological value. However, they are considered less healthy because they contain more saturated fatty acids than plant-based foods and also cause the body to produce much more uric acid.
Plant-basedprotein sources, on the other hand, are also rich in vitamins, dietary fiber, and phytochemicals. To increase the biological value of plant-based protein sources, these sources can be intelligently combined. They are then just as easily digestible as animal protein. For example, the productPro Amino Spezialfeatures an optimally balanced combination of rice and pea protein. In addition to an exceptionally high protein content of over 80%, rice and peas complement each other perfectly. Rice primarily provides methionine and cysteine, while peas provide arginine and lysine.Pro Protein Vegan, on the other hand, contains a perfect blend of pea and fava bean protein plus the added amino acid methionine, thereby achieving a biological value of 100. Pro Amino MA8even contains all eight essential amino acids—also from plant sources—in ideal proportions. It precisely matches the human amino acid profile and can therefore be fully utilized for building body protein.
Collagen, the quintessential structural protein and the skin’s main protein—which provides firmness and elasticity—gradually breaks down starting at age 30. It consists primarily of the amino acid glycine, which the body can produce on its own but often does so in insufficient quantities for various reasons. OurPro Collagen Vegancontains the vegan Type 1 collagen alternative VeCollal®, which provides the necessary amino acids and stimulates collagen synthesis in the skin.
FREQUENTLY ASKED QUESTIONS
I'm not trying to build muscle—do I still need protein?
Yes. Protein isn't just important for athletes. It helps maintain muscle and bone mass, strengthens the immune system, and plays a role in many metabolic and recovery processes—even in everyday life, without a specific focus on building muscle.
Amino acids or protein powder: Which is better?
Protein powder provides complete protein, which the body first breaks down into amino acids. Free amino acids, on the other hand, are immediately available and can be used particularly quickly for protein synthesis. The choice depends on your personal needs.
I have a protein intolerance. Can I still take amino acids?
Yes, because amino acids are already in a broken-down form and do not put a strain on the digestive tract the way whole protein does. As a result, they are usually well absorbed even by people with protein intolerances.
When should I take amino acids instead of protein powder?
Amino acids, such as those found in our Pro Amino MA8, are ideal when the body needs these building blocks particularly quickly—for example, after a workout, during periods of stress, or when protein digestion is impaired. Protein powders, such as our Pro Protein Vegan or Pro Amino Spezial, are better suited for providing a continuous, basic supply.
What is L-arginine good for?
L-arginine supports the production of nitric oxide (NO), which dilates blood vessels and promotes blood flow. As a result, it can have a positive effect on cardiovascular health, blood pressure, and physical performance.
What are amino acids?
Amino acids are the basic building blocks of proteins and are found in all organs and tissues. The body uses a total of 20 different amino acids to produce proteins, which are needed, for example, for muscle growth and for maintaining muscle mass and healthy bones.
What are essential amino acids?
The body cannot produce these amino acids on its own and must therefore obtain them from food. There are 20 different amino acids in our bodies, eight of which are essential amino acids. These are: isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
What are non-essential amino acids?
These are amino acids that the body can produce on its own. There are 12 such amino acids in total; eight of them must be obtained from the diet during periods of increased demand and are therefore called semi-essential. The non-essential amino acids include alanine, aspartic acid, glutamic acid, and serine, while the semi-essential amino acids include arginine, asparagine, cysteine, glutamine, glycine, histidine, proline, and tyrosine.
What types of amino acids are there?
There are 20 different amino acids. The essential amino acids include isoleucine, leucine, phenylalanine, lysine, methionine, valine, threonine, and tryptophan. They must be obtained from food. The body can produce semi-essential amino acids on its own; they only need to be obtained from food when there is an increased need. These include: arginine, asparagine, cysteine, glutamine, glycine, histidine, proline, and tyrosine. Non-essential amino acids, which the body can produce in sufficient quantities on its own, include alanine, aspartic acid, glutamic acid, and serine.
What is L-arginine good for?
L-arginine, or simply arginine, is a semi-essential amino acid. An increased need for it may occur in cases of vascular disease, diabetes mellitus, chronic renal failure, or following severe injuries (Gröber, U. (2011). Micronutrients, Metabolic Tuning—Prevention and Therapy, 3rd edition).
What are the effects of amino acids?
As the building blocks of proteins, amino acids help, for example, maintain and increase muscle mass and support healthy bone formation.
What contains amino acids?
Amino acids are found in all protein-rich foods. They are present in particularly high concentrations in beef, fish, legumes, nuts, and seeds. Alternatively, you can use protein concentrates or amino acid blends.
What are proteinogenic amino acids?
"Proteinogenic" simply means "protein-producing." This means that all amino acids the body uses to produce proteins are proteinogenic and are therefore also referred to as α-aminocarboxylic acids.
