What is EAA?
EAA stands for Essential Amino Acids — the nine amino acids that the human body cannot synthesize on its own. They must be obtained from food or supplements. The nine essential amino acids are:
- Leucine
- Isoleucine
- Valine
- Lysine
- Methionine
- Phenylalanine
- Threonine
- Tryptophan
- Histidine
EAA supplements contain all nine essential amino acids in a single product, providing a more complete amino acid profile compared to BCAA, which contains only three of them.
How they work
Amino acids are the building blocks of proteins. The human body requires 20 different amino acids to synthesize proteins. Nine of these are essential — the body cannot produce them and they must come from external sources.
A deficiency in any essential amino acid can affect normal bodily function. This is why ensuring adequate intake through diet is important. EAA supplements offer a convenient way to complement amino acid intake.
Composition and properties
EAA supplements do not have specific EFSA (European Food Safety Authority) approved health claims for amino acid combinations. Therefore, we describe only composition-related facts here:
- Amino acid profile: contains all nine essential amino acids
- Complete profile: unlike BCAAs, which contain only three amino acids, EAA provides all nine essential amino acids
- Essentiality: all nine amino acids must be obtained from external sources
Important note: health claims such as "increases muscle mass", "speeds up recovery", or "improves protein synthesis" must not be made for EAA supplements, as these are not approved by EFSA for amino acid blends.
How to take
EAA powder is typically mixed with water or another beverage. Capsules are swallowed with water. Always follow the recommended serving size on the product packaging.
Timing of intake is a matter of personal preference. EAAs are often consumed during training or around training sessions, but the specific timing depends on your personal routine.
EAA powders are often flavored, making them convenient to consume during workouts.
Who should use them
EAA supplements are used by a variety of people:
- Active trainers who want to ensure adequate intake of all essential amino acids
- Athletes who prefer a more complete amino acid profile compared to BCAAs
- Vegetarians and vegans whose diet may not always provide sufficient amounts of all essential amino acids
- People looking for a low-calorie source of amino acids
Essential amino acids are naturally found in many protein sources: meat, fish, eggs, dairy products, and certain plant-based foods. It is advisable to consult a healthcare professional before starting any new supplement.
Frequently asked questions
What is the difference between EAA and BCAA?
EAA contains all nine essential amino acids, while BCAA contains only three: leucine, isoleucine, and valine. EAA therefore provides a broader amino acid profile.
Does EAA replace a protein shake?
An EAA supplement is not intended to replace protein powder. These are different products with different properties. EAA provides amino acids without the additional protein, carbohydrates, and fats that protein powder may contain.
Is EAA suitable for vegans?
Many EAA products are produced through plant-based fermentation and are suitable for vegans. Always check the product label.
Can EAA powder be mixed with other supplements?
Yes, EAA powder can typically be mixed with water, juice, or a sports drink. Capsules are swallowed with water. Follow the usage instructions for each product.
When is the best time to take EAA?
No definitive optimal time has been established. Take EAAs according to your preference and the product usage instructions.
How many essential amino acids are there?
The human body has nine essential amino acids: leucine, isoleucine, valine, lysine, methionine, phenylalanine, threonine, tryptophan, and histidine.
