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.

What is Saw Palmetto?

Saw palmetto (Serenoa repens, Sabal serrulata) is used popularly in Europe for symptoms associated with benign prostatic hypertrophy (enlargement of the prostate). Numerous human trials report that saw palmetto improves symptoms of benign prostatic hypertrophy (BPH) such as nighttime urination, urinary flow, and overall quality of life, although it may not greatly reduce the size of the prostate. The effectiveness may be similar to the medication finasteride (Proscar®) with fewer side effects. Although the quality of these studies has been variable, overall they suggest effectiveness.

Multiple mechanisms of action have been proposed, and saw palmetto appears to possess 5-α-reductase inhibitory activity (thereby preventing the conversion of testosterone to dihydrotestosterone). Hormonal/estrogenic effects have also been reported, as well as direct inhibitory effects on androgen receptors and anti-inflammatory properties.

How much do you need for adults?

For enlarged prostate (benign prostatic hypertrophy), a dose of 320 milligrams daily, in one dose or two divided doses.

With which drugs should Saw Palmetto not be taken?

Saw palmetto should not be taken with drugs that affect the levels of male sex hormones (androgens), such as finasteride (Proscar®, Propecia®) or flutamide (Eulexin®). In theory, saw palmetto may interfere with birth control pills or hormone replacement therapy in women. Tinctures may contain high levels of alcohol and may cause nausea or vomiting when taken with metronidazole (Flagyl®) or disulfiram (Antabuse®).
