Naturally Supportive glucosamine and chondroitin supplements
Glucosamine and chondroitin are known as chondroprotective agents. Chondroprtective agents are natural compounds the body produces to promote healthy joint function. Chondroprotective agents work by supporting joint fluid levels to promote lubrication. In addition, glucosamine and chondroitin combat harmful free radical enzymes that may damage joint cartilage, as well as help enhance circulation in blood vessels that lead to the joint. Glucosamine and chondroitin supplements work in effective ways.

Glucosamine is a key building block of cartilage that is derived from the sugar glucose, the main sugar found circulating in the blood stream. Glucosamine is concentrated in joint cartilage and stimulates chondrocytes (cartilage cells) to help maintain cartilage and collagen. It enters the joint space and is incorporated into proteoglycans. These are cells that form large structures and attract water to the joint space for lubrication of cartilage during movement.

Chondroitin sulfate is a natural component of human cartilage composed of a long chain of specialized polysaccharides (sugars). Chondrointin sulfate supports the structural components of joint cartilage and promotes hydration of the joint for improved mobility. Since cartilage does not have blood vessels to supply itself with nutrients, chondroitin supports the joint by channeling nutrients to cartilage cells.

Glucosamine and Chondroitin have proven to be safe when taken at recommended dosages. Some mild gastro-intestinal side effects such as heart burn or nausea may occur with the consumption of glucosamine and chondroitin.

Children, women who are pregnant, and women who could become pregnant should not take this product as safety studies have not established their effects on a child or developing fetus over time. Glucosamine is an amino sugar and people with diabetes should check their blood sugar levels more frequently when taking this supplement. If you are taking chondroitin sulfate in addition to a blood thinning medication or daily aspirin therapy, have your blood clotting time checked more often.

This supplement is similar in structure to the blood thinning drug heparin, and the combination may cause bleeding in some individuals. If you are allergic to shellfish, consult your doctor before deciding to take glucosamine. In most cases however, allergies are caused by proteins in shellfish, not chitin, a carbohydrate from which glucosamine is extracted.

Frequently Asked Questions

What is glucosamine?

Glucosamine is a type of sugar produced in the body that is an important building block of joint cartilage. Cartilage is the main tissue that cushions and protects joints during movement. Glucosamine provides the raw materials needed to strengthen cartilage and attract water into the joint space for lubrication and smoothness.

Who should take glucosamine?

Glucosamine is appropriate for anyone with uncomfortable, stiff and aching joints. It can also benefit those who participate in regular rigorous physical activity by helping to maintain joint health and reduce stress from repetitive or jarring motions.

How does glucosamine work?

When delivered into the joint, glucosamine binds to cartilage to help build a compound called glycosaminoglycan, the main structural component of cartilage. Other evidence shows glucosamine may help cartilage cells called chondrocytes, to produce new cartilage and renew joint function.

Where does glucosamine come from?

The shells of crabs, shrimp and oysters contain good sources of glucosamine. To produce a supplement, the crab shell is synthesized in a laboratory to produce glucosamine for supplements.

I’ve noticed several different forms of glucosamine. What are the differences between them?

The difference between various forms of glucosamine is simply the source they come from, and how they are stabilized. Different types include glucosamine sulfate, glucosamine hydrochloride (HCl) and N-acetyl-glucosamine (NAG). For example, glucosamine sulfate is stabilized with one of two mineral salts, sodium chloride (NaCl) or potassium chloride (KCl).Many experts consider glucosamine sulfate to be the best source because it is believed to be more easily absorbable in the human body. Glucosamine sulfate also has hundreds of research studies showing its benefits. Other varieties have yet to demonstrate the same level of effectiveness in clinical trials.

How long will it take for me to feel positive results?

The benefits of glucosamine supplementation develop over time. Generally, it may take 2 to 8 weeks before you see noticeable results.

Are there any side effects or drug interactions with glucosamine?

There are no significant side effects when taking glucosamine. There have been reports of minor upset stomach and heartburn in some individuals. People who are highly allergic to seafood should use caution before taking glucosamine. There are no known drug interactions.

Can I take glucosamine if I have diabetes?

In general, yes. Research suggests that taking glucosamine will not trigger or aggravate insulin resistance or high blood sugar. However, people with diabetes should take prudent caution and consult a physician before taking glucosamine.

What is an effective dosage of glucosamine?

People with joint discomfort should take 1,500 mg of glucosamine a day (500mg three times per day), or as recommended by a healthcare professional.

Should I take glucosamine with a meal?

Yes. For maximum effectiveness, glucosamine should be taken with a meal.
