4Life® NanoFactor®


• Description: a conditionally essential amino acid, the most abundantamino acid in the body.

• Health benefits: primary source of energy for the various cells of the immune system, maintains the health of the mucosa of the gastrointestinal tract and inhibits muscle wasting in critically ill patients.

• Sources & dosage: plant and animal proteins such as beef, pork and poultry, milk, yogurt, ricotta cheese, cottage cheese, raw spinach, raw parsley, and cabbage. Typical dietary intake of L-glutamine is 5 to 10 grams daily.

• Deficiency symptoms: diarrhea, villous atrophy, mucosal ulceration, increased intestinal permeability, and intestinal necrosis.

• Side effects: people with kidney disease, liver disease, or Reye's syndrome should not take glutamine.
Glutamine is important to an optimal immune system since several types of important immune cells rely on it for energy. Research also suggests that when glutamine levels fall, other systems may be affected, particularly the digestive system. Glutamine levels may be depleted by injury, surgery, infection or prolonged stress.  Each tablet contains 500 mg of L-Glutamine

Glutamine (molecular weight: 146.15 g/mol) is one of the 20 amino acids encoded by the genetic code. Glutamine is a non-essential amino acid, meaning it can be produced by the body and is involved in a variety of metabolic processes. Glutamine has recently been re-classified as a conditionally essential amino acid. This means that while the body can make glutamine, under extreme physical stress the demand for glutamine exceeds the body's ability to synthesize it. During times of stress glutamine reserves are depleted and need to be replenished through supplementation. Glutamine is one of the three amino acids involved in glutathione synthesis. Glutathione, an important intracellular antioxidant and hepatic detoxifier, is comprised of glutamic acid, cysteine, and glycine.

Glutamine functions, uses, and health benefits - Glutamine is involved in more metabolic processes than any other amino acid. Glutamine is converted to glucose when more glucose is required by the body as an energy source. Glutamine also plays a part in maintaining proper blood glucose levels and the right pH range. It serves as a source of fuel for cells lining the intestines. Without it, these cells waste away. It is also used by white blood cells and is important for immune function. Glutamine 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. Glutamine regulates the expression of certain genes, including those that govern certain protective enzymes, and helps regulate the biosynthesis of DNA and RNA. Construction of deoxyribonucleic acid (DNA) is dependent upon adequate amounts of glutamine. Glutamine increases the body's ability to secrete human growth hormone (HGH). HGH assists in metabolizing body fat and helps to support new muscle tissue growth. Glutamine is important for removing excess ammonia. In the process of picking \fs20softlineup ammonia, glutamine donates it when needed to make other amino acids, as well as sugar, and the antioxidant glutathione. The glutamic acid-glutamine interconversion is of central importance to the regulation of the levels of toxic ammonia in the body, and it is thus not surprising that when the concentrations of the amino acids of blood plasma are measured, glutamine is found to have the highest of all.

The health benefits of glutamine include immune system regulation, nitrogen shuttling, oxidative stress, muscle preservation, intestinal health, injuries, and much more. Supplemental l-glutamine can be helpful in the treatment of arthritis, autoimmune diseases, fibrosis, intestinal disorders such as ulcerative colitis, peptic ulcers, and connective tissue diseases. Glutamine is the primary source of energy for the various cells of the immune system, including T cells and macrophages. Strenuous exercise, viral and bacterial infections, and stress and trauma in general cause glutamine depletion that starves the immune cells. Glutamine helps to protect the lining of the gastrointestinal tract known as the mucosa. Glutamine supplementation maintains the health of the mucosa (inner wall) of the gastrointestinal tract and inhibits muscle wasting in critically ill patients. Glutamine has been shown to enhance the ability of medications to kill cancerous growths. Many people with cancer have abnormally low levels of glutamine. Glutamine protects the liver during toxic chemotherapy, during acetaminophen toxicity, and following a severe inflammatory injury to the liver. Glutamine is used to protect the lining of the small and large intestines from damage caused by chemotherapy or radiation. Glutamine can aid in healing stomach ulcers and prevent inflammation of the stomach that is caused by chronic use of nonsteroidal anti-inflammatory medications.

Individuals with advanced stages of human immunodeficiency virus (HIV) often experience severe weight loss (particularly loss of muscle mass). Glutamine combined with antioxidants or other nutrients may help people with HIV to gain weight. Digestion and normal metabolic function of the intestines are dependent upon adequate amounts of glutamine. Glutamine helps to protect the lining of the gastrointestinal tract known as the mucosa. L-glutamine levels have been found to be decreased in endurance athletes who train too often and at high intensity. Athletes with a strenuous training schedule may be able to reduce the risk of infections by supplementing with glutamine.

4Life® NanoFactor® Glutamine Primesupplies an added source of support for healthy immune cell function, especially during times of increased stress. Glutamine is an amino acid that serves as a major source of fuel for immune cells.Glutamine is continually needed and used by the immune system but reserves can become depleted by additional everyday stress, such as exercising and training for athletic events, keeping up with busy day-to-day life, or struggling with various health problems. Glutamine Prime is formulated with the rich energy source of glutamine to help optimize immune cell function.
