GLUCOSAMINE SULFATEThis product is a dietary supplement for people who have been diagnosed with or are concerned about osteoarthritis which is the most common form of arthiritis and is usually a result of wear and tear or prior trauma. In osteoarthritis the cartilage begins to wear away. Common joints affected are the spine, hands, hips, and knees. Your body continually tries to grow more cartilage as it is the wear surface between your joints. It is the cartilage cells that make cartilage. In osteoarthritis the wear and tear process has exceeded the repair process and the joint slowly wears out. By taking Glucosamine Sulfate you are providing your body with an ingredient which may help it to grow more cartilage. This is a nutritional supplement, not a drug, and you should give it a three month trial taking one capsule twice a day. If it is working you may feel decreased joint stiffness and ache especially in the morning. If you feel nothing after three months you may consider discontinuing use of this product. Do not take this product if you are allergic to shellfish. This product contains no yeast, wheat gluten, soy protein, milk/dairy, corn, sodium, sugar, starch, artificial coloring, preservatives, or flavoring.
