Yamamoto® Nutrition Essential AMINO POWDER - Food supplement based on essential amino acids
Essential AMINO Powder is a matrix composed of essential amino acids obtained through vegetable fermentation . Essential amino acids (EAA – Essential Amino Acid) are those that the human body is not able to synthesize autonomously in quantities sufficient to satisfy its needs, and which must therefore be necessarily ingested through the diet . It is important to remember that EAAs also include branched chain amino acids, known as BCAAs (Branched Chain Amino Acid), and that amino acids are the organic molecules that our body uses to form Protein .
What is an essential amino acid supplement for? When nutrition alone is not sufficient to reach needs or when the quantity consumed of certain foods is reduced, EAA supplements are certainly a valid aid in providing the body with everything it needs for protein synthesis.
Essential AMINO is characterized by the presence of an l-leucine, l-isoleucine and l-valine ratio of 2:1:1, therefore with a greater presence of leucine : this amino acid is in fact fundamental for protein synthesis . Furthermore, the 2:1:1 ratio between amino acids is the one most present in nature. Essential AMINO also contains all 8 EAAs in an optimal ratio to maximize bioavailability and minimize the production of nitrogenous waste.
What are essential amino acids (EAA) for humans? Per human beings (adults), there are 8 essential amino acids, and specifically we are talking about:
Lysine : present mainly in milk, soy, beef, but almost absent in cereals, serves for the formation of carnitine and vitamin B3. Per athletes it is able to speed up post-workout recovery.
Tryptophan : found in milk and dairy products, eggs, legumes, meat and fish. It is an important amino acid in protein synthesis, and represents the starting point in the synthesis of serotonin and niacin.
Phenylalanine : is found in most animal and vegetable Protein, therefore in meat, offal, fish, eggs and also in brown rice. It is involved in many metabolic processes, also used as a "structural building block" of Protein, and participates in the formation of thyroid hormones.
Threonine : found mostly in corn, soybeans, eggs, mushrooms, cod, pork, lamb, rabbit and veal. It is one of the amino acids most easily missing from the vegan diet. It is a constituent of antibodies, and therefore plays a fundamental role in maintaining the immune system.
Methionine : Found in dairy products, egg whites, sesame seeds, Brazil nuts, cod and soy Protein. Methionine is the basis of the production of carnitine and cysteine, as well as creatine, taurine and vitamin B12. It has a chelating action on some heavy metals and if present in sufficient quantities acidifies the pH of the urine.
Leucine : Milk, corn, chicken and eggs are the main food sources of this amino acid. It plays an important role at a muscular level, and is a source of alternative energy in case of intense sporting activity.
Isoleucine : found mainly in corn, potatoes, chicken, eggs, peanuts, bresaola, lamb. It is closely linked to glucose needs (it is in fact defined as a glucogenic and ketogenic amino acid), prevents the catabolism of structural Protein and promotes recovery after prolonged effort.
Valine : the following are rich in: egg white powder, soy Protein, Spirulina algae, dairy products and dairy products. It plays important roles especially in tissue reconstruction.
Of these 8 EAAs, the last 3 described (Leucine, Isoleucine and Valine) are called BCAAs (from the English Branched Chain Amino Acid), i.e. branched amino acids, united by the presence of a lateral branched chain.
