A Scientific Overview of… Chondroitin Sulfate
Powerful Natural Support for Joints and Bones
Found Throughout Nature
Chondroitin sulfate (CS) is one of six related substances called glycosaminoglycans (GAGs), which are also referred to as mucopolysaccharides. GAGs occur widely throughout the animal kingdom — in vertebrates and invertebrates, terrestrial and marine organisms, and mammals and non-mammals. Six kinds of GAGs have been found in the tissues and fluids of vertebrates: chondroitin sulfates, keratin sulfates, dermatin sulfates, hyaluronic acid, heparin, and heparin sulfate.

Found in Connective Tissue
CS is widely found in the connective tissues of animals. It occurs in three slightly different forms: CSA, CSB, and CSC. CSA and CSC are found in nasal and tracheal cartilage, articular cartilage (joints), bones, sclera, leukocytes and blood platelets, skin, and umbilical cords. CSB has been found in skin, umbilical cords, and cardiac valves.

Vital for Joint Function
Adequate amounts of CS are vital for normal joint function and maintenance as well as many other self-healing mechanisms. The following list of activities have been proven in numerous scientific studies.
1. Osteogenesis: CSA is an important participant in bone calcification and CSC in bone integrity maintenance (Paroli, 1991; Maurau, 1988).*

2. Analgesic and restorative effect: A very important property of CS is its ability to stimulate the chondrocite (cell that synthesizes the proteoglycans in the articular cartilage), which is conducive to the proper maintenance of the cartilage matrix (Serni, 1991; Vacha, 1994).*

3. Enzymatic inhibition: The capacity of CS to inhibit the action of destructive enzymes of the articular cartilage protects joints and helps maintain harmonic balance of healthy enzyme activity. This in turn helps avoid degradation of hyaluronic acid, a necessary molecule for the maintenance of hydration and viscosity of synovial fluid (Avila, 1976; Marossy, 1981; Pipitone, 1991; Videla Dorna et al., 1994).*

4. Anti-inflammatory effect: (Paroli, 1991; Pipitone, 1991; Rashmir-Raven, 1992).*

Mr. Dickens, still spry for 22.

22 Year Old Cat Still Happy to Jump on Window Bench for Breakfast

Dear Springtime,

Mr. Dickens adopted us 22 years ago. He wears a tortoiseshell coat, and has outlived both his original master and his adopted master who lived to age 80. The vet's records say he was about a year old when he first saw him. He has an annual checkup, teeth get cleaned every few years – no cavities, no extractions ever. …and while he is a bit slow he has no problem jumping up on the window bench for his breakfast and dinner – breakfast is laced with J-Flex Concentrate. At the rate he is going, he may well outlast me… I became acquainted with J-Flex Concentrate from a friend who has horses. Thanks for carrying this product.
