A, Vitamin (Retinol)

Vitamin A is one of four fat-soluble vitamins necessary for good health. It serves an important role as an antioxidant by helping to prevent free radicals from causing cellular damage. Adequate levels are important for good eyesight, and poor night vision may be one of the first symptoms of a deficiency. It is also necessary for proper function of the immune, skeletal, respiratory, reproductive, and integumentary (skin) systems.

Acesulfame-K

An artificial sweetener. Approved in 1988, this sweetener is 200 times sweeter than sugar, yet has a bitter taste. The 'K' in its name stands or potassium. Acesulfame-K is not metabolized by the body. You can cook and bake with it. There are no reported side effects with this sweetener although it may increase insulin secretion, which can cause concern for diabetics.

Acetyl-L-Carnitine (ALC)

The acetyl ester of carnitine, ALC acts as an antioxidant, has protective effects in the brain, and stimulates hormone (including testosterone) release.

Alanine

An amino acid. BCAAs are used as a source of energy for muscle cells. During prolonged exercise, BCAAs are released from skeletal muscles and their carbon backbones are used as fuel, while their nitrogen portion is used to form another amino acid, Alanine. Alanine is then converted to Glucose by the liver. This form of energy production is called the Alanine-Glucose cycle, and it plays a major role in maintaining the body's blood sugar balance.

Alpha Lipoic Acid (ALA)

A sulfur bearing phytonutrient with antioxidant properties; amplifies effects of other antioxidants. It is an insulin potentiator that may be, in some respects, the very best insulin mimicker. An analogy of what ALA does is that if ALA was an individual, he would be the one which yells at the muscle cells to pick up the key, open the door, and help bring in the creatine.

ALA is a sulfur bearing compound with antioxidant properties. It plays a role in energy metabolism. ALA amplifies the ability of other antioxidants to combat free radicals and enhance recovery. Also may enhance insulin sensitivity, improving the body's ability to add lean mass and reduce fat.

Amino Acids

Nitrogen-bearing organic acids that are the building blocks of protein. The branched chain amino acids are Leucine, Valine and Isoleucine.

Anabolic

Metabolic condition in which new molecules are synthesized (growth).

Androstenedione

An androgen (male hormone). Androgens are produced in two sites in the male body - most originate in the testes, but some potent male hormones are produced by the adrenal glands, located just above the kidneys. Androstenedione is a pivotal adrenal steroid that's actually one step closer to being converted to testosterone than DHEA. It raises your testosterone levels and can provide more strength.

Androstenedione really does raise testosterone above normal levels and could be hazardous. Side effects include acne, male baldness, and a decrease in 'good' cholesterol, which may lead to heart disease. This supplement might be reclassified as a steroid by the FDA, and it is banned in the NFL, Olympics, and other major sports organizations.

Antioxidants

Any substances that prevent or impede cell oxidation (destruction) by free radicals, etc.

Arginine

A conditionally essential amino acid with anabolic and immune system supportive effects. It is required for growth, immune function, wound healing and many aspects of protein metabolism. Arginine is necessary for the production of growth hormone. It is also a precursor for nitric oxide, a critical substance that helps regulate the function of cardiovascular, nervous and immune systems and which is essential for muscle growth.

Ascorbic Acid

Also known as Vitamin C. A water soluble vitamin, and an antioxidant. Your body cannot store Vitamin C, so you must supplement it regularly. It is not resistant to heat, so cooking will destroy it. Vitamin C functions primarily in the formation of collagen, the chief protein substance of your body's framework. It also helps in the production of vital body chemicals. Vitamin C also is a detoxifier (helping cleanse your body of toxins).

Aspartame

An artificial sweetener. Known by the trade name NutraSweet, it is an artificial sweetener. Certain people should avoid products that contain Aspartame. They are people who cannot metabolize the amino acid Phenylalanine, which is an ingredient in aspartame; and people who are suspectable to headaches. It is nearly 200 times sweeter than sugar. Aspartame is produced from the amino acids L-asartic acid and L=phenylalannine. It has been approved for use in certain goods since 1981. Heat causes aspartame to lose its sweetness, therefore, you can't bake with it. Unlike some sweetners, it has no aftertaste.

Aspirin

Can reduce soreness after a hard workout, or lower your risk of heart disease. Can also reduce your risk for throat or stomach cancer.

ATP (Adenosine Triphosphate)

The body's energy currency, released when fuel molecules are broken down.
