What is EAA ?
EAA stands for “essential amino acids.” These are the amino acids that your body cannot produce by itself, so you must get them from food or supplements.
There are nine essential amino acids humans need: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan, and valine.
EAAs are the building blocks of proteins in your body. Proteins — made from amino acids — are used to repair tissues, build muscle, make enzymes and hormones, support immune function, and more.
Supplements with EAAs are popular among people who work out, because they can help:
Boost muscle protein synthesis (i.e. help build and repair muscle).
Improve recovery after training, reduce muscle soreness, and help with endurance and performance.
Support body functions beyond muscles — like metabolism, immune system, and general protein / tissue maintenance.
That said — if you already eat a balanced, protein-rich diet (meat, poultry, eggs, dairy or a variety of plant proteins), you might already get enough EAAs naturally.
Many nutrition experts treat EAA supplements as a “convenience boost” rather than a must-have: useful when diets or training demand is high, but not strictly necessary for everyone.
I found a listing titled “Lion Nutrition‑EAA 285 g – 30 Serv Blue Berry”.
That suggests:
The product is a powdered EAA supplement under the “Lion Nutrition” brand.
A container size 285 g, advertised to give ~30 servings.
So each “serving” is presumably the portion you mix with water (common for amino‑acid / pre/intra/post workout powders).
People use such EAAs around workouts — before, during, or after — depending on goals such as muscle building or recovery.
Supplements labelled “EAA” or “EAA + BCAA” can vary widely: the exact amounts of each amino acid may differ and affect effectiveness.
If your diet already covers enough amino acids and protein, extra EAAs might not provide a huge benefit (though they might still help if you exercise heavily).
As with any supplement: check you do not exceed safe amounts, ensure hydration (some EAA formulas include electrolytes), and — if you have medical conditions — consider consulting a doctor or nutritionist.
