Published studies suggest that many men endure some form of prostate-induced discomfort during their lives. Saw palmetto has been proven to be the gold standard in natural prostate support. Life Extension offers an ultra-high potency formula unlike typical saw palmetto extracts. The saw palmetto berry (Serenoa repens) is rich in bioactive, high-molecular weight compounds, including beta-sitosterol. It has been shown to inhibit alpha-adrenergic receptor activity (to support normal urinary flow) and help regulate inflammation in the prostate gland. DeepExtract™ is a patented CO2 extraction technology that closely reflects the composition of premium, mature saw palmetto berries. The result is a superior formula containing key ingredients in higher concentrations than many other extracts. Super Saw Palmetto/Nettle Root Formula with Beta-Sitosterol combines the USPlus saw palmetto CO2 DeepExtract with a nettle root extract (Urtica dioica), boron and rosemary to support a healthy prostate. Testosterone converts to oestrogen at higher rates as men age. Prostate cells are sensitive to oestrogen’s growth effects. Nettle root helps support prostate cells against the excess oestrogen levels. This formula contains saw palmetto extract standardized to contain 136 milligrams total fatty acids and 45 milligrams of beta -sitosterol from pine per one softgel.
