Chondroitin sulfate

Chondroitin is best known to the general public as a remedy for osteoarthritis, which is a form of arthritis caused by wearing away or degeneration of the cartilage that cushions the ends of bones. It is thought that the drying out of cartilage tissue in osteoarthritis is a major cause of tissue destruction. Chondroitin sulfate is given together with glucosamine, a compound that is a building block of cartilage. The chondroitin helps to attract and hold fluid within cartilage tissue. Tissue fluid keeps cartilage healthy in two ways: it acts as a shock absorber within the joints of the body, thus protecting cartilage from being worn away by the bones; and it carries nutrients to the cartilage.

Description

Cartilage is a type of dense connective tissue found in humans and other animals. Bluish-white or gray in color, the semi-opaque tissue has no nerve or blood supply of its own. Cartilage supplements come from such animal sources as cattle, sheep, sharks, and chickens, with cows and sharks being the predominant sources.

Bovine cartilage supplements are derived from the windpipes of cows, while the cartilage from the heads and fins of sharks is used for shark supplements.

Description

Barley grass is the leaf portion of the barley plant (Hordeum vulgare) that remains after the seeds havebeen removed. As a grass, it is also known as a distichon, meaning that it grows in two separate ranks, or rows. The rows of barley grass are parallel to the central axis, forming a loose sheath over the stem, which is sometimes called the culm. This stem is hollow and jointed, and the seeds are ellipitical and furrowed. The barley plant, an annual that requires reseeding each year, reaches a height of up to 3 ft (about 1 m). The plant has an extensive history in human and animal nutrition. As a nutritional supplement, it is preferable to use young barley plants that have not yet developed seeds.

Description

Caffeine is a drug that stimulates the central nervous system (CNS). Caffeine is found naturally in coffee, Kola seed kernels or nuts (Cola nidtida), and a variety of teas. Other foods and beverages, such as chocolate and soft drinks, also contain caffeine, and the drug can be purchased in over-the-counter tablet and capsule form (No Doz, Overtime, Pep-Back, Quick-Pep, Caffedrine, and Vivarin). Some prescription pain relievers, medicines for migraine headaches, and antihistamines also contain caffeine.

Precautions

When adding calcium supplements to the diet, it is recommended that it not be taken within one to two hours of eating bran, or whole grain cereals or breads. Large amounts of alcohol or caffeine containing beverages or tobacco should be avoided. Large amounts of calcium, phosphates, magnesium, or vitamin D in medication or dietary supplements should not be taken unless directed by a physician. Those with diarrhea, stomach trouble, parathyroid disease, sarcoidosis, or kidney stones should consult with their physician before taking calcium.
