Ingredients

Benefits Effective Prostate Support Saw palmetto extract is one of the world's leading herbal products for prostate support. Widely-cited clinical studies conducted over the last fifteen years have clearly established the ability of Saw palmetto extract to produce major improvements in prostate-related urinary function. Saw Palmetto's key active ingredients help to normalize prostate gland structure. Discussion As men pass through and beyond middle age, hormonal changes occur which can impact the prostate gland. Levels of dihydrotestoterone (DHT), a normal metabolite of testosterone, increase. This, plus an increased binding of DHT to nuclear receptors in the prostate cell, results in growth of prostate tissue. This tissue growth takes place in the part of the prostate which surrounds the urethra, the tube for urine excretion. This can constrict the urethra, resulting in urinary disturbances. Saw palmetto extract has been shown to inhibit 5 alpha-reductase, an enzyme that controls conversion of testosterone to DHT. Saw palmetto extract also blocks the binding of DHT to prostate cells. These mechanisms are believed to account for Saw palmetto extract's positive effect on prostate gland structure. In clinical studies, Saw palmetto extract has produced measurable improvements in urinary functions and prostate size. Quality of life scores have also improved. The results with Saw palmetto extract have been duplicated in open trials and controlled, double-blind studies. Saw palmetto extract is safe and virtually free of side-effects. Saw palmetto’s effectiveness comes from its content of natural fatty acids and sterols. These include oleic acid, lauric acid, campasterol, stigmasterol, beta-sitosterol and others. The standard of quality for Saw palmetto extract products is a high concentration of fatty acids and sterols, equaling 90%.

Safety Suggested Adult Use: One to capsule daily with food.

Scientific References 1. Braeckman, J., 'The extract of Serenoa repens in the treatment of benign prostatic hyperplasia: a multicenter open study,' Current Therapeutic Research 1994: 55(7):776-85. Abstract Because prostatic surgery is not the treatment of choice for most patients with benign prostatic hyperplasia (BPH), the therapeutic effect of a 160 mg, twice daily, oral dose of Serenoa repens extract was studied during a 3-month open trial in 505 patients with mild to moderate symptoms of BPH. The efficacy of the regimen was evaluated in 305 of these patients. Traditional parameters for quantifying prostatism, such as the International Prostate Symptom Score, the quality of life score, urinary flow rates, residual urinary volume, and prostate size, were found to be significantly improved after only 45 days of treatment. After 90 days of treatment, a majority of patients (88%) and treating physicians (88%) considered the therapy effective. In addition, the serum prostate-specific antigen concentration was not modified by the drug, thus limiting the risk of masking any possible development of prostate cancer during treatment. The incidence of side effects (5%) was low and compares favorably with that reported for existing therapies used in BPH patients. The extract of Serenoa repens appears to be an effective and well-tolerated pharmacologic agent in treating the mictional problems accompanying BPH. 2.
