Although vitamin D is essential to bone health, a controlled clinical trial published online by JAMA Internal Medicine on Aug. 3, 2015, found that vitamin D supplements didn't build bone in postmenopausal women with blood levels of vitamin D below the 30-ng/mL threshold generally considered necessary for good health. Researchers at the University of Wisconsin randomly assigned 230 women to three groups: one got 800 IU of vitamin D daily and a placebo twice a month; one got a placebo daily and 50,000 IU of vitamin D twice a month; the third got placebos both daily and twice a month. The study lasted a year. The researchers found that neither dose of vitamin D had a significant effect on bone mass, falls, or fractures.

The Wisconsin study may not have used the right doses of vitamin D or lasted long enough to show an effect. One ongoing study, The Vitamin D and Omega-3 Trial (VITAL), is large enough to demonstrate even small-to-moderate benefits of vitamin D supplementation. VITAL is evaluating a 2,000-IU daily dose for five years in 26,000 women and men. The results are expected in 2017. Until then, it's still important to get the recommended daily dose of vitamin D: 600 IU for adults through age 70 and 800 IU for people ages 71 or older

Depression is fairly common among people suffering with rheumatoid arthritis (RA). Recent research suggests that depression may worsen RA symptoms and even make medications less effective. To date, the studies that indicate a connection between the severity of RA symptoms and depression have not been conclusive, so more research is needed. In the meantime, if you have RA and notice signs of depression, be sure to talk with your doctor.

For many women, bunions and rigidity are two of the most common—and painful—problems with the big toe. Both are easily treated.

Men also get osteoporosis—but consider your risk factors before deciding to have a bone-strength test.

Men's and women's bodies differ in plenty of ways, but we all have bones, and with aging they may lose some of their strength and leave us more vulnerable to dangerous fractures of the hip or spine. Osteoporosis is not exclusively a women's health issue.

Painful knees and sleeplessness often go hand in hand, but a form of counseling called cognitive behavioral therapy (CBT) can help with both problems, according to a study in Arthritis and Rheumatology.

The study involved 100 people ages 50 to 70 with wear-and-tear arthritis (osteoarthritis) in the knee as well as insomnia. They were chosen at random for either eight sessions of CBT or a comparison treatment, called desensitization therapy, known not to be very effective for insomnia.

A strong or weak hand grip carries more than just social cues. It may also help measure an individual’s risk for having a heart attack or stroke, or dying from cardiovascular disease. As part of the international Prospective Urban and Rural Epidemiological (PURE) study, researchers measured grip strength in nearly 140,000 adults in 17 countries and followed their health for an average of four years. Each 11-pound decrease in grip strength over the course of the study was linked to a 16% higher risk of dying from any cause, a 17% higher risk of dying from heart disease, a 9% higher risk of stroke, and a 7% higher risk of heart attack. Interestingly, grip strength was a better predictor of death or cardiovascular disease than blood pressure. What’s the connection? It’s possible that grip strength measures biological age.

A few simple measures can protect your most flexible joint and put it back in service after overuse or injury.

All you need to do is rotate your arm to realize what a marvel your shoulder is. It's the body's most flexible joint and one of the most essential. Whether you're reaching the top shelf, swinging a golf club, or washing your hair, "it's the one joint you can't stop using," says Karen Weber, a physical therapist at Harvard-affiliated Spaulding Rehabilitation Network. "We do a lot of repetitive motions with our arms. When our shoulder muscles aren't strong, we can set ourselves up for injury," Weber says.

Here are some steps you can take to reduce your reliance on medication to control symptoms and stay functional.

The pain from an arthritic knee can be intense, limiting daily activities and independence. Men can try a range of medications, but overall acetaminophen (Tylenol, other brands) appears to relieve pain only slightly better than a placebo pill, according to a research review in Annals of Internal Medicine.

The researchers pooled results from 137 randomized clinical trials involving about 33,000 people with knee arthritis and compared the relative effectiveness of the following treatments:

The telltale sign is leg pain and fatigue that comes on with activity and goes away with rest.
