What are amino acids?
Amino acids are organic compounds that serve as building blocks for proteins in the body. They are fundamental for many biological processes, including muscle growth, metabolism, and tissue repair. There are a total of 20 amino acids used by the body, nine of which are essential and must be obtained through diet because the body cannot produce them itself. Amino acid supplements can be a way to ensure adequate intake, especially for individuals with increased needs, such as during exercise or certain dietary regimens.
Benefits & uses
Amino acids are often used as supplements to complement protein intake and support the body's functions. Here are some common uses:
- Support for muscle building and recovery after exercise
- Supplementing protein in vegetarian or vegan diets
- Support during increased protein needs, for example during physical activity or ageing
How to choose the right amino acids
Choosing the right amino acids depends on your individual needs and goals. Here are some tips to consider when buying amino acids online:
- Identify the purpose: Do you want amino acids for training or as a dietary supplement?
- Essential vs non-essential: Essential amino acids must be obtained through diet, while non-essential can be produced by the body.
- Form and dosage: Amino acids come in powder, capsules, and tablets. Choose the form that best fits your daily routine.
- Quality and purity: Ensure the product comes from a reliable manufacturer with a clear ingredient list.
- Specific amino acids: Some amino acids like BCAA (branched-chain amino acids) or L-glutamine have particular uses.

Popular variants
There are several types of amino acids commonly used as supplements, tailored to different needs:
- Essential amino acids (EAA): Contain all the amino acids the body cannot produce itself.
- BCAA (branched-chain amino acids): Consist of leucine, isoleucine, and valine, and are popular among people who exercise.
- L-Glutamine: An amino acid found in high concentrations in muscles and often used for recovery.
- L-Arginine: Can be used to support the body's natural processes.
- Other free amino acids: Such as L-Tyrosine, L-Lysine, and L-Citrulline, which have specific roles in the body.
Frequently asked questions about amino acids
What is the difference between amino acids and protein?
Amino acids are the individual building blocks that together form proteins. Proteins are long chains of amino acids linked in a specific order that determines the protein's function.
Can I take amino acids without exercising?
Yes, amino acids can be taken as a supplement regardless of physical activity, for example to complement the diet or in cases of specific nutritional needs. However, it is important to follow the recommended dosage.
How do I know which amino acid I need?
It depends on your goals and any dietary restrictions. Essential amino acids and BCAA are commonly used for support during training, while other amino acids can be chosen based on specific needs. Please consult a health specialist if you are unsure.
