Swanson Herbal Prostate Complex is formulated with 3 naturally-sourced herbs to support prostate health and urinary tract health, plus a healthy urinary flow and frequency. Saw palmetto helps promote healthy urinary tract flow and frequency, as well as male hormonal balance. Early research suggests stinging nettle leaf in combination with saw palmetto may support urinary tract health in those with prostate health concerns. Pygeum bark and root extract from the Pygeum africanum tree has a long history of use for promoting prostate and urinary tract health. Each 2-capsule serving of Swanson Herbal Prostate Complex contains saw palmetto (Serenoa repens, berries) 562 mg, Pygeum africanum (bark) 462 mg, and stinging nettles root 4:1 extract (Urtica dioica) 66 mg.
