Three new studies show nutrients reduced pain, increased movement and lowered risk for osteoarthritis (OA) of the knee.
In one study, 75 participants with OA of the knee took 100 mg or 250 mg of Boswellia serrata extract or a placebo for 90 days. Doctors measured blood and urine levels of an enzyme that destroys joint cartilage and found that as early as seven days into the treatment, those who were taking 250 mg of Boswellia serrata reported significantly less pain and better movement and had lower levels of the destructive enzyme. There were no safety issues or side effects.
In another study, 100 participants with OA of the knee took 150 mg of Pycnogenol per day with meals or a placebo. After three months, those who had taken Pycnogenol reported significantly less knee pain, better movement and that they were taking less prescription anti-inflammatory medication than before the study. The placebo group did not improve and took more anti-inflammatory drugs.
In a knee bone and cartilage study, researchers analyzed the amount of antioxidants in the diets of about 300 healthy men and women, average age 58, who did not have knee pain or injury. Ten years later, doctors took a magnetic resonance image (MRI) to determine knee bone and cartilage health. Those who consumed the most vitamin C and those who consumed the most fresh fruit, had healthier knee bone and marrow than did those who consumed less vitamin C or fresh fruit. Those who consumed the most lutein and zeaxanthin had healthier knee cartilage than those who consumed less lutein and zeaxanthin.
