Not all ingredients are created equal. While developing NATRXA we sought to find only those ingredients, no matter the cost, which are clinically proven and have the science to back up their claims.

Beta-sitosterol

Beta-sitosterol is classified as a noncholesterol sterol, or neutral sterol. However, it is structurally similar to cholesterol, and it is the main sterol in the Western diet. Some evidence suggests that Americans consume about 165 milligrams of beta-sitosterol daily. Beta-sitosterol and beta-sitosterol glucoside are found in the tissue, plasma, and feces of healthy individuals. The average content of plant sterols found in the plasma of healthy Western individuals is one milligram per deciliter.

Beta-sitosterol is found in plant-based foods, such as fruits, vegetables, soybeans, breads, peanuts, and peanut products. Beta-sitosterol is also present in bourbon and oils, such as olive, flaxseed, and tuna. Plant oils contain the highest concentration of phytosterols. Nuts and seeds contain moderate amounts of phytosterols, while fruits and vegetables generally contain the lowest phytosterol concentrations. For example, roasted peanuts contain 61-114 milligrams per 100 grams, 78-83% of which is in the form of beta-sitosterol. Peanut butter contains 144-157 milligrams per 100 grams. These values indicate that peanut products are a good source of phytosterols, specifically, beta-sitosterol. Avocados have also been identified as a good source of beta-sitosterol. Beta-sitosterol can also be derived from pulp and paper mill effluents.

Margarines enriched with phytosterol esters, including beta-sitosterol, have been marketed for their cholesterol-lowering effects. Sitosterols are also used in products for the treatment of other medical conditions, including, but not limited to, benign prostatic hyperplasia (BPH) and immune stimulation

How does Beta-sitosterol help BPH?
Beta-sitosterol and beta-sitosterol glucoside have been used to treat symptoms of BPH (enlarged prostate). Several clinical studies support this use, although the exact potential mechanism of action is unclear.

What is the recommended level of Beta-sitosterol?
60 mg per day

What drugs should not be taken with Beta-sitosterol?
Beta-sitosterol may increase the risk of bleeding when taken with drugs that increase the risk of bleeding. Some examples include aspirin, anticoagulants (blood thinners) such as warfarin (Coumadin®) or heparin, antiplatelet drugs such as clopidogrel (Plavix®), and nonsteroidal anti-inflammatory drugs such as ibuprofen (Motrin®, Advil®) or naproxen (Naprosyn®, Aleve®).
