Amino acids were discovered to be some of the first molecules at the origin of life, they are essential to the proper functioning of our organs and act at the very heart of our cells. Amino Acids are natural compounds produced by the body and obtained from diet.
There are 20 different kinds of amino acids that exist, 11 are found in our diet and made by our bodies. There are 9 « essential » Amino Acids because the body cannot produce these amino acids, hence the supplementation of amino acids, the essence of life, is important for our well-being.
The 9 « essential » Amino Acids
Abundant in hemoglobin, it promotes the production of red blood cells. It also favors copper assimilation, and as a precursor of glutamate, it provides a source of muscular energy.
A branched-chain amino acid involved in the maintenance of intellectual performance during intense prolonged exercises and favors muscle protein synthesis after workouts.
This branched-chain amino acid triggers protein synthesis, particularly the renewal of muscle cells. It is also involved in the maintenance of intellectual performance during prolonged physical efforts. Studies suggest that it promotes muscle mass development.
A precursor to carnitine and stimulates the physiological production of the growth hormone (GH).
A sulfur-containing amino acid possessing antioxidant properties. It is a precursor to creatine, carnitine, and S-adenosyl methionine (SAM). Studies suggest that methionine is involved in the development of muscle mass.
Precursor to tyrosine, it also plays a role in the feeling of satiety (fullness) and in muscle development.
Amino acid, strictly indispensable, since the body cannot in any circumstances synthesize it.
Amino acid precursor of serotonin, melatonin, and vitamin B3. Its diffusion in the central nervous system is favored when the circulating BCAA quantity is lowered following a physical exercise. The increasing serotonin results in the induction of sleep and reduces appetite.
A branched-chain amino acid involved in the maintenance of intellectual performance during prolonged physical efforts. It promotes protein synthesis in muscle after exercise.
The 11 amino acids that can be produced by our bodies
Involved with memory, mental fatigue, and participates in the protection against free radicals produced by glutathione, an important controlling element of excess free radicals (antioxidant activity).
It is the most important amino acid released in large quantities by muscles during muscle breakdown. It participates in the restoration of energy reserves by promoting gluconeogenesis.
A conditionally essential amino acid, it is precursor for the synthesis of other amino acids and creatine. It participates in the synthesis of nitrogen monoxide (NO), an important part of blood pressure regulation. It plays an important role in eliminating (detoxifying) ammonia from the body. Furthermore, it stimulates secretion functions of the pancreas and also contributes to the regulation of insulin production. Lastly, it promotes the release of the growth hormone (GH).
This amino acid is dependent on aspartic acid. It is one of the precursors of DNA and RNA synthesis which constitutes the <genetic blueprint > of our cells.
Essential to detoxification processes, it also acts as a neurotransmitter. It participates in the synthesis of ATP, the energy source to all cells.
A conditionally essential sulfur-containing amino acid, it represents an important part of amino acids present in skin, hair, and nails. Cystine is the stable form of cysteine.
A conditionally essential amino acid, it is the most abundant found in muscles. It is a source of energy recruited for the Krebs cycle. As a precursor of ornithine and citrulline, it plays an important role in metabolic detoxification of urea. Glutamate is a neurotransmitter and precursor of gamma- aminobutyric acid (GABA). This amino acid plays a vital role in supplying energy to immune cells and also promotes the maintenance of the body’s natural defenses when subjected to intense physical activity. Lastly, it is a component of glutathione (antioxidant activity).
A conditionally essential amino acid, it is a substrate for the synthesis of creatine. It is also one of the precursors of DNA and RNA synthesis, the « genetic blueprint » of our cells. Lastly, it is a component of glutathione, an important part of controlling excess free radicals (antioxidant activity).
A conditionally essential amino acid, it is necessary for the stability of the collagen triple helix. Thus, it is present in increase quantities in the skin, and also in cartilage and bone. It is therefore abundantly present in the skin, as well as in cartilage and bone.
Amino acid involved in the biosynthesis of cysteine and phospholipids of the brain, necessary for cognitive functions.
A conditionally essential amino acid, it is a precursor for catecholamine (adrenaline), melanin (skin pigmentation), and thyroxine (thyroid hormone). Associated with a high-protein diet, it can favor weight loss. It also has a positive effect on balancing the nervous system and particularly stress management.
