Chondroitin Products for Arthritis

Chondroitin is an amino sugar, which is produced within cartilage cells. It is one of the basic substances of articular cartilage, the type of cartilage found within joints. For this reason, there is great interest in chondroitin sulfate as a dietary supplement for patients with osteoarthritis. It stabilises the cartilage and helps to counteract the external pressure on the articular cartilage.

Because it is formed by the human body itself, chondroitin is considered to be well tolerated and free from side effects. The results of several clinical studies have shown a positive effect on the symptoms of arthritis and other rheumatic complaints.

Chondroitin sulfate is available on the market in tablet form and is to be preferred over chondroitin hydrochloride.

Summary: Chondroitin and osteoarthritis

Chondroitin is a substance that occurs naturally in joints. Studies have shown the anti-inflammatory and cartilage-building effect of glucosamine. Like most food supplements, which act on the physiological level, chondroitin takes from two to six months to have a noticeable effect.

It’s effectiveness can be significantly enhanced by combining it with glucosamine and Omega-3. Side effects are not anticipated with either chondroitin, glucosamine or omega-3 fatty acids. Chondroitin thus belongs to a group of natural treatments for osteoarthritis and arthritis.

Chondroitin for Osteoarthritis

A number of studies suggest that chondroitin sulfate appears to have an analgesic, anti-inflammatory and presumed cartilage-building effect in humans.

In clinical studies, the daily dosage is usually between 300 mg and 1,200 mg. The studies often include glucosamine, which has recently become more popular as a treatment along with omega-3 fatty acids derived from fish oil.

Chondroitin’s key benefits are that frequently a large number of patients report a decrease of pain and that it reduces the inflammatory swelling of joints.

The amino sugar has been shown to slow joint destruction1 in clinical studies. It works in the cartilage mainly by reducing inflammation, and reducing the formation of pro-inflammatory and cartilage-destroying substances such as nitrogen monoxide2. With a lesser degree of inflammation in the joint fewer cartilage cells die off. This is a primary factor in the long-term preservation of the joint.

Combining Chondroitin with other micro nutrients!

Improve the Effect of Chondoritin Sulfate by Combining it with Other Nutrients.

Chondroitin sulfate in humans has an intrinsic effect, which has been confirmed in numerous clinical studies3 4 5. However, the combination with other agents appears to enhance the effect even further. For osteoarthritis patients, the combined administration of chondroitin and glucosamine has proven effective6 7 8.

Chondroitin sulfate molecular structureResearchers studied samples of cartilage taken from cows. They showed that chondroitin and glucosamine decreased the formation of various inflammatory factors and enzymes. Thus, the articular cartilage in the cell culture was less severely damaged9.

Another study evaluated the combination of chondroitin sulfate and healing earth containing sulphate on the development of osteoarthritis. It was found that the healing earth alone had no effect against arthritic joint changes in mice. In contrast, the combination of the two improved visible osteoarthritis symptoms10. The cartilage damage was somewhat mitigated, and inflammation was less frequent. With this experiment, the researchers again showed anti-inflammatory activity. When the inflammation is suppressed, there are fewer free radicals and other harmful substances in the joint, protecting the cartilage from gradual, long-term disintegration.

In addition, omega-3 fatty acids combine very well with chondroitin and glucosamine11. Clinical studies have shown promising effects when all three nutrients were combined12 .

Chondroitin treatment should be long term

Cartilage Recovers Slowly. Chondroitin Effect Therefore Only Long-term

Cartilage regenerates about ten times slower than skin or other perfused tissues. This was confirmed by researchers, who measured which proteins in the cells of the cartilage would be affected by the action of chondroitin sulfate13. According to the researchers chondroitin is one of the slow-acting drugs that are already used clinically in treating arthritis and osteoarthritis.

Anti-inflammatory effect shown in clinical studies

Chondroitin is an Effective Anti-inflammatory

Arthritis and osteoarthritis are similar in that both are characterised by the chronic inflammatory processes that break down joint cartilage, leading to swelling and severe pain. These processes are caused by the body’s own immune response.

Calamia and colleagues measured the degree of various bodily immune reactions in their trial. They stimulated cultured cartilage cells with an inflammatory factor and treated the cell culture with chondroitin sulfate. The control sample received no chondroitin.

Of the 75 proteins studied, 18 were changed under chondroitin therapy. Chondroitin acts by drawing fluid into cartilage cells which have no blood supply of their own, and acts as an anti-inflammatory. The researchers interpreted their results as showing that chondroitin sulfate may be a suitable therapeutic agent for arthritis and osteoarthritis, due to its versatile and positive effects on cartilage cells.

Use of chondroitin in veterinary medicine

Chondroitin sulfate is also effective on animals.

In a study using animals, chondroitin sulfate resulted in an improvement of the damage in the affected joints14. The research team conducted their research on guinea pigs that were given either glucosamine or chondroitin sulfate or neither of the two substances for a period of 18 months.

Recommendations for Treatment with Chondroitin

Extensive clinical research shows that chondroitin is a very safe dietary supplement. Dosages range from 300 mg per day to about 1,000 mg. The dose does not need to be distributed throughout the day, but can be taken once a day with water ideally before a meal.

It is a natural micronutrient so side-effects or interactions are extremely rare and may well be triggered by other causes. In this case the currently course of treatment should be stopped and the dosage discussed with a doctor.

A chain is only ever as strong as its weakest link. This applies also to the processes of maintaining cartilage and combatting inflammation.

Combination products are always superior to single-, or two-nutrient products, because the combined benefits of several beneficial micro nutrients provide a multi-faceted, complementary treatment for many factors, which may cause or contribute to the arthritis.
