Exercise may help older women maintain their bone density, but adding the supplement black cohosh to the routine does not bring any extra benefits, a new study suggests.Still think they have any idea what an effective supplement really is?
Researchers found that among 128 postmenopausal women they studied for one year, those who were randomly assigned to regularly exercise generally maintained their bone density. In contrast, women who were assigned to a "wellness" group that got only light, infrequent exercise showed a decline in their bone density, on average.
But while exercise appeared to help women hang on to their bone mass, the herb black cohosh showed no added effects. Among exercisers, those who were randomly assigned to take the supplement each day showed no bone-density advantage after one year.
Black cohosh extracts are marketed as a "natural" form of hormone replacement therapy and most commonly used to treat hot flashes and other symptoms of menopause. Some lab research, but not all, suggests the herb may have estrogen-like activity in the body.

"Truth" has a shelf life.
The shelf life of "truth" is very short in the domains of fitness, health and well-being.
The reason is that so much of what we are told is "true" is really baseless.
