Dietary Phytoestrogens and Bone Metabolism Clinical Trials Info presented on Clinical Trials Search isn't intended to be a substitute for qualified medical advice, visits or professional assistance by using a real mD. We are not docs. Always confer with your physician about Dietary Phytoestrogens and Bone Metabolism conditions. Clinical Trials Search.org is a website committed to listing clinical research studies in human subjects. Dietary Phytoestrogens and Bone Metabolism Clinical research trials and Dietary Phytoestrogens and Bone Metabolism health trials occur in many of cities throughout the US. A clinical trial or clinical study is a research project with human volunteer subjects. Clinical drug trials and pharmaceutical clinical trials generally evaluate the effectivity of new does drugs. The intent of the studies / undertakings is to resolve particular human health questions. Clinical trials are a popular way for physicians, government agencies, and private sector companies to detect remedies for all sorts of conditions, including Dietary Phytoestrogens and Bone Metabolism. Dietary Phytoestrogens and Bone Metabolism Clinical Trials and other clinical trials permit volunteers to obtain healthcare treatment alternatives before they are available to the masses. Most times the participants undergo professional assistance for without cost, and occasionally they are compensated for their time. Occasionally there is a cost for a Dietary Phytoestrogens and Bone Metabolism clinical trial. Test subjects typically receive the most expert healthcare available for their Dietary Phytoestrogens and Bone Metabolism condition. Dangers are a reality, however, and may include more or frequent mD visits, healthcare dangers (perhaps life-endangering), and/or the treatment being ineffectual. Trials are federally regulated with rigid guidelines to protect clinical trials patients.

Dietary Phytoestrogens and Bone Metabolism
For Condition: Osteoporosis
Status: Recruiting
Sponsor(s): National Center for Complementary and Alternative Medicine (NCCAM) ,
Synopsis: The purpose of this study is to determine whether dietary phytoestrogens are an effective alternative to postmenopausal exogenous estrogen replacement therapy in preventing bone loss.
Details: Osteoporosis in postmenopausal women is one of the most important public health challenges of our time. With millions of women affected and billions of dollars being spent for its complications, we need to develop effective approaches to this disease. Postmenopausal women are at particular risk because the loss of estrogen associated with the menopause leads to bone loss of much greater magnitude than one would expect on the basis of age alone. Estrogen replacement therapy, a logical and effective therapeutic approach, has been associated with serious concerns about adverse events and, thus, limited use. The recent development of selective estrogen receptor modulators (SERMS) may help if they continue to show promise. Interest in natural sources of estrogenic substances to prevent postmenopausal bone loss is an expected outgrowth of the general interest in alternative medicinals for a wide variety of human disorders. Concerns about the potential for adverse consequences of the conventional use of estrogen replacement therapy, and limited knowledge about long term use of SERMS- add support to this quest. No systematic investigation of the role of dietary phytoestrogens on bone mass and skeletal dynamics has yet been conducted. With the dramatic increase in interest in these sources of estrogenic activity, it is important for us to determine whether these agents are efficacious. Otherwise, this field will be plagued for years to come by incomplete, anecdotal and scientifically poorly documented actions of these agents on bone metabolism. It is our expectation that this study will begin to provide the documentary information that the field so clearly needs. The rationale for exploring the potential for phytoestrogens in the maintenance of skeletal health in postmenopausal women is clear and compelling. Women will be randomly assigned to one of three healthy eating plans and, over the course of the year-long study, will learn to choose and cook foods to help optimize health as they go through menopause and beyond.
