Everything you need to know about essential amino acids (EAAs)!

Amino acids are the building blocks of life. Among them there is a special group known as essential amino acids or EAAs. These play a crucial role in the body and are essential for various biological processes.

What are Essential Amino Acids?

Amino acids are organic compounds that form proteins. There are a total of 20 amino acids, nine of which are considered essential because the body cannot produce them itself and therefore they must be obtained through the diet. These nine EAAs are: leucine, isoleucine, valine, lysine, methionine, phenylalanine, threonine, tryptophan and histidine (considered essential in children and certain conditions).

Functions of essential amino acids in the body

Protein biosynthesis

EAAs play a crucial role in protein synthesis. They serve as building blocks for the formation of proteins needed to build and repair tissue, muscles, enzymes, hormones and other important biological molecules in the body.

Energy production

Certain EAAs can be used as fuel during times of increased energy demands. In particular, the BCAA (branched-chain amino acids) - leucine, isoleucine and valine - can be used by the body as a source of energy, especially during intense physical activity or in times of stress.

Regulation of metabolic processes

EAAs are also involved in the regulation of various metabolic processes. They support the function of enzymes and help maintain a healthy metabolic balance.

Sources of Essential Amino Acids

Essential amino acids must be consumed through diet as the body cannot produce them independently. Foods such as meat, fish, eggs, dairy products, legumes, nuts and seeds are rich in EAAs. A balanced diet that includes a variety of protein sources can help meet essential amino acid needs. You should supplement EAAs, especially if you are physically active. Your body needs a higher number of essential amino acids, especially when building muscle and strength training. We recommend EAAs in the flavor iced tea lemon or mango from Athletic Supplements.

Importance of EAAs for health

Muscle building and recovery

EAAs are of particular interest to athletes and fitness enthusiasts because they play an important role in muscle building and recovery after exercise. They can help support muscle maintenance during dieting and improve recovery after intense exercise.

Cognitive functions and mood

Tryptophan, an essential amino acid, is a precursor to serotonin, a neurotransmitter that plays an important role in regulating mood, sleep and cognitive function. A lack of tryptophan could negatively impact these areas.

General well-being and immunity

Essential amino acids help maintain a strong immune system and support overall well-being. They play a role in tissue repair, hormone production, and other vital functions in the body.

Safety and dosage

For most people, a balanced diet is sufficient to meet the need for essential amino acids. In some cases, such as certain dietary conditions or intense physical activity, supplemental EAAs may be considered. However, it is important to respect the dosage and the advice of a professional to avoid overdose.


Essential amino acids are crucial for numerous biological processes in the body. Their intake through a balanced diet is important for muscle building, metabolic health, cognitive function, immune system and general well-being. Consciously choosing foods rich in essential amino acids can help provide the body with these important nutrients and support optimal health.
