The drug Tacrine appears to slow the progression of Alzheimer's disease, but there is currently no way to stop the disease.
Amino acids – The building blocks from which proteins are made. Dietary amino acids are classified as essential or non-essential. Essential amino acids (histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine) cannot be manufactured by the body and must be supplied in the diet or ill-health results. The non-essential amino acids are also essential for health, but can be synthesized in the body from the essential amino acids. Arginine, ornithine, cysteine, cystine, taurine and tyrosine are classified as non-essential amino acids but may be essential for individuals with certain diseases or nutritional concerns. A suboptimal intake of the essential amino acids increases the body's need for the non-essential amino acids.
Amino Acids A group of nitrogen containing, carbon-based organic compounds that serve as the building blocks from which protein and muscle are made. All of the amino acids are important in the production of new protein or in some other metabolic process, but from a nutritional standpoint some are considered "essential" and others "non-essential." Amino acids function as the building blocks of proteins. Chemically, amino acids are organic compounds containing an amino (NH2) group and a carboxyl (COOH) group. Amino acids are classified as essential, nonessential and conditionally essential. If body synthesis is inadequate to meet metabolic need, an amino acid is classified as essential and must be supplied as part of the diet. Essential amino acids include leucine, isoleucine, valine, tryptophan, phenylalanine, methionine, threonine, lysine, histidine and possibly arginine. Nonessential amino acids can be synthesized by the body in adequate amounts, and include alanine, aspartic acid, asparagine, glutamic acid, glutamine, glycine, proline and serine. Conditionally essential amino acids become essential under certain clinical conditions.
Amino Acids, Essential There are nine amino acids that the body either cannot produce at all or cannot make in sufficient quantity to meet its needs. They are: histidine, isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine.
Amino Acids, Non-essential These amino acids are considered nonessential due to the fact that they can be made in the body from the essential amino acids. They are: alanine, arginine, asparagine, aspartic acid, cysteine, glutamine, glutamic acid, glycine, hydroxyproline, proline, serine and tyrosine.
Anabolism The building up of the body's substance; the constructive phase of metabolism.

It is the most severe allergic reaction to an allergen and requires immediate medical attention when it occurs.
Androgen – This term refers to the male sex hormones (testosterone, androsterone) or any agent that encourages the development of male sex characteristics.
Androstenedione – A weak androgenic steroid secreted by the adrenal cortex, testes, and ovary. In normal males less than 5% of their testosterone comes from the conversion of adrenal androstenedione. Androstenedione is converted to testosterone by the enzyme 17-ketoreductase. Androstenedione and testosterone are converted to estrone and estradiol in peripheral tissues (primarily in adipose tissue but also in muscle, kidney, liver and the hypothalamus) by aromatase. The conversion of androstenedione and testosterone accounts for more than 75% of the estrogens in the plasma of normal men. The rest is synthesized in the testes. Gonadotropin secretion may be partially controlled by estrogen formation in the hypothalamus.
anemia Anemia is a condition in which a deficiency in the size or number of erythrocytes (red blood cells) or the amount of hemoglobin they contain limits the exchange of oxygen and carbon dioxide between the blood and the tissue cells. Most anemias are caused by a lack of nutrients required for normal erythrocyte synthesis, principally iron, vitamin B-12, and folic acid. Others result from a variety of conditions, such as hemorrhage, genetic abnormalities, chronic disease states or drug toxicity.

antigen A foreign substance (almost always a protein) that, when introduced into the body, stimulates an immune response.
antioxidant Antioxidants protect key cell components by neutralizing the damaging effects of "free radicals," natural byproducts of cell metabolism. Free radicals form when oxygen is metabolized, or burned by the body. They travel through cells, disrupting the structure of other molecules, causing cellular damage. Such cell damage is believed to contribute to aging and various health problems.
Antioxidants – Nutrients that combat ever-present free radicals created through oxidation in the body. Free radicals are believed to contribute to a number of health problems. Antioxidants are nutrients that play a vital role in cellular health. Cells are vulnerable to a process called oxidation. Antioxidants are fighter nutrients in the oxidative process that find and "quench" free radicals before they can begin their damaging reaction. Antioxidant nutrients include vitamins C and E, beta-Carotene, the mineral selenium, proanthocyanidin (or OPC's from grape seed extract) and pycnogenol.
antisense A piece of DNA that produces the mirror image, or antisense messenger RNA, that is exactly opposite in sequence to one that directs the cells to produce a specific protein. Since the antisense RNA binds tightly to its image, it prevents the protein from being made.

biotechnology The simplest definition of biotechnology is "applied biology." The application of biological knowledge and techniques to develop products. It may be further defined as the use of living organisms to make a product or run a process. By this definition, the classic techniques used for plant and animal breeding, fermentation and enzyme purification would be considered biotechnology. Some people use the term only to refer to newer tools of genetic science. In this context, biotechnology may be defined as the use of biotechnical methods to modify the genetic materials of living cells so they will produce new substances or perform new functions. Examples include recombinant DNA technology, in which a copy of a piece of DNA containing one or a few genes is transferred between organisms or "recombined" within an organism.
Biotin One of the B-vitamins that functions as a co-enzyme in the metabolism of carbohydrates and fats. The biotin co-enzyme also serves in crucial roles in the breakdown of amino acids. Deficiency of the vitamin can result in hair loss and dermatitis, thus it is found as a popular ingredient in hair care products. Essential for metabolism of proteins and carbohydrates.

Caffeine does not accumulate in the body over the course of time and is normally excreted within several hours of consumption.
Calcium – A mineral that helps build and maintain strong bones and teeth, regulate heartbeat and muscle contractions, and ensure proper blood clotting. Adequate intake can help prevent or minimize osteoporosis. The most abundant mineral in the body and its primary function is to build strong bones and teeth and to maintain a balanced level in the blood. Blood calcium levels are essential to life. When we don't consume enough calcium in our diet to maintain sufficient levels, the mineral is drawn from our bones. So even though most of the calcium is housed in our bones, the blood and cellular concentrations of this mineral are maintained first. This combined with the fact that calcium absorption becomes less efficient with age is a major contributor to osteoporosis. According the National Institutes of Health Consensus Development Panel on Optimal Calcium Intake, the recommended daily allowance of calcium is 1200-1500 mg. A mineral that builds bones and strengthens bones, helps in muscle contraction and heartbeat, assists with nerve functions and blood clotting. Teens 18 years and younger should strive to consume about 1,300 milligrams per day. Individuals 50 years and older need about 1,200 milligrams per day. Everyone else should strive for about 1,000 milligrams per day. Milk and other diary foods such as yogurt and most cheeses are the best sources of calcium. In addition, dark green leafy vegetables, fish with edible bones, and calcium fortified foods supply significant amounts.
Calcium Citrate Malate (CCM) A patented form of calcium sold exclusively at GNC. Studies in post-menopausal women over the age of 55 demonstrate CCM results in 70% less bone loss when compared to a diet without calcium supplementation, and it can also result in 40% less bone loss when compared to ordinary calcium supplementation.
calorie A calorie is the amount of energy required to raise the temperature of one milliliter (ml) of water at a standard initial temperature by one degree centigrade (1°C).
Calories – Measurement of the potential of food to supply energy. Carbohydrates – The body’s principal source of energy. Simple carbohydrates come from sugars; complex carbohydrates come from starches and fiber. The body converts them to glucose, which is used to energize cells.
carbohydrateCarbohydrates are organic compounds that consist of carbon, hydrogen and oxygen. They vary from simple sugars containing from three to seven carbon atoms to very complex polymers. Only the hexoses (sugars with six carbon atoms) and pentoses (sugars with five carbon atoms) and their polymers play important roles in nutrition. Carbohydrates in food provide 4 calories per gram. Plants manufacture and store carbohydrates as their chief source of energy. The glucose synthesized in the leaves of plants is used as the basis for more complex forms of carbohydrates. Classification of carbohydrates relates to their structural core of simple sugars, saccharides. Principal monosaccharides that occur in food are glucose and fructose. Three common disaccharides are sucrose, maltose and lactose. Polysaccharides of interest in nutrition include starch, dextrin, glycogen and cellulose. The sugars and starches in food. Sugars are called simple carbohydrates and found in such foods as fruit and table sugar. Complex carbohydrates are composed of large numbers of sugar molecules joined together and are found in grains, legume and vegetables such as potatoes, squash and corn.
carcinogens, natural and synthetic The basic mechanism involved in the entire process of carcinogenisis—from exposure to the organism to expression of tumors—are qualitatively similar, if not identical, for the synthetic and naturally occurring carcinogens. Consequently, both naturally occurring and synthetic chemicals can be evaluated by the same epidemiologic or experimental methods and procedures.
Carnitine – An amino acid essential for the breakdown of fat into energy. Carnitine may improve the utilization of fats for energy and can be beneficial in conditions associated with impaired fat breakdown and energy production. Carnitine may be beneficial in heart disease, enhancing physical performance, Alzhiemers disease, diabetes, liver disease, and protection against drug toxicity. This compound plays a central role in lipid metabolism. L-Carntine transports long chain fatty acids into the "mitochondria," the cell's energy factories. Carnitine is stored in skeletal muscle. Carnitine regulates the function of enzymes involved in energy production. Carnitine is a non essential amino acid.

Please note that chitosan may cause an allergic reaction in persons allergic to shellfish.
Cholesterol – Substance manufactured by the liver and other organs and consumed via animal fat. High-fat diets increase the amount made. It is believed that high levels lead to collection of cholesterol in the arteries, possibly leading to serious health risks. A waxy, fat-like substance manufactured in the liver and found in all tissues. In foods, only animal products contain cholesterol. An elevated blood level of cholesterol constitutes an increased risk of developing coronary heart disease.
cholesterol (dietary) Cholesterol is not a fat, but rather a fat-like substance classified as a lipid. Cholesterol is vital to life and is found in all cell membranes. It is necessary for the production of bile acids and steroid hormones. Dietary cholesterol is found only in animal foods. Abundant in organ meats and egg yolks, cholesterol is also contained in meats and poultry. Vegetable oils and shortenings are cholesterol-free.
cholesterol (different types) Blood cholesterol is divided into three separate classes of lipoproteins: very-low density lipoprotein (VLDL); low-density lipoprotein (LDL), which contains most of the cholesterol found in the blood; and high-density lipoprotein (HDL).
LDL seems to be the culprit in coronary heart disease and is popularly known as the "bad cholesterol." By contrast, HDL is increasingly considered desirable and known as the "good cholesterol."
cholesterol (serum, or blood) High blood cholesterol is a risk factor in the development of coronary heart disease. Most of the cholesterol that is found in the blood is manufactured by the body, in the liver, at a rate of about 800 to 1,500 milligrams a day. By comparison, the average American consumes 300 to 450 milligrams daily in foods.
Choline – A nutrient that helps prevent the accumulation of fat in the liver; aids in the detoxification of metabolic wastes and toxins. A component of phosphatidylcholine, a component of lecithin, found in soy and other foods. It is important for cell membrane function and signaling between nerve cells. It is necessary for fat and cholesterol metabolism.
Chondroitin sulfate The most abundant mucopolysaccharide in the body. It is synthesized in significant amounts but the concentration declines with the normal aging process. It acts as the flexible connecting matrix between tough protein filaments in cartilage to form a polymeric system similar to reinforced rubber. It makes up many body tissues including cartilage, tendons, ligaments, skin, mucus and structures in the eyes. Along with regular exercise, chondroitin sulfate and certain other dietary ingredients may be helpful in maintaining joint health.
Chromium – Mineral important in the metabolism of carbohydrates and fats; helps build lean muscle tissue and regulate blood sugar levels. An essential mineral that is found in many unrefined foods including Brewer's yeast, calf liver, wheat germ, nuts and cheese. Chromium is involved in carbohydrate metabolism and may help regulate blood glucose availability.
Chromium Picolinate Supplementation, along with proper diet and exercise, may help reduce body fat and increase lean body mass in some moderately obese people. It is essential for carbohydrate (sugar), fat protein metabolism. Chromium is an essential element that helps insulin work more effectively and improves glucose tolerance in some individuals.
chromosome Thread-like components in the cell that contain DNA. They make proteins. Genes are carried on the chromosomes.
Citric acid A naturally occurring acid in citrus type fruits and berries. Stabilizes the pH value of the skin. Citric acid exhibits astringent and antioxidant properties.
CLA – (Conjugated linoleic acid) is a naturally occurring nutrient which scientists have discovered exerts a positive effect on protein and fat metabolism. CLA is a fatty acid that is present in dairy products, beef, poultry, and eggs. At this time, research on CLA focuses on its role in cellular health and metabolism.
clairaudience: 1. The supposed power to perceive sounds (e.g., music and voices) not within the known extent of human perception. 2. The supposed power to perceive sounds from "alien dimensions," such as the voices of spirits.
clairvoyant: One who claims or appears to have clairvoyance, the alleged ability to obtain information in a way that does not involve using any of the known human senses.
clinical trials Clinical trials undertake experimental study of human subjects. Trials may attempt to determine whether the finds of basic research are applicable to humans, or to confirm the results of epidemiological research. Studies may be small, with a limited number of participants, or they may be large intervention trials that seek to discover the outcome of treatments on entire populations. The "gold standard" clinical trials are double-blind, placebo-controlled studies which employ random assignment of subjects to experimental and control groups unknown to the subject or the researcher.
Cod Liver Oil A natural source of Vitamins A and D and Omega-3 fatty acids. Omega-3 fatty acids help maintain healthy cardiovascular function by promoting normal triglyceride levels and vascular tone. Omega-3 fatty acids help reduce stickiness of red blood cells, thereby promoting healthy circulation. Cod Liver Oil is a traditional way of receiving Vitamin A and Vitamin D. GNC's Cod Liver Oil is microfiltered to remove unwanted pollutants and manufactured at low temperatures without solvents or chemicals. Cod Liver Oil is an Omega-3 Fatty Acid that supplies EPA and DHA.
Coenzyme An enzyme activator often composed of non-protein substances; like vitamins.
Coenzyme Q 10 – Vital to energy production at the cellular level; used for endurance improvement. Supplementation may decrease fatigue, muscle weakness and obesity. Also recognized for its strong antioxidant properties.
collagen hydrolysate A functional component of gelatin which may help improve some symptoms associated with osteoarthritis.
collective unconscious (universal consciousness): Alleged inborn psychological bedrock--common to all humans but varying with the particular society, people, or race--that enables telepathy.
Colloid A substance (as gelatin, albumin, or starch) dispersed through another medium. Colloidal means that one substance is suspended in another.
Concentrated herb Confirmed as the true herbal species. Concentrated to produce a more potent extract. This proprietary process removes the pulp and fiber that does not add value to the herb. Most concentrated herbs are offered in advanced softgel delivery system that supplies a beneficial concentration and is easier to swallow than conventional tablets. A more potent product than the herbal Plus fingerprinted. Each capsule supplies 1,000 mg. of the herbal species.
confounding variable or confounding factor A "hidden" variable that may cause an association which the researcher attributes to other variables.
conjugated lenoleic acid (CLA) A type of fatty acid found in cheeses and some meat products which may provide the health benefits of improving body composition and decreasing the risk of certain cancers.
Continuing Survey of Food Intake of Individuals (CSFII) A part of the National Nutrition Monitoring System which was the first nationwide dietary intake survey designed to be conducted annually. The survey is conducted by the USDA.
control group The group of subjects in a study to whom a comparison is made in order to determine whether an observation or treatment has an effect. In an experimental study it is the group that does not receive a treatment. Subjects are as similar as possible to those in the test or treatment group.
controlled experiment In this type of research, study subjects (whether animal or human) are selected according to relevant characteristics, and then randomly assigned to either an experimental group, or a control group. Random assignment ensures that factors known as variables, which may affect the outcome of the study, are distributed equally among the groups and therefore could not lead to differences in the effect of the treatment under study. The experimental group is then given a treatment (sometimes called an intervention), and the results are compared to the control group, which does not receive treatment. A placebo, or false treatment, may be administered to the control group. With all other variables controlled, differences between the experimental and control groups may be attributed to the treatment under study.
Copper – Mineral important in the formation of red blood cells; keeps bones, blood vessels, nerves and the immune system healthy. The body contains about 100mg of this trace mineral, which is stored in the liver. It serves as a constituent of enzymes, which function in a number of capacities, such as in the oxidation of ferrous iron to ferric iron, manufacturing of collagen and the healing of wounds. Copper is also involved in respiration and the release of energy.
Coronary Heart Disease (CHD) Also called Coronary Artery Disease (CAD). CHD is a condition that results when the coronary arteries are narrowed by atherosclerotic deposits of fibrous and fatty tissue. Coronary artery disease is the most common underlying cause of cardiovascular disability and death. Men are affected about four times as frequently as women. Risk factors include hypertension, high cholesterol, smoking, diabetes and adverse reactions to mental stress. After menopause women are also at risk.
correlation An association, or when one phenomenon is found to be accompanied by another. A correlation does not prove cause and effect. Correlation may also be defined statistically.
Cranberry The American Cranberry, also known as the trailing swap cranberry, is typically used as aid in maintaining healthy urinary tract. It inhibits the adhesion of E. coli bacteria to the wall of the ureter, preventing infection.
Creatine A substance made up of three amino acids: methionine, arginine and glycine. A small amount is produced in the liver and stored in your muscles. It is used to make creatine phosphate, a substance that helps support the ATP refueling process, which provides energy. This high-energy phosphate is great for bodybuilders and serious athletes because it provides support for energy production.
Creatine monohydrate – Maximizes the body’s level of stored creatine phosphate; results in increased peak athletic performance and shortened muscle recovery time.
crop residues Plant materials remaining from the former crop that are left on the soil surface after planting form crop residues. Crop residues reduce soil erosion, air and surface water pollution, conserve soil moisture, and improve the soil by adding organic matter.
crustacean Any of the various aquatic arthropods, including lobsters, crabs, shrimps and barnacles. Characteristically have segmented bodies, chitinous exoskeletons and paired, jointed limbs.
cultural controls An integrated pest management method which includes annual crop rotation to discourage pests and weed production.
cyclamate A sweetener which is 30 times sweeter than sucrose, calorie free and heat stable and works synergistically with other sweeteners. It is approved for tabletop use in Canada and more than 50 countries in Europe, Asia, South America and Africa. Since 1970, however, the use of cyclamate has been banned in the United States on the basis of a study that suggested that cyclamates may be related to the development of bladder tumors in rats. Although 75 subsequent studies have failed to show that cyclamate is carcinogenic, the sweetener has yet to be reapproved for use in the United States.
Cysteine Is a principal source of sulfur on the diet which is found in skin and nails. Cysteine is a main source of sulfhydryl groups in many proteins in cells. It plays an important role in glutathione structure that acts as a reductant and is scavenger of free radicals. It is also a part of glutathione peroxides, the enzyme that protects against lipid peroxides in the body.
