Non Essential Amino

Non-essential amino acids are those that can be synthesized by the body and are different from essential amino acids that are obtained from food. The term 'nonessential' does not infer that those amino acids are any less important however. The body is simply capable of creating them on its own; therefore it is not necessary for it to attain them from an outside source. These nonessential amino acids serve many functions to create optimal health. Glycine, proline or hydroxyproline in collagen peptide are both non-essential amino acid.

Already rich in 9 essential amino acids, Säräng Peptide also comes in abundance of 9 non essential amino acids. In largest quantity order : aspartic acid, serine, glumatic acid, proline, arginine, tyrosine, cystine, glycine and alanine. 


Aspartic Acid

Plant protein, especially that found in sprouting seeds, contains an abundance of aspartic acid. Aspartic acid is interconvertible with asparagine, and therefore the two amino acids have many functions in common.

Major functions : increases stamina ; good for fatigue and depression, and plays a vital role in metabolism ; helps protect the liver by aiding the removal of ammonia; involved in DNA and RNA metabolism; involved in immune system function by enhancing immunoglobulin production and anti-body formation.


Serine can be synthesized in the body from glycine but this process requires the presence of sufficient amounts of vitamins B3 and B6 and folic acid. Serine is required for the metabolism of fat, tissue growth and the immune system as it assists in the production of immunoglobulins and antibodies. One of the 3 most important glycogenic amino acids, the others being alanine and glycine. However, too-high serine levels in the body may have adverse effects on the immune system.

Major functions: critical in maintaining blood sugar levels; boosts immune system by assisting in production of antibodies and immunoglobulins; needed for the proper metabolism of fats and fatty acids, the growth of muscle; a component of brain proteins and the protective myelin sheaths that cover nerve fibers; required for growth and maintenance of muscle.

Glutamic Acid

Glutamic amino acid is important in the metabolism of sugars and fats, and aids in the transportation of potassium into the spinal fluid and across the blood-brain barrier. The brain can use glutamic acid as fuel. Glutamic acid can detoxify ammonia by picking up nitrogen atoms, in the process creating another amino acid, glutamine. The conversion of glutamic acid into glutamine is the only means  by which ammonia in the brain can be detoxified.

Major functions: helps stop alcohol and sugar cravings; increases energy; accelerates wound healing and ulcer healing; plays major role in DNA synthesis; helps to correct personality disorders and is useful in treating childhood behavioral disorders; used in the treatment of epilepsy, mental retardation, muscular dystrophy, ulcers, and hypoglycemic coma, a complication of insulin treatment for diabetes; a component of folate (folic acid), a B vitamin that helps the body break down amino acids.


Proline can be synthesized from glutamic acid and does not require dietary sources. The main precursor to proline is glutamate. Secondary precursor to proline is ornithine (minor amino acid).

Major functions: critical component of cartilage, and hence health of joints, tendons and ligaments. It works with vitamin C to promote healthy connective tissue; involved in keeping heart muscle strong; works in conjunction with vitamin C in keeping skin and joints healthy; improves skin texture by aiding in the production of collagen and reducing the loss of collagen through the aging process. 


Arginine is abundant in protamines and histones - both proteins associated with nucleic acids. Arginine is used by the body to make nitric oxide, a substance that relaxes blood vessels.


Arginine is required in muscle metabolism - maintaining the nitrogen balance, and helping with weight control since it facilitates the increase of muscle mass, while reducing body fat. This amino acid can be produced in the body; however, in newborn infants, production may not occur quickly enough to keep up with requirements. It is therefore deemed essential early in life.

Major functions : essential for normal immune system activity; necessary for wound healing; necessary for production and release of growth hormone; assists in healing through collagen synthesis; decreases size of tumors; necessary for spermatogenesis.


Tyrosine is abundant in insulin as well as the enzyme papain and can be synthesized from the amino acid phenylalanine in the body. Tyrosine is important to overall metabolism. It is a precursor of adrenaline and the neurotransmitters norepinephrine and dopamine, which regulate mood and stimulate metabolism and the nervous system. Requires pyridoxal-5-phosphate (P5P) a form of vitamin B6 to be converted into norepinephrine. P5P deficiency will lower norepinephrine levels, even if Tyrosine levels are normal. Precursor to thyroxine and growth hormone. Eeffective antidepressant for norepinephrine-deficient depressions. Tyrosine is preferred over phenylalanine, which is also a precursor to all of the above neurotransmitters. Phenylalanine is one step removed from the metabolic process, and can aggravate high blood pressure. Supplemental L-tyrosine has been used for stress reduction, and research suggests it may be helpful against chronic fatigue and narcolepsy. It has been used to help individuals suffering from anxiety, depression, low sex drive, allergies, and headaches, as well as persons under going withdrawal from drugs. It may also help people with Parkinson's disease.

Main Functions: acts as a mood elevator; a lack of adequate amounts of tyrosine leads to a deficiency of norepinephrine in the brain, which in turn can result in depression; also acts as a mild antioxidant; suppresses the appetite; helps to reduce body fat; aids in the production of melanin (the pigment responsible for skin and hair color) and in the functions of the adrenal, thyroid, and pituitary glands; increases energy, improves mental clarity and concentration.


These two amino acids are closely related; each molecule of cystine consists of two molecules of cysteine joined together. Cysteine is very unstable and is easily converted to L-cystine; however, each form is capable of converting into the other as needed. This amino acid is formed from L-methionine in the body.

Major functions : antioxidant; protective against radiation, pollution, ultraviolet light and other causes of increased free radical production; Cystine or the N-acetyl form of cysteine (NAC) may be used in place of L-cysteine. NAC aids in preventing side effects from chemotherapy and radiation therapy; because it increases glutathione levels in the lungs, kidneys, liver, and bone marrow, it has an anti aging effect on the body-reducing the accumulation of age spots; natural detoxifier, Cysteine helps to detoxify harmful toxins and protect the body from radiation damage; essential in growth, maintenance, and repair of skin; key ingredient in hair.


Glycine retards muscle degeneration by supplying additional creation, a compound that is present in muscle tissue and is utilized in the construction of DNA and RNA. It improves glycogen storage, thus freeing up glucose for energy needs. Glycine is essential for the synthesis of nucleic acids, bile acids, and other nonessential amino acids in the body. It is used in many gastric antacid agents.

Major functions: part of the structure of hemoglobin; one of the two main inhibitory neurotransmitters (the other being GABA) and as such can help prevent epileptic seizures; part of cytochromes, which are enzymes involved in energy production; inhibits sugar cravings; involved in glucagon production, which assists in glycogen metabolism; necessary for central nervous system function and a healthy prostate; has been used in the treatment of manic (bipolar) depression, and can also be effective for hyperactivity; high concentrations of glycine are found in the skin and connective tissues, it is useful for repairing damaged tissues and promoting healing.


One of the simplest amino acids with respect to molecular structure and is one of the most widely used in protein construction.

Major functions : important source of energy for muscle; primary amino acid in sugar metabolism; boosts immune system by producing antibodies; major part of connective tissue.


It is the most abundant free amino acid found in the muscles of the body. Because it can readily pass the blood-brain barrier, it is known as brain fuel. It assists in maintaining the proper acid/alkaline balance in the body, and is the basis of the building blocks for the synthesis of RNA and DNA. It promotes mental ability and the maintenance of a healthy digestive tract. Glutamine has the highest blood concentration of all the amino acids. Glutamine is found in large amounts in the muscles and is readily available when needed for the synthesis of skeletal muscle proteins. Because this amino acid helps to build and maintain muscle, supplemental glutamine is useful for dieters and bodybuilders. More important, it helps to prevent the kind of muscle wasting that can accompany prolonged bed rest or diseases such as cancer and AIDS. This is because stress and injury (including surgical trauma) cause the muscles to release glutamine into the blood stream. In fact, during times of stress, as much as one third of the glutamine present in the muscles may be released. As a result, stress or illness can lead to the loss of skeletal muscle. If enough glutamine is available, however, this can be prevented.

Major functions: important glycogenic amino acid, meaning that it is essential for helping to maintain normal and steady blood sugar levels; essential to gastrointestinal function; provides energy to the small intestines. The intestines are the only organ in the body that uses Glutamine as its primary source of energy; helpful in the treatment of arthritis, autoimmune diseases, fibrosis, intestinal disorders, peptic ulcers, connective tissue diseases such as polymyositis and scleroderma, and tissue damage due to radiation treatment for cancer.
