News & Research:

  • Chrondroitin outperforms celecoxib in knee osteoarthritis study - Science Daily, 11/7/15 - "studied 194 people with knee OA and inflammation of the synovial membrane in the knee. The participants were followed for two years and were divided into two groups. The first group took 1200mg (pharmacological preparation) of chondroitin daily, and the second group took 200mg of celecoxib daily ... At both one and two years, the researchers found a better reduction of cartilage loss in the whole knee, and more particularly in the inner half, of the participants on chondroitin when compared to those on celecoxib. Additionally, there was a decrease in synovial membrane thickness in some of the participants on chondroitin, showing far better results for this group ... This study demonstrates that both chondroitin sulfate and celecoxib are equally effective at reducing the symptoms of knee OA patients. However, only chondroitin sulfate was found to be capable of slowing down the progression of the disease by reducing the loss of cartilage" - See chondroitin sulfate at Amazon.com.
  • Chondroitin/Glucosamine Reduced Pain in Knee Arthritis in RCT - Medscape, 1/30/15 - "a combination glucosamine/chondroitin sulfate product produced a 50.1% decrease in Western Ontario and McMaster OA index (WOMAC) pain, which is comparable to the 50.2% decrease seen in patients randomly assigned to receive celecoxib ... Patients received either chondroitin sulfate 400 mg plus glucosamine hydrochloride 500 mg (CS+GH; Droglican, Bioibérica SA) three times a day or celecoxib 200 mg every day for 6 months"
  • Association Between use of Specialty Dietary Supplements and C-Reactive Protein Concentrations - Medscape, 12/28/12 - "In summary, this study adds support to laboratory research and to some human studies which suggest that glucosamine, chondroitin, and fish oil may reduce systemic inflammation. In doing so, this study adds biologic plausibility to previous studies which have shown beneficial effects of these supplements on chronic diseases. Given the number of diseases with which inflammation is associated, such as cancer and cardiovascular disease, there is a need to find safe and effective ways to reduce inflammation. Research suggests that these 3 supplements have excellent safety profiles, [88–92] supporting their potential role in disease prevention" - See glucosamine products at Amazon.com, chondroitin sulfate at Amazon.com, Mega Twin EPA at Amazon.com and Jarrow Max DHA at Amazon.com.
  • Glucosamine, Chondroitin, Fish Oil May Reduce Inflammation - Medscape, 11/27/12 - "Inflammation is now recognized as a factor in cancer and cardiovascular disease as well as many rheumatoid diseases ... the researchers found hs-CRP reductions of 17% (95% confidence interval [CI], 7% - 26%) with glucosamine, 22% (95% CI, 8% - 33%) with chondroitin, and 16% (95% CI, 0.3% - 29%) with fish oil compared with participants who did not take the supplements"
  • In People with Hand Osteoarthritis, Chondroitin Sulphate Therapy for 6 Months Improves Pain and Function Compared With Placebo - Medscape, 11/20/12 - "Osteoarthritis of the finger joints is present in about 10% of individuals aged 40 to 49, rising to 92% in individuals over 70 years of age ... Patients were of either sex, aged 40 years and older and given 800 mg of chondroitin sulphate as a single tablet each day or placebo for a total period of 6 months. The chondroitin preparation contained highly purified chondroitins 4 and 6 sulphate of fish origin ... Improvement in the patient's assessment of global hand pain on the VAS was significantly more pronounced in the chondroitin sulphate group than in the placebo group. The decrease in the FIHOA score demonstrated similar pattern. The relative benefit of chondroitin sulphate on both primary end points became evident only after 3 months of treatment. No serious adverse reaction occurred in any study patients"
  • Joint Supplements for Aromatase Inhibitor Adverse Effects - Medscape, 11/18/11 - "Aromatase inhibitors are widely used in the treatment of breast cancer but are associated with significant musculoskeletal adverse effects, including joint pain and stiffness ... We know that these symptoms are unresponsive to conventional pain medication and often lead to low adherence to aromatase inhibitor therapy ... The cohort consisted of postmenopausal breast cancer patents with stage I to III disease who had been on aromatase therapy for at least 3 months, who reported a pain rating of 4 or higher on a 10-point visual analog scale, and whose pain worsened after initiating treatment with aromatase inhibitors if they had preexisting osteoarthritis ... Participants took 1500 mg/day of glucosamine and 1200 mg/day of chondroitin, and were evaluated every 6 weeks at the clinic ... There was a drop in pain and stiffness in the hips and knees at 12 and 24 weeks, as well as improvement in function. "This affected about 50% of the women," she explained. "We saw a very similar pattern looking at the hands and the wrist. We saw similar results with the Brief Pain/Stiffness Inventory — with about 35% to 50% of women.""
  • Chondroitin sulfate improves hand function, relieves morning stiffness caused by osteoarthritis, study finds - Science Daily, 9/6/11 - "OA -- the most common form of arthritis -- affects more than 27 million adults in the U.S., causing joint pain and stiffness ... 20% to 30% of adults have OA of the hand, with the prevalence rising to more than 50% after 60 years of age ... Participants received either 800 mg of chondroitin sulfate (80 patients) or placebo (82 patients) once daily for 6 months ... patients in the chondroitin sulfate group had significant decrease in global hand pain compared with the placebo group, reflecting an 8.7 decrease on the VAS. Hand function also improved significantly for those taking chondroitin sulfate, decreasing more than 2 points on the FIHOA. Researchers also reported significantly improved hand function and reduction in morning stiffness for participants taking chondroitin sulfate versus placebo ... Alternative therapies, such as nonsteroidal anti-inflammatory drugs (NSAIDs), provide similar pain reducing effects, but with considerably more long-term toxicities"
  • Chondroitin Slows Progression And Relieves Symptoms Of Knee Osteoarthritis - Science Daily, 1/29/09 - "long-term administration of CS over 2 years can prevent joint structure degradation in patients with knee OA ... Joint space loss was significantly reduced in the CS group, fewer patients had progression of joint space width, and CS reduced pain in those taking it compared to the placebo group. CS was well-tolerated and there were no significant differences in the frequency of adverse events between the two groups"
