Vitamin D and Knee Arthritis?

Can taking vitamin D reduce the pain and progression of osteoarthritis of the knee? A new study found no benefit for people who already had sufficient levels of vitamin D. In fact, these people needed more anti-inflammatory medication during the study than those given placebo. However, as seen in many other studies of vitamin D, people who entered the study deficient in vitamin D appeared to benefit from being given vitamin D, experiencing reduced pain. For more details, see the update in the Vitamin D Supplements Review, which includes our tests of vitamin D supplements. If you suffer from osteoarthritis of the knee or other joints, also read about glucosamine and chondroitin, as supplements with these ingredients may help. We have tested many of these products.

Be Careful with Iodine -- Especially If You're Pregnant

Unlike over-the-counter medicines, dietary supplements are generally not required to carry warning labels, even if they contain toxic amounts of ingredients. If you don't know how much of a vitamin, mineral, or other ingredient you really need, it's easily possible to get too much. This is what seems to have happened to some pregnant women taking a widely-sold iodine supplement, according to a recent medical report. Just one tablet contained 57 times the daily iodine they needed and more than ten times the limit associated with increased risk of toxicity. Their children were born with congenital hypothyroidism, apparently due to getting too much iodine from their mothers.

Find out which product these women took in the updated Iodine section of the Multivitamin Supplements Review. You'll also find appropriate levels of other vitamins and minerals and see which products in the Review did or did not exceed tolerable intake levels of vitamins and minerals. More >>

Glucosamine & Chondroitin Help Maintain Knee Joint

A 2-year study in people with osteoarthritis of the knee found that those who took a combination of glucosamine and chondroitin had only half the amount of narrowing of the knee joint space as those who took placebo. This beneficial finding differs from that of another large study published several years ago which did not find a benefit on joint space. The new study used a different form of glucosamine than the previous study. Get the details, as well as our tests of supplements with these ingredients, in the updated Joint Health Supplements Review (Glucosamine, Chondroitin, MSM and Boswellia) >>
