Beta-sitosterol is also found in common foods we eat every day but in even smaller amounts than the above mentioned herbs. It is completely safe and without any side effects.

The chemical structure of beta-sitosterol is similar to that of cholesterol . . . the main difference being the presence of an extra ethyl group.

When it comes to supporting prostate health, there isn't any natural supplement, that has been studied more extensively than beta sitoterol, which is why it has been a key ingredient in Prostate Miracle® since 2003.

For well over twenty years, the role beta-sitosterol plays in supporting prostate health has been studied extensively. Numerous international scientific journals including "European Patent", "European Journal of Drug Metab", "International Journal of Immunopharmacol", "Anticancer Research", "The Lancet", "European Urology", "Minerva Urologia", "British Journal of Clinical Pharmacology", "Medizinische Klinik", "Fortsher Med". and many others, have all published their very impressive findings.

There is a great deal of confusion, regarding the terms: phytosterols, phytosterol complex, beta sitosterol and beta sitosterol complex. Much of this confusion is propagated by some of new prostate formula companies, who misuse these terms in order to misrepresent their formulas as being "stronger".

In order to intelligently compare "apples to apples", it is important to clarify these terms. To set the record straight . . . Phytosterols (also known as plant sterols) are a group of steroid alcohols, which occur naturally in plants. Included in this group are the sterols: Beta Sitosterol, Campesterol, Stigmasterol, Brasicasterol; as well as the stanols: Campestanol and Stigmastanol. Of all the components in this phytosterol mix, Beta sitosterol is the most important one for supporting prostate health.

It is important to understand that beta sitosterol does not exist as an isolated raw material. Technically speaking the extracted form is always a phytosterol mix (aka a phytosterol complex), of which beta sitosterol is just one component. Sometimes this phytosterol mix is referred to as a beta sitosterol complex, but to describe it as beta sitosterol, is technically inaccurate and somewhat confusing, yet so commonly done in the natural health industry, that even we (with this explanation) use the terms interchangeably on our website.

The amount of beta sitosterol contained in any phytosterol complex, will depend on both the natural balance of the source material as well as the purity of the phytosterols, which is based on the quality and precision of the extraction process.

In previous years, beta sitosterol was often extracted from sugar cane, but today it is most commonly extracted from soy, with a phytosterol purity of up to 95% and typically containing 40-55% beta sitosterol.

The majority of beta sitosterol available in the USA today, is now being imported from China. ALL Chinese made beta sitosterol is extracted from soy. Many of the newer prostate formulas out there, use the cheaper Chinese made beta sitosterol. Ever since the early 1980s, when China first began competing in the raw materials sector of the U.S. nutrition industry, their quality control has come into question. Beta sitosterol and other raw materials exported from China are often contaminated with unacceptable levels of heavy metals or with the residues of herbicides or pesticides.

Chinese beta sitosterol clearly falls far below the standard we will accept for use in Prostate Miracle®.
