About the EAA (9 Essential Amino Acids)
Product Details
What are Essential Amino Acids?
Essential Amino Acids (EAAs) are a group of nine amino acids that the body cannot synthesize on its own,
making them a critical part of your diet. Animal proteins are the best EAA sources, including eggs, chicken,
fish, beef, and dairy products. They are complete proteins as they contain all nine essential amino acids.
Some plant proteins contain all nine, such as quinoa, tofu, and spirulina. However, most other plant
proteins lack certain amino acids. Taking EAA supplements can help ensure individuals obtain all the
nutrients their bodies need.
These amino acids are vital for numerous physiological processes. They are the building blocks of proteins
and crucial for muscle growth, tissue repair, and numerous metabolic functions. Unlike non-essential amino
acids, individuals must obtain EAAs from food sources or supplements, as the body cannot produce them
internally. They include histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine,
tryptophan, and valine.
What Do the Nine Essential Amino Acids Do?
H istidine : Histidine is a precursor to histamine, an
important neurotransmitter involved in immune response, digestion, and sleep-wake cycles. Histidine is
also crucial for maintaining the myelin sheaths that protect nerve cells.
I soleucine : Isoleucine is a branched-chain
amino acid (BCAA) that is fundamental for muscle metabolism and energy production. It also helps
with hemoglobin synthesis, immune function, and regulating blood sugar levels.
L eucine : Another BCAA, leucine is particularly important for stimulating
muscle protein synthesis. It activates the mTOR pathway, which is essential for promoting muscle growth
and repair. Leucine also helps regulate blood sugar levels and supports wound healing.
L ysine : Lysine is vital for synthesizing protein,
