ProStat Plus combines standardized extracts of saw palmetto, stinging nettles, and pygeum, along with beta-sitosterol, zinc, and amino acids, to provide comprehensive support for male genitourinary health. Saw Palmetto has demonstrated an ability to inhibit the 5-alpha reductase enzyme and produce anti-hormonal effects on prostate function. Studies have also demonstrated that pygeum and stinging nettles can support prostate wellness. Beta-sitosterol, a constituent of saw palmetto and pygeum, is backed by research indicating it helps maintain healthy urinary flow, as do the amino acids alanine, glycine, and glutamic acid.*
