4Life Research Announces
New Discovery
NanoFactor™Natural Intuition "NanoFactor™ extract is 4Life' s patent-pending extract of nanofractions from cow colostrum. Armed with the natural intuition from nanofractions, your immune cells know when to act, how to act, and when to rest".

Transfer Factors™ are molecules in a weight class between 3.500 - 12.000 Daltons that help the immune system recognize, respond and remember threats to our health. Although scientists have known that smaller molecules than transfer factors existed within cow colostrum, their significance in terms of immune activity have been unknown until now.

After two years of research, 4Life reports indicate that molecules in a weight range between 250 - 3.000 Daltons play an important regulatory roll in the immune system.

4Life extracted and concentrated this patent-pending nanofraction, under the proprietary name, NanoFactor™. Combining NanoFactor with  Transfer Factor E-XF™ extract 4LIfe has produced 4Life Transfer Factor® Tri-Factor™ Formula, the most comprehensive approach to immune system support available today.

"I don't know of another company in our category," said 4Life Chief Scientific Officer Calvin McCausland, Ph.D. "In 2004, we were the first company to combines transfer factors from cow colostrum and chicken egg yolks. In 2005, we introduced RioVida®, the world's only transfer factor beverage. Now, the discovery of new immune activity in nanofractions. When it comes to scientific innovation, there's simply no comparison to 4Life. "

4Life Transfer Factor, Transfer Factor Trifactor Plus, and RioVida are now fortified with the new Tri-Factor Formula's. "We're taking Tri-Factor Formula's to the world because no other product represents such a unique and indispensable opportunity to enhance our quality of life," remarked 4Life President Steve Tew.

4Life founder David Lisonbee remarked; "At the end of the day, our customers can rest assured that 4Life will stay far ahead of the curve in the area of science, service, and success."

4Life Research, global leader in the development, production, and distribution of Transfer Factor immune support products, continues to post growth in more than 40 countries around the world.


• 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.
