The 9 essential amino acids

Essential amino acids are those that cannot be produced by the body and must therefore be received from food. The creation of proteins, enzymes, hormones, and other vital components depends on these essential amino acids, which are crucial for the development and maintenance of a healthy body. The 9 essential amino acids Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Threonine, Tryptophan, and Valine are necessary for good health and well-being.

Histidine

Histidine is essential for human growth. It is also essential for nervous system maintenance and a metabolite of the neurotransmitter histamine. Histidine’s primary function is the metabolization and control of heavy metals like iron, copper, molybdenum, zinc, and manganese.

Isoleucine

Isoleucine is involved in the production of hemoglobin, the healing of damaged tissue, and the control of blood sugar and energy levels.

Leucine

Leucine contributes to the regulation of blood-sugar levels, growth and repair of muscle and bone tissue, growth hormone production and wound healing. Leucine is important for protein synthesis and many metabolic functions.

Lysine

Lysine is essential for calcium absorption and healthy muscle and nervous system function. Lysine additionally assists in collagen and carnitine production.

Methionine

Methionine is one of two amino acids that contain the element sulfur. Methionine produces several important molecules in your body. Sulfur-containing molecules have a variety of functions, including the protection of your tissues and maintaining proper function of your cells.

Phenylalanine

Phenylalanine is needed for the synthesis of protein. It is also an important precursor of L-Tyrosine. L-Tyrosine can increase levels of dopamine, adrenaline and norepinephrine, which means it could help improve memory and performance.

Threonine

Threonine is necessary for the synthesis of glycine and serine. It assists in collagen, elastin, and muscle tissue production. Threonine works together with aspartic acid and methionine to promote fat metabolism in the liver.

Tryptophan

Tryptophan improves energy levels and mood. It is also an important precursor to melatonin, enzymes and structural proteins.

Valine

Valine aids in all types of muscle tissue recovery, repair, and growth and is often used by endurance athletes. It is a very popular weight loss supplement because it has been shown to decrease appetite.
