What are Essential Amino Acids?
Essential amino acids, also known as EAAs, are amino acids that the body cannot produce on its own. Therefore, they must be obtained through diet or supplements.
Essential Amino Stack contains all 8 essential amino acids in free form: leucine, lysine, phenylalanine, isoleucine, valine, histidine, threonine, and methionine. This approach differentiates it from a BCAA product, which only contains three amino acids.
EAA vs. BCAA: What's the Difference?
BCAAs are three specific amino acids: leucine, isoleucine, and valine. EAAs include a broader group of essential amino acids, including BCAAs.
Therefore, Essential Amino Stack is a more complete formula than a classic BCAA. If you are looking only for leucine, isoleucine, and valine, you can compare this option with BCAA Powder. If you prefer a complete essential amino acid profile, EAA may be a better fit.
Essential Amino Stack for before, during, or after training
The powder format allows you to prepare an amino acid drink that is easy to consume around your workout. You can use it before, during, or after training, depending on how you organize your routine.
It can also be suitable if you train on an empty stomach, if you prefer a light drink during the session, or if you want an alternative to amino acid capsules. The Unflavored version can be mixed with other supplements or drinks, while the fruity flavors work well with cold water.
Available Flavors
Essential Amino Acids is available in several flavors:
- Tropical Fruit
- Fruit Punch
- Green Apple
- Piña Colada
- Raspberry
- Unflavored
Availability may vary by stock. The Unflavored version is interesting if you want to mix it with another drink or a product that already has flavor.
How to take Essential Amino Acids
Mix 11g, approximately 1 scoop, with 250ml of water or your preferred beverage. Shake well in a shaker until the powder dissolves.
You can take it before, during, or after training, according to your preferences and routine. Do not exceed the recommended daily dose.
Food supplements should not be used as a substitute for a varied and balanced diet.
