Essential Amino Acids (EAA Complex)

Muscle building & fitness

Function & benefits

The nine amino acids the body cannot make and must get from food; they provide the complete building blocks for muscle protein synthesis and outperform BCAA alone because they supply every amino acid needed to complete it.

Dosage & how to use

Recommended dose	10–15 g dissolved in water
Best time to take	During or after training, or between meals
Frequency	1–2 times daily

Best forms to choose

Fast-absorbing free-form EAA powder, sugar-free and leucine-enriched.

Important warnings

Not needed if you eat plenty of complete protein such as chicken, eggs and whey

People with advanced kidney or liver failure should adjust the dose with their doctor

Drug interactions

Safe with most medicines; take them two hours apart from levodopa in Parkinson's disease, because amino acids compete with it for absorption.
