FAQ
Beta-sitosterol is a type of phytosterol. Phytosterols are molecules that make up the cell membranes of plant cells. They are similar to cholesterol, which is found in animals. Beta-sitosterol is the most abundant plant sterol in the human diet. It is also present in several traditional medications, including saw palmetto and devil’s claw (4).
There are reports that beta-sitosterol is effective at decreasing cholesterol levels. Because beta-sitosterol is similar to cholesterol, it competes with cholesterol for absorption in the digestive system. One study found that intake of moderate to high doses of phytosterols led to decreased intestinal absorption and increased fecal excretion of cholesterol. It also found that the highest dose of phytosterol (2,059 mg per day) led to a decrease in LDL cholesterol levels (5). Beta-sitosterol has also been shown to have anti-inflammatory and pain control effects in animals (4).
Beta-sitosterol also has the following health benefits, which is why it was chosen to be an ingredient in the Ro's Prostate Health supplement:
Beta-sitosterol is best known for its potential ability to relieve urinary symptoms that may affect many men as they age. Specifically, beta-sitosterol has been tested to see if it can improve lower urinary tract symptoms (LUTS). One review from 1999 looked at four different studies on beta-sitosterol in men with benign prostatic hyperplasia (BPH). The review found that supplementation led to improved urinary symptom scores and improved urinary flow. However, beta-sitosterol was not seen to decrease the size of the prostate (6).
Nutritional supplements, like beta-sitosterol, are not reviewed by the FDA for safety and effectiveness. The effective daily dose can therefore only be estimated based on what has been tested in studies. One study looked at the effects of supplementation with 20 mg three times per day (1) while another study looked at the effects of 180 mg in two or three divided doses per day (2).
Beta-sitosterol is available on its own in capsule form. Alternatively, beta-sitosterol can be a component of other supplements, such as saw palmetto.
Ro obtains beta-sitosterol from a source in the USA. The beta-sitosterol is PCR negative and comes from phytosterols in soy.
Ro offers beta-sitosterol in the following supplements:
