What is an EAA Supplement?
EAA stands for Essential Amino Acids, in other words essential aminos. It supplies all 9 aminos that your body cannot produce on its own. You have to get them through food or dietary supplements.
They are the building blocks of proteins and important for building and maintaining muscle mass. As a supplement, you get them in various forms: powder, capsules, or tablets. Most athletes go for the powder form because it is easy to dose flexibly.
The 9 essential amino acids
Your body needs these 9 essential aminos:
- L-Leucine - The most important for muscle protein synthesis
- L-Isoleucine - Part of the BCAAs
- L-Valine - Together with leucine and isoleucine, they form the BCAAs
- L-Lysine - Essential amino acid
- L-Methionine - Plays a role in metabolism
- L-Phenylalanine - Building block for other substances in the body
- L-Threonine - Essential amino acid
- L-Tryptophan - Essential amino acid
- L-Histidine - One of the nine essential amino acids
Your body cannot produce these 9 on its own. That's why intake through food or supplements is important, especially with intense sport and fitness.
EAA, BCAA, or Whey Protein?
A common question: Which is better, EAA, BCAA, or whey protein? Here's the comparison:
| Supplement | Contains | Ideal for |
| EAA | All 9 essential aminos | Complete supply, training, dieting |
| BCAA | Only leucine, isoleucine, and valine | During training, endurance |
| Whey Protein | Complete amino profile | Protein intake across the day |
EAA vs BCAA: EAAs contain all 9 essential aminos, BCAAs only 3 (leucine, isoleucine, valine). For a complete supply, they are the better choice. BCAAs alone are not enough for muscle building.
Combining EAA + whey: This is possible but not automatically necessary: whey protein already contains all 9 essential aminos. What matters is your total protein intake, not a fixed order around training.
EAA dosage and intake
Dosage: Serving sizes differ from product to product; for EAA Xtreme it is 20 g. The recommended intake on the pack is what counts. Pay attention to the amino acid profile, especially the L-Leucine content.
Timing: When should you take them?
Before, during or after training: whatever fits your daily routine. A particular time is no proof of an extra benefit; the recommended intake of the product is what counts.
Tip: On rest days, you can take them in the morning to supply your body with essential amino acids.
EAA powder or capsules?
| Form | Advantages | Ideal for |
| Powder | Flexible dosing, cheaper per serving | Athletes who like shakes |
| Capsules | Practical on the go, no taste, easy to take | Anyone who likes it uncomplicated |
| Tablets | High dose per unit, long shelf life | Anyone who wants to take high amounts easily |
Our bestsellers: The EAA Xtreme from GN Laboratories impresses with a top amino acid profile and delicious taste. If you like it more intense, go for the Berserk EAA from Gods Rage with bold flavors.
Who are essential amino acids useful for?
Essential amino acids are suitable for various target groups:
Strength athletes: For muscle building and maintaining muscle mass. They supply the building blocks for new muscles and muscle tissue.
Endurance athletes: For long sessions, if you want to drink extra amino acids on the go. The supplement can also be drunk during sport.
When dieting: If you eat less, check whether your protein intake drops as well. An EAA supplement can add to your intake, but on its own it does not guarantee that you keep your muscle.

EAAs provide all 9 essential amino acids that your body needs to build muscle, maintain muscle mass and regenerate. They are the building blocks of proteins and are important for athletes and fitness enthusiasts.
Should I take EAA every day?
You can take EAAs daily. On training days before, during or after sport. On non-training days in the morning for a good supply. The intake depends on your goal and your diet.
Which is better, BCAA or EAA?
EAAs are the better choice. They contain all 9 essential amino acids, BCAAs only 3 (leucine, isoleucine, valine). For complete muscle building you need all 9, BCAAs alone are not enough.

No. BCAAs only contain 3 of the 9 essential amino acids. Your body needs all 9 for muscle protein synthesis, so EAAs are the more complete choice.
