GABA
An essential fatty acid derivative that your body breaks down to obtain energy. Regulates your cardiovascular system and may lower blood pressure. See: GABA

Garcinia Cambogia
Fruit from India that contains Hydroxycitric Acid (-HCA), an organic acid influencing carbohydrate and fat metabolism. See: Citrimax

Garlic Extracts
Has properties of being a stimulant, anti spasmodic and antibiotic. Also helps lower total cholesterol level. See: Super Garlic

Gastrointestinal
Pertaining to the stomach, small and large intestines, colon, rectum, liver, pancreas, and gallbladder.

Genistein
A compound thought to protect you against cancer. It is found in soy based food products. It suppresses the production of stress proteins in cells, proteins that otherwise help cancer cells survive destruction by the immune system. See: Genistein Soy Isoflavone

Ginger
Ginger is derived from the tuberous rhizome (underground root) of the perennial plant Zingiber officinale of the family Zingiberaceae. Also referred to as Jamaica ginger, African ginger, or Cochin ginger, ginger has been used as a spice, condiment and flavoring agent. For nearly 2,500 years ginger has also played an important role in Asian medicine as a folk remedy to promote cleansing of the body through perspiration, to calm nausea, and to stimulate the appetite. See: Ginger

Ginkgo biloba
A herb shown to enhance mental acuity. Some research has shown that Ginkgo Biloba increases cerebral blood flow to the brain. Also, boost brain levels of adenosine Triphosphate and scavenge free radicals. Combined with ginger, gingko has also been shown too reduce stress induced anxiety. See: Ginkgo Biloba; Liquid Ginkgo Biloba

Ginseng
Highly prized Oriental herb reputed to give long life. Increases hormone production, heart rate, regulate blood pressure, improve sexual function and increase vitality.

Glandular
Supplements derived from animal glands, which may boost human gland function .
See: Thymus

Glaucoma
An eye disorder marked by increasing pressure within.

Glucosamine
Organic compound found in cartilage and joint fluid; relieves joint pain and may help in healing some joint injuries. See: Glucosamine/Chondroitin Sulfate; Glucosamine Sulfate

Glucose (monosaccharide)
Type of sugar that circulates in the bloodstream, thus the term "blood glucose levels" or "blood sugar." All carbohydrates, whether simple or complex, are eventually converted to glucose in the body. Glycogen is many units of glucose together.

Glucose Tolerance Factor (GTF)
GTF is thought to be a complex of chromium, nicotinic acid, and the amino acids glycine, cystein and glutamic acid (these aminos are components of gluthathione). GTF is thought to be synthesized by the liver. In many people, chromium is likely the deficient substrate for GTF formation. GTF is found in foods such as organ meats, whole gains, cheese, mushrooms and brewer's yeast. See: Chromium GTF

Glutamine
An amino acid. Glutamine is the most abundant amino acid in muscle tissue. Studies are beginning to show that having extra glutamine in your body may be important to maximize muscle growth, by increasing growth hormone levels. Glutamine also is important to maintain proper health, and is shown to have anabolic and anticatabolic properties.
See: L-Glutamine

Glutathione
A tripeptide of glutamine acid, cysteine, and glycine; fundamentally important in cellular respiration. See: Reduced L-Glutathione

Glycemic Index
Applies to the amount of sugar in one's blood. The normal range is 70-110mg/100ml.

Glycine
Of special value as a source of creatine which is essential for muscle function, braking down glycogen and freeing energy. Produces glycogen which mobilizes glycogen (a stored energy source of glucose) from the liver. Builds up the immune system, producing immunoglobulins and antibodies. Acts as a nitrogen pool for the syntheses of nonessential amino acids. Effective for hyperacidity, used in many gastric antacid agents.

Glycogen
It is a term for many units of glucose strung together. The body stores glycogen in two areas, the liver and the muscles. Only about 5 grams, or 20 calories worth of glucose flows in the blood. Liver stores about 75 to 100 grams, or 300 to 400 calories; an hour of aerobics can burn up half the liver glycogen content. The muscles store around 360 grams, or 1,440 calories.

Glycogen (liver)
Liver glycogen is a fuel reserve that helps maintain blood glucose levels. This is important because the brain relies on a constant supply of glucose to function properly.

Glycogen (muscle)
Muscle glycogen is extremely important for bodybuilding, since it's the primary fuel that powers anaerobic training, such as lifting weights.

Goldenseal root
A stimulant that increases your bodies tonic properties. Stimulates secretion of bile.

Gotu kola
Gotu kola (Centella asiatica (L.) Urban), of the Apiaceae family, is also known as centella and pennywort. Native to areas such as Sri Lanka and South Africa, the leaves of this swamp plant have been used around the world for centuries to treat leprosy, cancer, skin disorders, arthritis, hemorrhoids, and tuberculosis.

Grape seed extract
Source of proanthocyanadins, an important antioxidant See: Grape Seed
