Phytosterol Complex, Beta Sitosterol
Developed by Ray-Sahelian, M.D.

Phytosterols are natural components of many vegetables and grains. Preliminary scientific evidence suggests that plant phytosterols may help to maintain cholesterol levels already within the normal range when consumed as part of a low cholesterol dietary program. The three main phytosterols in phytosterol complex are beta-sitosterol, campesterol, and stigmasterol. They are natural, safe and derived entirely from plant sources. Take a look at a popular prostate formula with beta sitosterol called Prostate Power Rx.

Beta Sitosterol Research Update
Cicero AF. Effects of a new soy/beta-sitosterol supplement on plasma lipids in moderately hypercholesterolemic subjects. J Am Diet Assoc 2002 Dec;102(12):1807-11. Atherosclerosis and Dysmetabolic Disease Study Center G. Descovich, Clinical Medicine and Applied Biotechnologies D. Campanacci, University of Bologna, Italy.
Our aim was to test the hypocholesterolemic effect of a low-dose formulation of soy proteins supplemented with isolated b-sitosterol in a ratio of 4:1 in 20 moderately hypercholesterolemic subjects. The study has been divided in three different periods of forty days each: a stabilization diet period, then a treatment period during which all subjects assumed 10 g one time a day of the tested product and, finally, a wash out period. From the end of the stabilization diet period to the end of the soy protein added in b-sitosterol supplementation we observed a 0.45 +/- 0.30 mmol/L, 0.09 +/- 0.31 mmol/L and 0.17 +/- 0.22 mmol/L mean +/- SE decrease in respectively LDL-C, TG and apoB levels, associated with a 0.12 +/- 0.25 and 0.03 +/- 0.51 mg/dL mean increase respectively in HDL-C and apoA plasma concentrations. According to this recommends, low doses of soy protein added in b-sitosterol seems to be a practical and safe alternative for patients seeking modest reductions in LDL-C (< 15%).

Preuss HG. Randomized trial of a combination of natural products (cernitin, saw palmetto, B-sitosterol, vitamin E) on symptoms of benign prostatic hyperplasia (BPH). Int Urol Nephrol 2001;33(2):217-25. Department of Physiology and Biophysics, Georgetown University Medical Center, Washington, DC 20007, USA.
Because benign prostatic hyperplasia (BPH) is relatively common, it is important to discover safe and effective means to treat this often debilitating perturbation. Accordingly, we examined the effectiveness of a combination of natural products (cernitin, saw palmetto, B-sitosterol, vitamin E) in treating symptoms of BPH. We undertook a randomized, placebo-controlled, double-blind study. Patients were enrolled from 3 urological practices in the USA. 144 subjects were randomized for study. 17 subjects eventually withdrew, leaving 70 patients in the test group and 57 in the placebo group to complete the study. Inclusion criteria consisted of a diagnosis of BPH, no evidence of cancer, and a maximal urinary flow rate between 5 and 15 ml/second. Patients received either placebo or the combined natural products for 3 months. Evaluations were performed via the American Urological Association (AUA) Symptom Index score, urinary flow rate, PSA measurement, and residual bladder volume. Nocturia showed a markedly significant decrease in severity in patients receiving the combined natural products compared to those taking placebo (p < 0.001). Daytime frequency was also lessened significantly (p < 0.04). When the average individual total AUA Symptom Index score in the test group was compared to that in the placebo group at the end of the study, the difference proved highly significant (p < 0.014). PSA measurements, maximal and average urinary flow rates, and residual volumes showed no statistically significant differences. When taken for 3 months, a combination of natural products (cernitin, saw palmetto, B-sitosterol, vitamin E) compared to placebo can significantly lessen nocturia and frequency and diminish overall symptomatology of BPH as indicated by an improvement in the total AUA Symptom Index score. The combination of natural products caused no significant adverse side effects.

Beta Sitosterol supplement pill questions
Q. I was diagnosed with prostate cancer February 2006. Have been taking supplements and monitoring progress of cancer. Taking beta-sitosterol from New Vitality. Unfortunately, New Vitality includes in their formula zinc and selenium and other metals. My doctor in Los Angeles last year warned me about zinc aggravating prostate cancer. Then I just read in a health magazine a few days ago that zinc, selenium, and one other element were implicated in doubling the risk of fatal prostate cancer disease. I am interested in knowing where I can get my hands on beta-sitosterol without zinc, selenium and other metals. Is the Physician Formulas beta sitosterol free of such elements?
   A. Yes, the Physician Formulas beta sitosterol does not have zinc or selenium. However, long term human studies are needed to determine whether the claims that zinc and selenium increase prostate cancer risk are valid claims or premature cautions.

Q. I am keen to start using the beta sitsterol only for prostate health, since I read so much about it. Are your beta sitosterol natural as well as the curcumin  / turmeric extract. Would these interfere with medications such as thyroxin and a prostate medication called cardura – to relax the bladder and urethra muscles. Does the beta sitosterol inhibit the conversion of testosterone to DHT via the enzyme 5 – alpha reductase.
   A. Yes, beta stiosterol and curcumin are natural. As far as interference with Cardura or other medicines, that is an area that has not been studied so we don't have a good answer. One small human study with only a few men has shown that beta sitosterol interferes with the conversion of testosterone to DHT, but until more long term human studies are done, it is not possible to say for sure how effective a beta sitosterol supplement is in terms of hair loss or prostate enlargement inhibition.

Q. Does sitosterol improve sexual health?
   A. It's hard to say. Short term use does not seem to have a strong influence on sexuality.
